Effect of active external rewarming on esophageal temperature in simulated prehospital accidental hypothermia: a randomized crossover trial.

ABSTRACT:

Background

Prehospital rewarming is crucial to reduce mortality and improve outcomes in patients with accidental hypothermia. Although international guidelines recommend combining active external rewarming with passive rewarming, the effect of active external rewarming remains unclear. We evaluated the effects of active external rewarming compared to passive rewarming in cold-stressed, nonshivering volunteers.

Methods

This randomized, crossover field study aimed to recruit 12 participants and was performed in May/June 2024 in Lom, Norway. The participants were dressed in wet clothing and placed in a - 2 °C ice tunnel for 2 h or until their esophageal temperature reached 35 °C. Endogenous thermoregulation, most importantly shivering, was suppressed using a drug protocol. Afte
