The choice of fluid depends on the patient's condition and specific medical needs:
- Dehydration: Crystalloids like normal saline or lactated Ringer's are often used to rehydrate patients. - Hypovolemia: Both crystalloids and colloids can be used to restore blood volume. In severe cases, blood products may be necessary. - Electrolyte Imbalances: Specific solutions like potassium or magnesium infusions can correct deficiencies. - Shock: In cases of septic or hemorrhagic shock, colloids or blood products may be more effective than crystalloids.
