Abstract

Cerebral Palsy Free Radical Generation Hypoplastic Left Heart Syndrome NMDA Receptor Perinatal Asphyxia
Perinatal hypoxia ischemia is the most common cause of neurologic disease during the neonatal period. Hypoxic ischemic encephalopathy (HIE), is associated with a high mortality and morbidity rate, including cerebral palsy, mental retardation, and seizures [1]. The incidence of perinatal asphyxia is about 1.0–1.5% in most centers and is usually related to gestational age and birth weight. It occurs in 9.0% of infants less than 36 weeks’ gestation and in 0.5% of infants more than 36 weeks’ gestation [2, 3]. The etiology of perinatal HIE includes those circumstances that can affect the cerebral blood flow in the fetus and newborn compromising the supply of oxygen to the brain. They may develop antepartum (20%), intrapartum (30%), antepartum and intrapartum (35%), or postpartum (10%) [4].
