Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Dextrose provides caloric support and prevents ketosis; sodium chloride maintains electrolyte balance; potassium chloride replaces potassium losses and restores intracellular potassium levels.
Magnesium sulfate causes decreased release of acetylcholine at the neuromuscular junction, reducing muscle contractility. It also blocks calcium channels, leading to vasodilation and anticonvulsant effects.
Intravenous infusion. Dose determined by fluid, electrolyte, and caloric requirements. Typical adult maintenance: 100-200 mL/hour (2-4 L/day) of D5 0.45% NaCl with 20 mEq/L KCl. Rate adjusted based on serum potassium and fluid status.
IV: 1-4 g as a 10-20% solution, rate not exceeding 1 g/min; for eclampsia: 4-5 g IV bolus then 1-2 g/hour IV infusion.

Dextrose: plasma half-life approximately 20-30 minutes; prolonged in renal impairment or diabetes. Potassium: terminal half-life ~8 hours (intracellular equilibration); clinical context: hypokalemia correction requires monitoring.
Normal renal function: 4–6 hours (terminal). In oliguria or anuria, half-life may extend to >24 hours, requiring dose adjustment.
Dextrose: primarily metabolized to CO2 and water; <5% excreted unchanged in urine. Sodium, chloride, and potassium: primarily excreted renally (90%+); small fecal/biliary loss.
Primarily renal (glomerular filtration); >90% excreted unchanged in urine. Biliary/fecal elimination is negligible (<1%).
