Query: Avant Gauze Drain Sponges

I use the drain sponges on my wife's feeding tube. I have used the Kendall Excilon Drain Sponges for a year with no problem. To save money I decided to change to the Gauze Drain Sponges. After just a couple of days use I noticed increased bleeding and irritation. The Gauze Drain Sponges may work well in different applications, in my case it was wasted money.
