Background:
Artificial pancreas is usually used to manage hyperglycemia. We controlled prolonged hypoglycemia induced by insulin overdose using artificial pancreas.
Case presentation:
A 56-year-old female patient with type 2 diabetes mellitus was admitted to the emergency department after overdosing on 1,800 units each of insulin aspart and insulin degludec. She had also ingested 2 weeks of anti-anxiety medication. When the patient arrived at the hospital, her blood glucose level was 30 mg/dL and she was in a coma. Artificial pancreas (STG-55; Nikkiso, Tokyo, Japan) was used to control blood glucose levels because we were unable to predict the duration or degree of hypoglycemia. Blood glucose levels were safely controlled without the development of hypo- or hyperglycemia. Finally, the patient was discharged without any complications on day 7.
Conclusion:
The STG-55 artificial pancreas was very useful and convenient for controlling blood glucose levels in our insulin overdose patient.
