    Study Notes

    Seriously Ill Patient Assessment

    • Aim: Identify physiological abnormalities, determine appropriate correction methods, and diagnose the underlying cause.
    • Urgent Process: Treatment initiation often precedes a full history, detailed examination, and extensive investigations due to the urgency of the situation.
    • Parallel Tasks: History taking, examination, and initial resuscitation frequently occur concurrently.
    • Initial Focus: Prioritize essential information for guiding immediate treatment decisions, with the remaining details filled in later.
    • Re-Assessment: Regularly reassess the working diagnosis based on new information and the patient's response to treatment.

    Warning Signs of a Severely Ill Patient

    • Blood Pressure: Systolic blood pressure under 90 mmHg.
    • Pulse: Greater than 100 beats per minute.
    • Respiratory Rate: Over 20 breaths per minute.
    • Temperature: Above 38 degrees Celsius or below 36 degrees Celsius.
    • Mental Status: Confusion or disorientation.
    • Oxygen Saturation: Less than 90% on room air.
    • Urine Output: Less than 0.5 ml/kg/hour.

    Massive Blood Transfusion

    • Definition: Replacement of 50% of total blood volume (TBV) within 3 hours.
    • Threshold for Concern: Transfusion of more than 4 units of packed red blood cells (PRBCs) within 1 hour, suggesting a potential need for further transfusion.
    • Complications of Massive Transfusion:
      • Coagulopathy
      • Hypothermia
      • Citrate Toxicity
      • Acid-Base Imbalance
      • High Serum Potassium Concentration

    Blood Storage Effects

    • Increased Acidity: Blood becomes more acidic during storage.
    • Elevated Plasma Potassium: Plasma potassium levels increase with storage.
    • Decreased Platelet Function: Platelet function diminishes during storage.
    • Reduced Factor VIII Levels: Factor VIII levels decrease.
    • Plasma Calcium Levels: Plasma calcium levels do not rise during storage.

    Acute Hemolytic Reaction

    • Timeframe: Occurs within hours after transfusion.
    • Severity: More severe than delayed hemolytic reactions.
    • Cause: ABO incompatibility.
    • Management: Requires immediate supportive treatment.
    • Mechanism: Acute intravascular hemolysis.
    • Presentation: Acute hypoxia and noncardiac pulmonary edema.
    • Timeframe: Develops within 6 hours of blood product transfusion.
    • Product: Can occur with any blood component transfusion.
    • Management: Similar to acute respiratory distress syndrome.
    • Resolution: May resolve within a few days with supportive therapy.

    Management of Hemolytic Reaction

    • Immediate Action: Stop the transfusion immediately and notify the blood bank.
    • Blood Samples: Obtain blood samples for plasma hemoglobin assessment and repeat compatibility testing.
    • Urinary Catheter: Insert a urinary catheter to monitor urine output.
    • Urine Analysis: Examine urine for albumin presence.
    • Osmotic Diuresis: Initiate osmotic diuresis with mannitol and intravenous fluids.

    Plasma Transfusion Indications

    • Elevated INR: International normalized ratio (INR) greater than 1.5.
    • Invasive Procedures or Surgery: Anticipated invasive procedures or surgeries.
    • Massive Hemorrhage: Hemorrhage exceeding one blood volume.
    • Muscle Relaxant Reversal: Emergent reversal of muscle relaxant drug effects.
    • Factor Deficiences: Treatment of isolated factor deficiencies.

    Red Blood Cell Transfusion Guidelines

    • Hemodynamic Instability: Consider transfusion for ongoing, unresponsive bleeding associated with hemodynamic instability.
    • Hemodynamically Stable ICU Patients: Transfusion may be indicated for ICU patients with hemoglobin levels below 7 g/dL.
