肢体局部降温安全延长止血带时间

A Clinical Application of Local Hypothermia to Safely Prolong Tourniquet Time

60年代Palett等提出用局部降温使肢体处于冷缺血状态以延长一次安全使用止血带时间的方法。其后関对此在实验研究及临床应用上予以完善。作者根据与関共同工作的体会,对降温袋及降温方法进行了适合我国国情的改良,应用于临床38例,取得满意效果。一次使用止血带4h31min亦未发生血管、神经、肌肉及皮肤并发症。作者详细地介绍了操作方法,并对止血带损伤组织及降温对组织保护的机理进行了讨论。

Local hypothermia was studied as a method to safely prolong tourniquet time for operative procedures of the extremities. In the paper, local hypothermic materials and techniques were described, and the mechanism of decreasing the adverse effects of tourniquet injury with local hypothermia was discussed. There were no postoperative complications associated with the continuous tourniquet time of four hours and 31 minutes. Local hypothermia appears to be a safe, simple, effective, and inexpensive method of reduceing metabolic level and anti-reperfusive injury. With this method, continuous tourniquet time may be safely extended beyond the customary two hour limit.
