What is the minimal daily treatment time for traumatic edema?

• A. 1 hour
• B. 2 hours
• C. 3 hours
• D. 4 hours

Answer: (B)

Traumatic edema responds best when edema-control methods are applied consistently over a total daily period that’s long enough to influence fluid movement but not excessive. The minimal total time for daily treatment in this scenario is two hours. This duration provides enough cumulative exposure to strategies that promote drainage and limit inflammation—such as cryotherapy to reduce capillary permeability, elevation above heart level to assist venous return, and compression to limit accumulation—while allowing rest and tolerable pacing of sessions.

In practice, you can achieve two hours by several short sessions (for example, multiple 15–20 minute ice blocks with elevation and compression in between) or a couple of longer blocks as tolerated. Less than two hours may be insufficient to meaningfully reduce swelling; more than two hours isn’t typically necessary and might cause discomfort or fatigue.
