Is this trial a fit for you?

Likely a good fit

Ideal candidates are adults over 18 years old who are undergoing elective laparoscopic cholecystectomy and classified as ASA I-III.

Probably not a fit

Patients with coagulopathy, infections at the block site, or those undergoing open surgery may not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This study evaluates the effectiveness of two analgesic techniques, the modified thoracoabdominal nerve block through perichondrial approach (M-TAPA) and the transversus abdominis plane (TAP) block, for managing postoperative pain following laparoscopic cholecystectomy. The research focuses on adult patients undergoing this common abdominal surgery, aiming to determine which method provides superior pain relief. By utilizing ultrasound guidance for both techniques, the study seeks to enhance patient comfort and recovery outcomes. The findings could contribute to improved pain management protocols in surgical settings.

Why it matters

Potential benefit: If successful, this study could lead to more effective pain management strategies for patients undergoing laparoscopic cholecystectomy.

How similar studies have gone: Previous studies have shown the effectiveness of TAP blocks for postoperative pain relief, but the M-TAPA technique is relatively novel and less tested.
