A case of euglyacemic diabetic ketoacidosis in a patient with gestational diabetes mellitus.

A 30-year old woman at 30 weeks gestation with insulin-controlled gestational diabetes was admitted with nausea and vomiting. Plasma glucose was 3.3 mmol/l with pH 7.23 and raised capillary ketones at 6.1 mmol/l. She was diagnosed with euglycaemic diabetic ketoacidosis. Cardiotocography showed good fetal movement and accelerations. She was given intramuscular betamethasone and started on intravenous dextrose, insulin and 0.9% saline with potassium chloride with resolution of ketosis. Euglycaemic diabetic ketoacidosis has been reported during pregnancy in patients with type 1 and type 2 diabetes. We believe that this is a report of such an occurrence in a patient with gestational diabetes.
