目的 研究便携式超声心输出量监护仪(ultrasonic cardiac output monitor,USCOM)在肺炎合并心力衰竭患儿的应用及其临床意义.方法 应用USCOM分别测量14例肺炎合并心力衰竭患儿、32例普通肺炎患儿(对照组)的心功能(左心室)相关指标:包括主动脉峰流速、心率、每搏输出量指数、心指数、射血时间及校正后的射血时间.结果 肺炎合并心力衰竭组心率(174±10)次/min明显快于对照组(133±14)次/min(P＜0.05);而主动脉峰流速低于对照组[(1.246±0.234) m/s vs (1.449±0.300) m/s] (P ＜0.05);每搏输出量指数亦低于对照组[(29.357±6.500) ml/m2 vs (40.188 ±5.337) ml/m2](P＜0.05);同时校正后的射血时间明显缩短[(342.560 ±8.219) ms vs (354.430±16.500) ms] (P ＜0.05).结论 USCOM可以准确地测量心输出量,敏感地反映心功能情况,能够对重症肺炎合并心力衰竭患儿进行简单、快捷、准确的评估.

Objective To explore the application of the ultrasonic cardiac output monitor(USCOM) in the children with pneumonia complicated with heart failure.Methods Fourteen children with pneumonia complicated with heart failure were enrolled in the experimental group and thirty-two children with common pneumonia were enrolled in the control group.We used the USCOM to measure the cardiac output indicators,including the aortic peak velocity,heart rate,stroke volume index,cardiac index,ejection time and correcting ejection time.Results The heart rate in the experimental group was faster than that of control group[(174 ±10) beats/min vs (133 ± 14) beats/min,P ＜0.05],the aortic peak velocity in the experimental group was lower than that of control group [(1.246 ±0.234) m/s vs (1.449 ±0.300) m/s,P ＜0.05],the stroke volume index in the experimental group was lower than that of control group [(29.357 ± 6.500) ml/m2 vs (40.188 ±5.337) ml/m2,P ＜0.05],and the correcting ejection time in the experimental group was shorter than that of control group [(342.560 ± 8.219) ms vs (354.430 ± 16.500) ms,P ＜ 0.05].Conclusion The cardiac function monitoring by USCOM is accurate and convenient,and USCOM can provide the accurate evidence for the clinical application.
