无创心输出量监测在新生儿中的应用

Application of noninvasive cardiac output measurement in neonates

心输出量监测是危重新生儿尤其血流动力学不稳定患儿(如新生儿重症感染、败血症休克、多器官功能衰竭、先天性心脏病等)抢救管理中非常重要的内容,监测方法有有创测量、无创测量以及穿戴式或移动式动态测量等。目前临床上实时、连续无创监测新生儿心输出量多采用超声心输出量监测仪技术。通过监测心输出量,可较准确判断心功能及体循环灌注的情况,对评估病情、指导临床用药及判断预后有重要意义。

Cardiac output measurement is a very important content in the rescue management of critically ill neonates, es- pecially in patients with hemodynamic instability, such as neo- natal severe infection, septic shock, multiple organ failure, con- genital heart disease, etc. The monitoring methods include in- vasive measurement, noninvasive measurement and wearable or portable dynamic measurement, etc. The current clinical non- invasive continuous measurement of neonatal cardiac output mainly adopts ultrasonic cardiac output monitor （USCOM） technique. By monitoring the cardiac output, we can accurately estimate the patient＇ s cardiac function and systemic perfusion, which has important significance in patient＇ s condition assess- ment, clinical medicine guidance and prognosis judgement.
