动态血糖监测系统在妊娠期糖代谢异常患者中的应用

Application of continuous glucose monitoring system in the gestational patients with impaired glucose regulation

目的评估动态血糖监测系统（CGMS）在妊娠期糖代谢异常患者中的应用价值。方法采用CGMS对6例妊娠糖尿病（GDM）患者和6例妊娠期糖耐量受损（GIGT）患者进行连续3d的皮下组织葡萄糖监测，计算血糖波动系数、高血糖时间比和低血糖时间比。结果两组患者的血糖波动系数、葡萄糖平均值、高血糖时间比、低血糖时间比、空腹血糖平均值、餐后血糖平均值差异均无统计学意义（P均〉0．05）。两组患者早、中、晚餐3餐达到餐后血糖峰值的时间及峰值浓度差异无统计学意义（P均〉0．05），达峰时间均为餐后90～120min。未发生与探头置入相关的不良反应。结论在妊娠妇女中使用CGMS感应器是安全的，GDM和GIGT患者经CGMS监测血糖水平没有显著差异，GIGT的治疗应该和GDM同样严格。

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 gesrational 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 90-120 minutes 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.
