Clinical Trial Summary

Postoperative pain after laparoscopic hepatectomy is composed of multiple factors, and the peak pain of postoperative pain mainly occurs within the first 24 hours, so it is particularly important to find an appropriate analgesic method. Transversus abdominis plane block (TAPB) and Rectus sheath blocks (RSB) are widely used in abdominal surgery, but too deep a needle tip during RSB may puncture abdominal organs. TAPB and RSB can only provide somatic analgesia, but lack visceral analgesia. Recently, Erector spinae plane block (ESPB) has been used in some studies for analgesia after abdominal surgery. The purpose of this study is to compare the analgesic effect and postoperative recovery effect of erector spinae plane block and transverse abdominis plane block combined with rectus sheath block in patients undergoing laparoscopic hepatectomy. Therefore, this study has important clinical implications.


Clinical Trial Description

In a double-blind randomized controlled study, researchers randomized 60 patients undergoing laparoscopic hepatectomy to TAPB combined with RSB or ESPB, with both groups receiving additional standardized treatment, including multimodal analgesia. The main outcome was the consumption of morphine within 24 hours after surgery. Secondary outcomes included the number of rescue analgesia at 1h, 2h, 4h, 8h and 24 hours after surgery, VAS scores in resting and coughing at 1h, 2h, 4h, 8h and 24h after surgery, CVP values at 5, 10, 15 and 30min after nerve block, QoR-15 patient questionnaire scores before and 24h after surgery, and postoperative liver function (the percentage increase of AST and ALT compare with preoperative), postoperative complications and discharge time. ;
