    Peripheral venous cannula

    peripheral venous catheter (PVC or peripheral venous line or peripheral venous access catheter) is a catheter (small, flexible tube) placed into a peripheral vein in order to administer medication or fluids.

    A peripheral venous catheter is usually placed in a vein on the hand or arm. It should be distinguished from a central venous catheter which is inserted in a central vein (usually in the internal jugular vein of the neck or the subclavian vein of the chest), or an arterial catheter which can be placed in a peripheral as well as a central artery. In children, a local anaesthetic gel (such as lidocaine) is applied to the insertion site to facilitate placement

    Indications

    Repeated blood sampling
    Intravenous fluid administration
    Intravenous medications administration
    Intravenous chemotherapy administration
    Intravenous nutritional support
    Intravenous blood or blood products administration
    Intravenous administration of radiological contrast agents for computed tomography, magnetic resonance imaging, or nuclear imaging

    Contraindications

    No absolute contraindications to intravenous cannulation exist.

    Peripheral venous access in an injured, infected, or burned extremity should be avoided if possible.

    Complications

    Infection, phlebitis, extravasation, infiltration, air embolism, hemorrhage (bleeding) and formation of a hematoma (bruise) may occur.
