    Study Notes

    Healthy Work Environment

    • Essential for effective critical care delivery.

    Primary Survey (ABCDE)

    • Framework for rapid assessment: Airway, Breathing, Circulation, Disability, Exposure.
    • In cases of excessive bleeding, prioritize CAB (Circulation, Airway, Breathing) to halt active bleeding.
    • For trauma, establish two large bore IV accesses (antecubital or above).

    Secondary Survey and Resuscitation Interventions

    • Conduct comprehensive head-to-toe assessment after addressing immediate life threats to identify additional injuries.

    Airway Management

    • Spontaneous Breathing: Provide non-rebreather mask.
    • Ventilatory Support: Use bag valve mask with an appropriate airway and 100% oxygen.
    • Significant impairment requires endotracheal intubation and mechanical ventilation.

    Triage Categories

    • Emergent: Immediate life or limb threat (e.g., chest pain).
    • Urgent: Requires quick treatment but not life-threatening (e.g., abdominal pain).
    • Nonurgent: Can wait 7 hours for care without significant risks (e.g., strains, sprains).

    Glasgow Coma Scale (GCS)

    • Eye Opening Response (max 4): Spontaneous (4), Speech (3), Pain (2), No Response (1).
    • Best Verbal Response (max 5): Oriented x 3 (5), Confused (4), Inappropriate Words (3), Incomprehensible Sounds (2), No Response (1).
    • Best Motor Response (max 6): Obeys commands (6), Moves to localized pain (5), Flexion to pain (4), Decorticate response (3), Decerebrate response (2), No Response (1).
    • Total GCS Score: 15 (best response), 8 or less (comatose), 3 (totally unresponsive).

    Heat Exhaustion

    • Results from dehydration due to heavy perspiration and inadequate fluid/electrolyte intake.
    • Symptoms: Weakness, nausea, vomiting, headache, normal body temperature, hyponatremia.
    • Untreated can progress to heat stroke.

    Heat Stroke

    • Medical emergency with potential fatality if untreated.
    • Body temperature may exceed 104°F (40°C).
    • Types:
      • Exertional: Rapid onset from strenuous activity in hot, humid conditions.
      • Classical (non-exertional): Develops gradually from prolonged heat exposure.
    • Assessment includes history of heat exposure, elevated temperature, altered mental status, hypotension, tachycardia, oliguria, elevated cardiac troponin, and electrolyte imbalances.
    • Treatment involves emergency care, restoring thermoregulation, and following ABCDE protocol.

    Anaphylaxis from Arthropods and Bees

    • Symptoms include local reactions (swelling, urticaria), bronchospasm, laryngeal edema, hypotension, nausea, vomiting, and potential renal failure.
    • Monitor vital signs and cardiac function.
    • Administer medications: antihistamines, epinephrine, albuterol, corticosteroids.
    • Observe patients for 7 hours or consider admission.

    Snakebites

    • Significant risk of airway compromise and respiratory failure.
    • Ensure a patent IV line and have resuscitation equipment ready.
    • Consult Poison Control for antivenin guidance.

    Lightning Injuries

    • Highly preventable; can lead to varying effects:
      • Mild: Stunned or confused.
      • Moderate: Confusion or comatose, temporary paralysis.
      • Severe: Profound cardiac/CNS effects, potential cardiac arrest.
    • Assess for complications like cataracts, tympanic membrane rupture, cerebral hemorrhage, depression, PTSD, and Lichtenberg figures.
    • Monitor for hypovolemia and shock; may require ventilation.
