If a G-SUC or VAC dressing cannot be maintained because of either persistent fluid or suction leaks, the attending physical therapist will attempt to reinforce the dressing. If after 2 attempts per 24-hour period, the dressing still cannot be maintained, that patient will be considered to have failed negative pressure wound therapy. Patients who fall into this category will be able to crossover into the other treatment arm, but additional data regarding their treatment will not considered in the results of the study.
