Abstract:
Objective:To evaluate the efficacy of sugammadex for the reversal of residual neuromuscular blockade after laparoscopic radical gastrectomy in elderly patients.Methods:Sixty patients of both sexes, aged 65-85 yr, with body mass index of 20-26 kg/m 2, of American Society of Anesthesiologists physical status Ⅰ-Ⅲ, undergoing elective laparoscopic radical gastrectomy under general anesthesia, were divided into 2 groups ( n=30 each) by a random number table method: sugammadex group (S group) and neostigmine group (N group). Rocuronium 0.3-0.6 mg·kg -1·h -1 was intravenously infused during operation, and the muscle relaxation was monitored by a Veryark-TOF monitor, maintaining TOF ratio=0 and counting 1 or 2 after tonic stimulation.Rocuronium was discontinued when the peritoneum was closed.The patients were admitted to the PACU after operation.When the muscle relaxation monitoring T 2 appeared, sugammadex 2 mg/kg was intravenously injected in S group, and neostigmine 0.03 mg/kg plus atropine 0.015 mg/kg was intravenously injected in N group.The tracheal tube was removed after the patient′s consciousness and spontaneous breathing recovered.Before anesthesia (T 1) and 5 and 30 min after tracheal extubation (T 2, 3), arterial blood samples were collected for blood gas analysis, PaO 2 and PaCO 2 were recorded, and ultrasound was used to measure the diaphragm end-inspiratory thickness, end-expiratory thickness and mobility of diaphragm muscle at the above time points.The diaphragm thickening fraction was calculated.The time of T 2 appeared, time of extubation, time of postanesthesia care unit (PACU) stay, postoperative hospital stay, and residual neuromuscular blockade (TOF ratio <0.9) and hypoxemia occurred within 30 min after extubation were recorded.The pulmonary complications within 7 days after operation were recorded. Results:Compared with group N, PaO 2 was significantly increased and PaCO 2 was decreased at T 2, 3, the mobility of diaphragm muscle and diaphragm thickening fraction were increased at T 2, the tracheal extubation time, time of PACU stay and postoperative hospital stay were shortened, the residual neuromuscular blockade and hypoxemia occurred after extubation and incidence of pulmonary complications after operation were decreased ( P<0.05), and no significant change was found in the time of T 2 appeared in group S ( P>0.05). Conclusion:Sugammadex can quickly and effectively reverse the residual neuromuscular blockade after laparoscopic radical gastrectomy, which is helpful for early postoperative recovery in elderly patients.
