Newborn Plasma Glucose Concentration Nadirs by Gestational-Age Group

Kaiser et al, Neonatology, 2018

Abstract

Background: The glucose concentrations and times to nadir for newborns of all gestational ages when intrapartum glucose-containing solutions are not routinely provided are unknown.

Objective: To characterize and compare patterns of initial glucose concentration nadirs by gestational-age groups.

Methods: A cross-sectional cohort study of 1,366 newborns born in 1998 at the University of Arkansas for Medical Sciences, appropriate for gestational age, nonasphyxiated, nonpolycythemic, and not infants of diabetic mothers, were included.

Conclusion: Plasma glucose nadirs occurred at different times among gestational-age groups during the early postnatal period as follows: ELGAN < PT < LPTFT. In order to potentially prevent low glucose concentrations at the time of the nadir, exogenous glucose should be provided to all newborns as soon as possible after birth.
