A composition is described in which chitosan is prepared in a foamed gel that may be layered onto a suitable backing for use as a wound dressing, or the gel may be directly applied to wounds to effect hemostatic activity as a result of the action of the chitosan. The composition of the foamed chitosan gel has added to it medicaments, which include antimicrobial agents, in order to reduce the risk of microbial infections in wounds where hemostatic agents including the chitosan foamed gel preparation can be applied to effect hemostasis. |
