Postoperative low-dose sufentanil combined with transversus abdominis plane block promotes recovery following laparoscopic hysterectomy

To compare the efficacy and safety of postoperative analgesia with low-dose sufentanil combined with transversus abdominis plane (TAP) block and with sufentanil alone in promoting patients'recovery following laparoscopic hysterectomy. Sixty patients undergoing laparoscopic hysterectomy in our hospital between September, 2016 and August, 2017 were randomly allocated into two equal groups. In group A, the patients were given postoperative analgesia with 1 μg/kg sufentanil, 9.96 mg tropisetronmesylate, and 200 mg flurbiprofen axetil (diluted with 0.9% NaCl solution to 100 mL, pumped at the rate of 2 mL/h) combined with TAP block; in group B, the patients received similar postoperative analgesia but at a higher dose of sufentanil (2 μg/kg) without TAP block. Visual analogue scale (VAS) was used to evaluate pain at 15 min and at 4, 8, 12, 24 and 48 h postoperatively, and the first off-bed time, the length of postoperative hospital stay and the incidence of postoperative nausea and vomiting (PONV) were recorded in
