Abstract:
Objective To investigate the effect of ultrasound-guided transverses abdominis plane (TAP)block on the efficacy of postoperative analgesia in patients undergoing abdominal hysterectomy. Methods Sixty ASA Ⅰ - Ⅱ patients scheduled for abdominal hysterectomy under general anesthesia were randomly divided into 2groups (n = 30 each): ropivacaine group (group R) and normal saline (group NS). After induction of anesthesia,ultrasound-guided bilateral TAP block was performed, and 0.375% ropivacaine 40 ml was injected in group R,while the equal volume of normal saline was used instead in group NS. The patients received patient-controlled intravenous analgesia (PCIA) with sufentanil after operation. The VAS score was maintained ≤ 3, the level of sedation was evaluated with Ramsay sedation score, and the comfort level was evaluated with Bruggrmann comfort scale (BCS) score at 2, 6, 8, 12 and 24 h after operation. The hemodynamic parameters were recorded. The consumption of sufentanil during operation and within 24 h after operation, the number of successfully delivered doses ( D1 )and the number of attempts ( D2 ) within 24 h after operation were recorded. D1/D2 was calculated. The adverse reactions were also recorded. Results SP, DP, HR, SpO2 and RR were in the normal range and there was no significant differences between the two groups ( P ＞ 0.05). The consumption of sufentanil were significantly lower,while the BCS score and D1/D2 higher in group R than in group NS (P ＜ 0.05). There were no adverse reactions in both groups. Conclusion Ultrasound-guided TAP block reduces the perioperative sufentanil consumption and enhances the efficacy of postoperative analgesia in patients undergoing abdominal hysterectomy.
