喉罩连接三通接头在小儿支气管肺泡灌洗术中的应用

摘要

目的 观察喉罩连接三通接头在小儿支气管肺泡灌洗术( BAL)中的应用效果.方法 行BAL的患儿38例,年龄2～13岁,随机分为三组:喉罩组(L组,n=14)和气管插管组(T组,n＝12)在全麻快速诱导后分别插入喉罩和气管导管,成功后连接三通接头,采用吸入全麻;面罩组(M组,n=12)采用静脉全麻,间断吸入七氟醚.观察患儿MAP、HR和SpO2变化,以及术中呛咳、体动发生情况.结果 M组手术时间和麻醉时间均长于L组和T组(P＜0.01).纤支镜通过隆突和灌洗时M组MAP和HR显著高于麻醉前,且明显高于L组和T组(P＜0.01);SpO2明显降低(P＜0.01).与M组比较,纤支镜插入气管后L组和T组SpO2明显升高(P＜0.01).结论 喉罩连接三通接头全麻应用于小儿BAL,经过平稳,保证充分氧供.%Objective To investigate the feasibility and safety of laryngcal mask airway(LMA) with union lee during pediatric bronchoalveolar lavage (BAL). Methods Thirty-eight children undergoing BAL were divided into three groups: LMA group(group L, n＝14), trachea tube group (group T, n=12) and mask group (group M, n= 12). All the patients received intravenous anesthesia and intermittent sevofluranc inhalation. Hemodynemics, SpO2; , coughing and body movement were recorded in each group. Results The operation time and anesthesia time were longer in group M than in group L and group T(P<0. 01). MAP and HR in group M were higher and SpO2 was lower than haseiine and than those in group L and group T when the fibrotic bronchoscopy reaching carina and during iavage. SpO; in group L and group T increased after bronchoscopy insertion. Conclusion It will provide a safe and stable condition for BAL in pediatric patients when using LMA and union tee
