Depending on the product you use, and the technique you use to remove the barrier and as Juliantheory151 said, how you apply the barrier can mean a world of difference.
Most 1 or 2 piece systems are designed to last for days without having to change them. And red irritated skin can be pain and as you know can be caused by fecal matter, the skin breaking down from frequent changes or even allergies.
I agree when the stoma is constantly having output, it can be a challenge to change your pouch or wafer. Marshmallows, as Julian suggested, can thicken loose stool along with other food products like rice, pretzels or cereal.
It would help to know where the leak is most frequent in your case, for example, under the wafer or around the weld? Do you use a 1 or 2 piece system? What is the technique you use to remove a pouch or wafer and what is the technique you use to apply one? Do you use a skin prep before applying the pouch or wafer? Does your stoma retract and go under the wafer?
There are several methods and lots of videos on YouTube on changing your pouch or wafer. Just some tips when changing.
When preparing to change, try to keep your stoma positioned either over your sink or toilet so that the mess is minimized. I fold up some tissue paper and place below the area of my stoma and keep myself right up against the sink.
When prepping a pouch or wafer, if you're cutting to fit, make sure you cut the hole for your stoma just wide enough as the widest part of your stoma so it has the freedom to expand and contract without difficulty and minimizes the peristomal skin from being to exposed to the acid in your output.
Take a washcloth and lather it up with warm water and a mild soap bar. With the soapy washcloth, gently push between the pouch/wafer and your skin. You don't want to rip off the pouch/wafer off as this irritates the skin even more and can leave parts of the wafer attached to your skin. The soap isn't going to hurt your stoma and can soothe irritated skin. I thoroughly soap up and wash all of the peristomal skin and gently clean my stoma. Some bleeding from around your stoma is normal.
Once you're satisfied with cleaning, rinse the soap out of the washcloth very thoroughly and wring it out. Use the damp cloth to wipe the soap completely away from your peristomal skin and stoma.
Now the next part, many people have different techniques. I myself take folded tissue and wrap the stoma in case it starts to spit....lol. Some people use condoms but I figure if it starts spitting, I can rinse the sink and wipe it down with Clorox wipes. Anyways, wrap the stoma in some fashion and pat dry the peristomal skin. You can also use the lower cool setting on a hairdryer to dry the skin thoroughly. Once it's dry, apply a skin barrier wipe and or stoma powder and let it dry so it's not tacky to the touch. Time it carefully and place the pouch or wafer over your stoma. Place your palms flat against the pouch or wafer on the left and right side of your stoma and hold in place for at least 30 seconds. Do the same with your palms flat against the wafer on the top and bottom of your stoma. Get the edges of your palms as close as comfortable to your stoma. This will heat activate the pouch or wafer and create a good seal.
If you use a 2 piece system, I would go ahead and attach the pouch to the wafer first before placing my hands over the wafer as to avoid a mess when trying to create a good seal. If done properly and there are no underlying issues (i.e. retracting stoma, weeping skin) the pouch or wafer will last for days.
This is the method that works best for me. Everyone will have their own tips and technique. You just have to find the right method for you. I hope this helps.
