ObjectiveTo investigate the safety of propofol combined with cis-atracurium in the examination of fiberobronchoscopy under general anesthesia of laryngeal mask airway. MethodsAccording to different anesthetic drugs, 96 patients planed to receive fiberobronchoscopy examination were divided into group A(50 cases) and group B(46 cases). Patients of group A were given propofol combined with cis-atracurium, and patients of group B were given propofol combined with remifentanil.The onset time of, muscle relaxation recovery index and the incidence of complications of the two groups were compared. ResultsThere was no significant difference between the onset time of anesthesia of the two groups (P＞0.05); the incidence rate of complications of group A was lower than that of group B, and muscle relaxation recovery index was significantly higher than that of group B, the differences were statistically significant(P＜0.05). ConclusionPropofol combined with cis-atracurium using in the examination of fiberobronchoscopy under general anesthesia of laryngeal mask airway can improve muscle relaxation recovery index, and reduce the occurrence of complication. It’s security and worthyto popularize.
