Intraoperative management record indicating the progress of glycemic control. During dental implant surgery, the patient abruptly complained of discomfort such as malaise that seemed to be a symptom of hypoglycemia. Blood glucose was promptly measured at 32 mg/dL and recognized as severe hypoglycemia. Oral glucose and an electrolyte-combined infusion of glucose were administered, and he immediately recovered, with blood glucose increasing to 65 mg/dL 15 min after glucose administration and to 127 mg/dL by the end of the surgical procedure
