Abstract

In vitro coagulation times and in vivo bleeding times were proportionally prolonged as the rabbit ear temperature was lowered from ambient temperature to 1 degree C. Cooling of the ear caused an increase in bleeding rather than the decrease generally attributed to cold application. The effects of temperature on the various aspects of hemostasis are discussed, and the pertinent literature is reviewed. An optimal nonfreezing cold temperature which could consistently enhance hemostasis could not be determined.

摘要

随着兔耳温度从环境温度降至1℃，体外凝血时间和体内出血时间成比例延长。耳部冷却导致出血增加，而非通常认为的冷敷所致的出血减少。本文讨论了温度对止血各个方面的影响，并回顾了相关文献。未能确定一个能持续增强止血效果的最佳非冷冻低温。
