Changes of interstitial glucose level measured by the subcutaneous continuous glucose monitoring system (IG) (black line), blood glucose level (BG) (white circle), and hemodynamics during general anesthesia for resection of insulinoma. The light grey zone indicates the normal value of casual BG (70-200 mg/dL). The dotted line indicates heart rate (HR) and the grey bar indicates blood pressure (BP). C indicates calibration of the subcutaneous continuous glucose monitoring system; T: tracheal intubation; Ep: epidural catheterization; E: extubation;  : start or end of the operation; x: start or end of anesthesia.

Analyzer (Radiometer, Brea, CA, USA) was 71 mg/dL, which was compatible with IG of 73 mg/dL. An additional 2 g of glucose was given intravenously before the start of surgery, and IG increased from 77 mg/dL to 101 mg/dL at 20 minutes (Figure 1). After that, IG mildly decreased and returned to almost the same level after 1 hour.
