Is there a limit to how many times Tpa may be used
to open a blocked PICC line (or any other CVC for that matter)?
Since switching to Saline only flushes in our acute
care facility a short while ago, we have seen a great increase in blocked
lines --we do use a positive pressure cap but the staff does not always
use it correctly. We are continuing to emphasize
correct flushing protocol BUT in the meantime, is it contraindicated
to use Tpa to open a blocked line more than once in a short time( within 24 to
48 hours)?
