Comparing M-TAPA and TAP Nerve Blocks for Pain Relief After Laparoscopic Gallbladder Surgery

What this Trial Is About

Laparoscopic cholecystectomy is the most common abdominal surgery for treating gallstones, and managing postoperative pain after this procedure is important. This research compares two nerve block techniques, the established transversus abdominis plane TAP block and the newer modified thoracoabdominal nerve block through perichondrial approach M-TAPA, to see which is more effective for pain relief after surgery. Participants receive either a bilateral M-TAPA block or a bilateral TAP block using 0.25% bupivacaine 40 ml total at the end of their laparoscopic cholecystectomy. Both blocks are guided by ultrasound and performed before surgery starts, with the same procedure applied to both sides of the body. The study randomly assigns patients to one of these two nerve block groups. During the study, patients pain levels will be measured using a numerical rating scale over the first 24 hours after surgery. Researchers will also track the amount of tramadol pain medication used in that period. Participants will be monitored closely to assess pain control and any side effects. The study runs until early 2025, aiming to improve pain management after gallbladder surgery.
