<qa>  What is the purpose of the study?Application of the VAC device may significantly decrease the incidence of draining hematomas that require surgical irrigation and debridement. The aim of this project is to perform a prospective, randomized study evaluating the VAC negative pressure device as a treatment for draining hematomas. We will also analyze the cost of treating a hematoma with a VAC compared with currently employed treatments. Additionally, we will document the incidence of infection of the hematoma with and without use of the VAC device.
