Which statement best describes the difference between acute and chronic edema management strategies?

• A. Acute edema uses cryotherapy and compression; chronic edema uses manual lymph drainage only
• B. Acute edema uses cryotherapy and compression; chronic edema uses lymphatic drainage techniques and compression with graduated garments
• C. Acute edema uses heating; chronic edema uses ice
• D. Acute edema uses compression; chronic edema uses elevation

Answer: (B)

A key distinction in edema management is how treatment targets the swelling at different stages: acute edema aims to limit inflammation and fluid leakage, while chronic edema focuses on moving and maintaining fluid away from tissues over the long term. In the acute phase after injury, cryotherapy (ice) helps reduce vasodilation and capillary permeability, which diminishes swelling and pain, and compression helps limit fluid accumulation and supports the tissues. Elevation is often used as an adjunct to further reduce edema.

In chronic edema, the priority shifts to enhancing lymphatic drainage and maintaining the reduction with ongoing compression. Lymph drainage techniques (manual lymph drainage or other lymphatic therapies) actively promote fluid movement through the lymphatic system, and graduated compression garments provide a sustained pressure gradient to prevent re-accumulation of fluid.

The other options either oversimplify chronic edema by suggesting MLD alone without compression, or swap heating for cooling, or imply that chronic edema relies on elevation alone.
