IV therapy, or intravenous therapy, is a medical treatment that delivers fluids, medications, and nutrients directly into a person's bloodstream through a small tube called a catheter. This method allows for rapid absorption and is often used in hospitals for patients who are unable to take medications orally or need immediate hydration and support. Common uses of IV therapy include treating dehydration, administering antibiotics, and providing essential vitamins and minerals. It is also utilized in chemotherapy for cancer patients and during surgery to maintain fluid balance. Overall, IV therapy is a vital tool in modern medicine for effective patient care.
