Abstrakt: Background: Immigrants crossing the Southern U.S. border are particularly susceptible to heat illness. We review 3 patients from a heat-related mass-casualty incident with variations in heat stroke presentation, course, and outcome.
Case Report: On July 23, 2017, emergency medical services responded to a trafficking-related mass-casualty incident in San Antonio, Texas, involving 39 migrants found inside an abandoned tractor trailer without air conditioning who had been trafficked from Laredo, Texas. Three victims exhibiting heat stroke symptoms were taken to the ED of a large academic teaching hospital. Patient 1 was a 42-year-old man who presented with seizing, vomiting, and a core temperature of 38.8°C (101.8°F). His 54-day hospital course was notable for 2 cardiac arrests, disseminated intravascular coagulation, prolonged lactic acidosis, and residual kidney disease. Patient 2 was a 32-year-old man who presented to the emergency department intubated in the field with a core temperature of 40.7°C (105.3°F). His 60-day hospital course was notable for disseminated intravascular coagulation, severely elevated troponin, prolonged lactic acidosis, and stroke. Patient 3 was a 20-year-old man who presented with seizing and decorticate posturing, with a core temperature of 40.5°C (104.9°F). His 6-day hospital course was notable for rapid clinical improvement and full recovery. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Emergency physicians will encounter heat stroke victims. Our patients were exposed to an identical environment, and while each patient was otherwise healthy and differed significantly only in age, they exhibited a diversity of heat stroke presentations and sequelae. Treatment prioritizes cooling, but rapid deterioration requires intensive treatment of multiorgan failure.
