Objective To investigate the effect of sugammadex sodium on early postoperative pulmonary function in elderly patients undergoing laparoscopy-assisted colorectal tumor surgery. Methods Sixty elderly patients underwent elective abdominal surgery, 32 males and 28 females, aged 65-80 years, BMI 18-28 kg/m2, ASA physical status Ⅰ-Ⅲ, were randomly divided into two groups: sugammadex sodium group (group S) and neostigmine + atropine group (group NA), 30 patients in each group. After entering PACU, when the train of four stimulation (TOF) count was 2, group S was given sugammadex sodium 2 mg/kg, and group NA was given neostigmine 0.02 mg/kg + atropine 0.01 mg/kg. The endotracheal tube was removed when the ratio of TOF (TOFr) ≥ 0.9. The operation time, anesthesia time, intraoperative muscle relaxants dose used, the time between the last muscle relaxation and the end of the operation, the time between the end of the surgery and extubation time, the time of TOFr ≥ 0.9, the length of stay in PACU and the hospitalization time were recorded. Pulmonary function, including forced vital capacity (FVC), forced expiratory volume in 1 second (FEV1) and FEV1/FVC was tested before surgery, 30 minutes and 24 hours after extubation. Postoperative pulmonary complications (hypoxaemia, upper airway obstruction, postoperative pneumonia, atelectasis, hydrothorax and pneumothorax) and adverse reactions were recorded. Results There were no differences in operation time, anesthesia time, intraoperative muscle relaxants dose used, the time between the last muscle relaxation and the end of the operation hospitalization time. Compared with group NA, the time from the end of surgery to extubation, the time of TOFr ≥ 0.9 and the length of stay in PACU were shortened significantly in group S. There were no differences in pulmonary function (FVC, FEV1 and FEV1/FVC) between the two groups before surgery and 30 minutes and 24 hours after extubation. There were no differences in postoperative pulmonary complications and adverse events between the two groups. Conclusion Sugammadex sodium can more rapidly antagonize the residual muscle relaxants, but sugammadex sodium does not improve pulmonary function and postoperative pulmonary complications at the early stage after laparoscopy-assisted colorectal tumor surgery in elderly patients. |
