When should warm compresses be applied when treating a hematoma?

Applying warm compresses after ice therapy is a recommended practice for treating a hematoma. The initial use of ice helps to reduce swelling and numb the area, providing immediate relief. After about an hour of applying ice, transitioning to warm compresses can promote blood circulation and facilitate the absorption of the accumulated blood in the tissue. The heat from the warm compress helps to relax the muscles and aids in the healing process by reducing pain and discomfort associated with the hematoma.

Using warm compresses immediately after the IV placement may not allow for proper initial management of inflammation and swelling, which can occur right after trauma. Waiting until there are signs of infection before applying warmth is also not advisable, as the primary goal is to manage the hematoma before it potentially worsens. Marking the border of the hematoma is important for monitoring its progression, but it does not guide the timing for the application of warm compresses in treatment.
