My grandfather has colon cancer and today they will hook him up to some sort of "Box" with Chemo medication in it that will be administering the Chemo for 2 days. So he doesnt have to make a trip to the hospital on Sunday, they okay'd for me to deaccess the port o cath. My question is....I have seen it done before and they flushed it with Heparin I believe. I will not flush it, I will only deaccess it. Will it be okay? Is they anything I should know? Thanks!
