Materials intended to be used in the emergency/trauma setting to promote localized coagulation in wounds by activating the body\'s clotting mechanism. Emergency/trauma hemostatic agents typically promote clotting by strongly adhering to tissues, creating a physical barrier to bleeding (i.e., mucoadhesive agents) and/or by absorbing the water content of blood, concentrating cellular and protein blood components that leads to clotting (i.e., factor concentrating agents). Emergency/trauma hemostatic agents consist of various active components (e.g., chitosan, hydrophilic polymer/potassium ferrate, plant-derived starch) and are supplied in a number of physical forms including loose powders or granules, powders or granules packaged in pouches, or gauze-like materials.
