Description
An IV cannula (intravenous cannula) is a small, thin tube that is inserted into a vein to provide access for the administration of fluids, medications, and blood products. The cannula is composed of a small plastic tube with a sharpened tip, which is inserted into a vein and then secured in place with adhesive or a suture. It is available in different sizes and is commonly used in hospitals, clinics and at home for administering long-term IV therapy.
It is inserted by a trained healthcare professional and it is usually inserted in the hand, arm, or foot and can be used for days or weeks. The insertion site is usually covered with a sterile dressing to keep it clean and to prevent infection. It is important to monitor the site for signs of infection or complications such as swelling, redness, or bleeding. The cannula should be changed every 72 hours or as recommended by the healthcare professional.
