What causes fetal encephalopathy?
The most frequent cause of NE is lack of oxygen to the baby at some point during pregnancy or birth. When oxygen deprivation causes NE, the condition may be referred to as hypoxic ischemic encephalopathy (HIE). Lack of oxygen causes damage to the brain, but it can also affect other internal organs.
What is encephalopathy in a newborn?
Neonatal encephalopathy is a heterogeneous, clinically defined syndrome characterized by disturbed neurologic function in the earliest days of life in an infant born at or beyond 35 weeks of gestation, manifested by a reduced level of consciousness or seizures, often accompanied by difficulty with initiating and …
Is neonatal encephalopathy curable?
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.
How long do babies with HIE live?
Somewhere between 15-20% newborns diagnosed with HIE will die in the first week. From the remainder that survives, 25% will suffer permanent brain damage to various degrees of severity. Brain injuries from HIE often result in physical disabilities and cognitive impairment.
How is neonatal encephalopathy treated?
Following initial resuscitation and stabilization, treatment of HIE includes hypothermia therapy for moderate to severe encephalopathy as well as supportive measures focusing on adequate oxygenation, ventilation and perfusion, careful fluid management, avoidance of hypoglycemia and hyperglycemia, and treatment of …
What are the risk factors for neonatal encephalopathy?
Many factors predispose to the onset of Neonatal Encephalopathy either alone or in a combination including (A) Preconception Risk Factors, (B) Maternal Antepartum/intrapartum comorbidities or events, (C) Placental pathology, (D) Hypoxia-ischaemia, (E) Perinatal infection, (F) Neonatal stroke or thrombophilia, (G) …
What is prenatal encephalopathy?
Perinatal asphyxia, more appropriately known as hypoxic-ischemic encephalopathy (HIE), is characterized by clinical and laboratory evidence of acute or subacute brain injury due to asphyxia. The primary causes of this condition are systemic hypoxemia and/or reduced cerebral blood flow (CBF) (see the image below).
How is neonatal encephalopathy diagnosed?
The diagnosis is typically based on a combination of medical history, physical and neurological exams, laboratory results, and neuroimaging. Many of these tests and studies assess brain injury severity and evaluate the status of the baby’s organ systems. Babies with neonatal seizures are usually evaluated for HIE.
What are risk factors for neonatal encephalopathy?
Is HIE curable?
HIE is, unfortunately, not curable. It can also have varying levels of severity, so treatment options may significantly vary. Fortunately, there are many treatments and therapies that can improve function for children with HIE, as well as ways to manage the condition in the long term.
Can HIE be prevented?
While HIE may not be preventable in all cases, a care team’s response to HIE can make a big difference. Expectant parents may want to ask their doctors how they would respond to HIE if their babies are in distress because of oxygen deprivation.
