喉罩通气下全凭七氟醚吸入麻醉在妇科宫腔镜手术中的应用

The application of laryngeal mask airway combined with sevoflurane inhalation anesthesia in gynecological hysteroscopy operation

目的观察喉罩通气下全凭七氟醚吸入麻醉在妇科宫腔镜手术中的应用价值。方法 60例拟行妇科宫腔镜手术的患者随机分为七氟醚和丙泊酚组,每组30例,记录不同时间点两组患者的平均动脉压(MAP),脉搏血氧饱和度(Sp O2)、苏醒时间以及术后恶心,呕吐、躁动的发生率。结果 A组患者血流动力学指标波动较少,苏醒时间A组明显短于B组,差异有显著性(P<0.05)。两组患者诱导后MAP,HR均较诱导前显著下降(P<0.05)。B组患者术中MAP,HR值显著低于A组(P<0.05),拔除喉罩即刻两组MAP,HR差异无显著性(P>0.05)。结论喉罩下全凭七氟醚吸入麻醉对患者的血流动力学的影响较小,适用于妇科宫腔镜手术。

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（ Sp O2）,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.
