Abstract:
Objective To compare the effects of subgluteal(SG) and sub-subgluteal-fold(SSGF)approach for ultrasound-guided siatic nerve block. Methods One hundred forty-eight patients undergoing lower limb surgery were randomly divided into two groups to receive SG approaches and SSGF approaches to sciatic nerve block under real time ultrasound guidance. A combined posterior lumbar plexus block under ultrasound guidance was performed for sufficient surgery anesthesia. 20 ml of 0. 5% ropivacaine was used for sciatic nerve and lumbar plexus block separately. Measurements included skin-to-nerve distance,reorientation of the needle during block and execution time,rates of sensory and motor blockade after 15 min and 30 min of injection, quality of surgery blockade, duration of the sensory and motor block, and postoperative complications related to sciatic nerve block. Results In SSGF group, execution time and reorientation of needle for sciatic nerve block was significantly less than those of the SG group( P ＜0.01).But motor blockade in the SG group was quicker when compared with SSGF group ( P ＜0.01). There were no significant differences in the quality and duration of blockade between the two groups. Conclusions Both SG and SSGF approach can be used for sciatic nerve block with equal sensory and motor block rate,whereas sciatic nerve block via SSGF approach was faster and easy to perform than the SG one.
