Objectives: The aim of this study was to compare a transversus abdominis plane (TAP) block guided with ultrasound (USG) and local anesthetic infiltration (LAI) in terms of the intraoperative and postoperative analgesia efficiency, intraoperative opioid need, and side effects in cases of laparoscopic cholecystectomy. Methods: A total of 75 patients classified as American Society of Anesthesiologists class I or II were included in this randomized, controlled, prospective study and divided into 3 groups. 20 mL of levobupivacaine 0.5% was applied around the trocar entrance site before the operation to group L (n=25), and 30 mL 0.25% levobupivacaine was applied with a USG-guided TAP block to group T (n=25). No TAP block or LAI was applied to the control group (n=25), group K. In the first 24 hours after surgery, an infusion of tramadol was administered with a controlled analgesia device. The intraoperative fentanyl use was recorded, and a visual analogue scale was administered to assess pain while resting (VASrest) and upon coughing (VAScough) at 1, 2, 4, 8, 12, 16, and 24 hours postoperative. An evaluation of shoulder pain and the consumption of analgesia in 24 hours were also recorded. Results: The VASrest and VAScough values, the dose of fentanyl used intraoperatively, and the total analgesia dose administered in 24 hours were compared between groups and there was no statistically significant difference detected (p>0.05). In group T, the vomiting rate 1 and 2 hours postoperative (20% and 12%, respectively) was significantly lower than in group K (64% and 44%, respectively). Conclusion: The efficiency of the analgesia provided after a laparoscopic cholecystectomy with a bilateral TAP block guided with USG and LAI was determined to be similar.
