Continuous epidural anesthesia, started 6 h after severe cold injury of the extremities and continued for 3 days, resulted in complete clinical remission of the frozen areas of the feet. In contrast, repeated stellate ganglion block, started 72 h after cold injury, failed to prevent the development of necroses in the frozen parts of the hands, so that plastic surgery was required.
连续硬膜外麻醉在四肢严重冻伤6小时后开始，持续3天，导致足部冻伤区域完全临床缓解。相比之下，在冻伤72小时后开始的反复星状神经节阻滞未能防止手部冻伤部位坏死的发展，因此需要进行整形手术。
