Application of continuous glucose monitoring system in the gestational patients with impaired glucose regulation / 中华临床营养杂志

ABSTRACT

Objective To evaluate the value of continuous glucose monitoring system (CGMS) in the gestational patients with impaired glucose regulation. Methods The glucose level in the subcutaneous tissue was monitored by CGMS for 3 days in 6 patients with gestational diabetes mellitus (GDM) and 6 patients with gestational impaired glucose tolerance (GIGT). The fluctuation coefficient of blood glucose, percentage of hyperglycemic time, and percentage of hypoglycemic time were calculated. Results As shown by CGMS, the fluctuation coefficient of blood glucose, mean glucose level, percentage of hyperglycemic time, percentage of hypoglycemic time, mean fasting blood glucose, and mean postprandial blood glucose (PBG) levels were not significantly different between GDM group and GIGT group (P ＞ 0. 05). The time for reaching the peak PBG level ranged 90-120minutes in both two groups (P ＞ 0. 05). No sensor-related adverse events were noted. Conclusions It is safe to apply CGMS sensor in pregnant women. The blood glucose profiles are comparable between GDM and GIGT patients by CGMS; therefore, control of blood glucose should be equally strict in patients with GIGT as those with GDM.
