Dextrose Administration Guidelines
Initial Treatment
- For continuous infusion in hypoglycemia or insulin overdose, administer D10W at 100 mL/kg per 24 hours, titrating to maintain blood glucose between 100-180 mg/dL, as recommended by the American Academy of Pediatrics 1, 2
- Administer 5-10 gram aliquots of D10W intravenously every 1-2 minutes until symptoms resolve, targeting a post-treatment glucose of 100-180 mg/dL, with a strength of evidence based on clinical guidelines 1
- Use a patient-specific formula to guide dosing: (100 − current blood glucose in mg/dL) × 0.2 grams = total dose of dextrose needed, according to the American Academy of Pediatrics 1
- For acute hypoglycemia, 0.5-1.0 g/kg of dextrose as D10W requires 5-10 mL/kg, as stated by the American Academy of Pediatrics 3, 4
Continuous Infusion
- Start D10W at 100 mL/kg per 24 hours with appropriate maintenance electrolytes, as recommended by the American Academy of Pediatrics 1, 2, 3, 4
- This translates to approximately 7 mg/kg/minute of dextrose, with a maximum infusion rate not exceeding 5-7 mg/kg/minute to avoid hyperglycemia, according to the American Gastroenterological Association 3, 4, 5
- Older children and adults may require substantially lower doses than the pediatric standard, as stated by the American Academy of Pediatrics 3, 4
Monitoring and Discontinuation
- Recheck blood glucose 15 minutes after initial treatment, and monitor every 30-60 minutes initially when starting continuous infusion, as recommended by the American Academy of Pediatrics 1, 2
- Continue monitoring every 1-2 hours during ongoing dextrose infusion, and check serum potassium and sodium levels carefully, as dextrose administration causes electrolyte shifts, according to the American Academy of Pediatrics 1, 2, 3, 4
- Never abruptly discontinue dextrose infusion in insulin overdose patients, and reduce infusion rate by 50% over the final 30 minutes before discontinuing to prevent rebound hypoglycemia, as recommended by the American Academy of Pediatrics 1, 2
Important Considerations
- Avoid reflexive full-dose administration, as rapid and repeated large doses can cause excessive blood glucose elevation and have been associated with cardiac arrest and hyperkalemia, according to the American Academy of Pediatrics 1
- Titrate based on initial glucose level and patient response rather than administering fixed large doses, as recommended by the American Academy of Pediatrics 1
- D50W is irritating to veins; dilution to D10W or D25W is desirable, as stated by the American Academy of Pediatrics 3, 4
