What are potential complications associated with Arista AH?

• A. Only wound staining.
• B. Local skin irritation is the only potential issue.
• C. Infection at the site.
• D. Airway obstruction if aspirated; local inflammatory or foreign-body reaction; granuloma formation; infection; rare embolic events.

Answer: (D)

Arista AH is a starch-based hemostatic agent used to control bleeding, but its presence in tissue can trigger a range of adverse effects. The most complete set of potential complications includes airway obstruction if material is aspirated; local inflammatory or foreign-body reactions; granuloma formation; infection at the site; and, though rare, embolic events. This reflects how the material can remain in the wound, provoke a persistent inflammatory response, or migrate into airways or vessels in some cases. Other options miss these broader risks by focusing on a single issue or underestimating the potential for granulomatous or infectious complications. In practice, careful handling to remove excess material, avoiding intravascular use, and ensuring no material is left behind can help mitigate these risks.
