A multiple electrolyte, isotonic, crystalloid solution for intravenous infusion containing sodium chloride, sodium gluconate, sodium acetate, potassium chloride and magnesium chloride, which can restore electrolyte balance, normalize pH, and provide hydration. Upon intravenous administration, the balanced crystalloid solution will replace lost body fluids and electrolytes thereby providing hydration, normalizing electrolyte concentrations and regulating acid-base balance.
