Background : The newborn circulation changes from parallel to series and the left and right ventricular output must become equal. In preterm infants especially < 3 days of age, the process was not completed due to inability of the fetal channels (ductus arteriosus and foramen ovale) to close that might effect to haemodynamic status. Echocardiography and Ultrasonic Cardiac Output Monitor (USCOM) is non-invasive bedside cardiac output monitoring methods, which Echocardiography is the gold standard but not easy to performed.
Material : This is a prospective observasional study of LVO measurement using USCOM and Echocardiography. The inclusion criteria: preterm infants (> 32 - < 37 weeks gestational age), birth weight (> 1500 - < 2500 gram) and < 3 days age whose treated in Cipto Mangunkusumo Hospital Neonatal Intensive Care Unit. We did the Echocardiography followed by USCOM’s measurement in less than 1 minutes after. We repeated 2 times in 15 minutes interval for every subject. The Echocardiography was performed by trained Cardiologist and the USCOM was performed by attending Neonatologist. Exclusion criteria: congenital anomaly other than patent ductus arteriosus.
Results : Fourty eights pairs measurement of LVOUscom and LVOEcho from 16 subject were analysed. The LVOUscom and LVOEcho were almost similar (222,78 ± 41,65 and 217,90 ± 73,61 ml/kg/min). The bias, precision, and error percentage of USCOM were 4,87 ml/kg/min, 20,96%, and 36,6% compared to Echocardiography.
Conclusions : USCOM is almost as accurate as Echocardiography in measuring LVO for preterm and/or LBW infants less than 3 days of ages. USCOM can be an alternative device to assess preterm’s LVO. Both of the devices are operator dependent, USCOM is easier to perform and need less training.
