Effect of Fasting Time Before Cesarean Section on Neonatal Blood Glucose in Pregnant Women With Gestational Diabetes Mellitus

Second Affiliated Hospital of Wenzhou Medical University300 enrolled

Overview

Objective: To observe the effect of different fasting time on neonatal blood glucose in pregnant women with gestational diabetes mellitus (GDM). Methods: 122 pregnant women with gestational diabetes mellitus were selected from September 2018 to September 2020 in XX Hospital for regular prenatal examination, matching of pregnancy and delivery times, and undergoing elective lower uterine cesarean section to terminate pregnancy. The pregnant women were divided into 5 groups according to their fasting time before operation and whether they were given rehydration on the same day before operation, There were 27 cases in group B (fasting time 12.75 ± 0.48 hours, no rehydration before operation), 20 cases in group C (fasting time 15.65 ± 0.52 hours, no rehydration before operation), 24 cases in group D (fasting time 12.75 ± 0.48 hours, intravenous drip of 5% glucose sodium chloride 500ml at 8:00 on the day of operation), 24 cases in Group E (fasting time 15.65 ± 0.52 hours, intravenous drip of 5% glucose sodium chloride 500ml at 8:00 on the day of operation). The blood glucose of pregnant women within half an hour before operation, the blood glucose of newborns after delivery and the incidence of neonatal hypoglycemia were observed and recorded.
