    Hi Sarah,

    We primarily use 20G needles for our ports. As long as the needle is a non-coring needle the life of the port should not lessen with 20G vs. 22G. For our patients who need to be phlebotomized we use a 19G and for our smaller patients if need be we can use a 22G.

    Hope this helps.

    it will be very much appreciated to share with me the appropriate implanted port size
    do you use the needle gauge 20 or gauge 22
    do you have a guidelines on when to use what in your policies?
    I read that we need to  Always use the smallest noncoring needle necessary to accommodate the infusion to prolong the life of the port and lessen the amount of pain experienced by the patient. However if the patient has deep ports do you still use a small gauge example gauge 22?
    or you put a gauze 20 ?

    Appreciate many responses to decrease the risk of extravasations and dislodgment

    Thank you in advance,
