Abstract:
Objective:To evaluate the efficacy of liposomal bupivacaine transversus abdominis plane block (TAPB) in combination with general anesthesia for elderly patients undergoing laparoscopic radical resection of colorectal cancer.Methods:In this randomized controlled trial, 70 American Society of Anesthesiologists Physical Status classification Ⅱ or Ⅲ patients, aged 60-80 yr, with body mass index of 18-28 kg/m 2, scheduled for elective laparoscopic radical resection of colorectal cancer at the General Hospital of Ningxia Medical University from September 2023 to June 2024, were divided into 2 groups ( n=35 each) using a table of random numbers: liposomal bupivacaine group (LB group) and hydrochloride bupi-vacaine group (HB group). After anesthesia induction, bilateral TAPB was performed under ultrasound guidance. In LB group, 0.44% liposomal bupivacaine 30 ml was injected on each side. In HB group, 0.25% hydrochloride bupivacaine 30 ml was injected on each side. Total intravenous anesthesia was adopted for both groups. Patient-controlled intravenous analgesia (PCIA) with sufentanil was carried out after surgery. When the visual analogue scale (VAS) score at rest was ≥ 4 within 72 h after surgery, hydromorphone 0.5 mg was intravenously injected for rescue analgesia. The area under the curve of VAS scores at rest and during activity was calculated within 12-72 h after surgery. The first pressing time of patient-controlled analgesia (PCA) and the effective pressing numbers of PCA, requirement for rescue analgesia, and score for satisfaction with analgesia were recorded. The sleep quality on 1 day before surgery and 1, 2 and 3 days after surgery was evaluated using the Richards-Campbell Sleep Questionnaire. The occurrence of adverse reactions, duration of post-anesthesia care unit stay, time to first ambulation, time to first flatus, and time to first oral intake, and postoperative length of hospital stay were recorded within 72 h after surgery. Results:Compared with HB group, the area under the curve of VAS scores at rest and during activity was significantly reduced at 12-72 h after operation, the first pressing time of PCA was prolonged, and the effective pressing numbers of PCA was reduced, the rate of rescue analgesia was decreased, the score for satisfaction with analgesia was increased, the Richards-Campbell Sleep Questionnaire scores were increased on the 2nd and 3rd days after surgery, the duration of post-anesthesia care unit stay and postoperative length of hospital stay were shortened, and the incidence of postoperative nausea was decreased in LB group ( P<0.05). Conclusions:The efficacy of liposomal bupivacaine TAPB combined with general anesthesia is superior to that of hydrochloride bupivacaine TAPB combined with general anesthesia in elderly patients undergoing laparoscopic colorectal cancer radical resection.
