This document discusses electrolyte replacement therapy. The main purpose of electrolyte replacement therapy is to overcome electrolyte imbalances and restore body fluid composition and volume. Electrolyte imbalances can occur due to conditions like diarrhea, vomiting, dehydration, or prolonged treatment without nutrients. There are several electrolytes in the body like sodium, potassium, phosphate, bicarbonates, sulfate, calcium, chloride, and magnesium that are responsible for different body actions. Examples of compounds used for electrolyte replacement include sodium chloride, potassium chloride, and calcium lactate.
