The purpose of this study is to compare how well two methods (VAC and G-SUC) of securing skin grafts using negative pressure wound therapy work. Negative pressure wound therapy is a commonly used method of applying suction on wounds to remove fluid from wound and to promote healing. The VAC system is widely used and consists of a foam dressing and a portable computerized suction pump. The G-SUC method uses commonly available dressing supplies attached to vacuum (suction) pump located on the wall above a hospital bed. The investigators have frequently used both methods over the past 10 years and have not observed any specific negative side effects of either.
