After the PD catheter fell out of my shirt and was dangling down during a yoga class, I started wearing spandex camisoles under my shirt. could just keep the tube tight to my body without fear of flopping out. Like a Spanx tank but not as tight. I have about a dozen, all colors. got them at Nordstroms. Even after transplant I have been wearing them, I feel like they keep the bandage over my scar (that took its time to heal, had to have wound pump, etc) from peeling off when moving around.I couldn't stand the PD catheter belt they gave me, but maybe my body shape was the problem.
I used a split 2x2 right up around the tube to keep antibiotic ointment off my clothes, then covered that and beginning of tube with 4 x 4 piece of Medipore tape--fabulous stuff I bought on Amazon that sticks well but doesn't pull your skin or cause allergic dermatitis. then I stuck the cap into my bra (was told not to, but everybody does it) and then the tight camisole--viola.I think some people with old tubes don't use any gauze or antibiotic ointment, but I did for the 2 years I was on PD. I think you would really like the medipore tape-very comfortable and not itchy/rashy at all.
