Research output: Contribution to journalArticlepeer-review


Non-exertional heat stroke is defined as exposure to high outdoor temperatures, core body temperature >40 °C, and alteration of mentation. Early identification and treatment are imperative to reduce morbidity and mortality in these patients. Cold water immersion therapy is the most efficient and efficacious modality in treating heat stroke, yet it is rarely initiated in the prehospital setting. We outline a case of an 82-year-old man found unconscious outside during a regional heat wave with a temperature >107 °F. He was treated with cold water immersion using a body bag in the back of the ambulance and cooled to 104.1 °F during transport. During the 9-minute transport, the patient regained consciousness, followed basic commands, and answered basic questions. This case highlights the novel use of body bag cold water immersion as early initiation of treatment for heat stroke patients.
