What Is Severe HIE?

What happens if a baby loses oxygen at birth?

Being deprived of oxygen during birth, known as asphyxiation, is a leading cause of infant brain damage, although there are many other possible causes as well.

Brain damage is a serious health concern, and even when it is mild, it can lead to lifelong consequences for the child..

Is hie a disability?

HIE can lead to brain damage, and often to a disability like cerebral palsy. The degree of disability varies by individual and is highly dependent on how long the baby was lacking oxygen. About one out of ten cases of cerebral palsy, of any severity, is caused by HIE.

Is Hie the same as cerebral palsy?

Cerebral palsy is motor dysfunction caused by brain damage; HIE is a form of brain damage that can kill the neurons that transfer motor signals. Cerebral palsy is a disorder that manifests itself in motor difficulties, including muscle spasms (in some cases) and coordination difficulties.

How does Hie happen?

Hypoxic ischemic encephalopathy (HIE) is a type of brain dysfunction that occurs when the brain doesn’t receive enough oxygen or blood flow for a period of time. Hypoxic means not enough oxygen; ischemic means not enough blood flow; and encephalopathy means brain disorder.

Can Hie cause microcephaly?

Acquired microcephaly: Acquired microcephaly occurs when the brain is damaged by an injury like HIE or birth asphyxia. In cases of acquired microcephaly, the head is often a normal size at birth, but as the baby grows, the head and brain begin to appear smaller than is expected.

What causes baby hie?

Hypoxic-ischemic encephalopathy, or HIE, is the brain injury caused by oxygen deprivation to the brain, also commonly known as intrapartum asphyxia. The newborn’s body can compensate for brief periods of depleted oxygen, but if the asphyxia lasts too long, brain tissue is destroyed.

Can hie be cured?

At present, there is no true cure for hypoxic-ischemic encephalopathy (HIE). However there is one treatment, called therapeutic hypothermia, that can reduce the extent of permanent brain damage if given very shortly after birth or the oxygen-depriving incident.

Can babies recover from hie?

Brain injuries from HIE often result in physical disabilities and cognitive impairment. A smaller percentage of babies with HIE fully recover and experience only mild symptoms of neurologic injury.

What are symptoms of hie?

Symptoms and Signs of Hypoxic Ischemic EncephalopathyApgar scores of 3 or lower that last longer than five minutes.Pale or blue skin coloration.Weak or absent breathing patterns.Low heart rate.Acidosis of the blood.Poor muscle tone and weak or absent reflexes.

Can Hie cause autism?

New Research Links Birth Complications (Including HIE) to Increased Autism Risk. Researchers from the Kaiser Permanente health group published the results of a study linking pregnancy complications and birth injuries to an increased risk of autism spectrum disorders (1).

How common is hie?

How common is HIE? Regarding full-term infants, HIE occurs in approximately 3-20 per 1000 live births.
