What Is Hypoxic Ischemic Encephalopathy?

Hypoxic ischemic encephalopathy (HIE), also called birth asphyxia or perinatal asphyxia, is a serious brain injury that occurs when a baby’s brain doesn’t get enough oxygen or blood flow before, during, or shortly after birth.

HIE often results from medical negligence when doctors, nurses, or hospitals fail to properly monitor fetal distress, delay an emergency C-section, or make other preventable mistakes during labor and delivery.

What Causes Hypoxic Ischemic Encephalopathy?

Sometimes, hypoxic ischemic encephalopathy occurs even when doctors and nurses do everything right. Complications during pregnancy or delivery can develop quickly and without warning.

However, some causes of HIE are related to medical malpractice. When medical professionals don’t act quickly or correctly, the lack of oxygen or blood flow can cause severe disability.

Examples of medical malpractice in HIE birth injury cases include:

  • Delayed delivery: In an emergency, a C-section may need to be performed immediately to prevent oxygen deprivation. If the delivery team hesitates or fails to act fast enough, the delay can lead to severe brain injury.
  • Failure to recognize fetal distress: Warning signs like an abnormal heart rate or decreased fetal movement often indicate that a baby isn’t getting enough oxygen. Ignoring or misinterpreting these signs can result in lasting harm.
  • Faulty or misused medical equipment: If resuscitation or oxygen devices fail or aren’t used correctly, it can delay critical treatment and increase the risk of brain damage.
  • Improper use of cooling therapy: Cooling therapy can help limit brain injury if started quickly after birth. Delays in providing this treatment can worsen the outcome for the baby.
  • Mismanaging maternal health problems: Preeclampsia (high blood pressure) in the mother, or low blood pressure during delivery, can lead to HIE, as can issues with the umbilical cord or placenta.

At LawFirm.com, we have registered nurses on staff who can listen to your story and help determine whether medical malpractice may have contributed to your baby’s condition.

“HIE happens when there’s been a lack of oxygen to the baby’s brain for a significant amount of time, usually because the baby’s been in trouble during the labor and we didn’t get them delivered fast enough.”

Can I File an HIE Brain Damage Lawsuit?

You may be able to file an HIE brain injury lawsuit if a doctor or nurse’s mistake during labor or delivery caused your child’s injury.

A hypoxic ischemic encephalopathy attorney can help determine whether medical negligence played a role and guide you through the legal process from start to finish.

Those who typically file hypoxic ischemic encephalopathy lawsuits are:

  • Parents
  • Legal guardians
  • Representatives of the child’s estate

Even if your baby hasn’t received an official HIE diagnosis yet, you may still have legal options. Signs of HIE syndrome may not appear until months or even years after birth, when a child starts missing developmental milestones.

Deadlines for Hypoxic Ischemic Encephalopathy Injury Lawsuits

Every state has laws known as statutes of limitations, which limit how long families have to file a hypoxic ischemic encephalopathy lawsuit.

These time limits can vary depending on where you live and the details of your case. In some states, you may have as little as 1 year to take legal action on behalf of your child.

Once the deadline passes, you may lose your right to pursue compensation, even if medical negligence caused your baby’s injury. That’s why it’s important to speak with an HIE attorney as soon as possible.

At LawFirm.com, our legal partners can review your case for free, explain the filing deadline in your state, and take quick action to protect your family’s rights. Get started with a free case review.

Hypoxic Ischemic Encephalopathy Symptoms

Some hypoxic ischemic encephalopathy symptoms appear immediately after birth, while others may not become noticeable until your child begins to miss developmental milestones.

Common signs of HIE in infants include:

  • A bluish color to the skin, lips, or nails
  • Breathing problems or slow heart rate
  • Difficulty feeding or latching
  • Extreme fussiness or irritability
  • Poor reflexes or sluggish movements
  • Seizures or twitching
  • Weak muscle tone (floppy appearance)

Because birth injury symptoms can vary based on how long the brain was deprived of oxygen and which areas were affected, some babies may appear healthy at first but show signs later in infancy or early childhood.

Early detection and treatment can improve outcomes and limit long-term complications. If you believe your child may have an HIE brain injury, get medical care right away and consider contacting a birth injury lawyer to learn about your legal options.

HIE Treatment Options

While there is no cure for hypoxic ischemic encephalopathy, early treatment can help reduce the severity of brain injury and improve long-term outcomes.

The type of care a baby receives often depends on how quickly the condition is diagnosed and how serious the oxygen loss was.

Common hypoxic ischemic encephalopathy treatments include:

  • Nutritional support: Some babies may need feeding tubes or special nutrition plans if they have trouble swallowing or latching.
  • Physical and occupational therapy: Early intervention programs can help children develop motor skills and improve muscle tone as they grow.
  • Respiratory support: Babies who struggle to breathe may need oxygen, ventilation, or other respiratory assistance to maintain stable oxygen levels.
  • Seizure management: Medications can help control or prevent seizures caused by brain cell injury.
  • Speech and cognitive therapy: As children get older, specialized therapy may assist with communication and learning challenges related to HIE.
  • Therapeutic hypothermia (cooling therapy): Lowering a baby’s body temperature within the first 6 hours after birth can help slow brain damage and improve recovery.

Even with the best medical care, children with HIE often face lifelong challenges that require ongoing treatment and support. If medical negligence caused your child’s condition, you may be able to pursue financial compensation to help cover these costs.

“After birth, our child required resuscitation and cooling therapy. They have a brain injury and Erb’s palsy, which causes muscle tightness and makes them unable to walk. We were unsure how to navigate these difficulties until we found a birth injury law firm.”

HIE Lawsuit FAQs

What is the survival rate for hypoxic ischemic encephalopathy?

The survival rate for hypoxic ischemic encephalopathy (HIE) depends on how severe the oxygen loss was and how quickly treatment began after birth.

The 1-year survival rate for HIE was 84.7% and the 5-year survival rate was 62.9%, according to a 2025 study published in Brain Disorders.

Early treatment, particularly cooling therapy started within 6 hours of birth, has been shown to improve both survival and long-term developmental outcomes.

Can you recover from hypoxic ischemic encephalopathy?

Recovery from hypoxic ischemic encephalopathy depends on how long the brain was deprived of oxygen and how quickly treatment began. Some babies with mild HIE may recover fully, while those with more severe cases may face lifelong challenges.

Find out about recovery by HIE stages:

  • Mild HIE: Many infants recover with few or no long-term effects, especially when treated promptly.
  • Moderate HIE: Some children experience developmental delays, learning difficulties, or mild motor impairments, even with early therapy.
  • Severe HIE: Babies who survive may have lasting neurological conditions such as cerebral palsy, epilepsy, or intellectual disabilities.

Therapies such as cooling treatment, physical and occupational therapy, and ongoing early intervention services can greatly improve a child’s abilities and quality of life.

What is the difference between hypoxic and ischemic brain injury?

Both hypoxic and ischemic brain injuries involve a loss of oxygen to the brain, but they happen in slightly different ways.

  • Hypoxic brain injury occurs when the brain receives some oxygen, but not enough to function properly.
  • Ischemic brain injury happens when blood flow to the brain is completely or partially blocked, cutting off oxygen and essential nutrients.

When these two conditions occur together, the result is called hypoxic ischemic encephalopathy, a serious brain injury that can happen before, during, or shortly after birth.

How is HIE diagnosed?

Doctors use several tests and evaluations to diagnose HIE and determine how severe the brain injury is. Diagnosis typically begins shortly after birth and may involve both physical exams and advanced neuroimaging.

Common HIE diagnostic tools include:

  • Physical exam and Apgar score: Doctors assess the baby’s breathing, heart rate, and muscle tone. Low Apgar scores at 1 and 5 minutes after birth can indicate oxygen deprivation.
  • Cord blood and blood tests: Used to measure pH levels, oxygen, and signs of hypoxia or ischemia in the baby’s system.
  • EEG (electroencephalogram) or EEG monitoring: Measures electrical activity in the brain and helps detect seizures or abnormal brain function.
  • MRI (magnetic resonance imaging) and other neuroimaging: Provides detailed images of brain tissue to detect areas of injury or hemorrhage.
  • Neurologic assessment and Sarnat staging: Helps classify the severity of HIE (mild, moderate, or severe) based on symptoms like muscle tone, reflexes, and alertness.

Newborns with suspected HIE are often admitted to a neonatal intensive care unit (NICU) or children’s hospital, where a pediatric neurology or neonatology team can monitor and treat them.

Is HIE the same as a stroke?

No, HIE and a stroke are not the same, though both involve a lack of oxygen and blood flow to the brain.

HIE occurs when the brain as a whole doesn’t receive enough oxygen and blood, often due to medical malpractice during pregnancy, labor, or delivery. This oxygen loss can cause widespread brain injury.

A stroke, on the other hand, happens when a specific blood vessel in the brain is blocked (ischemic stroke) or bursts (hemorrhagic stroke), causing damage in one localized area.

How can I get help with an HIE lawsuit case?

If you suspect your child’s HIE was caused by medical negligence, an experienced birth injury lawyer can help. They can review medical records, consult experts, and file your claim before any deadlines, allowing you to focus on your child’s care.
