IV fluids, or intravenous fluids, are sterile solutions administered directly into a person's bloodstream through a vein. They are commonly used in hospitals to provide hydration, deliver medications, and restore electrolyte balance. IV fluids can contain various components, such as saline, glucose, and electrolytes, depending on the patient's needs. These fluids are essential for patients who cannot drink enough fluids or require rapid treatment, such as those with dehydration, surgery, or severe illness. By using IV fluids, healthcare providers can ensure that patients receive the necessary nutrients and hydration quickly and effectively.
