ABSTRACT
Background and Aims:
Laparoscopic cholecystectomy (LC) is a widely accepted surgical procedure associated with postoperative pain. This study was done to compare peripheral nerve stimulator (PNS)-guided serratus anterior plane block (SAP) and transversus abdominis plane (TAP) block for postoperative analgesia for patients undergoing LC.
Methods:
Following approval from the ethical committee, 70 patients for LC were randomly assigned to Group S: SAP block and Group T: TAP block. The blocks were performed under PNS guidance, and 20 ml of 0.375% ropivacaine was administered. The severity of pain was measured using a visual analogue scale (VAS). The study’s primary objective was the evaluation of the postoperative VAS score. The time of the first dose of rescue analgesia and total tramadol consumption for 24 h postoperatively were secondary objectives. All the statistical calculation was done using statistical analyses for Social Sciences for Windows version 23.0 (IBM Corp, NY, USA).
Results:
Lower VAS score was seen in patients of TAP block at rest as well as movement at 6 h (
Conclusion:
TAP block guided by the PNS improves postoperative pain with less tramadol consumption and during the postoperative period without significant complications.
