What is the time to achieve hemostasis in cardiac surgery?

• A. 1 minute.
• B. 3 minutes.
• C. 5 minutes.
• D. 7 minutes.

Answer: (B)

Time to achieve hemostasis measures how long it takes after applying a hemostatic agent or performing a maneuver for bleeding to stop at the surgical site. In cardiac surgery, rapid control of bleeding is essential because ongoing blood loss lengthens bypass time and increases transfusion risk. Agents like Arista AH are expected to produce hemostasis within about three minutes, providing a practical target for surgeons. If bleeding stops in roughly three minutes, that supports effective use of the product in this setting. Taking only one minute is often not reliably achievable across all tissue surfaces, while taking five or seven minutes suggests the bleeding is not being controlled promptly and additional measures will be needed. If hemostasis isn’t achieved around three minutes, escalate with other techniques or sources of hemostasis.
