C11 MSN M5 UB Haemorrhage- shock
Introduction to Haemorrhage
Haemorrhage is a significant medical emergency requiring early detection and intervention.
Impedes blood flow to vital organs, reducing oxygen supply.
Nurses must be skilled in identifying and managing haemorrhage.
Definition of Haemorrhage
Loss of blood from blood vessels due to trauma or disorder.
Can be either internal (inside the body) or external (on the surface).
May originate from arteries, veins, or capillaries.
Types of External Bleeding
Capillary Bleeding
Slow and oozing.
Easily controlled and often stops spontaneously.
Venous Bleeding
Steady flow; easier to control than arterial bleeding.
Occurs in a low-pressure system.
Arterial Bleeding
Rapid and profuse with spurting corresponding to heartbeats.
Most difficult to control due to high pressure.
Causes of Haemorrhage
Physical injury.
Low platelet count.
Complications from pregnancy (threatened abortion).
Piles (hemorrhoids).
Surgical complications.
Organ diseases (liver disease, brain trauma).
Acute bronchitis and menstrual problems.
Types of Haemorrhage
Postoperative Haemorrhage
Can originate from arteries (arterial), veins (venous), or capillaries (capillary).
Other Types
Reactionary Haemorrhage: Delayed bleeding post-injury.
Postpartum Haemorrhage: Bleeding after childbirth.
Secondary Haemorrhage: Delay post-infection or injury.
Hematuria: Bleeding in urine.
Hemoptysis: Coughing up blood.
Hematemesis: Vomiting blood.
Classification of Haemorrhage
Primary Haemorrhage
Occurs immediately after injury or surgery.
Secondary Haemorrhage
Develops 7-14 days post-injury, can be due to infection or malignancy.
Sub-classifications of Haemorrhage
Internal Haemorrhage
Blood loss inside the body, observable through urine, stools, or respiratory secretions.
External Haemorrhage
Visible bleeding resulting from an injury or internal bleeding that becomes visible.
Classification According to Volume Loss
Class I Haemorrhage
Up to 15% blood volume; no vital sign changes, no resuscitation needed.
Class II Haemorrhage
15-30% blood volume; tachycardia may occur and slight blood pressure changes.
Volume resuscitation recommended but no blood transfusion required.
Class III Haemorrhage
30-40% blood volume loss; significant drop in blood pressure and increased heart rate.
Requires fluid resuscitation and possible blood transfusion.
Class IV Haemorrhage
Loss of >40% blood volume; high risk of death without aggressive intervention.
Shock (Hypovolaemic Shock)
Definition: Inadequate blood volume to fill the vascular space.
Types of blood volume loss:
Absolute: From haemorrhage, gastro intestinal loss, etc.
Relative: Fluid shifts into extravascular space, e.g., during sepsis.
Clinical Features of Hypovolaemic Shock
Symptoms include pallor, thirst, cyanosis, tachycardia, cold clammy skin, hypotension, oliguria.
Specific symptoms may vary based on the cause.
Assessing Patient for Haemorrhage
Conduct primary and secondary assessments, noting signs of bleeding.
Areas to assess include: thorax, abdomen, retroperitoneum, pelvis, and thighs.
Aims in Managing Hypovolaemic Shock
Objectives include stopping fluid loss and restoring circulating volume.
General guidance includes a 3:1 resuscitation ratio (3ml crystalloid for every 1ml blood loss).
Administer oxygen and address the underlying cause.
Immediate Nursing Care
Vital signs monitoring every 15 minutes until stable, then hourly.
Continuous assessment of pain severity and temperature.
Monitor hemodynamic findings, ABGs, and urine output (indicative of kidney perfusion).
Establish and maintain IV access for medication and fluid administration.
Tools for Managing Haemorrhage
Focus on medications, teamwork, collaboration, surgical interventions, and follow-up monitoring.
Post-Management Monitoring
Check vital signs, circulation, and monitor urine output closely.
Maintain warm environment to prevent vasoconstriction due to temperature drop.
Complications of Haemorrhage
Severe blood loss can lead to organ failure, seizures, coma, or death.
Prolonged oxygen deprivation can cause brain tissue infarction.
Introduction to Haemorrhage
Haemorrhage is a significant medical emergency requiring early detection and intervention due to the critical need for maintaining blood flow to vital organs. This condition can swiftly lead to a state of shock if not addressed promptly, thereby reducing oxygen supply to the body's tissues. Nurses and healthcare professionals must be highly skilled and knowledgeable in identifying the signs of haemorrhage and managing its consequences to ensure patient safety and optimal outcomes.
Definition of Haemorrhage
Haemorrhage is the loss of blood from blood vessels, which can occur due to various causes, including trauma, disorders, or diseases affecting the vascular system. It can be classified as either internal, where blood escapes into body cavities or tissues, or external, where blood loss occurs at the surface of the body. The source of bleeding may originate from arteries, veins, or capillaries, each characterized by different flow dynamics and management approaches.
Types of External Bleeding
Capillary Bleeding: Characterized by slow, oozing blood that is easily controlled. This type typically stops spontaneously due to the minor nature of the injury.
Venous Bleeding: This involves a steady flow of blood and occurs in a low-pressure system, making it easier to control than arterial bleeding. Interventions often include direct pressure to the wound.
Arterial Bleeding: Marked by rapid and profuse bleeding that spurts in rhythm with the heartbeat. It is more challenging to control due to the high pressure within arterial blood vessels and may require advanced measures such as tourniquets or surgical intervention.
Causes of Haemorrhage
Physical Injury: Trauma from accidents, falls, or surgical procedures.
Low Platelet Count: Conditions like thrombocytopenia can predispose individuals to bleeding tendencies.
Complications from Pregnancy: Conditions such as placental abruption can lead to life-threatening situations.
Piles (Hemorrhoids): Discomfort and bleeding associated with swollen veins in the rectal area.
Surgical Complications: Bleeding that may occur post-operatively requiring monitoring and intervention.
Organ Diseases: Conditions such as liver disease that affect clotting factors, increasing bleeding risks.
Acute Bronchitis and Menstrual Issues: Both conditions may result in increased blood loss due to inflammation and vascular changes.
Types of Haemorrhage
Postoperative Haemorrhage: Can originate from arteries, veins, or capillaries, warranting close observation.
Reactionary Haemorrhage: Delayed bleeding after an initial injury or surgical intervention, often requiring additional treatment.
Postpartum Haemorrhage: Severe bleeding following childbirth, necessitating prompt medical response to prevent morbidity and mortality.
Secondary Haemorrhage: Occurs typically days to weeks post-injury or surgery, possibly related to infection or malignancy.
Hematuria: Blood present in urine, indicating potential internal bleeding.
Hemoptysis: The act of coughing up blood, warranting immediate evaluation for causes such as infection or malignancy.
Hematemesis: Vomiting of blood, often indicative of upper gastrointestinal bleeding.
Classification of Haemorrhage
Primary Haemorrhage: This occurs immediately after an injury or surgery, demanding urgent assessment and intervention.
Secondary Haemorrhage: Develops in the days or weeks following an injury, often due to complications like infections or underlying pathology.
Sub-classifications of Haemorrhage
Internal Haemorrhage: Involves blood loss inside the body, which may be detected through urine, stools, or signs of respiratory distress.
External Haemorrhage: Visible bleeding due to injury or an internal source that manifests outwardly.
Classification According to Volume Loss
Class I Haemorrhage: Involves up to 15% blood volume loss; generally no vital sign changes, and no immediate resuscitation is necessary.
Class II Haemorrhage: Engages 15-30% blood volume; signs may include tachycardia and slight changes in blood pressure. Volume resuscitation is recommended, although blood transfusion may not yet be required.
Class III Haemorrhage: Represents a loss of 30-40% blood volume; significant hemodynamic changes such as hypotension and increased heart rate are common, requiring aggressive fluid resuscitation and potential transfusion.
Class IV Haemorrhage: Exceeds 40% blood volume loss; poses a high risk of morbidity and mortality without immediate intervention, as the patient may enter hypovolaemic shock.
Shock (Hypovolaemic Shock) Definition
Inadequate blood volume to fill the vascular space leads to shock. It can be categorized based on how blood volume loss occurs:
Absolute: Direct loss due to haemorrhage or gastrointestinal fluid loss.
Relative: Occurs due to fluid shifts, such as in sepsis, where intravascular volume is depleted without external loss.
Clinical Features of Hypovolaemic Shock
Common symptoms include pallor, excessive thirst, cyanosis, tachycardia, cold and clammy skin, hypotension, and oliguria. Specific manifestations may vary based on underlying causes and patient factors.
Assessing Patient for Haemorrhage
A thorough patient assessment includes conducting primary and secondary evaluations, concentrating on signs of bleeding, which necessitates a focused examination of the thorax, abdomen, pelvis, retroperitoneum, and thighs.
Aims in Managing Hypovolaemic Shock
Key objectives include stopping ongoing blood loss, protecting the function of remaining circulation, and restoring blood volume. General guidelines recommend a 3:1 resuscitation ratio (3 ml of crystalloid fluids for every 1 ml of blood loss).
Immediate Nursing Care
Vital signs monitoring should be performed every 15 minutes until the condition stabilizes, at which point it can shift to hourly assessments. Continuous evaluation includes tracking pain severity, temperature, hemodynamic parameters, arterial blood gases (ABGs), and urine output, which serves as an important indicator of kidney perfusion. Establishing and maintaining intravenous access is crucial for fluid and medication administration.
Tools for Managing Haemorrhage
Effective management employs a combination of medications, collaborative teamwork, surgical interventions, and vigilant follow-up monitoring to ensure comprehensive patient care and recovery.
Post-Management Monitoring
Post-intervention, healthcare providers should diligently check vital signs, circulation, and urine output while ensuring the patient is in a warm environment to prevent vasoconstriction stemming from a drop in body temperature.
Complications of Haemorrhage
Severe blood loss carries risks for complications including organ failure, seizures, coma, and ultimately death. Extended periods of inadequate oxygen can lead to brain tissue infarction, manifesting serious long-term consequences.
