What can a clinician do to control a hematoma?

To control a hematoma effectively, applying ice is a widely accepted method. Ice helps constrict blood vessels, reducing blood flow to the affected area, which can limit the size of the hematoma and minimize swelling. The recommended duration of 2 minutes aligns with practices designed to reduce swelling quickly and effectively without causing tissue damage or discomfort.

While heat is used in some contexts to promote healing and relieve pain, applying heat to an acute hematoma can exacerbate bleeding and increase swelling due to vasodilation. Therefore, it is generally not advisable immediately after the injury. Alternating heat and ice may lead to confusion about the appropriate treatment protocol in the acute setting of a hematoma, especially if it's done without proper timing or awareness of the condition's progression.

In summary, the most appropriate immediate action for managing a hematoma is the application of ice.
