Subjects included in the control (standard closed suction drains) and experimental arms (NPWT device) of each procedure group will not experience risks to subject privacy, discomforts, or inconveniences associated with participating in this research project that they would not otherwise experience with the use of standard closed suction drains currently being used for post-operative wound care. These standard risks, discomforts, and inconveniences include the potential for bleeding from drain site, infection at drain site, requirement of changing collection vessel when full, and pain. The post-operative ultrasound evaluation is also non-invasive. It is an evaluation which is often performed on patients in the post-operative period to assess for subcutaneous fluid collections.
