Management of Sepsis in Diabetic Ketoacidosis
Immediate Assessment and Stabilization
- The American Diabetes Association recommends treating both sepsis and diabetic ketoacidosis simultaneously with aggressive fluid resuscitation, continuous IV insulin, electrolyte management, and immediate empiric antibiotics while obtaining cultures from all suspected infection sites 1, 2
Concurrent Treatment of Sepsis and DKA
- The American College of Cardiology recommends beginning with balanced electrolyte solutions at 15-20 mL/kg/hour during the first hour to restore circulatory volume and tissue perfusion 2
- Norepinephrine should be used as the first-line vasopressor over dopamine if shock persists despite adequate fluid resuscitation, as dopamine is associated with increased complications in septic shock 5
Electrolyte Management
- The Infectious Diseases Society of America recommends considering bicarbonate only if pH <6.9, as studies show no difference in resolution of acidosis or time to discharge, and it may worsen ketosis, cause hypokalemia, and increase cerebral edema risk 1, 2, 3
Monitoring During Treatment
- The American Association of Clinical Endocrinologists recommends drawing blood every 2-4 hours to determine serum electrolytes, glucose, blood urea nitrogen, creatinine, osmolality, and venous pH 2, 3
Special Considerations for Sepsis-Complicated DKA
- The American Journal of Kidney Diseases recommends targeting blood glucose of 110-149 mg/dL in critically ill patients to decrease risk of acute kidney injury and other morbidity 5
- The American Journal of Kidney Diseases also recommends providing nutritional support by the enteral route when possible, and not withholding protein supplementation, as patients with DKA complicated by sepsis are often highly catabolic 5
