Comparative study between chitin/polyacrylic acid (PAA) dressing, lipido-colloid absorbent dressing and alginate wound dressing: a pilot study in the treatment of partial-thickness wound.

Background: Polyacrylic acid grafted chitin (Chitin-PAA) contains a hydrogel characteristic that makes it more suitable for wound dressing application. In animal models, Chitin-PAA dressing exhibited properties as a promising dressing. Epithelization promotion, rapid reduction of wound size, reduction of inflammatory cell response, and less toxicity had been noted.
