From the Research

In pregnancy, a serum ketone level of ≥3 mmol/L is diagnostic of diabetic ketoacidosis (DKA). This threshold is the same as in non-pregnant individuals, but it's essential to note that DKA can develop at lower blood glucose levels during pregnancy (often around 200 mg/dL compared to 250-300 mg/dL in non-pregnant patients) 1. The diagnosis of DKA in pregnancy is critical due to the increased risk of maternal and fetal morbidity and mortality.

Key Considerations

  • DKA can occur in pregnant women with type 1 or type 2 diabetes, as well as those with gestational diabetes 1.
  • The condition is characterized by hyperglycemia, metabolic acidosis, and elevated serum ketones, although euglycemic DKA can also occur 2.
  • Treatment should be initiated promptly with intravenous fluids, insulin therapy, and electrolyte replacement, particularly potassium 3, 4.
  • Close monitoring of maternal glucose levels, electrolytes, and fetal status is crucial, with a target glucose range of 100-150 mg/dL during treatment 3.

Management Strategies

  • Fluid replacement and insulin therapy are essential components of DKA management in pregnancy 3, 4.
  • Electrolyte replacement, particularly potassium, is critical to prevent complications 3, 4.
  • Fetal monitoring is essential to assess the well-being of the fetus and guide management decisions 1.
  • The treatment approach should be tailored to the individual patient's needs, taking into account factors such as renal disease, congestive heart failure, and older age 4.

Outcome Prioritization

The primary goal of DKA management in pregnancy is to minimize morbidity and mortality for both the mother and the fetus. Early recognition and aggressive management are crucial to achieve optimal outcomes. By prioritizing the diagnosis and treatment of DKA, healthcare providers can reduce the risk of complications and improve maternal and fetal outcomes 1, 4.
