5-18. CHITOSAN DRESSING
Chitosan (ki' to san) is a polysaccharide found in shrimp shells. It has been
incorporated into a dressing that will effectively stop arterial hemorrhage. When
chitosan comes in contact with blood or other body fluids, it becomes extremely
adhesive and works like super-glue to plug the holes in the injured blood vessels. It
does not cause the blood to clot. Apply the chitosan dressing using the following steps.
The chitosan dressing is used to control serious arterial bleeding. The
chitosan dressing is not used for wounds with minimal to moderate
bleeding. The chitosan dressing can be used in conjunction with a
tourniquet to control severe arterial bleeding.
