After packing a wound with a hemostatic dressing, how long should pressure be maintained?

Maintaining pressure on a wound after applying a hemostatic dressing is critical for effective hemostasis and to ensure that bleeding is controlled. The recommended duration for applying pressure is typically around 3 minutes. This timeframe allows sufficient time for the hemostatic agent to activate and encourage clot formation, which is essential in preventing further blood loss.

If pressure is released too early, there is a risk that the clot may not have developed sufficiently, potentially leading to rebleeding, which could complicate the patient's condition. While shorter durations might seem practical, they generally do not provide adequate time for effective clotting with the help of the hemostatic dressing.

In contrast, while longer durations of pressure may seem beneficial, they can be impractical in a tactical environment where time and movement are essential. Adhering to the 3-minute guideline strikes a balance between ensuring effective bleeding control and maintaining operational readiness.
