NPTW is a very common procedure in Germany. We do it via VAC-therapy (Vacuum Assisted Closure) and it's pretty much the same as shown there. Even tho it has been simplified for this comic as there are more steps in regard of wound cleaning and Analysis. They normally do a swab for microbiological investigation to find out which pathogen caused the infection. They also clean the infected area before they flush out the wound and put a sponge inside the infected area.
