Evaluation of inhalation rewarming and peripheral rewarming for reducing the body core temperature afterdrop and accelerating rewarming rates.
Prospective, randomized human experimentation.
Physiology laboratory with cooling during ice water immersion and rewarming in rescue sleeping bags in a windy, cold (2 C) air environment.
Eight experimental subjects who were cooled to clinical hypothermia (35.0 C), rectal or esophageal temperature (Tr or Te).
Afterdrop was characterized as minimum Tr and Te plus recovery time to the Tr and Te levels at the onset of rewarming. Rewarming rates 30 and 60 minutes after maximum afterdrop for Tr and Te were measured. By analysis of variance, inhalation rewarming and peripheral rewarming evaluated separately or in combination did not significantly influence afterdrop duration, afterdrop recovery, or rewarming rates.
With no physiological benefit and hazards identified (inhalation rewarming burning the face, peripheral rewarming eliminating carbon monoxide equal to 300 to 600 ppm), inhalation rewarming and peripheral rewarming are not recommended for the prehospital treatment of mild hypothermia.
评估吸入复温和外周复温对降低体温过低后的体核温度下降及加快复温速度的效果。
前瞻性随机人体实验。
生理学实验室，在冰水浸泡期间进行降温，并在有风的2摄氏度寒冷空气环境中使用救援睡袋进行复温。
八名实验对象，其直肠或食管温度（Tr或Te）被降至临床低温（35.0摄氏度）。
体温下降的特征为最低Tr和Te加上复温开始时恢复到Tr和Te水平的时间。测量了Tr和Te在最大体温下降后30分钟和60分钟的复温速度。通过方差分析，单独或联合评估的吸入复温和外周复温对体温下降持续时间、体温下降恢复或复温速度均无显著影响。
由于未发现生理益处且存在风险（吸入复温会灼伤面部，外周复温会消除浓度相当于300至600 ppm的一氧化碳），不建议在院前治疗轻度低温时使用吸入复温和外周复温。
