Abstract
Objective To study the effect of laryngeal mask combined with muscle relaxant free technique in treatment of patients with myasthenia gravis thymectomy and its effects on blood gas index ,respiratory function and complications .Methods A total of 78 patients with myasthenia gravis who underwent thymecto-my from April 2016 to March 2017 ,those patients were divided into observation group and control group ac-cording to random number method .The observation group used laryngeal mask combined with muscle relaxant free technique ,the control group used laryngeal mask combined with muscle relaxant technique .The blood gas index ,respiratory function ,intraoperative anesthesia dose and postoperative awakening and complication were compared between the two groups .Results Before anesthesia ,there was no significant difference in PaCO2, PaO2,SpO2 and pH between the two groups (P＞0 .05) ,at extubation ,there was no significant difference in PaCO2,pH values between the two groups (P＞0 .05) ,but PaO2 and SpO2 in the observation group were sig-nificantly higher than those in the control group (P＜0 .05).Before anesthesia ,there was no significant differ-ence in the levels of tidal volume (VT) ,inspiratory volume (TRV) ,expiratory replacement volume (ERV) , residual volume (RV) ,vital capacity (Vc) between the two groups (P＞0 .05).The awake time and extuba-tion time of the observation group were significantly shorter than those of the control group (P＜0 .05).The incidence of complications in the observation group was significantly lower than that in the control group (P＜0 .05).Conclusion Laryngeal mask combined with no muscle relaxant free technique can effectively stabilize the respiratory function of patients with myasthenia gravis ,and does not affect the blood gas function and re-duce the incidence of postoperative complications .关键词
