Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Dextrose provides caloric support and restores blood glucose levels, while electrolytes (such as sodium, potassium, magnesium, chloride, acetate, and phosphate) replace deficits and maintain acid-base balance. The specific electrolyte composition in No. 48 (e.g., sodium, potassium, magnesium, chloride, acetate, phosphate) aids in rehydration and correction of electrolyte disturbances.
Dextrose 5% provides a source of carbohydrates and calories to restore blood glucose levels and correct dehydration. Potassium chloride replenishes potassium ions, which are essential for maintaining cellular membrane potential, nerve impulse transmission, and muscle contraction. The combination corrects hypokalemia and prevents potassium depletion during intravenous fluid therapy.
Intravenous administration; dosing is based on fluid and electrolyte requirements, typically 1-2 L per 24 hours for adults, infused at a rate of 100-200 mL/hour, adjusted according to clinical status and serum electrolyte levels.
Intravenous infusion: 500-1000 mL at a rate of 100-200 mL/hour, not exceeding 25 mEq potassium per hour (or 0.5 mEq/kg/hour) and a maximum concentration of 40 mEq/L. Total daily dose depends on fluid and electrolyte needs.

Dextrose: terminal elimination half-life is approximately 2-3 hours in non-diabetic individuals, reflecting glucose utilization and storage; prolonged in renal impairment due to decreased clearance of metabolites. Electrolytes: half-life varies; sodium and chloride have elimination half-lives of 6-12 hours; potassium half-life is 12-24 hours; magnesium half-life is 24-48 hours; acetate half-life is minutes (rapid metabolism).
Dextrose: not applicable (endogenous); potassium: 12-24 hours (distribution half-life), terminal phase not defined due to homeostatic regulation.
Dextrose is completely metabolized to carbon dioxide and water in the presence of insulin; minimal renal excretion (<5%) as unchanged glucose in normoglycemic individuals. Electrolytes (sodium, chloride, potassium, magnesium, acetate, gluconate) are primarily excreted renally; renal elimination accounts for >90% of sodium and chloride, ~80% of potassium, and ~70% of magnesium. Acetate is rapidly metabolized to bicarbonate. Gluconate is partially excreted renally and partially metabolized.
Renal: Potassium excreted primarily via kidneys (90%) with some fecal loss; dextrose is metabolized to CO2 and water, excreted renally as water and bicarbonate (less than 5% unchanged).
