Study Notes
Environmental Emergencies
-
Heat Cramps: Severe muscle cramps in large muscle groups due to heavy work, and inadequate fluid/salt intake. Symptoms include intense pain, nausea, tachycardia, pallor, weakness, and diaphoresis. Treatment involves rest and oral/parenteral sodium and water replacement. Prevention includes avoiding exercise for 12 hours and increasing fluid/salt intake.
-
Heat Exhaustion: Prolonged heat exposure over hours or days. Symptoms include fatigue, nausea/vomiting, extreme thirst, feelings of anxiety, hypotension, tachycardia, elevated body temperature (mild to severe ranging from 99.6 to 105.8 degrees Fahrenheit), dilated pupils, mild confusion, ashen color, and profuse diaphoresis. Treatment involves correlating fluid replacement with clinical/lab findings. Hospital admission may be necessary for older adults, chronically ill patients, or those who do not improve in 3-4 hours.
-
Heatstroke: A medical emergency. Results from failure of hypothalamic thermoregulatory processes. Increased sweating, vasodilation, and increased respiratory rate deplete fluids and electrolytes (especially sodium - normal range 135-145). Symptoms include, sweat gland dysfunction, core temperature rises within 10-15 minutes to over 105.8°F (41°C), altered mental status, confusion, coma, hypotension, tachycardia, tachypnea, weakness, hot and dry skin, and cessation of perspiration. Treatment involves rapidly decreasing core temperature to save brain and organs through measures like removing clothing, covering with wet sheets, fanning, and immersion in cool water.
Frostbite
-
Description: True tissue freezing, forming ice crystals in tissues and cells. Commonly affects exposed extremities like toes, fingers, tip of nose. Symptoms include initial pain followed by numbness, pallor, and coolness of the affected area(s).
-
Treatment: Rewarming. For superficial frostbite, immersion in a controlled temperature range of 98.6 to 104 degrees F circulating water is used. Deep frostbite often requires more extensive management within a medical facility, possibly including amputation depending on the severity of the damage.
Hypothermia
-
Description: Core body temperature below 95°F. Body heat production cannot compensate for heat loss to the environment. Systemic side effects are observed in contrast to frostbite, where effects are localized.
-
Risk factors: Wet clothing (increases evaporative heat loss 5x to 25x) and cold water immersion. Near-drowning.
-
Symptoms: Mild hypothermia: (93 to 95°F) and moderate hypothermia: (86 to 95°F). Severe hypothermia: (<86°F). Key symptoms include cardiovascular changes (dysrhythmias, bradycardia, hypotension), altered mental status, hypoventilation, and cold, pale, and sometimes bluish skin.
Drowning
-
Description: Respiratory impairment after submersion in water or other fluids.
-
Submersion in cold water (below 32°F [0°C]): May slow the progression of hypoxic brain injury.
-
Aspiration of fresh water: Absorbed into the circulatory system causing osmotic imbalances in the body. May be contaminated: chlorine, mud, debris, parasites & algae, potentially leading to chemical pneumonitis or bacterial pneumonia.
-
Aspiration of salt water: Draws protein-rich fluid from circulation into alveoli, leading to earlier and more pronounced pulmonary edema and impairing gaseous exchange. Hypertonic saltwater draws fluid from the vascular space into alveoli worsening respiratory issues and hypoxia, therefore potentially worsening to cerebral injury, edema, and brain death.
