摘要
目的观察改良型一次性无菌可控单侧支气管封堵导管(BBs)在胸腔镜下小儿漏斗胸矫正术(Nuss手术)中的应用效果。方法 37例择期行漏斗胸矫正术的患儿,随机分组:BBs组,插入改良型一次性无菌可控单侧支气管封堵导管(17例);SLT组,插入单腔气管导管(20例)。分别记录麻醉前、人工气胸前、人工气胸5、10、20min以及闭胸后血压(BP)、心率(HR)、心电图(ECG)、脉搏血氧饱和度(SpO2);记录上述时间点的呼吸频率(RR)、潮气量(TV)、气道压(PAW)的变化;观察术中肺萎陷程度,术后声嘶、咽痛发生率。结果与SLT组比较,BBs组术中肺萎陷良好,术野暴露满意(P<0.01),SLT组HR在人工气胸10min时点高于BBs组(P<0.05)。结论改良型一次性无菌可控单侧支气管封堵导管能为胸腔镜下小儿漏斗胸矫正术提供满意的操作视野,操作简便,术中呼吸、循环稳定。
Objective To assess the feasibility and safety of the one-lung ventilation with the improved disposable unilat- eral bronchial blockers（BBs） in Nuss operation. Methods Thirty-seven children age from 4 to 12 were randomized divided into improved unilateral BBs group（group BBs） and single-lumen endotracheal group （group SLT）. The blood pressure（BP） ,heart rate（HR） and oxygen saturation by pulse oximeter（ SpO2 ） were recorded before artificial pneumothorax,5,10,20min after artifi- cial pneumothorax and after closed chest. The pulmonary collapse extent and incidence of postperative hoarseness were also ana- lyzed. Results The pulmonary collapse extent were so much the better in group BBS than that in group SLT（ P 〈 0. 01 ）. Com- pared with before artificial pneumothorax, there were significant increases in ttR at lOmin after artificial pneumothorax （P 〈 0. 05） ,and HR w~ significantly higher in the group SLT than that in the group BBs at 10min after artificial pneumothorax （P 〈 0. 05）. Conclusion The one-lung ventilation with the improved disposable unilateral bronchial blockers provide satisfactory oper- ating field in Nuss operation.
