There is no rule as to how long a tourniquet may be safely inflated. The time may vary with the age of the patient and the vascular supply of the extremity. In an average healthy adult under 50 years of age, we prefer to leave the tourniquet inflated for no more than 2 hours. If an operation on the lower extremity takes longer than 2 hours, it is better to finish it as rapidly as possible than to deflate the tourniquet for 10 minutes and then reinflate it.

目前还无法证实止血带使用多长时间是安全的，这个时限可能因患者的年龄及肢体的血供而异。50岁以下的健康成人，我们一般掌握止血带的单次使用时限不超过2小时，如果下肢的手术需要2小时以上时，应设法尽快完成手术，这比松开止血带10分钟后，再次将止血带充气更好。
