Hi Chris, although my stoma is an outie, this is what I do when I change the wafer. I had some irritation around the stoma after surgery and a wound care nurse suggested this process to me.
Clean the area with cool water.
Let it dry completely. I have a small fan that I use. If the stoma is percolating, I tuck in a plastic grocery bag into my slacks/underwear to prevent a mess.
On the irritated skin, I use ostomy powder and work it around the skin next to the stoma. It absorbs the moisture. Then, I use a skin barrier wipe over the powder to create a crust. I let it dry completely.
I repeat this process once again.
Then, I place my wafer on the completely dried area.
Next step, I use a q-tip to run it around the wafer on the part between the stoma and the plastic/snap on part. My wafer is small so I can't use my finger.
After I do that process for about a minute or two, I attach the pouch and lie down for 5 minutes to warm the wafer. I was told that it makes the wafer stick better to the skin.
I also change the pouch every day and check around my stoma. I clean out the debris each morning with a q-tip and a wet paper towel gently and sprinkle some ostomy powder around the stoma to absorb any excess moisture. Once in a while, my stoma bleeds...it may be the paper towel or because I rubbed my stoma by accident.
Hope this helps. Everyone here has very good suggestions and if this one is not helpful maybe another post will be.
Good luck. Keep posting. LH
