Intravenous (IV) refers to the administration or delivery of fluids, medications, or nutrients directly into a patient's veins. It is a medical procedure primarily used when immediate and effective systemic delivery is needed.
Administering substances intravenously involves inserting a sterile hollow needle, known as a catheter, into a vein. The catheter is then connected to an IV tubing system that allows the transfer of fluids or medications directly into the bloodstream. Intravenous administration ensures rapid absorption and distribution of the substance throughout the body, bypassing the digestive system.
Intravenous therapy plays a crucial role in various healthcare settings, including hospitals, clinics, and emergency situations. It is commonly employed for hydration purposes, blood transfusions, delivery of medications, chemotherapy, or nutritional support. Intravenous fluids may include saline solutions, glucose solutions, or a combination of electrolytes and water.
While intravenous administration provides numerous benefits, it also carries potential risks, such as infection, vein irritation, or adverse reactions to the substances being administered. Therefore, it requires careful and skilled healthcare professionals who are capable of accurately prescribing the appropriate dosage, selecting the right type of IV solution, and monitoring the patient's response during the procedure.
Overall, intravenous therapy serves as a vital component in modern medicine, ensuring the efficient delivery of critical substances directly into a patient's bloodstream, allowing for immediate absorption and targeted effects.
