Comparing different methods of pain management during bariatric surgery

Comparison of the Efficacy of Celiac Plexus Blockade, Erector Spinae Compartment Blockade (ESP), and Intravenous Lidocaine Infusion Under Opioid-free Anesthesia in Patients Undergoing Bariatric Surgery

Not applicable Interventional Jagiellonian University · NCT06793527

What this trial studies

This study evaluates the effectiveness of three different pain management techniques during laparoscopic bariatric surgery: erector spinae plane (ESP) block, celiac plexus block, and intravenous lidocaine infusion. Patients will be randomly assigned to one of the three groups, with pain intensity assessed at various intervals post-surgery. The goal is to determine which method provides the best analgesia while minimizing opioid use and its associated side effects. All patients will receive a standardized opioid-free anesthesia protocol during the procedure.

Who should consider this trial

Good fit: Ideal candidates are adults over 18 years undergoing laparoscopic bariatric surgery who can provide informed consent.

Not a fit: Patients with a history of drug addiction, chronic pain requiring analgesics, or 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 reduce reliance on opioids in bariatric surgery.

How similar studies have performed: While there is ongoing interest in non-opioid analgesic techniques, this specific comparison of ESP and celiac plexus blocks in bariatric surgery is relatively novel.
