Management of Hyperglycemia in Neonates

Initial Assessment and Measurement

Blood glucose measurements should preferably be performed using blood gas analyzers for the most accurate results in neonates 1, 2, 3
Handheld glucose meters have limitations in neonates due to factors such as high hemoglobin levels and high bilirubin levels 3, 4
Hyperglycemia in neonates is commonly defined as blood glucose level exceeding 10 mmol/L (180 mg/dL) 1, 3

First attempt to control hyperglycemia by reasonable adaptation of the glucose infusion rate 1, 3
For term neonates, target glucose infusion rate should be 2.5-5 mg/kg/min (3.6-7.2 g/kg/day) on day 1 and 5-10 mg/kg/min (7.2-14.4 g/kg/day) on day 2 onwards 5, 6
For preterm neonates, target glucose infusion rate should be 4-8 mg/kg/min (5.8-11.5 g/kg/day) on day 1 and 8-10 mg/kg/min (11.5-14.4 g/kg/day) on day 2 onwards 5, 6
In case of acute illness such as infection or sepsis, temporarily reduce to day 1 glucose infusion rates 5, 6

If hyperglycemia persists with repetitive blood glucose levels >10 mmol/L (180 mg/dL) despite adjustment of glucose infusion rate, initiate insulin therapy 1, 3
Use insulin at a low starting dose to avoid hypoglycemia 1, 3

Hyperglycemia >8 mmol/L (145 mg/dL) should be avoided in neonatal ICU patients as it is associated with increased morbidity and mortality 1, 3
Repetitive and/or prolonged hypoglycemia ≤2.5 mmol/L (45 mg/dL) should be avoided as it can lead to adverse outcomes 5, 4
Insulin therapy in preterm newborns can effectively treat hyperglycemia but increases the risk of hypoglycemia 1, 3

Avoid aggressive insulin therapy that may lead to hypoglycemia; start with low doses 1, 3
