A 34-year-old male arrives at the emergency department following a high-speed motor vehicle collision. He is hypotensive, has a core temperature of 35°C (95°F), and displays signs of coagulopathy with prolonged bleeding times. What are the most likely components contributing to his hemodynamic instability?
Hyperthermia, lactic acidosis, and thrombocytopenia
Hypothermia, hyperkalemia, and hypoglycemia
Hypothermia, acidosis, and coagulopathies
Hyperthermia, metabolic alkalosis, and hypercalcemia
The trauma triad of death consists of hypothermia, acidosis, and coagulopathies. Hypothermia can be caused by environmental exposure or shock, and it impairs the clotting cascade, leading to coagulopathies. Acidosis, commonly a result of poor tissue perfusion and hypoxia, further exacerbates coagulopathies and reduces cardiac function. Recognizing these interconnected factors is essential in managing severely injured trauma patients.
