    2. Diabetes Mellitus Glucose Management
    3. Diabetes Sick Day Management
  2. Preparations
    1. Oral: Equivalents of 15 grams Glucose (1 carbohydrate)
      1. Three Glucose tablets (or 15 grams of Glucose gel)
      2. Fruit juice 1/2 cup (4 ounces)
      3. Regular soda 3/4 cup (6 ounces)
      4. Milk 1 cup (8 ounces)
      5. Honey or corn syrup 3 teaspoons
      6. Crackers (6 saltine crackers)
    2. Glucagon Intramuscular or Subcutaneous
      1. Precautions
        1. Transient effects only
        2. Ineffective when Liver Glycogen depleted
        3. Vomiting and aspiration risk
          1. Roll patient onto their side when used
      2. Dose
        1. Teens and adult: 1 mg
        2. Children: 0.5 mg (0.5 ml) or 15 mcg/kg
    3. Administer Intravenous Dextrose
      1. Bolus: 10-25 ml of D50W IV
        1. Alternative: 100 ml of D10W IV (less likely to cause rebound Hypoglycemia than D50W)
      2. Maintenance: D10W IV at 100 cc/hour until stable
      3. Keep plasma Glucose over 100 mg/dl
      4. May require 10 grams/hour IV
  3. Protocol: Immediate Glucose Replacement
    1. Mild Hypoglycemia (BG 60-70 mg/dl): Give 15 carb grams
      1. Glucose oral gel 40% 15 grams orally or
      2. Glucose 3 tablets orally or
      3. Juice 4 ounces orally
    2. Moderate Hypoglycemia (BG 45-59): Give 20 carb grams
      1. Glucose oral gel 40% 20 grams orally or
      2. Glucose 4 tablets orally or
      3. Juice 6 ounces orally or
      4. Dextrose D10W 100 ml IV or D50 25 ml IV
    3. Severe Hypoglycemia (BG <45): Give 30 carb grams
      1. Glucose oral gel 40% 30 grams orally or
      2. Glucose 6 tablets orally or
      3. Juice 8 ounces orally or
      4. Dextrose D10W 100 ml IV or D50 25 ml IV
    4. Unconscious with severe Hypoglycemia (BG<45)
      1. Dextrose 50% 25 ml IV or
      2. Glucagon 1 mg SQ or IM (0.5 mg for child)
        1. Vomiting and aspiration risk
        2. Roll patient onto their side when used
  4. Protocol: Approach
    1. Recognize signs of Hypoglycemia (e.g. Altered Level of Consciousness or confusion, sweating, Dizziness)
      1. Test Blood Glucose for Hypoglycemia symptoms (but do not delay replacement)
    2. Treat Hypoglycemia if Blood Glucose <70 mg/dl (or <80-90mg/dl in elderly)
      1. Deliver Glucagon to temporize briefly until Glucose can be absorbed
      2. Deliver Emergency Glucose Replacement (15-20 grams carbohydrate)
    3. Glucose monitoring
      1. Monitor Blood Glucose every 15 minutes until >100 mg/dl
      2. Redose Glucose replacement per above every 15 min as needed
    4. Eat a small meal (e.g. turkey sandwich) that contains protein and fat once Blood Glucose has returned to a normal level
  5. Precautions
    1. Acute Hypoglycemia associated with long acting Oral Hypoglycemic agents (e.g Sulfonylureas)
      1. Observe in hospital setting until hypoglycemic agent has been sufficiently cleared to prevent further Hypoglycemia
    2. Consider differential diagnosis
      1. See Hypoglycemia causes
      2. Septic Shock (esp. in the elderly)
  6. Management: Disposition
    1. Glucose correction
      1. D50W administration
        1. D50W results in rebound Hypoglycemia (consider 100 ml D10W instead)
        2. After correction, observe for several hours with Glucose checked every 1-2 hours
      2. Meal after correction
        1. Patient must have some longer acting foods containing protein and fat to prevent recurrent Hypoglycemia
    2. Oral Hypoglycemic agents
      1. Metformin (Glucophage)
        1. Unlikely to cause Hypoglycemia
      2. Sulfonylureas
        1. Prolonged Insulin release stimulation - observe for 24 hours
        2. Consider Octreotide 50-100 mcg IV
    3. Short-Acting Insulin (e.g. Humalog/Lispro, Novolog/Aspart)
      1. Short duration of observation after correction (peaks in 1 hour)
    4. Long-acting Insulin (basal Insulin)
      1. Lantus (Insulin Glargine)
        1. Constant basal rate without peak is unlikely to cause Hypoglycemia
        2. Typically does not affect disposition timing
      2. Levemir (Detemir)
        1. Onset at 1-2 hours and peak activity at 6-8 hours
        2. Observe for 6-8 hours with recheck Glucose every 1-2 hours
      3. Insulin Pump
        1. Detach and check pump for malfunction
    5. Indications for hospital observation stay
      1. Hypoglycemia on Sulfonylurea
      2. Elderly patients (esp. with Dementia, Renal Insufficiency)
