Postoperative Analgesic Effect of Subcostal TAPB for Laparoscopic Gastrectomy

2019-10-29 14:36:35 | BioPortfolio


This prospective, randomized, single blinded study is designed to evaluate the postoperative analgesic efficacy of the ultrasound-guided subcostal transversus abdominis plane block in gastric cancer patients undergoing laparoscopic gastrectomy. We hypothesize that US guided subcostal TAP block with ropivacaine can significantly reduce postoperative opioid comparison in patients with laparoscopic gastrectomy.


Adult patients undergoing elective laparoscopic gastrectomy are randomly allocated to receive subcostal TAP block (n=55) or not, in addition to a standard postoperative analgesic regimen comprising of IV fentanyl-based patient-controlled analgesia (PCA) and NSAIDs as required. At the end of surgery, the TAP group patients will receive bilateral subcostal TAP block under ultrasound guidance with 15ml of 0.375% ropivacaine bilaterally. Each patient was assessed by a blinded investigator at 12, 24, and 48 h postoperatively. The primary outcome is total fentanyl consumption at 24 h after surgery.
