Comparison of Postoperative Analgesia Methods in Patients Undergoing Major Intraabdominal Surgery

Not Applicable

Completed

• Conditions: Abdomen Disease; Abdominal Cancer

• Registration Number: NCT06384677
• Lead Sponsor: Marmara University

Brief Summary

This study aims to examine the effects of M-TAPA applied for postoperative analgesia in patients who had major intraabdominal surgery on the postoperative pain score, the change in the postoperative total opioid requirement and the side effects.

Detailed Description

The investigators seperated the patients into two groups as M-TAPA applied group and control group.In group M-TAPA, M-TAPA block was performed bilaterally with 20 mL of 0.2% bupivacaine under ultrasound guidance at the end of surgery. No block was performed in the control group. The participants were administered morphine through patient controlled analgesia (PCA) pump with a bolus dose of 1 mg, 15 min lockout interval. The postoperative pain scores (the numeric rating scores (NRS)), total opiod consumption in the first 48 h, and opioid related side effects were recorded.
