MAGNESIUM SULFATE vs SODIUM CHLORIDE 0.9% IN PLASTIC THERMOJECT KIT FOR CARDIAC OUTPUT USE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Magnesium sulfate acts as a physiological calcium channel blocker. It inhibits calcium influx into presynaptic nerve terminals, reducing acetylcholine release at the neuromuscular junction and decreasing muscle contraction. It also antagonizes NMDA receptors and stabilizes neuronal membranes.
Sodium chloride 0.9% is an isotonic crystalloid solution that increases intravascular volume by replacing extracellular fluid and electrolytes. It does not have a specific molecular target; its primary pharmacological effect is osmotic expansion of the vascular compartment.
IV: Loading dose 4-6 g over 20-30 minutes, followed by maintenance infusion 1-2 g/hour for seizure prophylaxis in severe preeclampsia/eclampsia. IM: 4-8 g deep IM initially, then 4 g every 4 hours as needed.
Intravenous injection of 10 mL of 0.9% sodium chloride solution for cardiac output determination via thermodilution, repeated as needed every 3-5 minutes for up to 3 injections per measurement set.

Clinical Note
moderateTerminal elimination half-life approximately 4-6 hours in patients with normal renal function; prolonged to 12-24 hours or more in renal impairment, necessitating dose adjustment
Not applicable as a conventional drug; sodium and chloride are endogenous electrolytes. The infused ions are distributed and eliminated according to body homeostasis. The plasma half-life of an infused sodium load is approximately 30-60 minutes in euvolemic individuals, but is highly variable based on renal function and volume status.
Primarily renal (90-95% as unchanged drug); minor biliary/fecal (<5%)
Primarily renal (>95%). Sodium and chloride ions are freely filtered at the glomerulus and undergo variable tubular reabsorption depending on volume status; excess is excreted unchanged in urine. Fecal and biliary elimination are negligible.
