ObjectivesTo determine the impact of incorporating dextrose gel in the treatment of neonatal hypoglycaemia (NH) and the role of feeding type in NH outcomes.Study DesignWe conducted a retrospective analysis of 2688 infants >35 weeks' gestation who were screened for NH before and after implementation of a clinical guideline for NH evaluation and treatment. We analysed the proportion of infants who required intravenous dextrose for NH before and after guideline implementation, the change in blood glucose concentrations with gel by feeding type and the odds of successful NH treatment with gel and feeding by feeding type.ResultsFollowing implementation of the guideline, a lower proportion of infants required intravenous dextrose for NH treatment (8.6% (60 infants) before guideline vs. 5.6% (112 infants) after guideline (p=0.007)). The median rise in blood glucose concentration with gel administration in the entire cohort was 0.61 mmol/L (11 mg/dL) (IQR 0.28-1.06 mmol/L (5-19 mg/dL)). Blood glucose concentration of formula-fed infants rose more in response to feeding and gel than breastfed infants (p≤0.0001). Formula feeding was associated with a lower odds of recurrent hypoglycaemia, as defined by requiring a second gel, in a fully adjusted model. Specifically, in infants with a pregel blood glucose of 2.00-2.17 mmol/L (36-39 mg/dL), formula feeding with gel was associated with a lower odds of recurrent hypoglycaemia.ConclusionsDextrose gel is an effective tool in the treatment of NH. An infant's pregel blood glucose concentration may be helpful in guiding decisions around type of feeding provided.© Author(s) (or their employer(s)) 2020. No commercial re-use.
