Comparing Deep Iliacus Plane Block and Suprainguinal Fascia Iliaca Block for Pain Relief After Hip Replacement Surgery

What this Trial Is About

Researchers are comparing two types of nerve block techniques, the Deep Iliacus Plane Block DIPB and the Suprainguinal Fascia Iliaca Block SIFIB, to manage pain after primary total hip arthroplasty surgery. The goal is to find out which method provides better pain relief with fewer side effects like motor weakness. This clinical trial is randomized, double-blind, and controlled, involving patients under spinal anesthesia undergoing hip replacement. Seventy patients will be randomly assigned to receive either DIPB or SIFIB at the end of their surgery. Both procedures involve ultrasound-guided injections of 0.25% bupivacaine 30-40 mL adjusted by weight for postoperative pain control. The SIFIB targets mainly the femoral and lateral femoral cutaneous nerves but may miss deeper joint nerves, while DIPB aims to cover both superficial and deep nerves with potentially less motor impairment. Participants will be monitored for 48 hours after surgery, with pain levels measured at rest and during movement at specific times up to 48 hours. Opioid use, motor block severity using the modified Bromage scale, and any complications related to the blocks will also be recorded. This study assesses pain intensity, opioid consumption, motor block, and other outcomes to determine the best approach for safe and effective pain management after hip arthroplasty.
