Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Dextrose is a monosaccharide that provides caloric support and prevents ketosis by entering the glycolytic pathway. Sodium chloride 0.9% is an isotonic crystalloid that expands extracellular fluid volume by increasing intravascular osmotic pressure. The combination repletes both free water and sodium deficits.
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, administered at a rate determined by clinical condition; typical maintenance fluid rate for adults is 100-200 mL/hour (2.4-4.8 L/day) with dextrose 2.5% providing 25-50 g glucose daily.
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: 30-60 minutes (utilization half-life) for glucose; for IV fluids, distribution half-life is minutes. Sodium chloride: elimination half-life varies with volume status; typical serum sodium half-life ~1-2 hours for acute load.
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: excreted renally with >90% of sodium and chloride ions eliminated via kidneys; negligible biliary/fecal elimination.
Primarily renal (glomerular filtration); >90% excreted unchanged in urine. Biliary/fecal elimination is negligible (<1%).
