Abstract:
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.
