Negative-Pressure Wound Therapy in a Pseudomonas aeruginosa Infection Model

Figure 1

The concentration of exotoxin A in the Pseudomonas aeruginosa-infected wound samples significantly differed between the control group (treated with a gauze dressing) and the negative-pressure wound therapy- (NPWT-) treated group at days 4, 6, and 8 (days 4 and 6, ; day 8, ). In the control group, the concentration of exotoxin A significantly decreased at days 4 ( versus days 0 and 2), 6 ( versus day 0), and 8 ( versus days 0, 2, and 4). In the NPWT group, the concentration of exotoxin A significantly decreased at days 2 ( versus day 0), 4 ( versus days 0 and 2), 6 ( versus days 0, 2, and 4), and 8 ( versus days 0, 2, 4, and 6). . Data are presented as mean ± standard deviation (). NPWT, negative-pressure wound therapy.
