Bath rewarming from immersion hypothermia.
Trunk-only bath rewarming has often been recommended over whole-body bath rewarming as a method for the treatment of immersion hypothermia. At present, no report of a direct comparison of the relative merits of these techniques has been made. Authorities in favor of trunk-only bath rewarming base their proposal on the assumption that core temperature afterdrop would be minimized by preventing peripheral vasodilation when the subject's limbs are not immersed in the rewarming bath. In the present study, trunk-only and whole-body bath rewarming are compared by rewarming eight mildly hypothermic male subjects twice, once via each technique. It was concluded that trunk-only rewarming is not superior to whole-body bath rewarming as a therapy for mild immersion hypothermia, based on the findings that no significant differences existed between the two techniques, either in size or duration of core temperature afterdrop, or in rate of rewarming.
