How should Arista AH interact with irrigation or suction during use?

• A. Use minimal irrigation to keep the field dry; suction can be used but avoid drawing large amounts of powder into suction; do not pre-wet the powder.
• B. Use large irrigation and aggressive suction.
• C. Do not use suction at all.
• D. Pre-wet the powder before application.

Answer: (A)

Arista AH works by staying on the bleeding surface to form a physical matrix that helps clotting. To maximize this effect, apply it with minimal irrigation so the field stays relatively dry and the powder can adhere and concentrate at the site. Suction can be used, but do so cautiously; pulling large amounts of powder into the suction depletes the product from the target area and wastes material. Pre-wetting the powder is avoided because moisture turns it into a slurry that’s harder to control, more likely to wash away, and less able to stay in place on the bleeding surface. Using too much irrigation or aggressive suction would disrupt the powder’s ability to stay where it’s applied, while not using suction at all isn’t practical for keeping the field clear.
