How should Arista AH be applied to a bleeding surface?

• A. Apply the powder by pouring a large amount onto the wound until it is completely filled.
• B. Apply small amounts with a brush in a sweeping motion.
• C. Apply the powder after soaking it in liquid to activate.
• D. Apply small amounts directly to the bleeding site using sterile forceps or an applicator; keep the field dry and avoid overpacking.

Answer: (D)

The technique relies on applying the hemostatic powder exactly where bleeding is happening, in small, controlled amounts, with a dry field. Use sterile forceps or an applicator to place the powder directly on the bleeding site. Keeping the surrounding field dry helps the material stay localized and visible, and prevents spreading or clogging from excess moisture. Avoid dumping a large amount or sweeping with a brush, and don’t overpack the wound—the goal is a precise, localized scaffold for clot formation without obscuring the view or crowding the area. Do not activate or moisten the powder before application; it should be applied dry and will interact with the blood at the site to aid hemostasis.
