Sirimaharaj W 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.
Objective: Carryout a pilot clinical comparative study of Chitin-PAA dressing, lipido-colloid absorbent dressing, and alginate
wound dressing in the treatment of partial-thickness wound.
Material and Method: Between June 2006 and March 2007, 36 partial-thickness wounds were randomized into three groups
and three different types of dressing were used. Each wound was treated until it was completely healed, and a visual analogue
scale was used for the pain evaluation.
Result: The present study shows the visual analogue pain score in the Chitin-PAA group seems to be a bit higher than the
Urgocell® group but not statistically different. The completely healed day is not significantly different. Three patients in the
lipido-colloid absorbent dressing groups had wound infection but eventually healed after treatment.
Conclusion: There was no statistical difference in terms of visual analogue pain score and healing time between the lipidocolloid
absorbent dressing, alginate dressing, and chitin-PAA dressing.
