Life threatening hypoglycemia can occur during critical illness in infants with underlying hyperinsulinemia or metabolic conditions, such as glycogen storage diseases. Using a continuous glucose monitor (CGM) can provide insight into glycemic trends with this high-risk patient population in the intensive care setting. Barriers to usage of CGMs in the intensive care unit include familiarity with CGMs devices among staff, safety, and cost.
We describe the first reported case of safely utilizing the newest Dexcom G7 continuous glucose monitor in an infant with hyperinsulinemia undergoing high frequency oscillatory ventilator (HFOV) support for acute respiratory distress syndrome (ARDS) to detect early hypoglycemic episodes during critical illness while on continuous glucose infusion.
There is limited information on using the Dexcom G7 CGM device in infants with underlying hypoglycemic conditions on HFOV support. The use of HFOV poses a unique physiological challenge for using a CGM device. We demonstrate that the Dexcom G7 is safe to use while on HFOV. The device provided important glycemic trends, which helped to reduce the number of point-of-care tests and allowed for early detection of hypoglycemia.
患有潜在高胰岛素血症或代谢性疾病（如糖原贮积病）的婴儿在危重病期间可能发生危及生命的低血糖。在重症监护环境中，使用连续血糖监测仪（CGM）可以深入了解这类高危患者群体的血糖趋势。重症监护病房中使用CGM的障碍包括工作人员对CGM设备的熟悉程度、安全性和成本。
我们描述了首例报告的病例，一名患有高胰岛素血症的婴儿在接受高频振荡通气（HFOV）支持治疗急性呼吸窘迫综合征（ARDS）时，安全使用最新的德康G7连续血糖监测仪，以便在持续葡萄糖输注期间的危重病期间检测早期低血糖发作。
关于在接受HFOV支持的患有潜在低血糖症的婴儿中使用德康G7 CGM设备的信息有限。使用HFOV对使用CGM设备提出了独特的生理挑战。我们证明德康G7在HFOV期间使用是安全的。该设备提供了重要的血糖趋势，有助于减少即时检测次数，并能早期发现低血糖。
