Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Provides free water and sodium chloride to expand extracellular fluid volume and correct electrolyte imbalances. Dextrose is metabolized to carbon dioxide and water, providing calories and preventing ketosis. Sodium chloride dissociates into sodium and chloride ions, maintaining osmotic pressure and acid-base balance.
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 and electrolyte requirements. Typical adult: 500-1000 mL at 50-100 mL/hour, adjusted based on clinical 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: not applicable (endogenous substrate); glucose half-life ~1.5–2 hours in circulation under normal conditions, prolonged in hyperglycemia. Sodium chloride: not applicable as ions are electrolytes with no elimination half-life; renal clearance depends on glomerular filtration and tubular reabsorption.
Normal renal function: 4–6 hours (terminal). In oliguria or anuria, half-life may extend to >24 hours, requiring dose adjustment.
Dextrose is fully metabolized to carbon dioxide and water; no significant renal excretion of intact dextrose. Sodium chloride is excreted renally; sodium and chloride ions are eliminated via kidneys, with excretion proportional to intake and renal function. No biliary or fecal elimination of intact components.
Primarily renal (glomerular filtration); >90% excreted unchanged in urine. Biliary/fecal elimination is negligible (<1%).
