Peripheral Venous Catheterization is a medical procedure used to access a patient's veins for various purposes, such as administering medications, fluids, or drawing blood. This technique involves inserting a thin, flexible tube called a catheter into a peripheral vein, usually in the arm or hand. It is commonly performed in hospitals and clinics to provide quick and effective treatment. The procedure is typically done using a sterile technique to minimize the risk of infection. Once the catheter is in place, it can remain for several days, allowing for repeated access without the need for multiple needle sticks. Proper care and monitoring are essential to ensure the catheter functions effectively and safely.
