Comparison of transversus abdominis plane block and intrathecal morphine for laparoscopic donor nephrectomy: Randomised controlled trial

Background and Aims: Postoperative pain following laparoscopic donor nephrectomy (LDN) is significant and no suitable analgesic technique is described. Opioid analgesia in standard doses is often suboptimal and associated with numerous adverse effects. Transversus abdominis plane (TAP) block has bee...

Description
Summary:Background and Aims: Postoperative pain following laparoscopic donor nephrectomy (LDN) is significant and no suitable analgesic technique is described. Opioid analgesia in standard doses is often suboptimal and associated with numerous adverse effects. Transversus abdominis plane (TAP) block has been evaluated in various laparoscopic procedures. Intrathecal morphine (ITM) has been seen to provide long-lasting analgesia of superior quality in laparoscopic colorectal procedures. Methods: The present study was undertaken to evaluate the analgesic efficacy of single-dose ITM 5 μg/kg for LDN. After ethics approval, 60 adult patients scheduled for LDN were randomised to receive intravenous fentanyl, ultrasound-guided TAP block or ITM for postoperative analgesia. Postoperative 24-h patient-controlled analgesia (PCA) fentanyl consumption, visual analogue scale (VAS) score and intraoperative fentanyl and muscle relaxant requirements were compared. Statistical analysis was performed using appropriate statistical tests by using Stata 11.1 software. Results: Haemodynamic stability at pneumoperitoneum and in the post anaesthesia care unit was significantly better in patients receiving ITM. Intraoperative rescue fentanyl requirement (P = 0.01) and postoperative fentanyl requirement until 24 h (P = 0.000) were significantly lower in the morphine group. Postoperative VAS at rest and on movement was significantly lower in the morphine group at all points of assessment (P = 0.000). Conclusion: ITM 5 μg/kg provides better intraoperative and postoperative analgesia and reduces postoperative PCA fentanyl requirement in laparoscopic donor nephrectomy compared to TAP block or intravenous fentanyl.
