Early prediction of hypoxic ischaemic encephalopathy in newborn infants in a resource-limited setting

Abstract

Hypoxic ischaemic encephalopathy (HIE) after birth is an important cause of neonatal morbidity and mortality, particularly in resource-limited regions. Therapeutic hypothermia initiated within the first 6 hours of life, in settings that can offer neonatal intensive care, is a therapy that can reduce death or severe disability in newborn infants with moderate or severe HIE. Therapeutic hypothermia has not been shown to be safe or effective in low-resource settings where neonatal intensive care is not available; however, there are situations such as in some centres in South Africa, where limited neonatal intensive care (NICU) is available against a background of moderate neonatal mortality rates, relatively low socio-economic conditions and limited capacity for long-term follow-up. In such settings, accurate case definition and early prediction of HIE and outcome may assist with the appropriate allocation of resources. The amplitude-integrated electro-encephalogram (aEEG) is an ideal tool to use for prediction of outcome and the need for cooling, but it’s availability is limited, particularly at primary and secondary hospitals.
