Ultrasound-guided Sciatic Nerve Block Using the Subgluteal Space Injection Approach: A Comparison With the Infragluteal Approach
In Brief
A clinical study evaluating Infragluteal space group and Subgluteal space group for Neuromuscular Blockade. Completed, enrolled 27 participants across 1 site.
Detailed Summary
A new ultrasound-guided "subgluteal space" approach to sciatic nerve block that has been recently described obviates the need to identify the sciatic nerve. The investigators hypothesize that the use of an ultrasound-guided subgluteal space injection to perform sciatic nerve block will increase the proportion of patients experiencing complete sensory block in both terminal branches of the Sciatic nerve in comparison to the same proportion in those who receive the block via ultrasound-guided infragluteal approach with circumferential injection in patients scheduled for unilateral TKA(total knee arthroplasty) surgeries.
Study Details
Timeline
Interventions
Sciatic Nerve Block "Infragluteal group": Ultrasound scanning will be used to identify and mark the greater trochanter laterally and the ischial tuberosity medially. The midpoint between these two structures is a rough non-binding estimate of the approximate location of the sciatic nerve. The sciatic nerve is usually found anterior (deep) to the gluteus maximus muscle and lateral to the origin of the biceps femoris muscle at the ischial tuberosity as well as medial to the greater trochanter. The end point of nerve block in this group is obtaining a circumferential local anesthetic spread around the sciatic nerve.
Subgluteal space group: The operator will identify the gluteus maximus and biceps femoris muscles at the level of the greater trochanter and ischial tuberosity and the infragluteal space.
