[Effects of patient-controlled intravenous analgesia with butorphanol versus sufentanil on early postoperative rehabilitation following radical laparoscopic nephrectomy].

ABSTRACT

Objective: To investigate the effects of patient-controlled intravenous analgesia with butorphanol versus sufentanil on early postoperative rehabilitation following radical laparoscopic nephrectomy. Methods: One hundred patients undergoing radical laparoscopic nephrectomy in Affiliated Cancer Hospital of Zhengzhou University from September 2018 to February 2020 were divided into two groups (n=50) using a random number table butorphanol patient-controlled intravenous analgesia group (group A) and sufentanil patient-controlled intravenous analgesia group (group B). Patient-controlled intravenous analgesia (PCIA) was performed at the end of surgery. The formulation of group A was butorphanol (0.15 mg/kg) and ketorolac tromethamine (180 mg) using the physiological saline at a dilution of 100 ml. The formulation of group B was sufentanil (1.5 µg/kg) and ketorolac tromethamine (180 mg) using the physiological saline at a dilution of 100 ml. At the time points of 4, 8, 24, 48 h after operation (T(1), T(2), T(3), T(4)), VAS scores at rest and cough were recorded. The incidence of remedial analgesia, the number of pressings during 48 h after the operation, the postoperative anal exhaust recovery time of the patients were recorded. Quality of recovery-40(QoR-40) scores were recorded at T(3) and T(4). Adverse reactions were recorded. Results: There was no significant difference in VAS scores at rest and cough at T(1), T(2), T(3) and T(4) between two groups (all P>0.05). There was no significant difference in the incidence of remedial analgesia and the number of pressings during 48 h after the operation between two groups (all P>0.05). The postoperative anal exhaust recovery time of the patients in group A was (32±6) h, which was lower than that in group B with statistically significant difference [(40±5) h, t=7.937, P<0.01]. The QoR-40 total scores in group A were higher than those in group B at T(3) and T(4), which were (185.8±2.5) vs (170.7±2.7), (194.8±1.9) vs (183.6±2.6), and the differences were statistically significant (t=28.878, 25.025, all P<0.01). The incidence of nausea, retching/vomiting, respiratory depression and itch during 48 h after the operation in group A were 10%, 6%, 2%, 2%, which were lower than that in group B (32%, 20%, 14%, 18%), with statistically significant difference (χ(2)=7.294, 4.322, 4.891, 5.983, all P<0.05). Conclusion: PCIA with butorphanol or sufentanil can provide satisfactory analgesia for patients undergoing radical laparoscopic nephrectomy, but butorphanol can promote postoperative rehabilitation with fewer adverse reactions.
