This week, in our continuing surveys of various kinds of birth injuries, we are taking a closer look at hypoxic ischemic encephalopathy (HIE), an injury that occurs when the infant’s brain is deprived of oxygen. HIE can lead to developmental issues or death; according to Medscape, HIE causes 840,000 neonatal deaths annually–23% of all neonatal deaths worldwide.
Symptoms of HIE vary based on the severity of the condition.
Mild cases of HIE will typically resolve themselves within 24 hours, but symptoms include “transient behavioral abnormalities, such as poor feeding, irritability, or excessive crying or sleepiness,” according to Medscape.
Infants with moderately severe cases of HIE will exhibit more symptoms: the infant will be lethargic and have significant hypotonia, a condition in which the infant’s low muscle tone reduces his muscle strength, and will likely suffer seizures within the first 24 hours after his birth. Additionally, his grasping, Moro reflex (a reflex present in all healthy infants that occurs when the infant feels as if he is falling), and sucking reflexes can be sluggish or absent altogether. This said, full recovery in moderately severe cases of HIE is possible, says Medscape.
Finally, infants with severe HIE are noted to have more frequent generalized seizures that increase in frequency during 24-48 hours after their onset. These seizures “can be delayed and severe and may be initially resistant to conventional treatments.” As the injury progresses, the seizures will subside, and other symptoms will present themselves. Medscape says that a “stupor or coma is typical,” and the infant will likely suffer from irregular breathing, hypotonia, a lack of neonatal reflexes, poor ocular motion, and irregular heart rate and blood pressure. Death from cardiorespiratory failure is also a possibility in cases of severe HIE.
Managing HIE consists mostly of supportive treatment after the initial resuscitation and stabilization. Treatments include perfusion, a stimulation of the body’s process of delivering blood to a capillary bed in its biological tissue, and blood pressure management; avoidance of hypoglycemia and hyperglycemia; treatment of seizures; and avoidance of hyperthermia (elevation of the body temperature). On the other hand, hypothermia therapy, a process in which the infant’s body temperature is kept at a temperature of 91.4 to 92.3 degrees Fahrenheit for approximately 72 hours before slowly being rewarmed, can be helpful for infants suffering from moderate to severe HIE.
