==[[Perinatal asphyxia overview|Overview]]==


'''Perinatal asphyxia''' is the medical condition resulting from deprivation of [[oxygen]] ([[Hypoxia (medical)|hypoxia]]) to a newborn infant long enough to cause apparent harm. It results most commonly from a drop in maternal [[blood pressure]] or interference during [[childbirth|delivery]] with blood flow to the infant's [[brain]]. This can occur due to inadequate [[circulatory system|circulation]] or [[perfusion]], impaired respiratory effort, or inadequate [[Ventilation (physiology)|ventilation]]. Perinatal asphyxia happens in 2 to 10 per 1000 newborns that are born a terme.
==[[Perinatal asphyxia historical perspective|Historical Perspective]]==


An infant suffering severe perinatal asphyxia usually has poor color ([[cyanosis]]), perfusion, responsiveness, muscle tone, and respiratory effort, as reflected in a low 5 minute [[Apgar score]]. Extreme degrees of asphyxia can cause [[cardiac arrest]] and death. If resuscitation is successful, the infant is usually transferred to a [[neonatal intensive care unit]].
==[[Perinatal asphyxia classification|Classification]]==


Hypoxic damage can occur to most of the infant's organs ([[heart]], [[lung]]s, [[liver]], [[gut]], [[kidneys]]), but [[brain damage]] is of most concern and perhaps the least likely to quickly and completely heal. In severe cases, an infant may survive, but with damage to the brain manifested as [[developmental delay]] and [[spasticity]].
