PRECAUTION / NOTES
MANAGEMENT
SPECIAL CONSIDERATION
Introduction
Aspirin has the following pharmacological actions:
Analgesic
Antipyretic
Anti-inflammatory
Anti-platelet aggregation agent
Reduces mortality significantly in Acute Myocardial Infarction by minimising platelet aggregation and thrombus formation in order to retard the progression of coronary artery thrombosis.
Indications
Patients with suspected Acute Coronary Syndrome
Contraindications
Known hypersensitivity to aspirin / salicylates / NSAIDs
Children < 16 years of age.
Precautions / Notes
Actively bleeding peptic ulcers.
Suspected AAA.
Aspirin / salicylate-sensitive asthmatics
Management
300mg oral administration, preferably chewed.
Administered even if patient has taken aspirin that day or on anticoagulants (max of 300 mg)
Special Considerations

Increased bleeding time.
Anaphylactic reaction (some patients, especially asthmatics) exhibit notable sensitivity to aspirin, which may provoke various hypersensitivity / allergic reactions)
Atropine Sulphate
INTRODUCTION:
DOSAGE:
INDICATION:
CONTRAINDICATION
PRECAUTION / NOTES
MANAGEMENT
SPECIAL CONSIDERATION
Atropine Sulphate
Introduction
Dosage: 1.2mg in 1ml plastic vial
An anticholinergic agent that inhibits the action of acetylcholine on post ganglionic nerves at the neuroeffector site. This blocks vagal stimulation to allow the sympathetic response to increase pulse rate by increasing SA node firing rate, and increasing the conduction velocity through the AV node.
Competitively inhibits binding of acetylcholine to muscarinic receptors in the parasympathetic and central nervous systems
An antidote to reverse the effects of cholinesterase inhibitors such as seen with organophosphate poisoning.
Indications
Symptomatic Bradycardia, haemodynamically unstable due to the bradycardia and associated with poor signs of perfusion, including:
Cyanosis
Hypotension
Altered conscious state
Diaphoresis
Shortness of breath
Syncope
Organophosphate poisoning with cholinergic effects
Contraindications
Known hypersensitivity.
Patients with cardiac transplant.
Precautions / Notes
Monitoring: HR, BP, RR, GCS. It is advisable that a 12 Lead ECG is conducted prior to medication administration to rule out Acute Myocardial Infarction (STEMI) and Third-degree atrioventricular (AV) block (atropine may not be effective). If in doubt transmit 12-lead ECG to CSP SOC to discuss or seek ASMA advice.
Post ROSC bradycardia, isolated bradycardia or bradycardia linked to a traumatic cause does not indicate atropine.
Atropine treatment in patients with cardiac transplants is ineffective as vagus nerve is severed2
Reversible paediatric bradycardia (hypoxia, vagal stimulation) should have primary causes addressed before administering atropine
Caution in patients with Acute MI, (atropine may worsen ischemia and infarction)1, Myasthenia Gravis2 or severe inflammatory GI disease or GI obstruction2
Organophosphate poisoning atropine treatment target end points: HR > 80 bpm, SBP > 80 mmHg, drying of respiratory secretions.
Management
Symptomatic Bradycardia
IV/IO Injection

- Disturbed and Abnormal Behaviour (Generally RASS 1 ~ 3) where risk to safety is evident
- Dementia or frail patients where Olanzapine cannot be administered or is ineffective
CONTRAINDICATION:
Known allergy
Known Parkinson’s Disease
Where Ketamine has been administered to sedate this episode
Age < 6 years old
Post-ictal Disturbed & Abnormal Behaviour
Patients known or suspected to be pregnant
PRECAUTION / NOTES
Address organic causes for behavioural presentations at all times- eg. CVA, TBI, Hypoxia, Hypoglycaemia, etc
Post-ROSC agitation - consult ASMA / SOC CSP
Dementia patients - apply caution. Use lower doses
'Agitated or Excited Delirium', 'Acute Behavioural Disturbance' and 'Drug Induced Psychosis' are some alternative terms that may be used by other agencies
Sedation warnings
Sedation is HIGH RISK - must only be carried out after careful deliberation between officers and must not be based primarily at the request or influence of other agencies on scene (e.g. Police etc.)
Positive RASS score does not automatically infer a need to sedate
Age <16 years old - sedation should prompt a prior ASMA consult wherever practicable
Pregnant patients - STORC consult MUST be initiated prior to the decision to sedate in all cases where the patient is known or suspected to be pregnant. Transport of pregnant patients should be in the lateral position to prevent supine hypotension syndrome in any woman greater than 20 weeks gestation and to assist in managing airway secretions
ETOH / Intoxication - apply caution
Repeat & Maintenance doses - have a low threshold to consult with ASMA where repeat or maintenance doses are required
Monitoring – SpO2 and EtCO2 monitoring must be applied whenever level of consciousness drops (~RASS -2 or below)
Positioning – DO NOT transport in supine position (increases risk of laryngospasm from secretions) – transport in lateral position
Airway & Breathing – monitor airway and breathing effort, including chest movement closely for signs of impairment. Prepare to support if required
Restraint – Prone and/or handcuffed to rear carries excessive risk and MUST NOT occur. Physical restraint in any position that amplifies the risk of positional asphyxia, must be closely observed for signs of air hunger and hypoxia
RASS scores must be agreed and documented
Weight – Estimated weight must be agreed before administration of any weight based medicines. This must be documented
The final decision to sedate lies with the most senior clinician on scene
Administration limited to those with independent authority to practice per the Medications Schedule
Adults < 70 years old:
IM (preferred route):
5 mg in moderate to severe alcohol intoxication OR
10 mg in nil to mild alcohol intoxication

Glucagon
INTRODUCTION:
DOSAGE:
INDICATION:
CONTRAINDICATION
PRECAUTION / NOTES
MANAGEMENT
SPECIAL CONSIDERATION
Glucagon
Introduction
A hyperglycaemic agent that converts stored liver glycogen to glucose to increase blood glucose concentration and decreasing GI motility.
Dosage: 1 mg / Hypokit = 1 mg / 1 ml
Onset 4-7 minutes, duration 10-30 minutes.
Indications
For demonstrated hypoglycaemia where oral glucose cannot be administered and IV access cannot be obtained in a safe and timely manner.
Altered conscious state in a known diabetic or of otherwise unknown cause where blood glucose level is below 4mmol/L.
Contraindications
Hypersensitivity.
Known pheochromocytoma, insulinoma, glucagonoma
Precautions / Notes
Glucagon is effective in treating hypoglycaemia only if sufficient liver glycogen is present (eg: it does not work on alcohol or anorexia induced hypoglycaemia).
Even if fully recovered, patients should be encouraged to be transported to a medical facility to ensure effective follow up and review.
Management
Intramuscular injection into deltoid muscle or mid-lateral thigh
Adult:
1 mg (1 mL) IM
Response to glucagon should occur in 10 minutes; if no response, give IV glucose
If unable to obtain IV access, repeat IM glucagon after 10 minutes if patient still has inadequate GCS and blood glucose level.
Paediatric:
< 25 kg: 0.5 mg (0.5 mL) IM
> 25kg: 1 mg (1 mL) IM
Single dose only
Special Considerations
Nausea/vomiting

Glucose 10%
INTRODUCTION:
DOSAGE:
INDICATION:
CONTRAINDICATION
PRECAUTION / NOTES
MANAGEMENT
SPECIAL CONSIDERATION
Glucose (Intravenous)
Introduction
A hypertonic crystalloid solution that provides a readily available source of energy (Glucose)
Dosage: 500 ml of 10% Glucose = 10 grams in 100 mls
Indications
Demonstrated hypoglycaemia where oral glucose administration is inappropriate in a:
Altered conscious state in known diabetic or of otherwise unknown cause where blood glucose level is below 4mmol/L.
Cardiac arrest, only if hypoglycaemia is suspected as a contributory cause of the arrest, not an early indication.
Contraindications:
Not to be used if there is no patent IV access
Precautions / Notes
Patients should ideally be cannulated with a large gauge cannula into a large vein, with patency confirmed with a free flowing bolus (>20ml) of 0.9% normal saline, before administering glucose 10% using a 20ml syringe via the injection port, titrated to effect. Administration via an IO should utilise a 20ml syringe and a three way tap.
High concentration of IV glucose may aggravate dehydration due to its hypertonicity whereby it draws water from the cells.
IV glucose is corrosive and IV patency must be ensured before administration.
Careful titration of glucose in head injured patients is vital as glucose leaking into CNS tissue will aggravate the injury, resulting in cerebral oedema.
Monitor blood glucose level carefully; beware of drop in level again after the patient has recovered.
Even if fully recovered, patients should be encouraged to be transported to a medical facility to ensure effective follow up and review.
IO administration is only as a last resort after all other avenues have been exhausted and the patient needs lifesaving glucose.
Do not wait on scene for glucose to take effect.
Management
Adult:
- 15 g (150 mL) IV
- If BGL < 4 mmol/L after 5-10 minutes, give 10 g (100 mL) IV titrating to effect
Paediatric:
2 mL/kg (0.20g/kg or 200mg/kg) up to 15 g (150 mL) IV/IO
If BGL < 4 mmol/L after 5-10 minutes, repeat 2 mL/kg (0.20 g / kg or 200 mg/ kg) IV, titrating to effect
Newborn:
2 mL/kg (0.20 g/kg or 200 mg/kg)
Repeat once only, if clinically indicated (BGL < 2 mmol/L)

INDICATION:
CONTRAINDICATION
PRECAUTION / NOTES
MANAGEMENT
SPECIAL CONSIDERATION
Mode of Action/Medication Class
Rapid acting dissociative anaesthetic
IM onset: 5-10 minutes
IV onset: 1 minute
Use of a sedative agent should never be considered routine. Have a high threshold to offer or administer.
Indications
IV: Second line agent for severe pain of traumatic origin post IV Fentanyl administration. ASMA consult needed if IV Fentanyl minimum dose (age dependent as per CPG) has not been given prior to IV Ketamine administration
IM: First line agent for severe pain of traumatic origin should other means of administering pain medication not be available
Combative Traumatic Brain Injury
Paramedic only
(RASS 4) First line agent for severely disturbed or abnormal behaviour where there is an immediate risk to safety and rapid tranquilisation is required and no other sedative medications have already been administered to this patient
Sedation in Pregnancy: First line agent if olanzapine not suitable for sedation in pregnancy
CPR Induced Consciousness (CPRIC) where patient movement or other features are interfering with cardiac arrest management
Contraindications
Hypersensitivity
Active cardiovascular disease including cardiac chest pain, heart failure, severe or poorly controlled hypertension
Patients with delayed transfer of care (i.e. 'ramped')
Non-pregnant Disturbed and abnormal behaviour that are clearly not RASS 4 or where other sedative agents have already been administered (ASMA authority required)
Rapid Tranquilisation ONLY: Age < 16 years old
Age < 1 years old
PRECAUTION / NOTES
Caution in patients with stable psychiatric disorders such as Schizophrenia
Caution in patients with hyperthyroidism or receiving thyroid replacement due to increased risk of hypertension and tachycardia
Analgesia – IV Fentanyl minimum dose (age dependant as per CPG) should be given prior to IV Ketamine administration
Analgesia for Non traumatic pain (IM / IV / IO) in opioid-dependent patients – consider SOC CSP consult
Sedation warnings
Sedation is HIGH RISK – must only be carried out after careful deliberation between officers and must not be based primarily at the request or influence of other agencies on scene (e.g. Police etc.)
Positive RASS score does not automatically infer a need to sedate
Age <16 years old – sedation should prompt a prior ASMA consult wherever practicable
Pregnant patients - STORC consult MUST be initiated prior to the decision to sedate in all cases where the patient is known or suspected to be pregnant. Transport of pregnant patients should be in the lateral position to prevent supine hypotension syndrome in any woman greater than 20 weeks gestation and to assist in managing airway secretions
ETOH / Intoxication – apply caution
Repeat & Maintenance doses – have a low threshold to consult with ASMA where repeat or maintenance doses are required
Monitoring – SpO2 and EtCO2 monitoring must be applied whenever level of consciousness drops (~RASS -2 or below)
Positioning – DO NOT transport in supine position (increases risk of laryngospasm from secretions) – transport in lateral position
Airway & Breathing – monitor airway and breathing effort, including chest movement closely for signs of impairment. Prepare to support if required
Restraint – Prone and/or handcuffed to rear carries excessive risk and MUST NOT occur. Physical restraint in any position that amplifies the risk of positional asphyxia, must be closely observed for signs of air hunger and hypoxia
RASS scores must be agreed and documented
Weight – Estimated weight must be agreed before administration of any weight based medicines. This must be documented
The final decision to sedate lies with the most senior clinician on scene

INTRODUCTION:
DOSAGE:
INDICATION:
CONTRAINDICATION
PRECAUTION / NOTES
MANAGEMENT
SPECIAL CONSIDERATION
Midazolam
Introduction:
A water-soluble benzodiazepine that has anxiolytic, sedative and anticonvulsive characteristics. This is due to its bonding with receptors in the CNS; its action to increase the inhibitory effect of the g-aminobutyric acid (GABA) neurotransmitter on the GABA receptors and subsequent membrane threshold.
Midazolam is lipid-soluble in physiological pH and it reaches the CNS quickly.
Dosage: 15 mg in 3 mls
Indications:
Prolonged seizure activity - generalised seizure lasting ≥ 5 minutes OR recurrent / status seizure activity as per CPG
Focal seizure activity which is prolonged (≥ 5 minutes) and is associated with a GCS ≤ 12 as per CPG
ASMA consult required: Second-line IV agent for maintenance of sedation after Droperidol administration for Disturbed and/or Abnormal Behaviour
STORC consult required: Pregnant patients: Second-line IV agent for maintenance of sedation after Ketamine administration for Sedation in Pregnancy
Contraindications:
- Hypersensitivity
Use of Midazolam for sedation after Ketamine requires ASMA authority (non-pregnant patient) orSTORC consult (pregnant patients)
Precautions / Notes:
Early monitoring as soon as practicable is required when administering midazolam; including SpO2, respiratory rate, pulse and blood pressure
SpO2 and EtCO2 monitoring must be applied whenever level of consciousness drops consistent with the Sedative Warnings section below.
Psychostimulants, in toxic levels can produce severe agitation and psychotic behaviour
Paediatric patients:
Intramuscular administrations should always be prepared in a 1mL IM syringe
Have a low threshold to consult with ASMA when repeat or maintenance doses are required for sedation

Naloxone
INTRODUCTION:
DOSAGE:
INDICATION:
CONTRAINDICATION
PRECAUTION / NOTES
MANAGEMENT
SPECIAL CONSIDERATION
Naloxone
Introduction
Naloxone is a pure opioid antagonist that exerts its effect by competitive inhibition at the opioid receptor sites. It prevents or reverses the effects of opioids, including respiratory depression, sedation and hypotension. In the absence of opioids it exhibits essentially no pharmacological activity.
Dosage: 0.4 mg in 1 ml / TAKE HOME NALOXONE (1.8 mg naloxone)
Indications:
Reversal of respiratory depression in a suspected narcotic overdose.
Contraindications: Nil
Precautions / Notes:
- Polypharmacy overdose.
- Half-life of naloxone is < 1 hour; repeat doses may be required to maintain effect with longer acting opioids and those with active metabolites (e.g. methadone, diphenoxylate, codeine). Observe patients who respond to naloxone for 2-3 hours after administration for signs of re-narcotisation.
- Response to Naloxone is rapid; reconsider diagnosis if there is a failure to respond to 2 mg Naloxone.
- Patients may be aggressive post Naloxone and administration due to hypoxia. Scene safety and personal safety are paramount..
Management
Adult:
IM/IV/IO:
- 0.4-0.8 mg (400-800 microg) repeat dose every 2 minutes as required, titrated to clinical response to a maximum of 10 mg.
IN:
- One spray (1.8 mg) of Nyxoid® into nostril.
- Repeat at 2 minutes in opposite nostril if the patient does not respond.
Paediatric:
IM/IV/IO:
- 0.01 mg/kg (10 microg/kg, maximum dose 0.4 mg (400 microg), repeat every 2-3 minutes minutes as required, titrated to clinical response.
- If high suspicion of overdose, a 0.1 mg/kg (100 microg/kg) dose (maximum 2 mg) may be given following a lack of response to initial dose.
IN:
- One spray (1.8mg) of Nyxoid® into nostril.Repeat dose after 2 minutes if patient does not respond.
Special Considerations:
Withdrawal symptoms such as:
Aggression
Agitation
Nausea/vomiting
Dilated pupils and lacrimation
Take-Home-Naloxone (THN)
Total dispensed amount (3.6 mg - 2x 1.8 mg Sprays + Box with Instructions)
For patients that have required Naloxone, every attempt should be made to convince the 'at risk' patient to be transported to a healthcare facility.
Where attempts prove futile, IN Naloxone - Nyxoid® could be left with the patient. This is to avoid the risk of opioid related respiratory depression due to the short half-life of Naloxone.
In such circumstances please ensure to document leaving Nyxoid® with the person or a responsible other person in the PnT / ePCR.
Due to our SASA requirements, clinicians cannot supply scheduled medicines to persons who are not St John WA patients.

INDICATION:
CONTRAINDICATION
PRECAUTION / NOTES
MANAGEMENT
SPECIAL CONSIDERATION
Oxygen
Introduction
Oxygen is a treatment for hypoxaemia and has not been shown to have any effect on breathlessness in non-hypoxaemic patients.
Indications
Adult:
Oxygen should be titrated to achieve oxygen saturations of between 94 - 98%, (or 88 - 92% for COPD patients).
Paediatric:
All paediatric patients with significant illness or injury should receive oxygen. Newborn resuscitation should ideally be commenced with room air for the first couple of breaths.
Contraindications
- Explosive or flammable environments
- Normoxia
Precautions / Notes:
If the target saturations cannot be maintained with the nasal cannula or medium concentration mask then change to a non-rebreather oxygen mask.
Oxygen increases the toxicity in paraquat poisoning, target saturations of 88-92%.
Remember that some conditions can affect SpO2 readings e.g. carbon monoxide poisoning and cold digits
Management
Mask: Nasal cannulae
FIO2: 24% - 35%
Flow Rate: 1-4 lpm
Mask: Simple face mask
FIO2: 40% - 60%
Flow Rate: 5-8 lpm
Mask: Non-rebreather mask
FIO2: 60% - 100%
Flow Rate: 10-15 lpm
Mask: Bag Valve Mask
FIO2: 100%
Flow Rate: 15 lpm
Special Considerations
Patients with acute episodes of COPD are at risk of developing carbon dioxide retention if they are given excessive supplemental oxygen. This can cause acidosis and subsequent organ dysfunction.
High oxygen concentrations can lead to increased production of reactive free radicals resulting in cellular damage. This may be responsible for the detrimental effects observed with the use of high flow oxygen in myocardial infarction and stroke.

Age <12 months
Precautions / Notes
A spacer / MDI is the preferred route for Salbutamol administration where the patient presents with influenza like illness.
The use of a Metered Dose Inhaler (MDI) and spacer is equally as effective as nebulisation, in all asthma situations, where the patient is still able to adequately inhale.
Use of a nebuliser is recommended where the patient loses this ability.
Management:
MDI / Space chamber as per Clinical Skill
Adult/Child > 6 years:
4-12 puffs (400-1200 microg), repeat every 20 minutes (or sooner if needed) for the first hour
Paediatric < 6 years:
2-6 puffs (200-600 microg), repeat every 20 minutes (or sooner if needed) for the first hour
Using an MDI with spacer:
Press once firmly on the MDI to discharge 1 puff into the spacer
Instruct the patient to breathe in and out normally for 4 breaths
Repeat 1 puff at a time until the appropriate number of puffs have been taken
Repeat as clinically required as per dosing schedule above
Nebulised as per Clinical Skill:
Asthma
Adult/paediatric 6 years old or over:
5mg
Tranexamic Acid

INDICATION:
CONTRAINDICATION
PRECAUTION / NOTES
MANAGEMENT
SPECIAL CONSIDERATION
INTRODUCTION:
Antifibrinolytic
Tranexamic Acid (TXA) is a synthetic derivative of the amino acid lysine that inhibits fibrinolysis (clot breakdown) by blocking the lysine binding site on plasminogen, competitively inhibiting the activation of plasminogen to plasmin.
Hepatic metabolism with renal excretion.
Onset: Within minutes
Duration: 17 hours
Half-life: 3 hours
DOSAGE: 1 gram in 10 ml (100 mg / mls)
INDICATION:
Significant trauma (< 3 hours) with signs of hypovolaemia or
Significant active haemorrhage that requires the use ofo Tourniquet/so Haemostatic/pressure dressing/s
Suspected head injury (< 3hours) with GCS motor score of 4 (withdrawing from pain) or below
Severe Primary or Secondary Post-Partum Haemorrhage (> 1000 mL) or PPH with signs of hypovolaemia (birth/bleed occurred < 3hrs)
Significant post-tonsillectomy haemorrhage
CONTRAINDICATION
Known hypersensitivity to Tranexamic Acid.
Injury time more than 3 hours (associated with increase in mortality).
PRECAUTION / NOTES
TXA administration in the traumatic patient in the metropolitan area should ordinarily prompt transport to a major trauma centre
Rapid administration may lead to hypotension and dizziness.
Give as early as possible post event. Survival benefit is reduced by 10% for every fifteen minute delay with no benefit seen after 3 hours
Address critical interventions (airway management, control of major haemorrhage etc.) before administration of tranexamic acid.
Tranexamic acid administration should not delay transfer, noting it may be administered en route.
Safety during pregnancy has not been demonstrated, but the balance of risk is such that it should be administered if the indications are met in life threatening circumstances
For pregnant women with antepartum haemorrhage, consult with STORC if maternal compromise or peri arrest is apparent.
Subarachnoid haemorrhage; cerebral oedema or infarction may occur with IV administration2
Pre-hospital administration of TXA for non-traumatic haemorrhage (excluding PPH or post-tonsillectomy haemorrhage) is not currently supported and should not occur. Examples of non-traumatic haemorrhage include GI bleeding from causes such as peptic ulcers, varices and malignancy6
Adult IV / IO:
1 g slowly over 10 minutes (Rapid administration may cause hypotension)
SINGLE DOSE ONLY
Paediatric (<12 years) IV / IO:
15 mg/kg slowly over 10 minutes (max injection rate 50 mg/minute)

***Studies show that the humeral IO route is comparable to central venous drug delivery during CPR and should be selected in most non-paediatric cases. The tibial route is less effective and is de-emphisised.
***Select needle. This requires clinical judgement, taking into account the size of the bone and depth of overlying tissue. The following table is only a guide:
Pink = 15 mm = Minimal tissue (e.g. infant / paediatric tibia)
Blue = 25 mm = Minimal tissue (e.g. adult / paediatric tibia)
Yellow = 45 mm =Excessive tissue (e.g. humeral he
SITE SELECTION PROXIMAL HUMERUS
Place the patient's hand over the abdomen (elbow adducted and humerus internally rotated). Vasc - IO1
Palpate up the humerus (45° to the ground [the horizontal plane]) until you feel the surgical neck; the point at which you will begin to feel the 'ball' of the humerus.
Vasc - IO2
Palpate the insertion site 1 to 2cm above the surgical neck, into the greater tubercle ('ball' or humeral head).
Vasc - IO3
Once the insertion site has been prepared, insert the IO needle, angled slightly downwards and at 45° to the ground (horizontal plane)
SITE SELECTION: PROXIMAL TIBIA
*** Adult or Large Paediatric Patient
- Extend leg out straight.
- Palpate the tibial tuberosity. Locate the medial plateau site by moving two finger widths below the tibial tuberosity and then two finger widths medial along the flat aspect of the tibia.
- Insert needle 90° to bone.
*** Newborn, Infant or Paediatric Patient
- Extend leg out straight.
- Palpate the tibial tuberosity. Locate the medial plateau site by moving one finger width below the tibial tuberosity and then one finger width medially along the flat aspect of the tibia.
- Insert needle 90° to bone.
Direct Laryngoscopy & Magill Forceps
Indication:
Contraindication:
Patient Factors:
Procedure:
Discontinue:
Indication:
- To identify and remove a suspected foreign body from the hypopharynx that is preventing ventilation.
- In order to create a patent airway and an ability to achieve adequate ventilation
Contraindication:
- Conscious patient or Gag reflex intact
- Do not use Magill forceps if obstruction below the vocal cords.
- SpO2 reading of 90% and ventilation is achievable
- Suspected epiglottitis.
Patient Factors:
- Damage to upper respiratory tract, lips and teeth/dentures.
- Further impaction or crumbling of the foreign body
- Vagal stimulation
- Exacerbation of hypoxia / hypercapnia.
- Spinal injury
Procedure:
Prepare equipment required:
Laryngoscope
Magill forceps
Bag Valve Mask (BVM)
Oxygen Suction
*** Direct Laryngoscopy is a dynamic process that should start with properly positioning the patient in the Sniffing Position, but may require further position adjustment to achieve the required views.
In cardiac arrest due to foreign body airway obstruction, direct laryngoscopy & removal of foreign body MUST occur in conjunction with high quality chest compressions. Delayed ventilation (i.e. OPA/NPA with a non-rebreather mask) must NOT occur and ventilation must be commenced as soon as practicable.
Position the patient for optimal visualisation of the larynx (e.g sniff or pillow support)
Open patient's mouth by use of the cross finger technique, inspecting the oral cavity.
Suction if required
If the obstruction is visible and can be removed with the Magill forceps, proceed to Step 7.
Using left hand, place the laryngoscope blade into the right side of the patient's mouth, gently sweep the tongue to the left and position the blade midline in the mouth. Ensure any obstructions are not pushed further down the respiratory tract.
Advance the blade progressively down the tongue, exposing the obstructing o
Supraglottic Airway (SGA)
Indication:
Contraindication:
Patient Factors:
Procedure:
Discontinue:
Indication:
- To manage and maintain a compromised airway in the patient with absent pharyngeal and laryngeal reflexes.
Contraindication:
- Intact gag reflex
Patient Factors:
- Confirm LMA placement every time the patient is moved.
- Consider use of laryngoscope blade as tongue depressor in infants.
- Ensure the mask does not kink when advancing it into the patient's mouth.
Stabilise patient's head and neck to avoid flexion, rotation or traction.
- EtCO2 provides some analysis of ventilation and its use with SGA is advised.
- Utilise a 30:2 compression/ventilation regime during cardiac arrest when LMA is in use with LUCAS device.
Procedure:
Prepare equipment required:
i-gel®
Prepare equipment required:
Appropriate size i-gel®
BVM
Disposable catheter mount
Lubricant (NB: Back, both sides and tip)
Oxygen
Stethoscope
Airway support strap
Suction
EtCO2
Select i-gel® size:
Size Weight
3 30 - 60 kg
4 50 - 90 kg
Apply lubricant to posterior surface of i-gel®
Pre-oxygenate the patient
Ensure airway is clear.
Place patient's head in the 'sniffing' position using appropriate padding/ neutral position in suspected cervical spine trauma.
Push the mandible towards the thorax, insert the i-gel® into the patient's mouth (3) with the tip of the mask against the hard palate.
Glide the device as far as it will go along the hard palate until definitive resistance is felt.
Attach the catheter mount and EtCO2 to the i-gel®.
While stabilising the i-gel®, gently inflate the lungs to test for air entry and seal.
Auscultate chest to confirm placement.
Secure the i-gel® in a central position with securing strap.
The i-gel® forms a seal in the airway; this is referred to as a non-inflating cuff.
Discontinue:
- Ineffective ventilations (i.e.: adequate chest rise and fall) cannot be achieved. (Some air leakage can be expected)
Needle Thoracocentesis
Indication:
Contraindication:
Patient Factors:
Procedure:
Discontinue:
Indications:
Traumatic cardiac arrest with torso involvement
Contraindication:
- Patients not in cardiac arrest unless trained and authorised
- Consider ASMA consult in a patient with suspected tension pneumothorax and respiratory and/or haemodynamic compromise.
Patient Factors:
- Perform bilaterally in traumatic cardiac arrest
- A patient not in cardiac arrest can receive unilateral treatment on the affected side, with ASMA authorisation where applicable
- The site selected should be superior to the third rib to avoid trauma to intercostal blood vessels and nerves.
- Procedure can be repeated if tension pneumothorax redevelops.
- It is very difficult to detect breath sounds/chest rise and fall in Traumatic Cardiac Arrest, so tension pneumothorax should be assumed whenever there is trauma to the torso
- Use the angio cath 14g needle, as shorter cannulas are unlikely to penetrate into the plural space
Procedure:
All relevant infection control methods to be utilised.
Prepare equipment required:
Alcohol/betadine swab
Angio Cath 14g cannula**
10mL syringe & NaCl
Stethoscope
** Use an alternative size needle if the Angio-Cath is obviously too long for the anatomical features of the patient (e.g. younger / frail etc.)
Locate the specific landmark on the affected side: 2nd intercostal space, mid-clavicular line.
Clean the landmark site with an alcohol/betadine swab.
Connect the angio cath 14g cannula to the 10mL syringe.
Insert the needle at a 90° angle to the patient's chest wall.
While inserting the needle, aspirate the 10mL syringe. Resistance is felt until the cannula enters the pleural space and releases air and/or fluids.
Repeat procedure for opposing pleura.
Remove the needle leaving the cannula in place.
Re-evaluate the patient.
Auscultate the chest.
If found that the pneumothorax re-tensions:

FOREIGN BODY AIRWAY OBSTRUCTION
Foreign Body Airway Obstruction
Indications
Clear the airway of a foreign body and maintain a patent airway in the conscious patient and when to commence CPR
Procedure
Conscious patient with an effective cough/talking:
Continuously reassure patient.
Encourage coughing.
Allow patient to be in a position of comfort.
Do not encourage vomiting.
Conscious patient with an ineffective cough / not able to talk:
If cough is ineffective, position patient so that gravity assists in the procedure:
Give up to 5 back blows:
Adult [Image 1]
Paediatric [Image 2]
Infant [Image 3]
Back blows are between the scapulae at a 90° angle to the patients back.
Check for dislodgement between each back blow.
If still obstructed:
Perform up to 5 chest thrusts:
Adult [Image 4]
Paediatric [Image 5]
Infant [Image 6]
Paediatrics and Adults can have chest thrusts performed in the sitting or standing position.
Chest thrusts are sharper than CPR.
Check for dislodgement between each chest thrust.
If obstruction not dislodged and patient remains conscious, continue alternating 5 back blows with 5 chest thrusts until object dislodges.
Unconscious patient with an ineffective ventilations/breathing:
Commence CPR as per Cardiac Arrest Guidelines.
Advanced Care (AP)
As per Primary Care
Unconscious
If obstruction is visible above vocal chords – Follow Direct Laryngoscopy & Magill Forceps.
If obstructions is below the vocal cords, consider Endotracheal Intubation (ETI) aiming for an intentional right main bronchus intubation, only if appropriately trained and authorised.
Consider Cricothyrotomy (Vertical) if all methods and attempts are unsuccessful and patient is unconscious, and only appropriately trained and authorised. An immediate call to ASMA must occur.
Extended Care
As per Advanced Care and
Unconscious
If obstructions is below the vocal cords, consider Endotracheal Intubation (ETI) aiming for an intentional right main bronchus intubation, only if appropriately trained and authorised.
Success
Obstruction dislodged with effective ventilations achieved.
Continue with patient assessment and subsequent management.
Discontinue
If patient becomes unconscious/unresponsive, follow Cardiac Arrest Clinical Practice Guideline.
CRICOTHYROTOMY
Cricothyrotomy (Vertical)
Indications
Cant Intubate, Cant Oxygenate (CICO) situation with decreasing SpO2
Primary airway attempt if ETT, supraglottic airway or BVM is not feasible (e.g. massive facial trauma or burns)
Contraindications
Children < 6 years of age
Open tracheal injury
Patient Factors & Considerations
This procedure is largely tactile, and officers should not rely on vision alone as the surgical field may become obscured due to haemorrhage following incision.
Misplacement is a risk of Cricothyrotomy1:
As with endotracheal intubation, capnography is the gold standard for confirming correct ETT placement2. Regular confirmation of clinically appropriate waveform capnography and ETCO2 is mandatory3.
Should capnography provide a consistent waveform with a max. reading of ≤10mmHg complete a DOPES check3.
Surgical emphysema developing around the neck indicates incorrect pre-tracheal insertion of ETT.
Asymmetrical chest movement may indicate ETT placement into the right bronchus2.
Check ETT placement whenever the patient is moved. As a rule, the officer ventilating is to control patient movements.
Confirmatory checks should be done in a manner that minimises interruptions to chest compressions
If no improvement in oxygenation after ongoing ventilation, consider possible misplacement
Procedure
Verbalise to your team that you are going to undertake a surgical airway
Apply required Infection Prevention & Control measures as per policy
Maintain oxygenation and ventilation with BVM or supraglottic device as best as possible
Prepare the following equipment:
Bougie
Size 6 ETT
10mL syringe
Alcohol/betadine swab
BVM
Cobbs connector
Disposable scalpel
Artery forceps
Oxygen
Suction
Tape
End Tidal CO2 monitoring
Prepare the neck with antiseptic solution
Position patient with neck extended where possible
Right handed individuals – stand on right side of patient; left-handed individuals stand on left side of patient
With non-dominant (ND) hand, identify and stabilise the laryngeal cage with thumb and middle finger and, with the index finger, identify the landmarks of front of neck if possible (thyroid cartilage, cricoid cartilage and cricothyroid membrane) as per figure 1.
If laryngeal landmarks are not identifiable, make a longitudinal incision at least 3-4cm in length through the skin and subcutaneous tissue. Stabilise your dominant hand on the sternum of the patient when making the incision.
Separate soft tissue with either your fingers or artery forceps to identify underlying anatomical landmarks; specifically the cricothyroid membrane
Lift the ND index finger and using the scalpel, make a horizontal incision using the SERT technique
Stab – with the blade facing you, insert it horizontally until resistance of back wall is felt
Extend – continue the incision as far as possible until resistance of side wall of cartilaginous cage felt
Reverse – turn the blade 180o and extend incision to opposite wall of cartilaginous cage
Twist – rotate the blade vertically to create a triangular hole beside scalpel’s blade
Remove scalpel and dispose of safely.
Insert pinkie finger of ND hand into the incision and ensure you can feel the tracheal walls
Insert the bougie perpendicular to the alignment of the neck, along the pad of your pinkie finger, then rotate 90° to feed down the trachea to a depth of no more than 15cm (insertion further will eventually result in hold up in the small airways)
Railroad a lubricated size 6.0 ETT over the bougie until the balloon is in the airway and is no longer visible (rotation of ETT may be required to pass through skin into airway to mitigate hold-up)
Ensure ETT is held secure whilst balloon inflated and bougie removed
Attach to bacterial filter, capnography, cobb's connecter and BVM
Confirm placement with
Capnography reading with clinically appropriate waveform and amplitude, ongoing after 6 ventilations
Adequate and equal rise and fall of chest
Appropriate auscultation of the epigastrium and then left and right lung fields
Assess the wound for haemorrhage and manage accordingly - consider Adrenaline-soaked gauze if indicated.
Secure ETT with tape
Document confirmatory checks, and time from declaring CICO to first ventilation (if possible)
Success
Capnography reading with clinically appropriate waveform and amplitude, ongoing after 6 ventilations
WITH
Adequate and equal rise and fall of chest
Appropriate auscultation of the epigastrium and then left and right lung fields
Any of the above checks in the absence of appropriate capnography are NOT reliable indicators of correct ETT placement4. Checks should be documented.
VENTILATION EMERGENCY: DOPES
Ventilation Emergencies (DOPES)
Indications
To identify and rectify potential causes of ventilation problems in a sequential and structured manner.
Patient Factors & Considerations
Any ventilated patient MUST be escorted by either a doctor or nurse whom has sufficient knowledge of the operation of the ventilator and knows what to do in the case of ventilator malfunction.
If an officer finds themselves in a situation where a ventilator malfunctions during a transfer, they may be required to assist with the checking procedure.
Critical points for Patient Care Record Form:
Type of ventilator.
Reason for ventilating patient.
Patient’s main presenting problem and present condition.
Care given before Officer’s arrival.
Procedure
Checking for possible causes:
Primary attendant (e.g. doctor/nurse) to check operation of ventilator
Check ventilator tube for kinks.
Check oxygen supply:
Connection to outlet.
Switch to spare 'D' size cylinder if required.
Oxygen supply tube can be connected to the outlet on the front of the Oxy-Viva in place of flow-meter.
If unable to locate fault then ventilation will need to be provided manually using the Bag-Valve-Mask (BVM) connected to an oxygen supply flow-meter with regular oxygen tubing.
If on a ventilator, the patient will have an advanced airway in-situ, such as an Endotracheal Tube (ETT) or Supraglottic Airway (SGA). Medical personnel will need to secure the advanced airway before transitioning to the BVM.
Disconnect ventilator tubing from breathing tube and connect BVM using right-angled flexible connector if available.
Ventilate patient at appropriate rate; a doctor/nurse MAY ventilate, or request the officer ventilates, at rate different to those listed in the ventilation clinical skill.
Ensure that the doctor/nurse confirms that the advanced airway is still in-situ and ventilations are adequate.
Contact receiving facility to advise of ventilator malfunction.
Transport Priority 1.
D
Displacement
Look at airway device position, does it look displaced?
Complete confirmatory checks per skill to verify placement
Assess/consider ETT cuff inflation, depth, or oesophageal intubation.
Check placement after any patient movement.
O
Obstruction
Inability or severe resistance to ventilation is a very good indicator of obstruction.
P
Pneumothorax
Consider the signs and symptoms of pneumothorax/haemothorax.
Consider ventilator settings.
E
Equipment Failure
Consider failure of equipment starting from the oxygen cylinder straight through to the ETT and back again.
S
Secretions
Thick mucus might obstruct ETT.
Success
Restoration of effective ventilation/oxygenation
Confirmed placement of advanced airway device per skill (if applicable)
Modified Valsalva Manoeuvre
Indications
Patients requiring reversion of hemodynamically stable SVT (QRS interval <0.12 sec), confirmed by 12-lead analysis
Contraindications
Recent or current acute myocardial infarction
Severe coronary artery disease
Haemodynamic instability (i.e. systolic BP below 90mmHg)
Known glaucoma or retinal myopathy
Patient Factors & Considerations
The following side effects might be experienced by the patient when performing the Modified Valsalva Manoeuvre:
Dizziness
Hypotension
Syncope
Tinnitus
Headache
If patient is on the stretcher, procedure is only to be performed while stretcher is locked into ambulance or lowered to ground height.
Procedure
All relevant infection control methods are to be utilised.
Prepare equipment required:
10mL syringe
Oxygen tubing
Sphygmomanometer
Explain the procedure to the patient.
Position patient in a semi-recumbent position.
Ensure ECG monitor is attached, and that SVT has been confirmed with 12 Lead Analysis. Closely monitor all vital signs and 12-Lead ECG. Resuscitation equipment must be at hand as other arrhythmias may occur.
Consider IV access prior to performing procedure.
Patient position – Semi-recumbent
Connect the sphygmomanometer to the oxygen tubing.
Instruct the patient to take a deep breath in while placing the oxygen tubing in their mouth.
Instruct the patient to blow into the tubing and attempt to reach 40mmHg, maintaining pressure for 15 seconds.
Lower patient into a supine position with the legs raised (where possible) approx. 45 degrees (Trendelenburg position) for 15 secs.
Return the patient to a semi-recumbent position for 45 seconds
Re-assess 12 Lead ECG and all vital signs
If unsuccessful in the first instance the procedure can be repeated once.
If a sphygmomanometer is unavailable another method is to instruct the patient to try and blow the plunger of a 10mL syringe until movement is just seen for 15 seconds.
Success
Termination of supraventricular tachycardia.
Discontinue
After 2x attempts
If the patient becomes hemodynamically unstable at any point (i.e. systolic BP below 90mmHg)
Pressure Immobilisation Technique (P.I.T)
Indications
Bites and stings by the following creatures:
All Australian venomous snakes, including sea snakes.
Funnel Web spider.
Blue-ringed octopus.
Cone Shell.
Contraindications
Pressure Immobilization Technique (PIT) is not to be used on spider or insect bites (except the Funnel web spider).
Patient Factors & Considerations
The pressure immobilisation technique (PIT) retards the flow of lymph by which venoms gain access to the circulation. It has also been shown that there may be inactivation of certain venoms and venom components when the injected venom remains trapped in the tissues by the pressure bandage.
The Snakebite Bandage (with continuous indicator) is the preferred bandage to achieve optimal compression with the Pressure Immobilisation Technique.
In absence of the snakebite bandage, elastic bandages (10-15 cm wide) can be used and are preferred over crepe bandages. If neither are available, clothing or other material should be used.
The bandage should be applied over existing clothing if possible.
If the bite is not on the limb, firm direct pressure on the bite site may be useful.
Procedure
Resuscitation takes precedence over the PIT application, however PIT should be applied as soon as possible to minimise further venom flow.
Apply a broad elasticated pressure bandage (10-15cm wide) over the bite site as soon as possible.
A PIT BANDAGE SHOULD NEVER BE UTILISED AS A TORNIQUET, NOR SHOULD IT BE APPLIED TIGHT ENOUGH TO CREATE A TORNIQUET EFFECT.
Where bandage is in situ and is found to be loose or ineffective: place a PIT bandage directly over top of any in situ bandage
Apply a snakebite bandage, commencing at the distal end of the affected limb (i.e. fingers or toes of the bitten limb) and extending upwards, covering as much of the limb as possible.
Apply enough tension to the snakebite bandages so that the continuous indicator forms a 1.5cm x 1.5cm square, rather than a rectangle in it's un-stretched state. This indicates that firm compression is achieved in the limb.
If using elasticated bandages without the continuous compression indicator, the bandage should be firm and tight and you should be unable to easily slide a finger between the bandage and the skin. Application of this bandage should be a similar tightness as when bandaging a sprained joint.
Splint the limb.
Keep the patient and the limb completely at rest.
Assess arterial blood follow distal to pressure dressings via cap refill.
If there is neurovascular compromise after applying the pressure dressing, it may be be necessary to take down the dressing and reapply not as tight.
Troubleshooting:
If the patient develops new onset of neurovascular compromise (such as a capillary refill time greater than three seconds on the affected limb) and/or pain that is disproportionate to the presenting injury, the patient may be at risk of developing compartment syndrome. If this occurs, contact CSPSOC/ASMA for advice before removing the bandage. DO NOT REMOVE PRIOR TO RECIEVING ADVICE FROM CSPSOC/ASMA.
Extrication post-Motor Vehicle Collision
Description
Patients involved in motor vehicle collisions will either:
Self-extricate prior to emergency services arrival
Self-extricate with instruction from emergency services
Require manual extrication. These patients considered “entrapped"1
Trapped patients are more likely to have time-critical injuries and are at increased risk of death2 – entrapment time must be minimised.
Indications
Patients requiring extrication post motor vehicle collision
Patient Factors & Considerations
If a patient becomes time-critical at any point, extrication should be expedited
If unable to assess time criticality, assume patient is time-critical until proven otherwise
Clinical care should be limited to necessary interventions while a patient is entrapped, with consideration given to the benefit of the intervention vs the risk of prolonging entrapment time
For self-extricating patients, minimise distance from the vehicle to the end point
Procedure
Approach scene with caution and assess for danger
Perform a continuous dynamic risk assessment (hazards may change rapidly). Do not approach if unsafe to do so
Perform necessary clinical interventions where required
Instruct patients to self-extricate if they are:
Able to follow instructions AND
Able to safely mobilise (i.e. adequate baseline function and no injuries such as but not limited to femur or pelvic fractures that would hinder mobility)
If the patient is unable to self-extricate, determine if they are time-critical (any immediate life threat present such as major haemorrhage, occluded airway, absent or ineffective breathing, decreased level of consciousness)
Time-critical patient: Perform immediate “emergency” extrication and remove patient as soon as is safely possible. Gentle handling should be employed where possible, however speed is prioritised.
If the patient is not time-critical, develop a bespoke, patient centred extrication plan with the overarching goal being to appropriately minimise entrapment time
Clearly communicate extrication plan to other resources on scene, including verbalisation of patient conditions and desired timeframes for extrication.
Success
Patient extricated with entrapment time minimalised
Discontinue
If an initial extrication plan fails or is no longer appropriate, continue to communicate with other resources on scene (if present) to adapt the extrication plan
Additional Information
Self-extrication, where indicated, is the fastest method of extrication and associated with the least movement of the cervical spine1,3
Spinal cord injuries caused by motor vehicle accidents are rare, and when present, are usually found in conjunction with other time-critical traumatic injuries2
Basic hands-on assessments, such as palpation of pulses, evaluation of respiratory effort, and patient interaction is appropriate for the trapped patient4
Monitoring equipment that interferes with or delays the extrication process should be avoided, unless the clinical insight they provide outweighs the potential for delay4
SPINAL MOTION RESTRICTION
Description
Spinal motion restriction (SMR) refers to a spectrum of skills designed to decrease movement of the entire spinal column after injury
Indications
Patients requiring spinal motion restriction per Spinal Trauma guideline
Contraindications
Patients with isolated penetrating trauma (i.e. stab or gunshot wound to neck or torso with no blunt force involvement)1
Patient Factors & Considerations
Spinal motion restriction (SMR) stabilises the head, neck and torso - not just the cervical spine
SMR should be tailored to each patient and the available resources. SMR should not be prioritised over the management life-threatening conditions
Forceful application of SMR that is not tolerated will not benefit the patient. Tailor SMR to patient comfort – take particular care to not exacerbate pre-existing conditions
Note:
Safe work load of the extraction board: 220kg
Safe work load of the scoop stretcher: 159kg
Procedure
Employ all infection control measures.
Communicate with the patient:
Explain what SMR is and why it is being applied
Minimise patient movement:
Instruct the patient to self-splint and avoid movement
Aim to minimise episodes of manual handling / patient movement
Avoid rough driving
Employ gentle patient handling
Employ manual in-line stabilisation (MILS)
This can be performed by clamping hands on the patient’s shoulders and using hands/forearms to stabilise the head and neck, maintaining alignment with the shoulders and torso
Remember: the rest of the body should also be stabilised
MILS may be withheld when a conscious patient is still (i.e. no driving or moving of the stretcher etc.) and able to self-splint
Utilise Headblocks to minimise lateral movement of the head, if MILS is not feasible
The rest of the body should be secured to the same surface as the headblocks
Do not use if not tolerated by the patient
Position the patient neutrally where tolerated, using padding to increase comfort.
Elderly patients and patients with pre-existing conditions (i.e. ankylosing spondylitis, kyphosis, osteoporosis, rheumatoid arthritis etc.) may require tailored positioning and padding due to anatomical differences2,3
Do not force supine or uncomfortable positioning where this is not tolerated by the patient – consider the pre-injury body shape.
Patients with an acute traumatic brain injury or who are unable to tolerate neutral positioning may be positioned with a 30-degree tilt of the stretcher
Pregnant patients over 20 weeks gestation may be positioned with a left hip tilt to avoid aortocaval compression
Apply a Lanyard as a visual reminder that c-spine has not been cleared
Discontinue
Discontinue if patient no longer tolerates spinal motion restriction
Additional Information
Patients may self-extricate where able to mobilise safely and follow instruction to self-splint, per Extrication post motor vehicle collision skill
PELVIC SPLINT
Description
Pelvic injuries can be life-threatening and require rapid identification and management
Most pelvic injuries in younger patients are due to high-energy blunt trauma, although frail and older patients may sustain pelvic injuries from a low-energy mechanism1
Pelvic splinting may reduce blood loss and improve patient outcomes2
Indications
Mechanism of injury suggestive of pelvic fracture, and ANY of the following
Pain / tenderness / deformity of the pelvis or lower back OR
Altered level of consciousness OR
Distracting injuries OR
Haemodynamic instability
Contraindications
Isolated neck of femur fractures
Patient Factors & Considerations
Physical examination in isolation cannot be relied on to detect pelvic fractures, especially among patients with distracting injuries and altered mental status3
Patients too small for a T-POD® (generally this will be patients under 23kgs) should receive pelvic sheeting
Pelvic binding should be considered as an urgent intervention and applied as soon as is practicable4
Employ gentle patient handling and minimise movement (avoid log rolling)
Patients with pelvic injuries are at increased risk of concurrent abdominal and/or thoracic injuries5-7
Procedure
T-POD®
All relevant infection control methods to be utilised.
Prepare equipment required:
T-POD®
Extrication board/scoop stretcher
Trauma shears
Position patient supine
MUST be applied direct to skin (or nothing more than light underwear)
Slide the fabric belt under the patient legs and position accordingly
The centreline of the binder must be at the level of the greater trochanters and symphysis pubis, NOT at the level of the iliac crests.
Cut the T-POD to create a 15-20cm central gap
Apply the pulley system to each side of the T-POD with the velcro
Use the pull tab on the pulley system and slowly apply tension until adequate and/or anatomical alignment normalises
Do NOT over-tension - the edges should not meet
Secure the pulley string around tabs and secure with velcro
Ensure that two fingers can fit between the device and the patient and a gap remain
Place padding between legs and bind the knees together. Bind ankles together with figure eight bandaging
Record time of application if possible
Circumferential sheet method (for paediatric patient too small for T-POD®):
All relevant infection control methods to be utilised.
Prepare equipment required:
Sheet (folded to appropriate width for patient)
2 x Clamps
Place a folded sheet underneath the patient – the centreline should be at the level of the greater trochanters
Two team members should cross the sheet across the pubic symphysis and pull the sheet firmly, without over tensioning
Twist the ends together and secure with a clamp
Place padding between legs and bind the knees together. Bind ankles together with figure eight bandaging
Slishman Traction Splint
Indications
Immobilise Proximal 1/3 and mid-shaft femoral fractures.
Contraindications
No reported contraindications
Patient Factors & Considerations
Assess distal neurovascular observations:
Pulse, Colour / Warmth / Movement / Sensation (CWMS)
Compound fractures: being aware not to pull contaminates into the wound during traction
Can be used in the presence of ankle/lower leg injury, amputation and pelvic injury.
Procedure is under the control of the person applying manual traction.
Unilateral fracture, second splint required for bilateral fractures.
If TPOD being utilised, this needs to be applied before the Slishman traction splint
Procedure
Step 1: Attach Ankle Strap
Remove the ankle strap and end cap from the pole.
Unroll the ankle strap, wrap comfortably around the patient’s ankle with the end cap lateral and facing up to receive splint pole.
Securing it with the large Velcro attachment area
The ankle strap can be positioned proximal to the calf in lower limb injuries/amputation
Step 2: Attach Groin Strap
Rest the female buckle on the patient’s anterior thigh.
Slide the male end of the strap under and around the patient’s anterior thigh.
Secure the groin strap with the female end and adjust the length if needed until comfortably secured.
Step 3: Apply Coarse Traction
Release the lower black distal clamp and extend the distal pole.
Insert distal pole it into ankle strap end cap.
Apply coarse traction by extending the pole until resistance is felt, then tighten distal clamp.
Step 4: Apply Fine Traction
Open the top red proximal clamp.
Pull the traction cord that extends from the end of the pole until you have reached desired traction
To reach desired traction, resistance on the cord will be felt and potentially a reduction in pain for the patient
Tighten the red proximal clamp and release the traction cord
Step 5: Reassess and Monitor
Reassess the patient’s CWMS and pain level
Adjust traction as needed to minimize pain, while maintaining perfusion
For rotational stability, attach mid leg strap to splint and wrap (one or both legs) below the knee.
Additional information
Manual traction should be maintained while setting up and applying the splint
Prior to applying the splint, assess the patient’s circulation, sensory, and motor response and ensure you have all the components of the splint.
PERIPHERAL TOURNIQUET
Indications
Uncontrolled, life-threatening limb haemorrhage
Contraindications
Haemorrhage that can be controlled using other haemorrhage control measures
Patient Factors & Considerations
Do not apply a peripheral tourniquet over the top of a wound or joint
Procedure
All relevant infection control methods are to be utilised.
Expose injury and identify source of haemorrhage
Slip the C-A-T® device under the affected extremity and feed the self adhering band through the friction adapter buckle.
Position the C-A-T® device above the site of the uncontrolled haemorrhage leaving at least 5cm of uninjured skin between the C-A-T® and the wound site. Apply directly to skin surface and not over clothing if possible.
Pull the free running end of the self-adhering band tight.
Securely fasten self adhering band back onto itself.
Twist the windlass rod until the bleeding is controlled[1]. The tourniquet should be tight enough to stop all circulation to the injured limb and control the haemorrhage
Lock the rod in place with the windlass clip and secure the windlass rod with the windlass strap[2].
Place a tourniquet sticker on the patient in a visible area and record the date and time the tourniquet was applied. This should also be recorded on the space provided on the tourniquet.
At the earliest practicable opportunity, if feasible, call CSPSCC so that notification can be passed to state trauma consultant
Handover at hospital must include tourniquet location and application time. Do not cover with bandages or clothing.
Success
Haemorrhage from injured limb controlled
Discontinue
Haemorrhage from injured limb has not ceased;
Use the same procedure to place another peripheral tourniquet proximal to the first
Simultaneous wound packing and/or direct pressure
Priority 1 transport with prenotification and consideration of Major Trauma guidelines
WOUND PACKING
Indications
Traumatic haemorrhage requiring packing that is not controlled by basic haemorrhage control measures such as direct pressure
Contraindications
Sucking chest wounds
Eye wounds
Airway wounds
Wounds involving exposed organs (eg:bowel)
Patient Factors & Considerations
Wound packing carries risk of injury from exposed bone fragments. Apply caution.
Wound packing should not delay peripheral tourniquet placement where immediately indicated
Procedure
Preparation
Appropriate PPE required
Expose injury and identify source of bleeding
Procedure
Apply direct firm pressure on source of haemorrhage whilst preparing QuikClot (if authorised) or appropriate material (i.e. gauze/crepe bandage)
Pack chosen material directly into the wound at the source of haemorrhage (wound bed or vessel)
Ensure wound is filled with chosen material, so that internal pressure is adequate to control haemorrhage
Once the wound is firmly packed apply consistent pressure for at least 3 minutes or until bleeding stops
Reassess for further haemorrhage
Once haemorrhage has been controlled apply trauma/pressure bandage to maintain pressure, or continue to maintain direct pressure if needed
Success
Haemorrhage has been controlled
Discontinue
Haemorrhage has not been controlled:
Consider packing additional gauze/QuikClot into the cavity, increasing direct pressure and use of peripheral tourniquet if indicated
Consider Priority 1 transport with prenotification as apporpriate and consideration of major trauma critieria

DEFINITION OF CROUP
Croup, also known as laryngotracheobronchitis, is a type of respiratory infection that is usually caused by a virus. The infection leads to swelling inside the trachea, which interferes with normal breathing and produces the classic symptoms of "barking" cough, stridor, and a hoarse voice
CAUSE
Croup can be caused by a number of viruses including parainfluenza and influenza virus.
Signs and symptoms
Croup is characterized by a "barking" cough "), stridor, hoarseness, and difficulty breathing which usually worsens at night
Pathophysiology
The viral infection that causes croup leads to swelling of the larynx, trachea, and large bronchi due to infiltration of white blood cells
Swelling produces airway obstruction which, when significant, leads to dramatically increased work of breathing and the characteristic turbulent, noisy airflow known as stridor.

Asthma is a chronic inflammatory disorder of the lower airways. Asthma may be diagnosed any time after one year of age
Asthma is usually detected by a persistent dry cough, particularly at night, in the early morning or with exercise.
It is usually accompanied with chest tightness, shortness of breath and a wheeze.
Narrowing of the airways is caused by inflammation, extra mucous and bronchoconstriction
It has three main components that can be characterised as follows:
= A narrowing of the airway due to bronchoconstriction.
= Associated swelling in the airway and,
= Increased production of airway secretions.
The airway can become obstructed due to this response
EXTRINSIC VS INTRINSIC ASTHMA
Extrinsic (outside cause)
Classic allergic asthma resulting in bronchospasm, increased mucous secretions, and increased vascular permeability.
Common in children, young adults.
· Seasonal in nature.
· Sudden brief attacks.
· Major component is bronchospasm.
· Good bronchodilator response.
Intrinsic (inherent cause)
Non-immune mechanisms such as respiratory infections, drugs such as aspirin and beta-blockers, pollutants, emotions and exercise.
· More common in older adults.
· No immunologic cause.
· Aspirin sensitivity / nasal polyps.
· May have poor bronchodilator response.

Chronic Obstructive Pulmonary Disorder (COPD)
Definition
Chronic obstructive pulmonary disease, or COPD, is a term used to describe a set of lung diseases that cause respiratory problems, by blocking airflow and making it hard to breathe.
Diseases associated with COPD include some forms of bronchiectasis, chronic asthma, emphysema, and chronic bronchitis
The two most common types of COPD include chronic bronchitis and emphysema.
Both are characterized by damage to the lungs that prevent proper respiratory functioning.
Main clinical features include shortness of breath, wheezing and a chronic phlegmy cough.
Definition of emphysema
Permanently enlarged/over-inflated alveolar due to the destruction of the alveolar walls.
Definition of chronic bronchitis
Hypersecretion of mucous and chronic productive cough for at least 3 months of the year for at least 2 consecutive years.
Definition of Bronchiectasis
Permanent distortion and dilation of bronchi and bronchioles.
PATHOPHYSIOLOGY OF EMPHYSEMA
In patients with COPD, exposure to cigarette smoke leads to the ..............of ...............walls and the permanent ................ ................. of ............... .................... spaces.
During exposure to cigarette smoke, ................and ................(white blood cells) gather in .......................
Excessive ..................to ................and .................leads to a breakdown of ................................ in the alveolar, the .......................of ..................walls and the loss of ....................tissue.
Breakdown of ............... .................leads to:

Loss
Emphysema:
In patients with COPD, exposure to cigarette smoke leads to the destruction of alveolar walls and the permanent over inflation of alveolar air spaces.
During exposure to cigarette smoke, neutrophils and macrophages (white blood cells) gather in alveoli.
Excessive exposure to neutrophils and macrophages leads to a breakdown of elastic fibres in the alveolar, the thickening of bronchial walls and the loss of pulmonary tissue.
Breakdown of elastic fibres leads to:
= Decrease recoil within the alveoli
= Air trapping
= Lung over inflation, which results in barrel chest
Thickening of bronchial walls leads to:
= Narrowed airways
Loss of pulmonary tissue leads to:
= Decreased gas exchange
= VQ (ventilation/perfusion) mismatch
PATHOPHYSIOLOGY OF CHRONIC BRONCHITIS
Chronic Bronchitis:
Inhaled ..............(smoke) cause increase in ............presence, resulting in ................within the ..............wall.
Constant ................increases the ......... and ............... of ................cells and ................. glands.
This process leads to the ...............of ............. resulting in ................ to clear ...................
Impaired ...............function and increased ................production lead .................. .......................
Chronic Bronchitis:
Inhaled irritants (smoke) cause increase in neutrophil presence, resulting in inflammation within the bronchial wall.
Constant inflammation increases the size and number of goblet cells and mucous glands.
This process leads to the reduction of cilia resulting in inability to clear mucous.
Impaired ciliary function and increased mucous production lead narrowing airways.
PATHOPHYSIOLOGY OF BRONCHIEACTSIS
Often .................to other ..............disease or previous childhood .............. infections.
Recurrent airway ............... and ................... leads to deterioration in muscle and/or ............. fibres within ..............walls. resulting to the permanent .......................... of the bronchi and bronchioles
Widened ................ allow .................to pool.
Stagnant ..............provides excellent ............... for ....................to develop.
Bronchiectasis:
Often secondary to other respiratory disease or previous childhood chest infections.
Recurrent airway infection and inflammation leads to deterioration in muscle and/or elastic fibres within bronchial walls.
Widened bronchi allow mucous to pool.
Stagnant mucous provides excellent medium for bacteria to develop.

Dyspnoea (shortness of breath)
Chronic non-productive cough = due to .......... trapping
Wheeze
Difficulty exhaling

Peripheral Oedema
SIGNS AND SYMPTOMS OF BRONCHIEACTISIS
Dyspnoea (shortness of breath)
Chronic cough
Up to 240ml of mucous production per day
Foul breath
Haemoptysis
Frequent lung infection
COPD patients and oxygen therapy (what happens with excessive O2 administration and the relevance of the Haldane Effect)
Patients with COPD optimise gas exchange due to hypoxic vasoconstriction. During excessive O2 administration, vasodilation occurs which moves blood to inadequately ventilated areas of the lungs. This results in reduced O2 absorption and increased CO2 retention.
The Haldane Effect
= If the pressure of oxygen in the blood is high, haemoglobin will release CO2 (normal in the lungs).
= If the pressure of oxygen in the blood is low, haemoglobin will bind to CO2 (normal in the tissue).
= During over oxygenation, the release of unbound CO2 will significantly increase.
= As the pressure of CO2 in the lungs will therefore be greater than O2 (which is abnormal due vasodilation), haemoglobin will bind to CO2 with greater affinity than O2 and subsequently reduce oxygenation.
Definition of Anaphylaxis
Anaphylaxis is any acute onset of hypotension, bronchospasm or upper airway obstruction where anaphylaxis is considered possible. Even if typical skin features are not present
OR
Any acute onset illness with typical skin features (urticarial rash or erythema/flushing and/or angioedema) PLUS involvement of respiratory and/or cardiovascular and/or persistent severe gastrointestinal symptoms.
KEY TERMS: ANAPHYLAXIS and their definition
Antigen:
Antibody:
Immunoglobulin E (IgE):
Basophil:
Mast cell:
Antigen:
Substances (usually a protein) that enter your body and induce the formation of antibodies. These may sometimes referred to as allergens. A substance that is an allergen for one person may not be for another.
Antibody:
Neutralises antigens and removes them from the body.
Immunoglobulin E (IgE): Accounts for less than 1% of antibodies in normal serum. Responsible for immediate hypersensitivity reactions
Basophil:
A white blood cell that promotes inflammation
Mast cell:
Distributed amongst connective tissues (skin, lungs, GI tract which is where allergens are mostly likely to enter the body) . Filled with vasoactive amines (histamine, serotonin, leukotrienes).
Mast cells release amines as part of the inflammatory response.
They have a role in defending the body against parasites and they have receptors for IgE antibody on their surface.
This release is stimulated by antigens binding to IgE, injury (i.e. trauma) or chemical agents (e.g. toxins, or in some people, physical stresses such as exercise).
Antigens may enter your body via (4 routes)
Injection
Ingestion
Inhalation
Absorption

Anaphylaxis the most severe form of an allergic reaction. Immediate allergic reactions are due to an interaction between Immunoglobulin-E (IgE) antibodies and an antigen (allergen) with a resulting release of chemicals from cells such as basophils and mast cells.
Antigens will enter the system and trigger an immune response which leads to the production of antibodies (or immunoglobulins) which are designed to fight the invading antigens by binding to them and causing degranulation of the cell.
This degranulation will cause a release of the chemicals that will fight the invading cells, such as histamine.
· This normal antigen- antibody reaction is what protects the body from disease by activating the immune response. The immune responses are normally protective, however they can become oversensitive and become directed toward harmless antigens to which we often are exposed; this response is known as an allergic response.
Mild to moderate allergic reactions
Mild to moderate allergic reactions
These reactions do not involve the circulatory or respiratory system. They usually occur minutes to 2 hours of exposure to an allergen.
Mild to moderate symptoms:
Hives or welts
Tingling mouth
Angioedema (swelling of lips, face, eyes)
Abdominal pain (this is a sign of anaphylaxis to medications and insect stings and bites)
Vomiting (this is a sign of anaphylaxis to medications and insect stings and bites)
What is anaphylaxis and its pathophysiology?
Anaphylaxis is usually ............... progressing and is an acute .................... reaction that can affect multiple ............... systems. It is a severe life threatening event which may impact one or more of the ...................... or ................... systems.
Anaphylaxis is caused by the ................... release of .................... mediators which results in a systemic ............... in capillary ..................., ............... muscle ................... and peripheral .......................

Anaphylaxis is usually rapidly progressing and is an acute hypersensitivity reaction that can affect multiple organ systems. It is a severe life threatening event which may impact one or more of the cardiovascular or respiratory systems.
Anaphylaxis is caused by the widespread release of inflammatory mediators which results in a systemic increase in capillary permeability, smooth muscle contractility and peripheral vasodilation.
Allergic sensitisation occurs when an antigen enters the body and activates the immune system response, leading to the production of IgE antibodies directed against that antigen.
These antibodies then remain inactive on the cells until another exposure to the antigen and are referred to as antigen specific immunoglobulins.
When the antigen enters the body again, it binds to the IgE antibodies on mast cells and basophils. This interaction causes degranulation of the cell and the release of chemical mediators to fight the allergen.
These chemical mediators include:
histamines
leukotrienes
heparin
kinins
prostaglandins
thromboxanes
The physiological effects of inflammatory mediators of Anaphylaxis
An increase in the permeability of vessels
Causes dilation of capillaries and venules (causing flushing & angioedema)
Plasma leaks into interstitial space (decreases intravascular fluid volume and causes swelling)
Vasodilation further decreases cardiac preload, decreasing stroke volume and cardiac output (hypotension)
Contraction of smooth muscle in the GI tract and bronchial tree (associated with increases in gastric, nasal and lacrimal secretions and bronchospasm)
Signs and Symptoms of Anaphylaxis
Difficult/noisy breathing.
Swelling of tongue
Swelling/tightness in throat
Difficulty talking and/or hoarse voice
Wheeze or persistent cough.
Persistent dizziness and/or collapse
Change of consciousness
Hypotension
Pale and floppy (young children)

Introduction
Clinical Presentation
Smoke inhalation occurs when you breathe in harmful smoke particles and gases. Inhaling harmful smoke can inflame your lungs and airway, causing them to swell and block oxygen. This can lead to acute respiratory distress syndrome and respiratory failure.
Clinical Presentation
Altered Conscious State (note: may be delayed; may also present as changes in behaviour, neurological, or mental status.)
Cough
Shortness of breath Stridor Wheeze Hoarseness
Headache
Skin changes
Cyanosis - hypoxia
Bright red - carbon monoxide poisoning (very late sign)
Burns
Eye damage
Seizures
Soot in the nose or throat
Chest pain
