    ​Hi Ashley,

    We dose TPA according to patient weight (see below). We also give 2mg/2ml for ports but the patient needs to be >10kg. We are able to redose a second time if after 2 hours the initial dose doesn’t work.

    It makes sense to give a 0.33mg/0.33ml (length + 10%) or standard 0.5mg/0.5ml dose for a catheter length/reservoir of 0.3ml. – correction on dosing

    a. Patients <10 kg: 0.5 mg/0.5ml
    b. Patients 10-30 kg: 1 mg/1 ml
    c. Patients >30 kg: 2 mg/2ml
    d. Implanted ports in patients >10kg: 2mg/2ml

    Hope this helps,
    Lou

    Can anyone share their policy on TPA administration? Specifically dosing for ports and broviacs/piccs?
    Previously we administered 2m/2ml for all ports. However, we have had quite a few mini ports placed recently and they have a 0.3ml reservoir. I have been working with pharmacy and we wanted to reach out to other institutions to see if you use a standard dose for ports or do you dose based on size of port?

    Thank you!
    Ashley
