METHODS AND COMPOSITIONS FOR ACHIEVING HEMOSTASIS AND STABLE BLOOD CLOT FORMATION

ActiveDK4403194T3facilitate hemostasis more slowlyRapid hemostasis
Provided is a tunable biopolymer hydrogel produced from two processed natural polysaccharides for use as a hemostat. If desired, the hydrogel formation can be tuned so that the hydrogel forms within seconds when applied to a tissue lesion. The resulting hydrogel can adhere to tissue and, without swelling, produce hemostasis within seconds after application to tissue of interest. The hydrogel also captures, aggregates and concentrates platelets and red blood cells at the site of the tissue lesion thereby initiating a clotting cascade at the site of the lesion. The hemostat can be used to prevent blood loss during surgical procedures, for example, during brain, spine or other surgical procedures where hemostasis is desirable, and is particularly useful during surgical procedures where swelling of the hemostat (e.g., in the brain or spine) would be detrimental to the subject.
