Liposomal bupivacaine plus bupivacaine versus ropivacaine for PENG block in hip replacement

Bupivacaine Liposome Plus Bupivacaine or Ropivacaine for PENG Block on Post Operative Pain Management in Patients Undergoing Hip Arthroplasty: a Prospective, Randomized, Single Blind, Active Controlled Study

Phase 4 Interventional Huazhong University of Science and Technology · NCT06565910

This trial will test whether adding liposomal bupivacaine to regular bupivacaine for a pericapsular nerve group (PENG) block gives longer and better pain relief than ropivacaine after hip replacement surgery.

What this trial studies

This is a single-center, phase 4 interventional trial enrolling patients undergoing hip arthroplasty for hip fracture who meet ASA I–II and normal coagulation criteria. Participants receive a PENG block and are assigned to receive either liposomal bupivacaine plus standard bupivacaine or ropivacaine. The study compares pain relief duration, overall analgesic efficacy, opioid consumption, patient satisfaction, and records adverse events to assess safety. Outcomes are measured in the immediate postoperative period and during standard postoperative follow-up.

Who should consider this trial

Good fit: Adults having hip arthroplasty for hip fracture who are ASA physical status I–II, have normal coagulation, and have no allergy to amide local anesthetics are the intended participants.

Not a fit: Patients with severe systemic disease (ASA III or higher), abnormal coagulation, or an allergy to amide local anesthetics would not be eligible and are unlikely to benefit from this intervention.

Why it matters

Potential benefit: If successful, this approach could provide longer-lasting pain relief after hip replacement and reduce the need for opioid medications.

How similar studies have performed: Liposomal bupivacaine has produced longer analgesia in some wound infiltration and peripheral block studies, but results are mixed and specific evidence for PENG block remains limited.
