【摘要】 目的:通过观察单腔气管导管用于儿童单肺通气(OLV)的应用,探讨其在临床应用的安全性。方法:随机选取14例行胸科手术患儿,全麻诱导气管插管后,将单腔气管导管在纤维支气管镜(φ:2.8mm)引导下置入健侧主支气管,并经听诊后确定封堵效果。观察单肺通气前(T1),单肺通气5mim后(T2),单肺通气结束前(T3),单肺通气结束后(T4)的心率HR、血压BP、Sp O2、动脉血气分析、气道压力(PAW)变化。结果:左侧单肺通气5例,右侧单肺通气9例,单肺通气时间40~210mim。全组病例Pa O2:T2较T1明显下降(204±102.2),T3持续小幅下降(202.9±112.3);T4基本恢复至单肺通气前水平(393.6±88.3)。Pa CO2:T2上升(36±4.8),T3持续升高(39.6±5.2),T4降至术前水平(36±5.1);PAW:T2升高(22±2.9),T3维持较高水平(21.4±2.3),T4恢复术前水平(17.9±1.9)。全组病例p H值各时间点数据无明显变化。结论:单腔气管导管能够安全的用于儿童的单肺通气。更多还原

【Abstract】 Objective: by observing the single lumen endotracheal tube application of one-lung ventilation(OLV)in children and its safety in clinical application. Methods:randomly selected 14 children with routine thoracic surgery,after endotracheal intubation of general anesthesia induction, the single lumen endotracheal tube in fiber bronchoscope(φ:2.8 mm) guided into the contralateral primary bronchus, and determine the effect after auscultation.One-lung ventilation(T1), before the observation after 5 mim one-lung ventilation(T2), before the end of single lung ventilation(T3), single lung ventilation(T4), heart rate after HR, blood pressure(BP), Sp O2, arterial blood gas analysis,and airway pressure changes(PAW). One-lung ventilation in 5 cases,Results: the left the right side of the 9 cases of single lung ventilation, 40-210 mim one-lung ventilation time. Incidence Pa O2: T2T1 significantly lower(204 ±102.2), a slight drop in T3last(202.9±112.3); T4one-lung ventilation before back to basic level(393.6 ± 88.3). PaCO2: T2rise(36 ± 4.8), increasing T3(39.6± 5.2), the T4 to preoperative levels(36 ±5.1); Paw: T2(22± 2.9), T3 to maintain higher levels(21.4± 2.3), T4 resume preoperative levels(17.9±1.9). Incidence of p H: each time point data have no obvious changes. Conclusion: single lumen endotracheal tube can be safe for children over the age of 1 with single lung ventilation更多还原
