HIE Stages
The three stages of HIE or Hypoxic Ischemic Encephalopathy are generally defined as:
- Stage I – mild HIE
- Stage II – moderate HIE
- Stage III – severe HIE
This 3-stage classification system for HIE was developed in 1976 by researchers Sarnat and Sarnat. Nearly half a century later, it continues to be the most reliable staging system used globally to identify the severity level of the baby’s HIE birth injury and to determine whether the baby qualifies for therapeutic hypothermia to treat HIE.

Stage I: Mild HIE
Stage I, which describes mild conditions of HIE, is generally characterized by the following signs and symptoms of HIE in the baby noticeable immediately after birth:
- Overactive or hyper-alert baby
- Floppy muscles (slightly reduced muscle tone)
- Overly Fussy or irritable baby
- Brisk reflexes to stimulus
- Feeding problems
- Sleeping difficulties
- Crying more frequently than expected
These mild HIE symptoms often resolve in 24 hours or less, but may last longer in some babies. In any case, the medical team should carefully monitor all the Stage I symptoms and make appropriate medical interventions as necessary.
Stage II: Moderate HIE
Stage II describes the moderate level of HIE injury, where the baby may show some or all of the following signs and symptoms:
- Significant muscle weakness (hypotonia)
- Continuous lethargy or sluggishness
- Difficulties in clapping or grasping with hands
- Lower reflexes in response to stimulus
- Difficulties in breathing
- Excessive irritability
- Feeble cries
- Disinterest in sucking
- Apnea (momentary breathing cessation)
Proper diagnosis, monitoring and interventions are critical in case of Stage II or moderate HIE in order to improve the child’s prognosis. Hypothermia therapy should be administered within the first six hours for babies who qualify for this treatment. The first few weeks are crucial for monitoring and medical care for babies with moderate HIE injury.

An MRI should be done after the hypothermia therapy to look for signs of long-term brain damage due to the HIE injury.
Stage III: Severe HIE
Stage III or severe HIE is the most dangerous or life-threatening condition for the newborn baby, which is usually marked by some or all of the following symptoms:
- The baby is in a coma-like stupor
- Unresponsive to physical stimulus
- Serious breathing problems, which may require ventilator
- Poor muscle tone throughout the body (generalized hypotonia)
- Absence of neonatal reflexes (no grasping, swallowing, or sucking)
- Fixed, unresponsive or dilated pupils
- Fluctuating blood pressure
- Irregular heart rate
- Treatment-resistant seizures (progressively increasing)
Severe cases of HIE injury may lead to permanent disabilities, including cerebral palsy, or even the baby’s death. The medical team should immediately administer hypothermia therapy to qualifying babies in this condition, and continue to monitor the baby’s symptoms in order to develop an appropriate care plan.
In addition to the observable signs and symptoms, the medical provider should order diagnostic tests, such as MRI scan to assess the nature and extent of brain damage for appropriate management. Medical treatment and therapy while in the Neonatal Intensive Care Unit (NICU) during the first few hours and days following an HIE insult can reduce the risk and severity of future complications, such as cerebral palsy.
Is Medical Malpractice the Cause of Your Child’s HIE Injury?
Parents whose children are suffering from an hypoxic ischemic encephalopathy (HIE) want and deserve answers as to whether errors by the doctors and nurses during or just after the delivery contributed to their child’s birth injury.
At Miller Weisbrod Olesky, our award-winning cerebral palsy attorneys have represented families all over the United States in their time of need after a birth injury like HIE. We use our skills and expertise to obtain for you and your child a medical malpractice settlement that will help provide specialized medical therapy in order to maximize the quality of life and independence of your child throughout their life.
- Were there signs of birth injury or birth complications during the pregnancy, labor, and delivery process, or presence of risk factors, which were either not recognized or properly treated?
- During the labor and delivery, were there clear indications that the baby was suffering from fetal distress, but appropriate actions were not taken by the maternal fetal specialists, obstetrician or nurses?
- Was there a delay in diagnosis of a likely premature birth that led to later complications, including brain injury?
- Did the medical team fail to order a series of tests to diagnose this birth complication in a timely manner?
- Was the decision to perform a cesarean delivery delayed leading to birth trauma during vaginal delivery or labor?
- Did the neonatal resuscitation team fail to quickly begin important breathing support?
- Should brain cooling (also called “hypothermia therapy”) have been provided to your baby, but the doctors and nurses failed to perform the appropriate tests or ignored the results of the tests?
Our birth injury attorneys have recovered millions of dollars in settlements for families of children that have suffered a birth injury. At no point in our legal intake process will we ask you to pay anything. The medical review of your case and the consultation are free.

Why Should You Talk with the Highly Capable Attorneys at Miller Weisbrod Olesky?

The only way to find out if you have a birth injury case is to talk to a lawyer experienced in birth injury lawsuits. It’s not uncommon that a birth related complication results in a preventable birth injury, including cerebral palsy, but it takes a detailed expert review by a birth injury attorney of the medical records from your child’s birth to determine if the birth injury was the result of medical malpractice.
At Miller Weisbrod Olesky, a team of committed lawyers, nurses and paralegals uses our detailed medical negligence case review process to assess your child’s potential birth injury case. We start by learning more about you and your child and the status of meeting/missing developmental milestones. Then we gather medical records to determine what happened before, during pregnancy. We call in documented and proven medical experts who review your records and let us know if they think medical errors could have caused your child’s injuries.
If we feel medical negligence caused or contributed to wrongful birth in your case, we meet with you to discuss how you can receive compensation from the medical professionals who made the errors. Our birth injury attorneys have recovered millions of dollars in settlements for families of children that have suffered a birth injury.
At no point in our legal intake process will we ask you to pay anything. The medical review of your case and the consultation are free. We only receive payment when you do no matter how long or tough your case is.
