Diabetic Coma: Drug Therapy

Therapy goals

  • Slow normalization of blood glucose (BG).
  • Balancing the water and acid-base balance
  • Balancing the electrolytes (blood salts)

Therapy recommendations

  • Diabetic ketoacidosis (DKA; synonym: ketoacidotic coma) is primarily corrected by insulin, fluid, and potassium administration
  • Hyperosmolar nonketotic coma or syndrome (HNKS; synonyms: hyperosmolar diabetic coma; hyperglycemic coma) is treated by administration of saline and insulin and potassium.
  • See also under “Other therapy.”

Active substances (main indication)

Active ingredient group Active ingredients Special features
Full electrolyte solution NaCl solution 0.9 DKA: typically a minimum of 3 L of saline in the first 5 hours.

See above under “Additional notes.”

Ringer’s solution (isotonic electrolyte solution for intravenous infusion)
Insulin Normal insulin No insulin therapy without volume administration In HNKS: insulin is administered only after the first liter of saline has been given
Hypotonic solution Glucose 5 % Do not pause insulin because of lipolysis
Electrolytes Potassium From insulin therapy, when BG decreases
Phosphate Consider with serum phosphate <0.5 mmol/l KI (not) in renal insufficiency/renal impairment
