Comparison of PENG Block and Suprainguinal Fascia Iliaca Block for Facilitating Positioning in Hip Fracture Surgeries for Spinal Anesthesia: A Randomized Controlled Trial

Hip fracture surgeries in elderly patients often require spinal anesthesia, but positioning these patients for the procedure can be extremely painful due to fracture-related discomfort. Adequate regional analgesia before positioning improves patient comfort and facilitates successful spinal anesthesia. This randomized controlled trial aims to compare the efficacy of Pericapsular Nerve Group (PENG) block and Suprainguinal Fascia Iliaca (SIFI) block in improving patient comfort during positioning for spinal anesthesia in hip fracture surgeries. Sixty patients scheduled for hip fracture surgery under spinal anesthesia will be randomly allocated into two equal groups to receive either a PENG block or a SIFI block using 20 mL of 0.2percent Ropivacaine under ultrasound guidance. The primary outcome will be the pain score during positioning for spinal anesthesia. Secondary outcomes will include the time for optimal positioning, change in pain scores at baseline, 15 minutes and at the time for optimal positioning, the block onset time, ease of positioning, hemodynamic changes and any noted complications. This study aims to identify which of the two regional anesthesia techniques provides superior analgesia and facilitates optimal patient positioning for spinal anesthesia in hip fracture surgeries.
