Managing diabetic ketoacidosis (DKA) in an intensive care

When treating patients with DKA, the following points
must be considered and closely monitored:
• Correction of fluid loss with intravenous fluids.
• Correction of hyperglycemia with insulin.
• Correction of electrolyte disturbances, particularly
potassium loss.
• Correction of acid-base balance.
• Treatment of concurrent infection, if present.
