Hi Wattle
for the welcome.
I'm using about a 120mm x 50mm gauze over the exit site which anchors the tube to a certain degree and doesn't cause any irritation. I have then applied 3 strips of Yu-Ki Ban surgical tape supplied by Baxter to fix the rest of the catheter... it is this tape that comes off after a while under sweaty conditions... It doesn't irritate my skin however and works well otherwise.
I have planted 40 small scrubs this weekend and decided to only rely on the gauze over the exit site and tuck the end of the catheter into the top of my shorts. This was ok but I don't think I should do it regularly as there is the danger of have the catheter caught up on something!
I'll have to chase up a PD belt... I am not aware of them!
Breezysummerday, I might try the waterproof tape but will have to purchase some to try out. The gauze hasn't been coming off as long as I don't disturb it!
Thanks for your advice.
