Real Time Continuous Glucose Monitoring System in T2DM With Pregnacy

Brief Summary

The prevalence of type 2 diabetes mellitus (T2DM) in women of childbearing age is increasing rapidly, and low glucose compliance leads to an increased risk of adverse pregnancy outcomes for mothers and infants during pregnancy in women with T2DM. Real-time continuous glucose monitoring (CGM) is an important tool for glucose monitoring and patient education, as it can continuously record blood glucose throughout the day and provide real-time feedback on high and low blood glucose levels. This is a multicenter, open-label, randomized controlled clinical study to investigate the efficacy, safety, and maternal and infant pregnancy outcomes of using real-time CGM monitoring compared with conventional self-monitoring of blood glucose (SMBG) on the basis of multidisciplinary management in pregnant women with T2DM. One hundred and twenty pregnant women with T2DM in early pregnancy who were enrolled in intensive insulin therapy were randomly divided into the real-time CGM group and the conventional SMBG group. The real-time CGM intervention group wore real-time CGM for more than 50% of the pregnancy in addition to regular SMBG; the control group only performed regular SMBG. Both groups wore Medtronic iPro 2 for 3 days in early, mid and late pregnancy, and the time in the target range of blood glucose (TIR) was recorded in a blinded manner. Primary outcome: differences in TIR between the two groups of pregnant women in early, mid, and late pregnancy. Secondary outcomes included differences in glycated hemoglobin, hypoglycemia, insulin dose before delivery, pregnancy weight gain, and maternal and infant pregnancy outcomes.
