The Hemostatic and Wound Healing Effect of Chitosan Following Debridement of Chronic Ulcers

Chitosan has been proven to be helpful in wound care as a hemostatic agent. The hemostatic effect is due to the positively charged chitosan interacting with negatively charged red blood cell membranes, initiating the agglutination of red blood cells and platelets. This promotes the activation of thrombin, which activates the clotting pathway, leading to thrombus formation. Objective. Based on the properties of chitosan as a rapidly acting hemostatic agent, the authors sought to determine if a chitosan gelling fiber wound dressing could control bleeding of freshly debrided wounds. The effect of the chitosan dressing on overall healing and patient and provider satisfaction was also evaluated. Materials and Methods. Wounds of any etiology requiring sharp debridement in patients older than 18 years who were capable of consent were eligible. Wounds were sharply debrided by curettage … read more
