ABSTRACT
BACKGROUND: Transversus abdominis plane (TAP) block is a new regional anesthetic technique for postoperative pain control after lower abdominal surgery. We evaluated the analgesic efficacy of ultrasound-guided (US-) TAP block in patients undergoing lower abdominal surgery. METHODS: Thirty American Society of Anesthesiologists physical status I or II patients between 20-80 years of age undergoing lower abdominal surgery were randomized to receive standard care (n = 15) including intravenous patient-controlled analgesia (IV-PCA), or to undergo bilateral US-TAP block adjunctively (n = 15). A standard general anesthetic technique was used. After induction of anesthesia, bilateral US-TAP block was performed using total 30 ml of 2% lidocaine. Each patient was assessed postoperatively at 20, 30, and 60 min in postanesthesia care unit (PACU) and at 6, 12, and 24 h in ward for pain scores using verbal numerical rating scale (VNRS), analgesic requirements, quality of sleep, and complications. RESULTS: US-TAP block significantly reduced VNRS pain scores at 20, 30, and 60 min postoperatively (P < 0.001). The US-TAP block group required significantly fewer remifentanil intraoperatively (P < 0.05). Additional analgesic requirements were significantly lower in both PACU and ward (P < 0.05) in the US-TAP block group. There were no statistically significant between-group differences in total infused volume of IV-PCA, time to first requirement of analgesics in ward, and quality of sleep. CONCLUSIONS: US-TAP block with 2% lidocaine provided superior analgesia after lower abdominal surgery especially in the first 60 postoperative min when used as a component of a multimodal analgesic regimen.
