BACKGROUND: Optimal analgesia following laparoscopic colorectal resection is yet to be determined; however, recent studies have questioned the role of postoperative epidural anaesthesia, suggesting other analgesic modalities may be preferable. The aim of this randomised controlled trial was to assess the effect of transversus abdominis plane (TAP) blocks on opioid requirements in patients undergoing laparoscopic colorectal resection. METHODS: After appropriate trial registration ( NCT 00830089) and local medical ethics review board approval (REC 09/H0407/10), all adult patients who were to undergo laparoscopic colorectal surgery at a single centre were randomised into the intervention group receiving bilateral TAP blocks or the control group (no TAP block). The blocks were administered prior to surgery after the induction of a standardised anaesthetic by an anaesthetist otherwise uninvolved with the case. The patient, theatre anaesthetist, surgeon, and ward staff were blinded to treatment allocation. All patients received postoperative analgesia of paracetamol and morphine as a patient-controlled analgesia (PCA). Cumulative opioid consumption and pain scores were recorded at 2, 4, 6, and 24 h postoperatively and compared between the groups as were clinical outcomes and length of stay. RESULTS: The intervention (TAP block) group (n = 33) and the control group (n = 35) were comparable with respect to characteristics, specimen pathology, and type of procedure. The TAP block group's median cumulative morphine usage (40 mg [IQR = 25-63]) was significantly less than that of the control group (60 mg [IQR = 39-81]). Pain scores and median length of stay (LOS) were similar between the two groups. CONCLUSION: Preoperative TAP blocks in patients undergoing laparoscopic colorectal resection reduced opioid use in the first postoperative day in this study.
