Insights
Neonatal hypoglycemia, common in at-risk infants, may impact development. This review examines evidence on screening, prevention, and treatment to improve long-term neurodevelopmental outcomes.
Area of Science:
- Neonatal medicine
- Developmental pediatrics
- Endocrinology
Background:
- Neonatal hypoglycemia is linked to adverse childhood development, including visual-motor and executive function deficits.
- It frequently affects asymptomatic, at-risk infants (preterm, SGA, LGA, maternal diabetes).
- Current recommendations include early screening via frequent blood glucose monitoring.
Purpose of the Study:
- To review the latest evidence on screening, prophylaxis, and treatment of neonatal hypoglycemia.
- To assess the impact of these interventions on long-term neurodevelopmental outcomes in at-risk infants.
Main Methods:
- This study is a narrative review of existing literature.
- It focuses on evidence related to interventions for neonatal hypoglycemia and their long-term effects.
Main Results:
- The review synthesizes current data on the efficacy of screening, buccal dextrose gel, infant formula, and intravenous dextrose for neonatal hypoglycemia.
- Uncertainty remains regarding the long-term neurodevelopmental benefits of these interventions.
Conclusions:
- Further research is needed to clarify the long-term neurodevelopmental benefits of screening, prophylaxis, and treatment for neonatal hypoglycemia in at-risk infants.
Abstract:
Neonatal hypoglycaemia is associated with adverse development, particularly visual-motor and executive function impairment, in childhood. As neonatal hypoglycaemia is common and frequently asymptomatic in at-risk babies-ie, those born preterm, small or large for gestational age, or to mothers with diabetes, it is recommended that these babies are screened for hypoglycaemia in the first 1-2 days after birth with frequent blood glucose measurements. Neonatal hypoglycaemia can be prevented and treated with buccal dextrose gel, and it is also common to treat babies with hypoglycaemia with infant formula and intravenous dextrose. However, it is uncertain if screening, prophylaxis, or treatment improves long-term outcomes of babies at risk of neonatal hypoglycaemia. This narrative review assesses the latest evidence for screening, prophylaxis, and treatment of neonates at risk of hypoglycaemia to improve long-term neurodevelopmental outcomes.
