The military is interested in finding a hemostatic dressing that is effective in controlling hemorrhage from combat wounds, relatively inexpensive, and easy to transport. The fibrin dressing has existed for decades, but the military has been reluctant to use the dressing because it is not Food and Drug Administration approved, fairly expensive, and difficult to apply on certain wounds. Newer dressings such as the microporous polysaccharide hemosphere (TraumaDEX), mineral zeolite (QuikClot), poly-N-acetylglucosamine (HemCon), and microporous hydrogel-forming polyacrylamide (BioHemostat) dressings have addressed these deficiencies in that they are relatively inexpensive, easy to transport, and easy to apply. However, the effectiveness of these new dressings on wounds sustained in combat is still questionable according to studies and anecdotal reports from Operation Iraqi Freedom. More research is needed to draw definite conclusions about the effectiveness of these dressings in a combat setting.
