The more I think about this the more I believe that a fully healed exit site does not need a dressing although I can't bring myself to go without one just yet. I've seen posts on this site refering to tunnel infections but as far as I understand it the 'tunnel' heals tightly round the tube so any infection at the exit site would have to be very severe and neglected to get though a fully healed tunnel. I may be wrong about this because in the 12 months that I've been on dialysis we havn't had any really hot weather in the UK (wow I wish) so there's never been the kind of temperature to make me sweat. As for the tape, I don't seem to have a problem with it skin wise. In the UK we clean the site with some foul smelling stuff called Betadine (hospital smell in a bottle I call it. Then wipe it down (not rinse) till it's dry, dab it with bactroban cream and then dress it. I think also in the UK because of widespread infection in hospitals they adopt a very strict heigene regime to create an extra wide margin against infection.
