What dosage of D 25 should be given to a patient older than two years with hypoglycemia?

The appropriate dosage of D 25 for a patient older than two years with hypoglycemia is typically in the range of 2 to 4 mL per kilogram. This dosage is based on clinical guidelines which recommend that D 25, a hypertonic solution, should be administered attentively, considering both the severity of the hypoglycemia and the patient's overall clinical status.

Administering 2 to 4 mL per kilogram ensures that patients receive sufficient treatment to elevate their blood glucose levels without exceeding safe limits that could lead to complications from rapid changes in serum glucose levels. This range balances the need for effective correction of hypoglycemia with the necessity for safety, especially in pediatric patients who may be more sensitive to rapid shifts in blood sugar.

In contrast, the other dosage ranges are more likely to result in either under-treatment or excessive treatment, both of which can pose risks. For instance, a lower dose may not sufficiently counteract severe hypoglycemia, whereas a higher dose could lead to complications such as hyperglycemia or osmotic demyelination syndrome. Therefore, the selected dosage is congruent with established protocols for managing pediatric hypoglycemia effectively.
