Objective: To study the maternal blood glucose management of gestational diabetes mellitus during the labor and relationship of maternal blood glucose in labor and neonatal blood sugar.
Methods: A prospective study on maternal blood glucose monitoring and control during labor was carried in 40 pregnant women with abnormal glucose metabolism. We adjusted maternal blood glucose by low-dosage constant insulin drop during labor.
Results: Maternal blood glucose in labor arranged between 3.8 approximately 11.2 mmol/L, and low-dosage constant insulin drop was used in 17 cases (42.5%). The neonatal blood glucose was (4.0 +/- 1.5) mmol/L following delivery and (3.9 +/- 1.0) mmol/L at 24-hour postpartum. There were 2 cases with neonatal hypoglycemia. The neonatal blood glucose of the rest 23 cases was (4.2 +/- 1.5) mmol/L, and (3.9 +/- 1.0) mmol/L at 24-hour postpartum, and 1 case with neonatal hypoglycemia. There was no the difference of the blood glucose level of newborns between mothers with abnormal glucose metabolism and the normal pregnant women.
Conclusion: It is necessary to monitor and control the blood glucose level by low dose constant insulin during labor in pregnant women with abnormal glucose metabolism.
