Figure 2

The area of petechial bleeding following NPWT at -120 mmHg after 12, 24, and 48 hours, with conventional NPWT and NPWT with a protective disc inserted between the intestines and the vacuum source. Results are presented as the mean of 6 values ± SEM. Statistical analysis was performed using the Mann-Whitney test. Significance was defined as p < 0.05 (*), p < 0.01 (**), p < 0.001 (***) and p > 0.05 (not significant, n.s.). The area of petechial bleeding was smaller when a protective disc was used during NPWT.
