目的探讨喉罩用于小儿支气管肺泡灌洗术的临床疗效。方法行肺泡灌洗治疗（BAL）患儿111例，采用随机数字表法随机分为静喉罩组（GAL）37例、气管插管组（GAT）37例及面罩组（GAM）37例，记录患儿术中呛咳及肢体运动发生情况、手术时间及肺泡灌洗液回收率，测量麻醉前、纤维支气管镜（FOB）插入气管及灌洗时的平均脉压（MAP）、心率（HR）及血氧饱和度（SpO2）数值。结果GAL组患儿的术中呛咳次数、肢体运动次数、手术时间低于GAT组及GAM组，差异有统计学意义（P＜0.05）；GAL组及GAT组肺泡灌洗液回收率高于GAM组，差异有统计学意义（P＜0.05）；仅GAL组MAP和HR FOB检查前后差异无统计学意义（P＜0.05），GAL组SpO2 FOB检查时较麻醉前高，但在GAT组及GAM组SpO2低于麻醉前（P＜0.05）。结论喉罩用于小儿支气管肺泡灌洗术操作简单，刺激性较小，手术时间短，更为安全有效。

ObjectiveTo approach the clinical effectiveness of laryngeal mask in children bronchoalveolar lavage. MethodsAll pedopatients were divided into three groups: the vein laryngeal mask group(GAL group, 37patients), the tracheal intubation group(GAT group,37patients), and the face mask group(GAM group,37patients) using random number way. Bucking and limbs motion during operation, the operation time, recovery rate of alveolar wash liquid, and the average artery pressure(MAP) and heart rate(HR),and saturation of blood oxygen(SpO2) before anesthesia, while inserting the bronchofibroscope (FOB),and lavage, were recorded and compared between the two groups. ResultsThe number of bucking and limbs motions,and the operation time were all significantly less in the GA L group than those in the other two groups(P＜0.05), the recovery rate of alveolar wash liquid were significant higher than in the GAL and GAT groups than that in GAM group(P＜0.05).The MAP and HR was not significant different only in the GAL group during FOB insertion and lavage (P＞0.05). The SpO2 became high during FOB only in GAL group, while it became lower in the other two groups than that before anesthesia(P＜0.05). ConclusionsLaryngeal mask is a simple technique with less stimulus ,operation time ,and is safer and more effective in children bronchoalveolar lavage.
