Abstract

Background and aim: Transversus abdominis plane (TAP) block and local anesthetic infiltration (LAI) technique are used as part of the multimodal analgesic regimen after abdominal surgery. Postoperative opioid consumption and analgesic efficacy was compared using TAP and LAI techniques in patients undergoing gynecologic surgery in a randomized, controlled clinical trial.
Material and methods: Total of 135 patients scheduled for major gynecological surgeries were allocated into three groups: group T received bilateral TAP block with bupivacaine 0.25%; group I received LAI with 0.25% bupivacaine with epinephrine 5 μ/mL in the peritoneum and abdominal wall, and group C was control group. Anesthesia and postoperative analgesia were standardized. Outcome measures were cumulative and rescue tramadol consumption, numerical rating score (NRS) for pain and side effects in post-anesthesia care unit (PACU) at 4, 8, 12 hours postoperatively.
Results: Tramadol consumption, need for rescue analgesia, and NRS for pain between three groups at 4, 8, and 12 hours postoperatively had no statistically significant difference (P < 0.05). In PACU, median tramadol consumption used for rescue analgesia between group T (15 (15-30)) and group C (30 (15-45)) (P = 0.035), and between group T (15 (15-30)) and group I (30 (15-52)) was statistically significant (P = 0.034). In PACU, the percentage of patients having NRS >4 on movement in group C (72%) compared to group T (46.5%) and group I (46.5%) was significant (P = 0.034). No statistically significant difference was observed in the incidence of side effects among study groups (P > 0.05).
Conclusion: Except for the immediate postoperative period, neither TAP block nor LAI had added benefit to the multimodal analgesia regimen in patients undergoing gynecological surgeries.
