Topical hemostatic agents are substances applied directly to a wound to help control bleeding. They work by promoting blood clotting and can be used in various medical settings, including surgeries and trauma care. These agents come in different forms, such as powders, gels, or dressings, and are designed to enhance the body's natural clotting process. Common types of topical hemostatic agents include collagen, gelatin, and chitosan. Each type has unique properties that make it effective in different situations. These agents are particularly useful in managing minor to moderate bleeding when traditional methods, like direct pressure, are insufficient.
