[Euglycemic ketoacidosis in gestational diabetes].

In this case report, a pregnant woman with diet-controlled gestational diabetes and hyperemesis developed severe euglycemic ketoacidosis (DKA) following administration of betamethasone for threatened preterm labor. Arterial blood gas demonstrated metabolic acidosis accompanied by elevated ketones and normoglycemia. Intensive care management using a modified pregnancy-adapted protocol resulted in complete maternal recovery and progression to term. Although uncommon, euglycemic DKA in pregnancy is a potentially life-threatening condition that necessitates prompt recognition and coordinated care.
