Abstract

Tourniquet pressure rather than prolonged ischaemia is the main factor responsible for nerve palsies. It is essential to check the accuracy of the gauge of a pneumatic tourniquet against a mercury manometer regularly, as the commonest cause of a tourniquet paralysis is a faulty gauge. With regard to ischaemia three hours should be regarded as the upper limit of safety.

摘要

止血带压力而非长时间缺血是导致神经麻痹的主要因素。必须定期对照水银血压计检查气动止血带压力表的准确性，因为止血带麻痹最常见的原因是压力表故障。关于缺血，三小时应被视为安全上限。
