Arista (Arista™AH) is a synthetic hemostatic agent that includes an
absorbable hemostatic powder consisting of Microporous Polysaccharide
Arista is indicated in surgical procedures as an adjunctive hemostatic
material in the control of capillary, venous and arteriolar bleeding.
How does it work?
Arista works through accelerating the intrinsic clotting cascade. When
applied onto a bleeding wound, Arista particles act as a molecular
sieve, and extract the fluid from blood. This osmotic action causes the
particle to swell and concentrates serum proteins, platelets and other
formed elements on its surface. The particles and their coating of
compacted cells create a scaffolding for the formation of a tenacious
fibrin clot within minutes of application. The Arista™AH particles are
fully absorbed and enzymatically cleared from the wound site within 24
to 48 hours.
What are the pros and cons?
Arista is synthesized from a purified plant polymer and free of all
biological components. It is non toxic, non irritating, non hemolytic
and non mutagenic. Arista has no adverse reactions.
How to apply?
Arista is a sterile powder, and is applied to the bleeding
site using its applicator. No mixing, no additional components and no
special storage conditions are required.
