Background: The incidence of congenital heart disease is 8-10 /1000 live birth in different parts of the world. Early detection of major critical congenital heart defects might improve the outcome of new-born babies. Echocardiography is mainly used as diagnostic tool rather than screening tool due to cost effectiveness. Thus pulse oximetry, non-invasive easy to perform stays as main screening tool for diagnosis of critical congenital heart disease in newborn.
Methods: Prospective study conducted in Neonatal unit in Chennai Medical College Hospital & research centre over a period of one year. A total of 430 asymptomatic newborn delivered were screened with pulse oximetry at 1 hour and 24 hours after birth. All positive newborns were screened with echocardiography.
Results: Out of 430 newborns screened, 5 newborns had saturation
