Therapeutic advances in drug safety

Hyperkalemia is an electrolyte abnormality that may cause ventricular dysrhythmias and cardiac arrest. The presence of hyperkalemia may necessitate prompt treatment via intravenous insulin and dextrose. One notable complication of this therapy is the development of hypoglycemia. Previous trials have examined the impact of altering the insulin dose administered on hypoglycemia development; no trials to date however, have examined the impact of altering the dextrose dose. ⋯ In the overall patient population, use of 50 g of dextrose instead of 25 g does not reduce hypoglycemia incidence. However, it may be beneficial is select patient populations, such as patients without type 2 diabetes or patients with a baseline blood glucose <110 mg/dl. Administration of 50 g of dextrose did not appear to place patients at significant risk for hyperglycemia however and could be considered during treatment of hyperkalemia.
