Comparing Psoas Sheath Block and Fascia Iliaca Block for Pain Relief After Total Hip Replacement Surgery

What this Trial Is About

Researchers are evaluating the effectiveness of two different types of nerve blocks, the psoas sheath block and the suprainguinal fascia iliaca plane block, for managing pain after total hip arthroplasty surgery. This study is a single-center, assessor-blind, randomized controlled trial designed to compare these two methods for post-operative pain relief and recovery quality in patients undergoing hip replacement. Participants will be randomly assigned to receive either the psoas sheath block or the fascia iliaca block before their surgery. Both procedures involve ultrasound-guided injection of a local anesthetic called ropivacaine to help control pain. The psoas sheath block uses a low-frequency ultrasound probe and a longer needle to deliver the anesthetic into the subpsoas fascial plane, while the fascia iliaca block uses a high-frequency probe and a shorter needle to inject beneath the fascia iliaca. The procedure is performed by experienced anesthesiologists, and dose adjustments are made based on patient weight to reduce risks. During the study, participants will be closely monitored for pain levels, opioid use, and recovery quality. Assessments include pain rating scales at various times after surgery, total opioid consumption, mobility scores, distance mobilized, and patient satisfaction with pain management within the first 48 hours post-operation. Researchers will also track any opioid-related side effects. The study aims to provide unbiased results through concealed group allocation and blinded outcome assessment, with overall participation lasting through the immediate post-operative period.
