Normal Reference Range for Neonatal Echocardiography

Echocardiography is the main method of bedside examination of neonatal cardiac morphology, which can timely diagnose congenital heart disease and quantitatively assess its severity, but the diagnosis and evaluation process depends on the normal range of neonatal echocardiography.At present, there have been normal reference standards for echocardiography in children and adults at home and abroad, but there is no uniform standard for echocardiographic parameters in newborns, especially premature infants.This study intends to carry out a national multicenter, prospective, observational study to establish the reference range of echocardiography at different time periods after birth in newborns, and stratified according to gestational age, birth weight and gender, to conduct a more accurate hemodynamic assessment of clinically critically ill newborns and guide the treatment of critically ill newborns in real time.
