The effect of butorphanol on pulmonary complications after thoracoscopic surgery
Objective To observe the effect of butorphanol on the incidence of postoperative pulmonary complications(PPCs)within 7 days after thoracoscopic surgery.Methods Patients who plan to undergo thoracoscopic surgery on a scheduled date were divided into a butorphanol group(group B)and a control group(group C)using a random number table method.The group B received intravenous injection of butorphanol 10μg/kg during anesthesia induction,followed by continuous infusion of butorphanol 10 μg/(kg·h)until the end of the operation.The group C was given an equal volume of normal saline.The types of postoperative pulmonary complications such as pneumonia,atelectasis,pleural effusion,pneumothorax,bronchospasm and inhalation lung injury within 7 days after operation,postoperative hospital stay,other complications and Visual Analogue Scale(VAS)pain scores were compared between the two groups.Results Within 7 days after operation,41 cases of PPCs occurred in the group B,that was lower than 62 in the group C(P＜0.05).The incidence rate of two or more types of PPCs and postoperative hospitalization days in the group B were lower or shorter than those in the group C and the incidence of postoperative dizziness in the group B was higher than that in the group C(P＜0.05).There was no difference in the incidence of other PPCs between the two groups(P＞0.05).Within 24 hours after surgery,the VAS pain score in the group B was lower than that in the group C(P＜0.05).Conclusions Butorphanol can reduce the incidence of pulmonary complications within 7 days and shorten the postoperative hospital stay in patients undergoing thoracoscopic surgery.
