Combination of negative pressure wound therapy and acoustic pressure wound therapy for treatment of infected surgical wounds: A case series

The optimal wound therapy for healing infected wounds post surgery or surgical debridement has not been established. Negative pressure wound therapy and acoustic pressure wound therapy are advanced wound-healing modalities that apply forms of mechanical pressure to wound tissue in an effort to promote healing by stimulating cellular proliferation. Using a combination of negative pressure wound therapy and acoustic pressure wound therapy was evaluated in a series of six patients with large, infected surgical wounds presenting with moderate to large amounts of serosanguineous drainage. After concurrent treatment with both modalities (range: 4 to 12 weeks), wound volume was reduced by 99% to 100% in all wounds except one wound for which depth at end of treatment was not measurable due to hypergranulation. Similarly, wound surface area was reduced by 82% to 100%, with the exception of the hypergranular wound, which decreased in size by 60%. Serosanguineous wound drainage was reduced in four wounds and remained unchanged in two wounds.
