Clinical Deterioration, Escalation Protocols, Sepsis Pathway, and Pediatric Medication Dosing
Escalation and Trajectory of Illness
In patient care, people are admitted for an underlying reason (illness or post-surgery) and require continual reassessment. Illnesses often follow a trajectory with predictable phases.
Common trajectory: symptoms develop, patient feels very unwell for a few days, then should begin to improve and return to baseline.
Some patients improve with initial treatment (antibiotics, fluids, analgesia) but then deterioration occurs unexpectedly; recognizing this early is crucial to intervene appropriately.
Purpose of escalation: prevent adverse outcomes and reduce the need for extreme life-saving interventions by intervening early.
Ward environment can obscure deterioration due to busyness, poor documentation, or slow trend recognition; scribbled or illegible notes can mask a worsening trajectory.
Children are adept at compensating physiologically, masking deterioration until decompensation occurs; early signs can be subtle (e.g., sluggish capillary refill). Compensation can sustain perfusion to core organs at the expense of peripheral tissues.
Decompensation timeline in kids: they may appear reasonably well for a period, then rapidly deteriorate after some hours (the bedside pattern clinicians watch for).
Key aim: recognize early signs and intervene to avoid reaching critical states, thereby reducing both risk and the volume/intensity of interventions required.
Compensatory Mechanisms and Pediatric Physiology
Compensation example: hypovolemia from dehydration or sepsis triggers vasoconstriction to preserve perfusion to heart, brain, kidneys, and liver.
Signs of compensation: sluggish capillary refill, cool peripheries, and preserved blood pressure for a time.
Compensation has limits; children are experts at masking illness but will eventually decompensate when energy stores are exhausted.
Pediatric trajectory: early subtle signs precede overt deterioration; vigilant monitoring is essential to catch deterioration before sharp declines.
The Escalation System and Paracharts
Paracharts: five age-specific charts used to track vital signs and escalation triggers; use the correct chart for the child’s age.
The charts guide timely escalation as trends emerge, reducing delays and misdocumentation.
Early Warning Scores (EWS) and sepsis pathway are integrated in the WA system to prompt the appropriate clinical response.
Clean, consistent documentation and quick access to trends are essential to avoid missing deterioration.
Structured Communication: ISBAR and Team-Based Care
Healthcare is a team sport: when a patient deteriorates, seek help early from the most senior person available.
Use structured communication to convey essential context: ISBAR (Identify, Situation, Background, Assessment, Recommendation).
Clear articulation of background (admission, recent procedures, current trajectory) helps the team assess urgency and plan.
If unsure or if parents are concerned, escalate to senior ward staff; validated concerns from families are important signal to reassess.
Clear, concise, non-rambling communication reduces delays and errors.
The Early Warning Score (EWS) and Sepsis Pathway Overview
The Early Warning Score (EWS) triggers escalation based on abnormal vital signs and clinical picture; the current chart in WA integrates with a sepsis pathway.
Sepsis is a systemic infection, not just fever; it requires abnormal vital signs plus one or more infection-related criteria.
Fever alone is not sepsis; systemic involvement may present with tachycardia, delayed capillary refill, mottled skin, drowsiness, or non-blanching rash.
Important to interpret the full clinical picture (vital signs, perfusion, mental status) rather than relying on a single sign.
As the EWS rises (more abnormal signs or higher severity), escalation to more senior clinicians occurs more quickly.
For severe abnormality (e.g., EWS 6–7 or higher), urgent senior medical review is indicated, often within 15 minutes.
If sepsis is suspected, look for additional criteria and prompts to activate the sepsis pathway.
Sepsis Pathway: What It Is and Why It Matters
Sepsis pathway flow: recognize deterioration → obtain a focused assessment → involve medical colleagues → confirm sepsis suspicion → initiate treatment pathway.
Abnormal vital signs plus potential infection trigger activation of the sepsis pathway for prompt management.
Systemic effects of sepsis: decreased intravascular volume due to capillary leakage, hypoperfusion, organ dysfunction (liver, kidneys, gut), and potential progression to multi-organ failure.
Early antibiotics and aggressive resuscitation are critical to improve outcomes.
Sepsis Pathway: Assessment, Tests, and Empiric Therapy
Initial assessment focuses on looking for focal sources of infection (abdomen, meningitis signs like neck stiffness, photophobia) and disruptive findings (wounds, indwelling devices).
Early antibiotics and resuscitation decisions are based on clinical suspicion and the trajectory, not waiting for perfect diagnostic certainty.
Investigations (before results come back):
Blood cultures
Kidney and liver function tests (LFTs)
CRP, lactate
Full blood count (to assess white cell response)
Additional samples as indicated (urine, CSF via lumbar puncture in young infants with fever of unknown origin; nasal/throat swabs, stool cultures, wound swabs, etc.)
Empirical therapy in pediatrics often includes broad-spectrum antibiotics and antiviral coverage when meningitis is a concern:
Amoxicillin with clavulanic acid (co-amoxiclav) and ceftriaxone as beta-lactam coverage
Acyclovir for potential viral meningitis
Fluids and supportive care as part of resuscitation
In neonates/infants with fever of unknown origin, treatment often begins before culture results are back due to rapid deterioration risk.
Reassess and adjust therapy as results return; antibiotic choice and duration guided by cultures and clinical response.
Practical Pharmacology: Monographs and Pediatric Dosing
Monographs provide pediatric-specific dosing, reconstitution, dilution, and administration instructions for each antibiotic.
In pediatrics, dosing is weight-based; doses are calculated per kilogram and then converted to volume for administration based on concentration.
Key concept: reconstitution and dilution are essential for accurate dosing in children because doses vary by weight and concentration differs by vial.
Example: Amoxicillin/clavulanic acid monograph
Powder: 1000 mg
Reconstitute with 19.1 mL of water for injection to yield a total volume of 20 mL
Resulting concentration: rac{1000 ext{ mg}}{20 ext{ mL}} = 50 rac{ ext{mg}}{ ext{mL}}
Powder volume (before reconstitution) is 0.9 mL, but after reconstitution, the entire 20 mL becomes the solution used for dosing.
For a target dose of 250 mg: volume needed = rac{250 ext{ mg}}{50 rac{ ext{mg}}{ ext{mL}}} = 5 ext{ mL}
Dosing rules in pediatrics are weight-based: e.g., ext{Dose per dose} = ext{Weight (kg)} imes 25 rac{ ext{mg}}{ ext{kg}}; common dosing frequency examples include every 8 or 12 hours depending on the regimen.
For a given patient, steps to calculate dose:
Find the patient’s weight on the medication chart
Look up the dosing regime in the monograph (mg/kg and frequency)
Compute the dose in mg: ext{Dose}{ ext{mg}} = ext{Weight}{ ext{kg}} imes ext{Dose}_{ ext{mg/kg}}
Convert the dose to volume using the stock concentration: ext{Volume (mL)} = rac{ ext{Dose}{ ext{mg}}}{ ext{Concentration}{ ext{mg/mL}}}
Important caution: always calculate the dose yourself prior to administration; do not rely solely on someone else’s calculation.
Worked Dosing Practice (Illustrative Calculations)
Example 1: Amoxicillin clavulanate dose = { ext{Weight}} imes 25 rac{ ext{mg}}{ ext{kg}} per dose; if patient weighs 3.5 kg and is prescribed 25 mg/kg, then per-dose dose is:
3.5 ext{ kg} imes 25 rac{ ext{mg}}{ ext{kg}} = 87.5 ext{ mg per dose}
If the concentration is 50 rac{ ext{mg}}{ ext{mL}}, then volume per dose = rac{87.5 ext{ mg}}{50 rac{ ext{mg}}{ ext{mL}}} = 1.75 ext{ mL}
Example 2: If dosing every 12 hours (twice daily) and body weight is 3.5 kg, daily total dose = 87.5 ext{ mg} imes 2 = 175 ext{ mg} and daily volume = rac{175 ext{ mg}}{50 rac{ ext{mg}}{ ext{mL}}} = 3.5 ext{ mL}
Example 3: A neonate example (10 days old, 3.5 kg) using the same weight-based rule: daily dose = 3.5 ext{ kg} imes 25 rac{ ext{mg}}{ ext{kg}} imes 2 ext{ doses/day} = 175 ext{ mg/day}; per-dose = 87.5 ext{ mg}
ightarrow ext{volume } = 1.75 ext{ mL per dose}Real-world reminders:
Use the weight to determine dose first, then convert to volume.
Confirm volume on reconstitution and ensure the correct route (IV infusion vs IV push) per monograph.
Document accurately and verify calculation aloud when administering.
Distraction Therapy and Pediatric Procedural Comfort
Fundamental idea: you cannot remove all pain, but you can minimize distress and perceived pain through distraction, environment, and child-centered communication.
Why distraction matters: reduces anxiety, decreases autonomic responses (heart rate, BP), and improves cooperation during procedures.
For complex, recurrent pediatric patients (e.g., cystic fibrosis tune-ups), trauma from repeated procedures can shape future care if not addressed.
Core strategies for distraction:
Use age-appropriate toys and activities (older tech like tablets may lack novelty; older “old-school” toys can captivate a child who has never seen them before).
Use conversation and storytelling; engage with pets or dolphins as topics during preparation.
Guided imagery for older children; help them imagine being somewhere else during the procedure.
Allow developmentally appropriate decisions (e.g., where to sit, which toy to hold, or whether to watch the procedure).
Involve parents: if parents are calm, their presence helps the child stay calm.
Use eye-level communication; avoid standing over the child; ensure the bed is positioned so the child won’t fall; explain steps clearly and honestly.
Practical examples:
The “Craig” technique: an experienced pediatric anesthetist used a magic trick with a coloring book to distract during inhalational induction, then gradually guided the child to sleep; combined with supportive nursing actions (finding a vein, applying local anesthetic, etc.).
Distraction during painful steps (e.g., suturing, injections) helps reduce the child’s perception of pain and distress.
Honest communication with kids: tailor language to developmental level; avoid promises that might not be kept (e.g., “this won’t hurt”) if it will; explain why procedures are necessary and how they help.
Real-world considerations:
Some children will participate actively in their care (watching procedures, handling equipment); others prefer not to know details; adapt accordingly.
Height and positioning matter: standing over a child can be intimidating; align eye level and maintain a sense of safety.
Psychological and Ethical Considerations in Pediatric Care
Building trust between child and caregivers is essential; breaking trust can have lasting negative effects on future care.
Involve parents but validate their concerns; if parents are not satisfied with assessments, escalation to senior staff and hospital management may be required.
Ethical balance: do not delay necessary intervention due to fear of triggering distress; however, minimize harm by using distraction and gentle techniques.
The goal is to reduce trauma and avoid escalating to intensive care unless absolutely necessary.
Monographs and Practical Methods for Medication Preparation
Monographs are hospital-specific, detailing dosing, reconstitution, concentration, and administration for pediatric patients.
Steps to prepare pediatric IV antibiotics:
Locate the weight on the patient’s medication chart to determine dosing.
Refer to the hospital’s monograph for the dosing regime and reconstitution instructions.
Reconstitute the powder with the specified volume of diluent (e.g., 19.1 mL water for 1000 mg powder to yield 20 mL solution).
Calculate resulting concentration: ext{Concentration} = rac{ ext{Total amount (mg)}}{ ext{Total volume (mL)}}
Determine the dose in mg and convert to the volume to administer using the concentration: ext{Volume} = rac{ ext{Dose (mg)}}{ ext{Concentration} ext{(mg/mL)}}
Emphasize two critical points:
Weight-based dosing is essential in pediatrics; a dose for an adult cannot be simply scaled down.
Do not skip reconstitution/dilution steps; the exact volumes and concentrations are critical for accurate dosing.
Practical tip: in the hospital setting, there is often a folder of monographs for all antibiotics; always use the patient-specific monograph rather than a generic guide.
Final Practical Takeaways
Recognize deterioration early: use a full-system assessment (ABC-DEF/ABCD) and escalate with ISBAR to the right level of care.
Early aggressive management of sepsis saves lives; treat promptly with antibiotics and resuscitation, guided by blood tests and clinical signs.
Dosing in pediatrics is weight-based and requires careful reconstitution, dilution, and calculation to ensure accuracy.
Distraction therapy and gentle, developmentally appropriate communication reduce procedural distress and trauma for pediatric patients.
Always document observations clearly, monitor trends, and escalate when signs indicate potential deterioration.
Remember: you are not blamed for calling for help too early; you’re blamed for not responding when deterioration is evident. Be vigilant, proactive, and collaborative.
