Abstract
Neonatal hypoglycemia is a major source of concern for pediatricians since it has commonly been related to poor neurodevelopmental outcomes. Diagnosis is challenging, considering the different operational thresholds provided by each guideline. Screening of infants at risk plays a crucial role, considering that most hypoglycemic infants show no clinical signs. New opportunities for prevention and treatment are provided by the use of oral dextrose gel. Continuous glucose monitoring systems could be a feasible tool in the next future. Furthermore, there is still limited evidence to underpin the current clinical practice of administering, in case of hypoglycemia, an intravenous "mini-bolus" of 10% dextrose before starting a continuous dextrose infusion. This brief review provides an overview of the latest advances in this field and neurodevelopmental outcomes according to different approaches. Conclusion:To adequately define if a more permissive approach is risk-free for neurodevelopmental outcomes, more researchon continuous glucose monitoring and long-term follow-up is still needed. What is Known: •Neonatal hypoglycemia (NH) is a well-known cause of brain injury that could be prevented to avoidneurodevelopmental impairment. • Diagnosis is challenging, considering the different suggested operational thresholds for NH (<36, <40, <45, <47or <50 mg/dl). What is New: •A 36 mg/dl threshold seems to be not associated with a worse psychomotor development at 18 months of lifewhen compared to the "traditional" threshold (47 mg/dl). •Further studies on long-term neurodevelopmental outcomes are required before suggesting a more permissivemanagement of NH.
