Application of Ultrasound-Guided Transversus Abdominis Plane Block Combined with Nalbuphine Patient-Controlled Intravenous Analgesia in Postoperative Analgesia After Laparotomy: A Randomized Controlled Trial.

INTRODUCTION

Pain is a common postoperative complication. The ideal postoperative analgesia is awake, safe, mobile, and without side effects. The objective of this study is to provide new ideas for postoperative analgesia by observing the safety and analgesic effect of different analgesic methods in patients undergoing laparotomy after surgery.

METHODS

Patients, who underwent laparotomy between September 2019 and December 2020, were randomly divided into three groups: group S received sufentanil, group N received nalbuphine, group T + N received postoperative bilateral transversus abdominis plane block (TAPB) and nalbuphine. The primary outcomes included visual analog scale (VAS) score and the use of postoperative analgesic pump. Secondary outcomes included quality of life recovery (QoR-15) scale score and incidence of postoperative adverse reactions.

RESULTS

Compared with group S and N, there were significant differences in the resting VAS score within 48 h after surgery, dynamic VAS score within 12 h after surgery, the first compression time, and cumulative use of patient-controlled intravenous analgesia (PCIA) drugs at 24 h in group T + N (P < 0.05). The QoR-15 score within 48 h after surgery in group T + N was significantly higher than group N (P < 0.05). The first exhaust time and the incidence of nausea and vomiting in group T + N were significantly lower than those in group N (P < 0.05).

CONCLUSIONS

Sufentanil PCIA and nalbuphine PCIA have equivalent analgesic effects, while TAPB combined with nalbuphine PCIA can ensure a good analgesic effect, thereby reducing the incidence of adverse reactions.
