The FreeStyle Libre Flash Glucose Monitoring System allows users to obtain sensor glucose values by scanning with the reader or their mobile phone. We report a case of a 59-year-old man with type 1 diabetes mellitus who developed diabetic ketoacidosis due to a sensor defect. After replacing the sensor with a new one, the glucose value shown in the device was much lower than usual, which made him consider that he was hypoglycemic. Accordingly, he reduced his insulin dose and eventually developed diabetic ketoacidosis. He was unaware of the discrepancy due to the lack of self-monitoring of his blood glucose, although he was educated to do. In sum, glucose monitoring with the FreeStyle Libre is helpful; however, it is necessary to remind the patient that a sensor defect leading to a severe complication frequently happens.
FreeStyle Libre 瞬感葡萄糖监测系统允许用户通过扫描读取器或移动电话来获得传感器葡萄糖值。我们报告了一例 59 岁的 1 型糖尿病患者，由于传感器故障导致糖尿病酮症酸中毒。更换新传感器后，设备显示的血糖值远低于正常水平，这使他认为自己出现了低血糖。因此，他减少了胰岛素剂量，最终导致糖尿病酮症酸中毒。尽管他接受过相关教育，但由于缺乏自我血糖监测，他没有意识到这种差异。总之，使用 FreeStyle Libre 进行血糖监测是有帮助的；然而，有必要提醒患者，传感器故障会经常导致严重并发症。
