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 provides magnesium ions, which are essential for various physiological processes. It acts as a cofactor for enzymatic reactions, stabilizes excitable membranes, and antagonizes calcium entry at the neuromuscular junction, leading to reduced acetylcholine release and muscle relaxation. In the CNS, it may act as a noncompetitive antagonist of NMDA receptors, exerting 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.
1 to 4 g intravenously as a 5% to 20% solution, rate not exceeding 150 mg/min; dosing frequency depends on indication (e.g., preeclampsia/eclampsia: 4-5 g IV loading then 1-2 g/hr infusion; hypomagnesemia: 1-2 g IV over 1-2 hours, may repeat based on serum magnesium levels).

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.
Terminal half-life approximately 4-5 hours in normal renal function; prolonged in renal impairment (up to 40 hours).
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 (90-100% as unchanged magnesium). Less than 1% biliary/fecal.
