What is the time to achieve hemostasis in orthopedic and general surgery?

• A. 2 minutes.
• B. 4 minutes.
• C. 5 minutes.
• D. 6 minutes.

Answer: (C)

Time to achieve hemostasis measures how long it takes, after applying a hemostatic method, for bleeding to stop and a stable clot to form. In orthopedic and general surgery, a typical target window is about five minutes. This timeframe gives the agent and the surrounding tissue enough opportunity to interact and seal the vessel, while still keeping the pace of the operation practical and safe. If active bleeding persists after around five minutes, it’s a cue to reassess and escalate—reapply or use additional hemostatic methods, or turn to mechanical measures like cautery or ligation as needed. Shorter intervals, like two minutes, are often not reliable for many bleeds, while six minutes suggests the need for further intervention. Five minutes aligns with common practice and test expectations for when hemostasis should be achieved in these surgeries.
