摘要
目的:探讨支气管封堵导管在先心病术后小儿NUSS手术麻醉中的应用的可行性。方法:30例先心病术后需行NUSS手术的小儿,随机分成实验组(n=15)和对照组(n=15),实验组在单腔管基础上插入支气管封堵导管,对照组插入单腔气管导管。分别记录单肺通气前、单肺通气1、5、10、15min及单肺通气毕即刻的心率(HR)、平均有创动脉压(MAP)、SPO2及气道压力峰值(PAW)的变化和观察肺萎陷程度。结果:和对照组对比,实验组在单肺通气1、5、10、15min时PAW升高(P<0.05),单肺通气1、5、10min时SPO2下降(P<0.05);实验组术中肺萎陷良好(P<0.05)。结论:支气管封堵导管能为先心病术后小儿NUSS手术的麻醉提供良好的手术视野,且安全简便。
Objective:To discuss the feasibility and safety of the one-lung ventilation with the bronchial blockers in NUSS operation of children alter operation of congenital heart disease(CHD).Methods:A total of thirty children were divided into the group of experimental(n = 15) and the group of control(n =15) at random,the children oi the group o± experimental with the bronchial blockers at the base of single-endotracheal tube,the group of control with single-endotracheal tube.To recorded the heart rate,blood pressure,oxygen saturation by pulse oximeter(spo2) and the airway pressure at before one-lung ventilationd and 1,5,10,15 min after one-lung ventilation and after one-lung ventilation,to observe the pulmonary collapse at the same time.Results:The group of experimental collapse better than the group of control,and PAW at 1,5,10,15 min increases(P <0.05),SP02 at 1,5,10 min lower(P <0.05).Conclusion:the one-lung ventilation with the bronchial blockers provide satisfactory in NUSS operation of children after operation for congenital heart disease(CHD).
