joshua5 -> wound care epithelial tissue (June 1, 2007 4:09:00 AM)

ok, what's epithelial tissue and what's slough?

my perception is that epithelial tissue is a very thin or pink tissue layer that covers a healing wound whereas slough is dead yellow crap that sits in a wound and needs to be removed manually or enzymatically. how'd i do for bare bones definitions? thanks for any replies.

I'm assuming it's a decent wound since you are treating it. Most likely, there is very little epithelial tissue present in the wound. The first "new" tissue is granualation tissue which is highly vascularized. Therefore it's red and graining in appearance. Slough can be many colors depending on what is "sloughing" off. If you get blood, it's not slough, lol.

epithelium is "the surface tissue" whether that be in inside of an organ (bladder transitional epithelium), the stratified squamous of skin or the epithelium lining the esophagus.

"slough" is a cellular matrix of nonviable epithelium, fibrin, and other cells that likely provide a protective coating until necessarily removed.

jason,
not treating, just trying to learn. as i understand it, eschar is brown/black and typically dry whereas slough is yellow/tan/green/white and more moist than eschar. is this true? is there ever clinically a synonymous use of the terms? reason i ask is that i think there's some misdocumentation at one of my sites.

another question... is it possible that you can't always observe epithelial tissue in a healing pressure ulcer? i.e. usually just see granulation tissue. i've seen the pinkish layer of epithelial tissue over a healing venous ulcer but not sure i've ever seen it on a healing sacral ulcer.
