Reference #182 added: Harmon MBA, van Meenen DMP, van der Veen A, et al. The reason for this predilection is not entirely clear, but it has been suggested that the relative immaturity of Purkinje cells (which are normally exquisitely sensitive to ischemic damage) in neonates somehow protects the cerebellar cortex 1. Statistic added: A 2016 Canadian multicenter study utilized a multifaceted quality intervention consisting of education, pathways, local champions and audit-feedback, resulting in improved rates of appropriate neurologic prognostication, but without an increase in survival with good neurologic outcome. 2013;40(3):164-71. 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 .

With placenta previa, however, the placenta attaches to the uterus close to the cervix, which can cause life-threatening bleeding during delivery. These health issues include: If a baby is at risk for hypoglycemia or shows signs of hypoglycemia, blood glucose concentration must be determined within minutes (ideally via lab testing, but with a testing strip later confirmed with lab results if lab results cannot be processed quickly). However there is one treatment, called therapeutic hypothermia, that can reduce the extent of permanent brain damage if given very shortly after birth or the oxygen-depriving incident. Check for errors and try again. In most cases, the placenta connects to the uterus far away from the mothers cervix.
