Maternal hyperglycemia during the peripartum period is highly correlated with fetal hyperinsulinemia and consequent neonatal hypoglycemia. Liberal use of intravenous glucose therapy prior to delivery can potentially cause maternal hyperglycemia, therefore, it is prudent to implement all preventive measures.
This study aims to determine the occurrence of neonatal hypoglycemia with intravenous glucose therapy prior to delivery in maternal diabetes mellitus.
This was a retrospective cohort study of neonates born from diabetic mothers at the University of Santo Tomas Hospital Clinical and Private Divisions from January 1, 2013 to December 15, 2017. Clinical information gathered was divided into maternal and neonatal characteristics. Maternal intravenous fluid use, rate, and duration were noted; maternal and neonatal blood glucose results were obtained.
There were 109 infants of diabetic mothers, of which 105 were delivered as singleton and 4 from twin pregnancies. Neonatal hypoglycemia was present in 14.68%. Comparing the risk factors, there was a higher amount of glucose infused to the mothers whose offspring developed hypoglycemia compared to those without hypoglycemia. Statistically, this did not demonstrate a significant difference. The rate of glucose infusion and frequency of maternal insulin use were similar between the groups. Linear correlation was not evident when the total glucose infused and the rate of intravenous glucose infusion was compared to the neonatal glucose in the first hour of life.
Based on this study, routine administration of glucose-containing intravenous fluid did not influence the incidence of neonatal hypoglycemia. It is recommended that further prospective studies be conducted.
