    These are the steps you should do to insert an intravenous cannula , read it carefully then watch a sample video in the bottom:

    1- Introduce yourself to the patient. Explain the procedure to the patient and gain informed consent to continue. It is also worth explaining that cannulation may cause some discomfort but that it will be short lived.

    2-
    Ensure that you have all of your equipment ready as follows:

    • alcohol gel
    • gloves
    • an alcohol wipe
    • a tourniquet
    • an IV cannula
    • a suitable plaster
    • a syringe
    • saline
    • a sharps box

    3- Sanitise your hands using alcohol cleanser.

    4- Position the arm so that it is comfortable for the patient and identify a vein.

    5- Apply the tourniquet and re-check the vein.

    6-
    Put on your gloves, clean the patient’s skin with the alcohol wipe and let it dry.

    7-
    Remove the cannula from its packaging and remove the needle cover ensuring not to touch the needle.

    8-
    Stretch the skin distally and tell the patient to expect a sharp scratch.

    9-
    Insert the needle, bevel upwards at about 30 degrees. Advance the needle until a flashback of blood is seen in the hub at the back of the cannula

    10-
    Once this is seen, progress the entire cannula a further 2mm, then fix the needle, advancing the rest of the cannula into the vein.

    11-
    Release the tourniquet, apply pressure to the vein at the tip of the cannula and remove the needle fully. Remove the cap from the needle and put this on the end of the cannula.

    12-
    Carefully dispose of the needle into the sharps box.

    13-
    Apply the plaster to the cannula to fix it in place.

    14-
    Check that the use-by date on the saline has not passed. If ok, fill the syringe with saline and flush it through the cannula to check for patency.If there is any resistance, if it causes any pain, or you notice any localised tissue swelling; immediately stop flushing, remove the cannula and start again.

    15- Finally, ensure that the patient is comfortable and thank them.

    Note that as an extension to procedure, you may be asked to set up an IV drip.
