IV fluids, or intravenous fluids, are liquids given directly into a person's bloodstream through a small tube called an IV. They are used in hospitals and clinics to help patients who are dehydrated, need medication, or require nutrients. Common types of IV fluids include saline, which is a saltwater solution, and dextrose, which provides sugar for energy. These fluids are essential for maintaining proper hydration and electrolyte balance in the body. Medical professionals carefully choose the type and amount of IV fluid based on each patient's specific needs, ensuring they receive the right treatment for their condition.
