Hematoma (cont.)

Medical Editor:

What are the complications of a hematoma?

Hematomas cause swelling and inflammation. It is often these two consequences that cause irritation of adjacent organs and tissues and cause the symptoms and complications of a hematoma.

One common complication of all hematomas is the risk of infection. While the hematoma is made of old blood, it has no blood supply itself and therefore is at risk for colonization with bacteria.

Can hematomas be prevented?

Accidents happen and most hematomas are inevitable once the trauma has occurred.

For patients taking anticoagulation medications, it is wise to avoid participating in events with high risk of injury. For patients taking warfarin (Coumadin), it is important to make certain that the dosing is appropriate and the blood is not thinned excessively.
