2 participants in 2 patient groups

Subgluteal Sciatic Nerve Block

Active Comparator group

Description:

Patients randomized to this group will receive a sciatic nerve block with the catheter tip insertion at the subgluteal location 1-3 cm caudad to the inferior border of the gluteus maximus muscle.
