Management of Diabetic Ketoacidosis

Initial Treatment Approach

  • Aggressive fluid resuscitation with isotonic saline at 15-20 mL/kg/hour is recommended to restore circulatory volume and tissue perfusion in patients with diabetic ketoacidosis (DKA) 1
  • Continuous intravenous insulin infusion at 0.1 units/kg/hour should be maintained until resolution of ketoacidosis, regardless of glucose levels, in DKA patients 1, 2
  • Electrolytes, particularly potassium, should be monitored and replaced as needed in patients with DKA 1, 2

Transition to Oral Intake and Monitoring

  • Once DKA is resolving and the patient is able to eat, they should transition to a multiple-dose insulin schedule using a combination of short/rapid-acting and intermediate/long-acting insulin, as recommended by the American Diabetes Association 3, 2
  • Blood should be drawn every 2-4 hours to determine serum electrolytes, glucose, and other parameters to monitor resolution of acidosis in DKA patients 2
  • DKA resolution requires glucose <200 mg/dL, serum bicarbonate ≥18 mEq/L, venous pH >7.3, and anion gap ≤12 mEq/L, according to the American Diabetes Association guidelines 2

Special Considerations and Evidence-Based Approach

  • The American Diabetes Association guidelines do not recommend keeping DKA patients NPO as a standard practice, and instead suggest allowing patients to eat when they are able to, while providing appropriate insulin coverage 3
  • For patients who cannot eat, intravenous insulin and appropriate fluid management should continue until oral intake is possible, with glucose targets between 150-200 mg/dL until DKA resolution parameters are met 2

Enoxaparin in Diabetic Ketoacidosis Management

DKA Management Overview

  • Resolution of hyperglycemia is a key component of DKA management, as recommended by the American Diabetes Association 4
  • Treatment of underlying causes, such as sepsis, myocardial infarction, and stroke, is crucial in DKA management, according to the American Diabetes Association 5
  • Prevention of complications, including thromboembolism, is an essential aspect of DKA management, as suggested by the American Diabetes Association 4, 5

Thromboprophylaxis in DKA

  • A hypercoagulable state associated with DKA increases the risk of thrombosis, as reported by the American Diabetes Association 4
  • Enoxaparin can be administered to DKA patients as part of standard hospital thromboprophylaxis protocols, as recommended by the American Diabetes Association 5

Special Considerations

  • Renal function should be monitored regularly, as insulin therapy and fluid resuscitation can improve kidney perfusion and change enoxaparin clearance, according to the American Diabetes Association 5
  • Enoxaparin can be started upon admission after initial fluid resuscitation has begun, as suggested by the American Diabetes Association 5
  • Enoxaparin administration should not interfere with the standard DKA management protocol, which includes intravenous fluids, insulin therapy, and electrolyte replacement, as recommended by the American Diabetes Association 4, 5
