Q: What is hypoxic ischemic encephalopathy (HIE)? How is HIE treated?
Hypoxic Ischemic Encephalopathy (HIE), also known as ‘birth asphyxia,’ is a dangerous and permanent neonatal brain injury. HIE occurs due to oxygen deprivation and/or compromised blood flow to the brain. When this happens, brain cells die off in a cascade reaction, causing widespread brain damage.
What Health Issues Does HIE Cause?
HIE is a brain injury that often causes a child to have permanent brain damage and conditions such as the following:
- Seizure disorders
- Cerebral palsy (CP)
- Intellectual disabilities
- Developmental delays
- Learning Disabilities
- Speech and hearing problems
- Motor disorders
- Periventricular leukomalacia (PVL). HIE usually involves damage to the basal ganglia, cerebral cortex or watershed regions of the brain, but it sometimes includes PVL.
Treatments for HIE
Traditionally, management of HIE has been supportive care. This includes:
- Mechanical ventilation- a machine temporarily helps the baby breathe and controls the oxygen and carbon dioxide levels in the baby’s blood
- Treatments that help maintain adequate blood flow to the baby’s brain
- Control of seizures through anti-seizure medications
- NICU care and care from specialty doctors
Recently, a new therapy called hypothermia (brain cooling) has been used to help treat HIE. Hypothermia treatment must be given within 6 hours of the time the baby experienced the oxygen-depriving insult, which usually means it must be given within 6 hours of birth. Hypothermia treatment has been shown to halt almost every damaging process that starts to occur when the brain is significantly deprived of oxygen. The treatment can prevent a baby with HIE from developing cerebral palsy or the baby may have a less severe form of CP.
Brain Cooling Treatment for HIE
In brain cooling therapy, a cooling cap is applied to the baby’s head or the baby is laid on a cooling mat. A machine circulates cold water through the cap or mat in order to cool the baby’s core body temperature. This is done for 72 hours and then the baby is warmed back to normal temperature. By lowering the baby’s temperature, the metabolic rate slows, allowing cell recovery over a longer period of time, avoiding further damage that can occur if normal oxygenation or blood flow is restored too quickly to injured cells.
Timing is very important when using hypothermia treatment. The most favorable outcomes are seen when brain cooling is started as soon as possible after the birth injury occurs, preferably within 6 hours of birth. The more severe the brain insult, the sooner the treatment should be started. Hypothermia treatment for HIE also requires that the baby be at least 36 weeks gestation.
