From the Guidelines
Ketones of 6.8 and BGL of 9.9 require immediate hospitalization for aggressive fluid resuscitation, insulin therapy, and electrolyte management to prevent morbidity and mortality. The patient's condition is indicative of diabetic ketoacidosis (DKA), a serious complication of diabetes that can lead to severe morbidity and mortality if not treated promptly and effectively 1.
Key Treatment Goals
- Restoration of circulatory volume and tissue perfusion
- Resolution of ketoacidosis
- Correction of electrolyte imbalance and acidosis
- Treatment of any underlying cause of DKA, such as sepsis, myocardial infarction, or stroke
Treatment Approach
Treatment begins with IV fluids, typically 0.9% saline at 15-20 mL/kg/hr for the first hour, then adjusted based on hydration status 1.
- Regular insulin should be administered as an IV bolus of 0.1 units/kg followed by continuous infusion at 0.1 units/kg/hr until blood glucose reaches 200-250 mg/dL, then reduced to 0.02-0.05 units/kg/hr while adding dextrose to IV fluids.
- Potassium replacement is crucial when levels fall below 5.3 mEq/L, typically given as 20-30 mEq/L in IV fluids.
- Bicarbonate therapy is generally reserved for severe acidosis (pH < 6.9) 1.
Monitoring and Follow-up
Frequent monitoring of glucose (hourly), electrolytes (every 2-4 hours), and acid-base status is essential 1.
- The underlying cause of DKA must be identified and addressed, commonly infection, medication non-compliance, or new-onset diabetes.
- After resolution, patients should transition to subcutaneous insulin before stopping IV insulin, receive diabetes education, and have close follow-up care. The use of bicarbonate in patients with DKA has been shown to make no difference in the resolution of acidosis or time to discharge, and its use is generally not recommended 1. In critically ill and mentally obtunded individuals with DKA or hyperosmolar hyperglycemia, continuous intravenous insulin is the standard of care 1. Successful transition from intravenous to subcutaneous insulin requires administration of basal insulin 2–4 h before the intravenous insulin is stopped to prevent recurrence of ketoacidosis and rebound hyperglycemia 1.

From the Research
Diabetic Ketoacidosis (DKA) Management
Given the ketone level of 6.8 and blood glucose level (BGL) of 9.9, it is crucial to manage the condition effectively to prevent further complications. The management of DKA involves:
- Restoration of circulating volume and electrolyte replacement 2, 3
- Correction of insulin deficiency to resolve metabolic acidosis and ketosis 2, 4
- Reduction of the risk of cerebral edema 2
- Avoidance of other complications such as hypoglycemia, hypokalemia, hyperkalemia, and hyperchloremic acidosis 2, 3
Treatment Guidelines
The treatment guidelines for DKA include:
- Intravenous fluid replacement to restore circulating volume 3
- Intravenous insulin infusion to correct insulin deficiency 2, 3
- Electrolyte replacement, particularly potassium, to prevent hypokalemia 2, 3
- Monitoring of vital signs, neurological signs, and biochemical response to treatment 2
Specific Considerations
In cases where the patient is following a ketogenic diet, there is a potential risk of developing euglycemic DKA, characterized by metabolic acidosis, ketosis, and blood glucose levels < 250 mg/dL 5. It is essential to consider dietary risk factors in the management of DKA. Additionally, pregnancy can complicate the management of DKA, and insulin plays a crucial role in reversing hyperglycemia and acidosis 6.
Monitoring and Adjustment
Regular monitoring of serum glucose, ketone levels, and electrolytes is necessary to adjust the treatment plan accordingly 2, 3. The treatment plan may need to be modified based on the patient's response to therapy, and it is crucial to identify and treat any underlying precipitating events 2, 4.
