Intraventricular Hemorrhage of Prematurity, Complications of Prematurity
Cerebral Oxygenation and Autoregulation in Preterm Infants
Premature infants are at high risk for variations in blood pressure and oxygenation during the first few days of life. The immaturity of the premature brain may further predispose these infants to death or the development of…
