应用动态血糖监测评估2型糖尿病患者的夜间低血糖

Evaluation of nocturnal hypoglycemia in patients with type 2 diabetes via continuous glucose monitoring system

动态血糖监测系统（CGMS）监测1147例2型糖尿病患者血糖变化。结果显示，夜间低血糖多发生在22：00—2：00，与平均血糖及晚餐后3h血糖负相关，晚餐后3h血糖4．7mmol／L时发生夜间低血糖几率达50％。

The variation of blood glucose in 1 147 patients with type 2 diabetes mellitus was monitored by continuous glucose monitoring system（CGMS）. The results showed that the peak hours of nocturnal hypoglycemia occurred during 22 ： 00-2 ： 00. The incidence of nocturnal hypoglycemia was negatively correlated with mean blood glucose and blood glucose at three hours after supper. The probability of hypoglycemia was up to 50% when blood glucose level had been as low as 4.7 mmol/L at 3 h after supper.
