Words cannot describe the joy you feel when you see a new addition to your family. But sometimes, unexpectedly, these little ones can develop some health problems. Today, we are going to talk about a condition that can affect newborns, a bit serious, but one that we all need to be aware of. That is HIE, or hypoxic-ischemic encephalopathy.
What is HIE (Hypoxic-Ischemic Encephalopathy)? Let's understand it exactly.
Simply put, HIE (Hypoxic-Ischemic Encephalopathy) is a brain injury caused by a lack of oxygen and blood supply to the brain. Just think, like every organ in our body, the brain also needs oxygen and nutrients to function. These are delivered to the brain through the blood. If this supply is disrupted in any way, brain cells begin to be damaged. This is what HIE is.
This condition most often affects newborns , especially if there are complications during delivery. However, sometimes older children and adults can also develop HIE if there is a serious respiratory problem, such as drowning .
The most important thing is that HIE is a serious, potentially life-threatening condition . So if you think your child is having symptoms of HIE, you should seek medical advice immediately.
You may have heard your doctor use other names for this HIE condition. For example:
- Birth asphyxia
- Neonatal encephalopathy
- Perinatal hypoxia
No matter what name you call this, it's the same situation.
Are there different types of HIE? How do you assess the severity of the condition?
Yes, doctors classify HIE according to the child's prognosis. These are mainly divided into three categories : mild, moderate, and severe . This classification can determine how the child's nervous system will be affected.
But remember, even if HIE is mild, it is a medical emergency . Because prompt treatment is essential to prevent life-threatening complications. The doctor will be able to give you the best explanation for your child's condition. Then you can make up your mind and move forward.
How common is this condition?
According to statistics, HIE affects between 1 and 6 out of every 1,000 babies born . Even in a country like the United States, about 9,000 to 12,000 newborns face this condition every year. Although it is difficult to find exact statistics in Sri Lanka, this is not a condition that can be ignored.
What are the symptoms of HIE? How about in a newborn baby?
If a newborn has mild or moderate HIE, they may experience symptoms such as:
- The body is either limp and lifeless (`hypotonia`) or stiff and tense (`hypertonia`) .
- Difficulty drinking milk.
- Always showing a tired attitude.
- Constant crying for no reason, restlessness.
- Crying weakly.
- A pale, blue, or grayish color (`cyanosis`) to the skin, fingertips, and lips.
If HIE is severe, symptoms are more severe:
- There is almost no response even if you touch it or make a sound.
- Very weak reflexes.
- Abnormal breathing patterns (e.g., rapid breathing, shortness of breath).
- Irregular or very slow heartbeat.
- Seizures .
- Loss of consciousness.
Important: If your child shows any of these symptoms, take them to the nearest hospital or call 911 immediately . Even if HIE seems mild, it is an emergency. Prompt treatment is the most important thing.
What are the causes of HIE?
The main cause of HIE is a lack of oxygen and blood supply to the brain. There are several ways this can happen.
HIE can occur during fetal development in the womb due to:
- Abnormal development or function of the fetal heart or lungs.
- The mother has an infection (such as toxoplasmosis or CMV).
- Excessive increase or decrease in the pregnant mother's blood pressure.
- Decreased oxygen levels in the pregnant mother's blood.
If there are any complications during pregnancy or childbirth, the baby is at higher risk of developing HIE. For example:
- The umbilical cord, which comes out of the vagina before the fetus is born (`cord prolapse`).
- Compression of the umbilical cord or cessation of blood flow to it.
- Placental abruption.
- Uterine rupture.
- Placenta previa (covering the cervix).
Causes of HIE (difficulty breathing) in older children and adults include:
- Heart rhythm disorders (`Arrhythmia`).
- Suffocation (e.g. drowning, strangulation - `asphyxiation`).
- Overdose of drugs or medication.
- Poisoning (e.g. mercury poisoning).
- Going into shock.
Who is at increased risk of HIE?
A newborn baby may be at increased risk of HIE if:
- Being born with a low birth weight .
- Contamination of the vaginal fluid.
- Delayed fetal development (especially incomplete development of some organs, such as the lungs).
A pregnant mother is at increased risk of complications during childbirth, with conditions such as:
- High blood pressure during pregnancy (`Preeclampsia`).
- Gestational diabetes.
- Prolonged labor.
- Drug use.
What are the possible complications of HIE? Are these dangerous?
HIE is a very serious condition, possibly even fatal. In addition, the permanent damage to the brain can lead to a variety of long-term complications. Some of them are:
- Developmental delays : Delays in things like talking and walking.
- Growth problems.
- Hearing or vision impairment.
- Cognitive function issues, intellectual disability .
- Difficulty concentrating.
- Epilepsy .
- Cerebral palsy .
- Frequent infections.
Many of these complications don't appear right away. They may only appear when your child starts school. If your child isn't meeting developmental milestones for their age, or is having trouble learning in class, see a doctor right away.
How do doctors accurately diagnose HIE?
Because HIE is a medical emergency, doctors are very careful about the signs of the condition before and after the baby is born. This is to make sure that the baby's brain is getting enough oxygen and blood. If there is any difficulty during the birth, doctors are prepared to treat the condition before the baby is officially diagnosed.
To diagnose HIE, a doctor will perform a complete physical exam. They will look for symptoms and order several tests to confirm the diagnosis.
For HIE in newborns, these tests can be done before and after the baby is born:
- Fetal heart monitoring.
- A placental blood test.
- Newborn baby health assessment ( `Apgar score` ).
- Testing the blood and gas levels in the umbilical cord.
- Imaging tests such as `Ultrasound` or `MRI` (Magnetic Resonance Imaging) .
- EEG (Electroencephalogram) test (to measure the electrical activity of the brain).
Additional blood tests help doctors understand how HIE is affecting the child's other organs.
What are the treatments for HIE? (Treatment)
Doctors treat HIE in the following ways:
- Cooling the child's body (therapeutic hypothermia) and then returning it to normal temperature can help prevent further damage to the brain.
- While the child is in the hospital , EEG is used to monitor for seizures, and medication is given to prevent seizures.
- Improve blood and oxygen flow to the brain, and treat the underlying cause with supportive care (e.g., supplemental oxygen through a face mask or nasal cannula).
If complications arise as the child grows, additional support may be needed. This includes:
- Physical therapy or occupational therapy.
- Speech therapy.
- Early childhood education programs.
- Assistive devices such as glasses or hearing aids.
Can there be side effects from the treatment?
Seizure medications can have some side effects. These vary depending on the type of medication being given. Before starting treatment, talk to your child's doctor about these side effects and what symptoms to look out for. ``Therapeutic hypothermia`` (treatment to cool the body) can also cause side effects, such as low blood platelets.
How long will it take for the baby to recover after treatment?
Babies with only mild symptoms and no brain damage usually recover completely within two weeks. However, if the condition is severe, lifelong complications can occur, requiring long-term management.
If my baby has HIE, what should I expect? What is the outlook?
The severity of the HIE condition determines the child's future. Research suggests that between 20% and 50% of babies with HIE die . Also, between 25% and 60% develop long-term neurological disorders or learning disabilities, such as cerebral palsy or epilepsy .
However, in some cases, HIE can be completely cured. The sooner HIE is treated and brain damage is prevented, the better the outcome. However, we must understand that not every baby will fully recover.
If HIE is severe, the baby's life expectancy may be shortened. A baby with severe brain damage may die in infancy or early childhood. Mild HIE usually does not affect life expectancy. Moderate HIE may or may not affect life expectancy. Most babies with mild and moderate HIE have a normal life expectancy. Supportive treatments are available to minimize life-threatening consequences.
Are there ways to prevent HIE?
Unfortunately, HIE cannot always be prevented.
However, you can reduce your risk of developing HIE by getting regular checkups during pregnancy . Your doctor will give you advice on how to stay safe and maintain good health. However, no matter how healthy you are during pregnancy, HIE can still occur.
Also, controlling drug use is very important to prevent complications that can affect you and your baby.
For older children and adults, you can help prevent HIE by taking safety precautions before engaging in potentially dangerous activities. For example, if you are going swimming, only swimming where there is a lifeguard can help prevent drowning.
What time should I see a doctor?
If your child is not meeting developmental milestones for their age, or if they are showing signs of complications as they grow, see your child's doctor. If your child is having difficulty breastfeeding, see a doctor.
When should you go to the Emergency Treatment Unit (ETU) ?
If you, your child, or someone you know has any of these HIE symptoms, call 911 immediately and go to the nearest emergency room:
- Difficulty breathing.
- A seizure.
- If the skin appears pale, blue, or gray.
- Loss of consciousness (fainting).
What questions should I ask the doctor?
You can ask your doctor questions like these:
- How serious is HIE?
- Is my baby's brain damaged?
- What complications should I watch out for?
- Are there any side effects of the treatment?
- When will my child be able to leave the hospital?
- When should I come next to monitor my child's health?
Finally, a little take-home message for parents
I understand how scared and anxious a mother or father feels when they learn that a newborn baby has HIE (Hypoxic-Ischemic Encephalopathy). You can feel very helpless as the medical team works hard all day to make sure that the baby's brain is getting enough oxygen and blood.
During this time, your doctor will keep you updated on your baby's condition . They are there to answer any questions you may have. Also, surround yourself with a strong support group, such as your family and friends, to help you through this challenging experience. If necessary, talking to a mental health counselor can also be a great help. Remember that you are not alone.
