摘　　要： 目的 与超声心动图( echocardiography,ECHO)比较,评估超声心输出量监测仪( ultra-sonic cardiac output monitor,USCOM)及电子心力监测仪( electric impedance,ICON)在早产儿心功能监测中的一致性.方法 对所有入组患儿分别于生后第2天和第7天同时使用ECHO、USCOM和ICON进行心功能监测,记录心率(heart rate,HR)、心脏指数(cardiac index,CI).结果 生后第2天,ECHO测得的CI为(3. 26 ± 0. 68)L/(min·m2),USCOM测得的CI为(3. 21 ± 0. 66) L/( min·m2 ),ICON测得的CI为(3. 67 ± 0. 69)L/(min·m2),其平均百分误差分别为27. 9%和42. 3%.生后第7天,ECHO测得的CI为(3. 53 ± 0. 57)L/(min·m2),USCOM测得的CI为(3. 47 ± 0. 59) L/( min·m2 ),ICON测得的CI为(3. 73 ± 0. 67)L/(min·m2),其平均百分误差分别为25. 8%和28. 3%.结论 USCOM与ECHO监测早产儿心输出量时,生后各时间点一致性均良好. ICON与ECHO相比,生后早期监测一致性较差,但出生一周后监测有一定参考价值. Objective To evaluate the consistency of ultrasonic cardiac output monitor(USCOM)and electric impedance(ICON)in cardiac function monitoring in preterm infants compared with echocardiography(ECHO).Methods All enrolled children were monitored with ECHO,USCOM and ICON on the 2nd and 7th day after birth.Heart rate(HR)and cardiac index(CI)were recorded.Results On the second day after birth,the CI measured by ECHO was(3.26±0.68)L/(min·m2),the CI measured by USCOM was(3.21±0.66)L/(min·m2),and the CI measured by ICON was(3.67±0.69)L/(min·m2),with an average percent error of 27.9%and 42.3%,respectively.On the 7th day after birth,the CI measured by ECHO was(3.53±0.57)L/(min·m2),the CI measured by USCOM was(3.47±0.59)L/(min·m2),and the CI measured by ICON was(3.73±0.67)L/(min·m2),with an average percent error of 25.8%and 28.3%,respectively.Conclusion Comparing USCOM with ECHO in cardiac output monitoring of preterm infants,the consistency is good at each time point after birth.Compared with ECHO,ICON has poor consistency in early postnatal cardiac index monitoring,but dynamic monitoring has a certain reference value after one week of birth.
