Pain management after surgery for peritoneal cancer

Quadratus Lumborum Block for Analgesia After Cytoreductive Surgery and Hyperthermic Intra-peritoneal Chemotherapy (CRS and HIPEC): a Double-blind Randomized Controlled Trial

Not applicable Interventional Gangnam Severance Hospital · NCT05597683

This study is testing if a special pain relief technique can help people who have surgery for peritoneal cancer feel less pain and use fewer opioids after their operation.

What this trial studies

This study evaluates the effectiveness of a transmuscular quadratus lumborum block (QL block) in reducing postoperative pain for patients undergoing cytoreductive surgery and hyperthermic intra-peritoneal chemotherapy (CRS and HIPEC). Participants will be randomly assigned to receive either the QL block with multimodal analgesia or standard multimodal analgesia alone. The primary outcome measured will be opioid consumption in the first 24 hours post-surgery, while secondary outcomes will include pain scores, time to first rescue analgesic, quality of recovery, and length of hospital stay. The study aims to improve pain management strategies for this patient population.

Who should consider this trial

Good fit: Ideal candidates are adult patients scheduled for cytoreductive surgery and hyperthermic intra-peritoneal chemotherapy.

Not a fit: Patients with allergies to local anesthetics, chronic pain, or those unable to communicate may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could significantly reduce postoperative pain and opioid consumption for patients undergoing CRS and HIPEC.

How similar studies have performed: Other studies have shown promising results with similar regional anesthesia techniques, suggesting potential for success in this approach.
