Abstract:Objective To investigate the effect of transversus abdominis plane (TAP) block using ropivacaine combined with butorphanol tartrate on analgesia and stress response in patients undergoing laparoscopic total hysterectomy.Methods A total of 102 patients undergoing laparoscopic total hysterectomy at Bei'an First People's Hospital from December 2022 to December 2023 were selected and randomly divided into a control group (n = 51, receiving TAP block using ropivacaine) and a combination group (n = 51, receiving TAP block using ropivacaine combined with butorphanol tartrate). Perioperative indicators, Numeric Rating Scale (NRS) scores, Ramsay scores, Pittsburgh Sleep Quality Index (PSQI) scores, stress markers, Quality of Recovery-40 (QoR-40) scores, and incidence of adverse reactions were compared between the two groups.Results The combination group demonstrated shorter times to bowel sound recovery, first ambulation, and hospital discharge compared with the control group (P 0.05). The NRS scores at 2 h postoperatively and the PSQI scores on the first postoperative night were significantly lower in the combination group than in the control group (P 0.05), whereas the Ramsay scores at 2 h postoperatively were significantly higher in the combination group (P 0.05). The NRS scores at 12 h postoperatively and the PSQI scores on the second postoperative night remained significantly lower in the combination group than in the control group (P 0.05), while the Ramsay scores were significantly higher in the combination group (P 0.05). Furthermore, the changes in NRS and Ramsay scores from 2 h to 12 h postoperatively, as well as the change in PSQI scores from the first to the second postoperative night, were all significantly greater in the combination group than in the control group (P 0.05). At 24 h postoperatively, serum levels of cortisol (Cor), adrenocorticotropic hormone (ACTH), and angiotensin II (Ang II) were significantly lower in the combination group than in the control group (P 0.05). In addition, the changes in Cor, ACTH, and Ang II levels from preoperative baseline to 24 h postoperatively were significantly smaller in the combination group (P 0.05). The QoR-40 scores at 24 h and 48 h postoperatively were significantly higher in the combination group than in the control group (P 0.05). There was no statistically significant difference in the overall incidence of adverse events between the two groups (P 0.05).Conclusion TAP block using ropivacaine combined with butorphanol tartrate effectively reduces pain and stress response in patients undergoing laparoscopic total hysterectomy, promotes postoperative recovery with high a safety profile, and is worth widespread clinical application.
