Comparing two different methods for wrapping cold and wet patients - A human crossover field study

Abstract

Accidental hypothermia increases mortality and morbidity in trauma patients. Various methods for wrapping hypothermic patients are used worldwide. The aim of this study was to compare two different methods for wrapping hypothermic patients with the goal to reduce evaporative heat loss. Eight volunteers randomly participated in two different scenarios were they either kept the wet clothing or got the wet clothing removed before being wrapped in a vapor barrier, a dry insulation layer, and a windproof thermal rescue bag. Each participant conducted both scenarios. Skin temperature were measured, and a questionnaire was recorded for a subjective evaluation of comfort, thermal sensation, and shivering. The study showed significant differences between the two groups.
