Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Electrolyte and fluid replacement; dextrose provides caloric support.
Plasma-Lyte 148 is an isotonic crystalloid solution that provides electrolyte replacement and volume expansion. It mimics plasma electrolyte composition, with acetate and gluconate as bicarbonate precursors that are metabolized to bicarbonate in the liver and kidneys, helping to maintain acid-base balance.
Intravenous infusion; rate based on fluid and electrolyte requirements, typically 1-2 mL/kg/hour for maintenance in adults.
Intravenous infusion; dose determined by electrolyte and fluid requirements. Typical adult rate: 25-100 mL/hour.

Not applicable; components are endogenous substances. Dextrose has a plasma half-life of approximately 1.5-2.5 hours in normal glucose metabolism; electrolytes have half-lives dependent on renal function (e.g., sodium half-life ~1-2 days).
Not applicable; Plasma-Lyte 148 contains electrolytes and water that distribute according to body fluid compartments; infusion rate and renal function dictate elimination; clinical context: in normal renal function, excess fluids and electrolytes are cleared with a half-life of approximately 2-4 hours.
Renal excretion of water and electrolytes; dextrose is metabolized to CO2 and water. >90% of water and electrolytes are excreted renally; dextrose is fully metabolized.
Renal: >90% of infused electrolytes and water are excreted unchanged in urine. Biliary/fecal excretion is negligible (<1%).
