简要总结
The aim of this prospective, randomized, observer-blind study to compare subparaneural approach injection with interneural approach injection in popliteal sciatic nerve blocks.
详细描述
The study will involve American Society of Anesthesiologists Physical Status Classification (ASA) III or IV risk group patients, 18 years of age or older, who will undergoing foot, ankle, or toe amputation.
Supparaneural injection (Group S) and interneural injection method (Group I) will the two research groups to which patients were randomly allocated.
Every 5 minutes following LA injection, an investigator who will blind to randomization will assess the sensory and motor blockage in the operated foot. The study will documented the operative time, block characteristics, such as the duration of block administration, sensory and motor block start and regression times, the time of extra analgesic required, and the occurrence of complications.

时间窗: Time from the moment the block is made to the moment it starts, within the first half hour
Onset time will be defined as the moment when it is determined that the block is successful.
