Hypoxic ischemic encephalopathy (HIE) is a condition that occurs when the entire brain is deprived of an adequate oxygen supply, but the deprivation is not total. While HIE is associated in most cases with oxygen deprivation in the neonate due to birth asphyxia , it can occur in all age groups, and is often a complication of cardiac arrest .
Neonatal encephalopathy (NE), previously known as neonatal hypoxic-ischemic encephalopathy (neonatal HIE or NHIE), is defined as a encephalopathy syndrome with signs and symptoms of abnormal neurological function, in the first few days of life in an infant born after 35 weeks of gestation.
Hypoxic ischemic encephalopathy has many causes and is defined essentially as the reduction in the supply of blood or oxygen to a baby's brain before, during, or even after birth. It is a major cause of death and disability, occurring in approximately 2–3 per 1000 births and causing around 20% of all cases of cerebral palsy. A 2013 Cochrane ...
Sarnat staging, Sarnat Classification or the Sarnat Grading Scale is a classification scale for hypoxic-ischaemic encephalopathy of the newborn (HIE), a syndrome caused by a lack of adequate oxygenation around the time of birth which manifests as altered consciousness, altered muscle tone, and seizures.

The cause of Joseph’s death was hypoxic encephalopathy, the pathologist determined. Its manner was classified as undetermined.
Perinatal asphyxia can be the cause of hypoxic ischemic encephalopathy or intraventricular hemorrhage, especially in preterm births. An infant with severe perinatal asphyxia usually has poor color , perfusion, responsiveness, muscle tone, and respiratory effort, as reflected in a low 5 minute Apgar score.
Depending on how quickly and successfully the infant is resuscitated, hypoxic damage can occur to most of the infant's organs (heart, lungs, liver, gut, kidneys). One serious complication is a brain injury known as neonatal hypoxic-ischemic encephalopathy. [citation needed]
