bard power port

my surgery is scheduled on monday 2/18. does anyone have a port for chemotherapy still in place. i have mine still and am wondering how successful i might be in convincing the anestheologist to use my port as one iv entry. dr. moon requires two. dr. moon says he cant commit to that i will have to talk to the anesthesologist myself. we all know how that goes. you cant get by the nurse who wants to run the two iv's. my veins are terrible and collapse from chemo. anyone else have this same problem? thanks in advance
