Understanding HIE & Its Causes

What Is Hypoxic-Ischemic Encephalopathy (HIE)? Causes of a Preventable Birth Injury

Hypoxic-Ischemic Encephalopathy (HIE) is a serious birth injury that occurs when a baby’s brain doesn’t receive enough oxygen (hypoxia) and blood flow (ischemia) before, during, or just after delivery. This condition can cause permanent brain damage, and in many cases, it leads to long-term conditions like Cerebral Palsy, developmental delays, or seizures.

Unfortunately, HIE is often the result of medical negligence during labor and delivery and parents are rarely told that it was preventable.

What Happens During HIE?

The brain requires a constant flow of oxygen-rich blood to function and develop properly. If that supply is interrupted even for just a few minutes brain cells begin to die, leading to permanent injury. In newborns, HIE often develops when there is fetal distress that isn’t recognized or acted upon in time.

Signs of HIE may include:

  • Low APGAR scores
  • Need for resuscitation at birth
  • Seizures within 24 hours
  • Muscle stiffness or limpness
  • Need for NICU admission and cooling therapy

Common risk points during labor & delivery

What doctors do (simple steps)

Step 1

Stabilize and test

Help with breathing, check blood gases, quick brain/nerve check.

Step 2

Decide about cooling

If baby meets criteria, the team prepares cooling right away.

Step 3

Cooling treatment

Whole-body cooling to 91–93 °F for 72 hours, with close monitoring.

Step 4

Ongoing care

EEG, labs, imaging, seizure care, and regular updates for parents.

What to keep (helps you later)

  • Birth notes and times (decision → delivery, first cry, first seizure).
  • Monitor strips/summaries (heart rate patterns).
  • Blood gas results (pH, base excess, lactate).
  • Treatments given (oxygen, medicines, cooling start/stop times).
  • Names and roles of the staff involved.
HIE — quick numbers in plain language
Topic Typical number / window Plain meaning
Cooling therapy start Within 6 hours after birth If eligible, teams aim to begin early.
Cooling temperature 91–93 °F Lower body temp helps protect the brain.
Cooling duration 72 hours Then warm up slowly with monitoring.
How common is HIE (high-income countries) About 1–3 per 1,000 births Uncommon but serious and time-sensitive.
Cord prolapse (births) About 0.1–0.6% Rare cord problem that can cut oxygen.
Placental abruption (pregnancies) About 0.6–1.2% Placenta separates too early; oxygen can drop.

Top Causes of HIE During Labor and Delivery

Many of the known causes of HIE are preventable with proper monitoring and timely intervention. Here are some of the most common:

  1. Delayed or Failed Emergency C-Section
    When a baby is in distress and not delivered quickly, oxygen can be lost.
  2. Fetal Distress Ignored or Misread
    Abnormal heart rate patterns on fetal monitors are often the first signs of trouble.
  3. Umbilical Cord Problems
    • Cord prolapse (cord drops into birth canal ahead of baby)
    • Nuchal cord (cord wrapped around baby’s neck)
    • Cord compression
  4. Placental Abruption
    The placenta separates from the uterus early, cutting off the oxygen supply.
  5. Uterine Rupture
    Especially in VBAC deliveries, the uterus can tear and cause massive oxygen loss.
  6. Overuse or Misuse of Pitocin
    Excessive contractions can reduce blood flow to the baby.
  7. Infection or Maternal Illness
    Untreated infections or fevers during labor can reduce fetal oxygenation.
  8. Failure to Resuscitate at Birth
    Improper or delayed intervention in the delivery room may allow injury to progress.

Why You May Not Have Been Told

In many hospitals, families are simply told that “sometimes these things happen.” But in reality, many cases of HIE are the result of errors, delays, or poor monitoring and could have been prevented with better care.

If your baby was diagnosed with HIE, required cooling therapy, or now has Cerebral Palsy, it’s time to ask:

Your Questions About HIE Lawsuits?

Why should I contact a lawyer after an HIE diagnosis?

Contacting an HIE birth injury lawyer is the most important step you can take to investigate the circumstances of your child's birth. They can help you understand if the injury was caused by negligence and explain your family's legal right to compensation for your child's lifelong medical needs.

What is the specific role of a hypoxic ischemic encephalopathy lawyer?

The role of a hypoxic ischemic encephalopathy lawyer is highly specialized. Unlike a general practice attorney, they have a deep understanding of the complex medical details of HIE. Their job is to work with world-class medical experts to meticulously review fetal heart strips, delivery notes, and hospital records. They are experts at identifying the exact cause of the oxygen deprivation and building a powerful, evidence-based case on behalf of your child.

How is medical malpractice proven in an HIE case?

Proving negligence requires showing that a doctor or hospital violated the accepted standard of care, and that this failure directly caused the HIE. An experienced HIE medical malpractice attorney accomplishes this by identifying specific errors. This could include a failure to act on clear signs of fetal distress, an unreasonable delay in ordering an emergency C-section, or the misuse of medications like Pitocin. Their investigation focuses on proving the brain injury was not just a tragic accident, but a preventable one.

What should I look for when choosing a birth injury lawyer for an HIE case?

When selecting a birth injury lawyer for HIE, it is crucial to choose a firm, like ours, with a proven track record in these specific cases.
