From the Guidelines
Diabetic ketoacidosis (DKA) treatment requires immediate hospitalization, typically in an intensive care unit, with a comprehensive approach focusing on fluid resuscitation, insulin therapy, and electrolyte management, as recommended by the most recent guidelines 1.
Key Components of DKA Treatment
- Initial treatment begins with aggressive intravenous fluid replacement using normal saline, with the rate adjusted based on hemodynamic status.
- Insulin therapy should be initiated with an IV insulin infusion, titrated to reduce blood glucose by 50-75 mg/dL per hour, without the need for an initial bolus in most cases.
- Potassium replacement is crucial, typically starting when levels fall below 5.3 mEq/L, aiming to maintain levels between 4-5 mEq/L.
- Bicarbonate therapy is generally not recommended, except in cases of severe acidosis (pH < 6.9), as its use has not been shown to improve outcomes 1.
Monitoring and Transition to Subcutaneous Insulin
- Throughout treatment, monitor glucose hourly, electrolytes every 2-4 hours, and assess for cerebral edema, especially in children.
- Once the patient improves (glucose < 200 mg/dL, bicarbonate > 18 mEq/L, pH > 7.3), transition to subcutaneous insulin, typically starting with a basal-bolus regimen, with the first subcutaneous dose given 2-4 hours before discontinuing IV insulin to prevent rebound hyperglycemia, as recommended by recent guidelines 1.
Underlying Cause Identification and Treatment
- The underlying cause of DKA must be identified and addressed, commonly infection, medication non-compliance, or new-onset diabetes.
- Treatment should be individualized based on a careful clinical and laboratory assessment, with consideration of the patient's specific needs and circumstances 1.
From the FDA Drug Label
Hyperglycemia (too much glucose in the blood) may develop if your body has too little insulin Hyperglycemia can be brought about by any of the following: Omitting your insulin or taking less than your doctor has prescribed. Eating significantly more than your meal plan suggests. Developing a fever, infection, or other significant stressful situation. In patients with type 1 or insulin-dependent diabetes, prolonged hyperglycemia can result in DKA (a life-threatening emergency) The first symptoms of DKA usually come on gradually, over a period of hours or days, and include a drowsy feeling, flushed face, thirst, loss of appetite, and fruity odor on the breath. With DKA, blood and urine tests show large amounts of glucose and ketones. Heavy breathing and a rapid pulse are more severe symptoms If uncorrected, prolonged hyperglycemia or DKA can lead to nausea, vomiting, stomach pain, dehydration, loss of consciousness, or death. Therefore, it is important that you obtain medical assistance immediately.
The treatment for Diabetic Ketoacidosis (DKA) is not explicitly stated in the provided text, but it is mentioned that patients should obtain medical assistance immediately if they experience symptoms of DKA 2.
From the Research
Treatment Overview
The treatment for Diabetic Ketoacidosis (DKA) involves several key components, including:
- Fluid and electrolyte replacement 3, 4, 5, 6
- Insulin therapy 3, 4, 5, 7, 6
- Treatment of precipitating causes 3, 5, 6
- Close monitoring to adjust therapy and identify complications 3, 5, 6
Fluid and Electrolyte Replacement
- The initial hydrating fluid is often 5 percent glucose in 0.45 percent saline plus 40 mEq of potassium chloride or buffered potassium phosphate 4
- Potassium replacement is almost always necessary, often requiring massive amounts of this ion due to the total body depletion seen with the development of ketoacidosis 3
- Phosphate replacement may be needed if serum levels fall toward the lower limits of normal values, to avoid the potential adverse effects of phosphate depletion 3
- Bicarbonate administration is controversial and should be reserved for patients whose pH is less than 7.0 to 7.1 3
Insulin Therapy
- Low-dose intravenous infusion is now the accepted mode of insulin delivery for patients with DKA 3
- Insulin is given by intravenous drip at an initial rate of about 0.1 u per kg per hour 4
- Subcutaneous rapid-acting insulin aspart injections can be effective in treating uncomplicated mild and moderate DKA in children 7
Treatment of Precipitating Causes
- Identifying and treating the underlying cause of DKA is crucial 3, 5, 6
- This may involve treating infections, managing other medical conditions, or adjusting diabetes treatment regimens 5, 6
