What Is Negative Pressure Wound Therapy?
Eastman: Negative pressure wound therapy is controlled suction, which is applied to a wound in order to stimulate healing. By applying controlled negative pressure to a wound excessive fluids are removed, cells are stimulated to proliferate, angiogenesis is accelerated, and the sustained contraction helps to draw the wound closed. As we discussed earlier, this is another therapy has it’s roots in the very distant past. Ancient Egyptian practitioners used a similar form of suction to draw toxins out of wounds. They placed an inverted cup over the wound and heated the air inside the cup with a candle. This warmed trapped air likely provided modest negative pressure to the area under the cup. Negative pressure wound therapy has been proven effective in both chronic and acute wounds, but, like any therapy or treatment, is not indicated for every wound. As I always emphasize, every person and every wound is unique. Wounds1: How does the technique work? Eastman: Negative Pressure Wound Thera
