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.
