Negative pressure darwinism: survival of the fittest paradigm

The use of negative pressure for wound healing has been based on a set of parameters and devices that until recently were combined into a single paradigm. Despite historical and more recent evidence providing viable alternative considerations, it is only recently that this paradigm and its tenets have come into question. As the understanding of the limits of the current paradigm and specific instances of its benefits and drawbacks are identified, shifts in the paradigm must take place if the therapy is to evolve, develop, and continue to be efficacious. The pertinence of the concept of survival of the fittest is used to explore the need for a paradigm shift in negative pressure wound therapy.
