Study Notes
Heat Stroke
- Pathophysiology: Failure of the body's heat-regulating mechanisms
- Signs and Symptoms (S/s): Confusion, altered mental status, hot dry skin, cerebral edema (leading to seizures, delirium, or coma), anhidrosis (lack of sweating)
- Management: IV fluids, cooling (slowly to <102°F within 1 hour), remove clothing, ice packs, cooling blankets, continuous temperature monitoring, strict I&O (input and output), 12-lead EKG, monitor cardiac rhythm, and frequent LOC and vital sign assessment. Na+ and K+ replacement due to hyponatremia and hypokalemia.
- Priority Interventions: ABCs (airway, breathing, circulation) first, remove clothing, apply cooling measures, potentially cold IV fluids.
Frostbite
- Pathophysiology: Tissue freezing from exposure to extreme cold, affecting both intracellular and extracellular fluids.
- Signs and Symptoms (S/s): Frozen extremities (hands, feet, nose, ears, cheeks) appear hard, cold, and insensitive to touch, often white or mottled blue-white.
- Risk Factors (RF): Occupational or recreational exposure to cold (e.g., skiing), homelessness, certain medical conditions (mental health disorders), alcoholism, or smoking, impaired mobility.
- Management: Avoid hot water, massage, or placing wet gauze on affected area. Remove restrictive clothing/jewelry. Electrolyte monitoring, potassium levels, educate patients on vasoconstrictors (caffeine, alcohol, tobacco). Controlled and rapid rewarming is instituted. Hourly active motion and elevation to reduce swelling. Pain management.
Poison Ingestion
- Syrup of Ipecac: No longer used due to aspiration risk, especially for corrosive poisons.
- Treatment: Dilute corrosive agents with milk or water. Gastric lavage, Activated charcoal, cathartics are rarely indicated for corrosive poisons. Monitor VS, F/E, CVP Monitor.
- Clinical Manifestations: Oral pain, vomiting, ulceration, drooling, abdominal pain, and dysphagia.
Anthrax
- Transmission: Can spread through skin contact, ingestion, or inhalation.
- Precautions: Standard precautions, as it does not spread from person-to-person. Avoid aerosolizing, care in handling contaminated materials.
- Treatment: Ciprofloxacin, Levofloxacin, Penicillin, or Doxycycline for 60 days.
Triage
- Purpose: Determine severity of illness to prioritize treatment in large-scale emergencies.
- Categorization: Levels 1 (most urgent/resuscitation), 2(urgent), 3(urgent [not immediately dying]), 4(non-urgent), and 5(minor/fast-track). Categorized based on the need for intervention.
Snake Bites
- Clinical Manifestations: Swelling, edema, echymosis (bruising), hemorrhagic bulla (blisters), necrosis (tissue death) at the site of envenomization.
- Treatment: Remove constrictive items, clean the wound, apply a light sterile dressing, immobilize below the heart. Tetanus and analgesics may be required. Labs (CBC, UA, coagulation studies) and monitoring.
Other (general):
- Compartment Syndrome: Measure extremity circumference every 30-60 minutes for 48 hours to monitor for compartment syndrome in suspected injuries.
