If blood glucose levels are extremely low, the baby may also be given glucose solution via IV. Check for errors and try again. Statistic added: Newer imaging techniques include transorbital sonography (TOS), to evaluate optic nerve sheath diameter as an estimate of cerebral edema post-arrest, although this has been studied in on a very limited fashion to date. In addition to providing therapeutic hypothermia, medical professionals should very closely monitor babies with HIE for abnormalities in heart rate, breathing patterns, temperature, etc. Journal of Neuroradiology.

Its easy to confuse encephalopathy with encephalitis. You can use Radiopaedia cases in a variety of ways to help you learn and teach. Parker, L., & Kenner, C. (2012). How to prevent brain damage due to hypoxic-ischemic encephalopathy (HIE) remains a question that needs an answer due to its serious sequels of neonatal death or severe intellectual, cognitive, and motor disabilities [].Perinatal HIE causes 23% of neonatal deaths [2,3] and affects 1.5-2 per 1000 births in developed countries, but the number affected increases to 26 per 1000 in resource . Small Vessel Disease-Related Dementia: an Invalid Neurovascular Coupling? The cervix is a structure between the uterus and vagina that normally stays closed during pregnancy. Please Note: You can also scroll through stacks with your mouse wheel or the keyboard arrow keys. Hypoxic-ischemic encephalopathy (HIE) and associated conditions(such as cerebral palsy, intellectual and developmental disabilities (I/DD), and seizure disorders) stem from brain damage due to oxygen deprivation.
