Conditions
Keywords
Cardiology, Newborn, Diseases, Congenital Heart Defects, Patent Ductus Arteriosus
Brief summary
To define the characteristics of hemodynamically significant PDA by echocardiography, to investigate the systemic effects of the ductus with cerebral and renal Doppler flow studies, and to determine the oxygen consumption in the cerebral tissue with NIRS in newborns below 32 weeks of age with PDA.
Interventions
