Hyperosmolar Hyperglycemic State Treatment Guidelines

Initial Assessment and Diagnosis

• Clinical presentation of Hyperosmolar Hyperglycemic State ranges from mild hyperglycemia to severe hyperglycemia with dehydration, altered mental status, and coma, according to the American Diabetes Association 1

Treatment Algorithm

1. Fluid Resuscitation

• The American Diabetes Association recommends beginning fluid resuscitation with 0.9% sodium chloride solution at 15-20 mL/kg/hour during the first hour to restore circulatory volume and tissue perfusion 3
• Continue fluid replacement to correct estimated deficits within the first 24 hours, as suggested by the American Diabetes Association 3

2. Insulin Therapy

• When insulin is required, the American Diabetes Association recommends administering an intravenous bolus of regular insulin at 0.1 units/kg body weight, followed by a continuous infusion at 0.1 units/kg/hour 1, 3

3. Electrolyte Management

• Monitor potassium levels closely as total body potassium deficits are common despite potentially normal or elevated initial serum levels due to dehydration, according to the American Diabetes Association 3
• Begin potassium replacement after serum levels fall below 5.5 mEq/L, assuming adequate urine output, as recommended by the American Diabetes Association 3

4. Transition from IV to Subcutaneous Insulin

• Successful transition from intravenous to subcutaneous insulin requires administration of basal insulin 2-4 hours before the intravenous insulin is stopped to prevent rebound hyperglycemia, according to the American Diabetes Association 1, 2

Monitoring During Treatment

• Monitor blood glucose at least every 2-4 hours, as recommended by the American Diabetes Association 1, 4
• Draw blood every 2-4 hours to determine serum electrolytes, glucose, blood urea nitrogen, creatinine, osmolality, and venous pH, according to the American Diabetes Association 3

Identifying and Treating Precipitating Causes

• Identify and treat any correctable underlying cause such as sepsis, myocardial infarction, or stroke, as recommended by the American Diabetes Association 1, 2
• Infection is the most common precipitating factor in the development of Hyperosmolar Hyperglycemic State, according to the American Diabetes Association 6

Discharge Planning

• A structured discharge plan tailored to the individual patient should be developed to reduce length of hospital stay and readmission rates, as recommended by the American Diabetes Association 7, 4
