Comparing two methods for pain relief after hip replacement surgery

The Effect of Unilateral Erector Spinae Plane Block Versus Intrathecal Morphine on Early Mobilization After Total Hip Replacement Under Spinal Anesthesia in Cairo University Hospitals: a Prospective Randomized Clinical Study

Early Phase 1 Interventional Cairo University · NCT06621849

This study is testing whether a new pain relief method using a nerve block works better than morphine for helping people manage pain after hip replacement surgery.

What this trial studies

This clinical trial evaluates the effectiveness of a unilateral erector spinae plane block versus intrathecal morphine for managing postoperative pain in patients undergoing hip replacement surgery. A total of 70 adult participants will be randomly assigned to one of two groups, receiving either the erector spinae plane block or morphine as part of their anesthesia regimen. The study aims to assess early mobilization and pain control post-surgery through standardized pain scoring methods. Preoperative assessments will ensure participants meet specific health criteria before enrollment.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 to 60 with a body mass index between 20 and 30 who are undergoing elective hip replacement surgery.

Not a fit: Patients outside the age range of 18 to 60, those with contraindications to spinal anesthesia, or individuals with certain medical conditions may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved pain management strategies that enhance early mobilization after hip replacement surgery.

How similar studies have performed: Previous studies have shown promising results with similar pain management techniques, suggesting potential for success in this approach.
