What type of dressing contains an agent that promotes blood clotting?

Hemostatic gauze or dressing is specifically designed to promote blood clotting. It typically contains substances that enhance the body's natural clotting mechanisms, such as chitosan or kaolin, which help to rapidly control bleeding at the site of a wound. This type of dressing is particularly useful in trauma situations where significant blood loss could occur, allowing for faster stabilization of the patient until further medical help can be provided.

Other options such as regular gauze are mainly used for wound coverage and protection but do not have clotting agents. Adhesive bandages serve to cover small cuts and abrasions but do not possess features to promote clotting, focusing instead on protecting the wound from infection and further injury. Compression bandages are employed to apply pressure to a wound, which can help control bleeding, but they do not contain active agents specifically intended to enhance clot formation.
