The aim of the study is to examine whether the use of continuous glucose monitoring (CGM) to guide the clinical management of glycaemic control will result into an increased time in the target glucose concentration. To further examine the efficacy of using CGM the following secondary outcomes in the two groups were assessed: mean glucose values, glucose variability within individuals, percentage of time that glucose values are in hyperglycaemic or hypoglycaemic ranges. Randomized controlled trial recruiting neonates (Birth weight \>1.8kg, Gestation\>36 weeks) with moderate or severe hypoxic ischemic encephalopathy (HIE) following perinatal asphyxia . Neonates will be randomly assigned (1:1) within 6 hours of birth to receive either the intervention with real-time CGM or standard care for 72 hours.
