Echocardiographic assessment of blood flow volume in the superior vena cava and descending aorta in the newborn infant

Background:Clinical methods of assessing adequacy of the circulation are poor predictors of volume of blood flow in the newborn preterm. Doppler echocardiography can be used to assess perfusion at various sites in the circulation.Objective:To assess repeatability of measurement of volume of superior...

Zusammenfassung:	Background:Clinical methods of assessing adequacy of the circulation are poor predictors of volume of blood flow in the newborn preterm. Doppler echocardiography can be used to assess perfusion at various sites in the circulation.Objective:To assess repeatability of measurement of volume of superior vena caval (SVC) and descending aortic (DAo) flow.Design:SVC and DAo flow volume were assessed four times in the first 48 h of postnatal life in a cohort of preterm (
