Which dressing is impregnated with chitosan-based material to promote clotting?

• A. Combat Gauze
• B. ChitoGauze
• C. Celox Gauze
• D. X-Stat

Answer: (B)

Chitosan-based dressings promote stopping bleeding by a chemical interaction with blood cells. Chitosan is a positively charged biopolymer that binds to negatively charged red blood cells and platelets, helping them stick together and form a clot quickly. When a dressing is impregnated with chitosan, placing it on a bleeding wound allows this material to contact blood directly and rapidly initiate hemostasis, even in wet or actively bleeding conditions. ChitoGauze is specifically designed with chitosan-based material embedded in the gauze, so it activates clotting through this chemical mechanism rather than just providing physical pressure. Compared to this, other dressings work by different means. Combat Gauze relies on kaolin to activate the coagulation cascade, X-Stat pacifies the wound by expanding to apply pressure and tamponade, and Celox Gauze uses a different hemostatic agent with another mechanism. Because the defining feature here is the chitosan-based impregnation, the dressing with chitosan is the correct choice.
