[Continuous Blood Glucose Monitoring of Hyperglycemia in Acute Stroke Patients Receiving Enteral Tube Feeding].

Severe hyperglycemia often occurs when acute stroke patients receive enteral tube feeding. Hyperglycemia should be managed because it adversely affects stroke outcome. However, it remains unclear how blood glucose level (BGL) changes with enteral nutrition in acute stroke patients. Our purpose was to investigate features of the blood glucose curve in acute stroke patients receiving enteral feeding. We retrospectively evaluated acute stroke patients who developed hyperglycemia during enteral tube feeding and underwent CGM in our institution. We evaluated characteristics of blood glucose curves, fasting and peak BGL, and time to peak of BGL. Six patients were analyzed. The median fasting BGL was 125.5 mg/dL and the median peak BGL was 351.5 mg/dL. The blood glucose curve showed the following characteristics following: 1) BGL elevated slowly reach the peak in 180 to 240 minutes; 2) BGL decreased slowly or very little after its peak; 3) there was a large gap between fasting and peak BGL regardless of presence of diabetes mellitus. We grouped the curves into four types by time to peak and how BGL decreased after peak. (Received August 17, 2017; Accepted February 1, 2018; Published July 1, 2018).
