目的了解动态血糖监测在老年2型糖尿病中的临床意义。方法将25例老年2型糖尿病患者按Hb A1c水平分为Hb A1c≤6.5%组和Hb A1c>6.5%组,使用CGMS连续监测患者血糖48h后,分析两组患者分时分段血糖值分布情况。结果血糖控制良好(Hb A1c≤6.5%)老年2型糖尿病患者更容易发生低血糖,多发生在22:00~4:00,且均为无症状性低血糖。血糖控制不良(Hb A1c>6.5%)老年2型糖尿病患者更容易出现餐后高血糖,且三餐后均易发生。结论 CGMS通过动态监测老年2型糖尿病患者血糖波动情况,能够及时发现治疗过程中出现的高血糖、低血糖现象,可提高治疗的安全性,对指导治疗有一定的临床意义。
Objective To understand the clinical significance of ambulatory blood glucose monitoring in type 2 diabetes mellitus in the elderly. Methods Twenty-five elderly patients with type 2 diabetes were divided into Hb A1c≤6.5% group and Hb A1c> 6.5% according to the level of Hb A1c. After continuous monitoring of blood glucose by CGMS for 48 hours, the distribution of time- . Results Good glycemic control (Hb A1c ≤ 6.5%) is more likely to occur in elderly patients with type 2 diabetes hypoglycemia, often occurs in the 22: 00 ~ 4: 00, and are asymptomatic hypoglycemia. Poor glycemic control (Hb A1c> 6.5%) Elderly patients with type 2 diabetes are more likely to have postprandial hyperglycemia and are more likely to develop after three meals. Conclusion CGMS can detect the hyperglycemia and hypoglycemia in the course of treatment by dynamically monitoring the fluctuation of blood glucose in elderly patients with type 2 diabetes mellitus, which can improve the safety of treatment and has some clinical significance in guiding treatment.
