Objective To observe the effect of laryngeal mask airway(LMA) combined with sevoflurane inhalation anaesthesia in gynecological hysteroscopy operation. Methods Sixty patients, classified from ASAⅠtoⅡscheduled for hysteroscopic operation were randomly divided into sevoflurane inhalation anesthesia group (group A) and propofol intravenous anesthesia group(group B).The mean arterial pressure (MAP), pulse oxygen saturation (SpO₂), recovery time and the incidence of nausea, vomiting and recovery time were recorded at different time points of the two groups. Results The hemodynamic index of the patient in the group A fluctuated seldom,and the recovery time was significantly shorter than that in the B group, and the differences were significant (P<0.05).The MAP and the HR were all decreased after anesthesia induction compared with those of before in both groups (P<0.05).The MAP and the HR in the group B was significantly lower than that in the group A (P<0.05), there were no significant differences in MAP and HR between the two groups of patients with laryngeal mask airway removal. Conclusion Small hemodynamic influence is taken with the technique of laryngeal mask airway(LMA) combined with sevoflurane inhalation anesthesia. It is suitable for gynecological hysteroscopic operation.
