Hypoxic Ischemic Encephalopathy and Seizures - Oren Zarif - Hypoxic Ischemic Encephalopathy

If your child has experienced an episode of significant hypoxic ischemic encephalopathic (HIE), you've likely already heard of seizures. The severity of the hypoxia-ischemia-induced seizures depends on how severe the HIE is. Seizures also occur in infants with mild, moderate, or severe HIE. Seizures increase with severe hypoxia-ischemia, but a longer duration of the ischemic insult results in greater seizure activity. Seizures are associated with adverse neurodevelopmental outcomes and may require additional treatment. The effects of repeated seizures on the developing brain have been well documented, and EEG techniques are needed to monitor the occurrence of seizures.

Treatment options for HIE depend on how severe the symptoms are, and the extent of the brain damage. Some children with HIE have a life expectancy comparable to that of children with mild cerebral palsy. A baby with HIE may have feeding difficulties and other symptoms of organ dysfunction. Although the symptoms and outcome of the disease can vary, the most important treatment for HIE is prevention and awareness. While hypoxic ischemic encephalopathy is a rare complication, it can lead to permanent disabilities, such as Cerebral Palsy, and other severe medical complications.

The incidence of hypoxic ischemic encephalomyelitis (HIE) is 1.5 per 1000 live births in the United States. Infants with HIE may experience permanent brain damage, including cerebral palsy and epilepsy. Neuroimaging is important in estimating the risk of adverse neurodevelopmental outcome for the child. Once diagnosed, neuroimaging will help determine whether the condition has progressed.

If your child experiences seizures or other symptoms of encephalopathy, the doctor may recommend an MRI to determine the etiology and prognosis. A head ultrasound is also helpful to determine hemorrhage or ventriculomegaly. In case of an infant with hypoxic ischemic encephalopathy, this procedure is not recommended due to high radiation doses.

Although heart rate variability (HRV) is a biomarker for acute brain injury in hypoxic ischemic encephalopathy, the results of current studies are inconsistent. More research is needed to establish a better understanding of how HIE works and how to intervene with treatments. The current study sought to systematically review the relationship between HIE severity and HRV, allowing us to better anticipate the outcomes of these treatments.

HIE occurs during labor and causes brain damage and disability, depending on the length of time the brain is deprived of oxygen. The extent of the damage varies from child to adult, and the time and location of the oxygen deprivation. In most cases, children affected by HIE will experience minor symptoms to permanent disability. And if you're worried about the risks, a good idea would be to contact a doctor and get tested.

A neonate with HIE will require immediate medical care. The most common method of treatment is therapeutic hypothermia, which is the standard treatment for this condition. Neurophysiologic monitoring and preservation of normal homeostatic mechanisms should be part of the neonate's treatment. MRI results are helpful in assessing prognosis, etiology, and treatment. If hypothermia is able to prevent or delay adverse effects, it should be administered.

Treatment for HIE includes therapeutic hypothermia, a process wherein a baby's body and brain are cooled. Therapeutic hypothermia slows down the cascade effect and minimizes the damage to the brain. Although the effects of hypoxia are permanent, treatments may be beneficial in managing symptoms and improving functioning. The condition may require lifelong care. Your baby should receive therapy as soon as possible after birth.

Prenatal risk factors include maternal hypotension, infertility treatment, and thyroid disease. Twenty-four percent of cases occur when both antepartum and intrapartum risk factors are present. During pregnancy, antepartum risk factors include a high maternal fever and a prolonged reduction of cerebral blood flow. However, the history of antenatal risk factors and placental pathology should be carefully evaluated.
