As Dr. Bell notes, VAC therapy and other systems both remove exudates but the similarity ends there. Citing a recent published panel case study series, Dr. Bell notes that researchers were unable to conclude that another brand of NPWT showed evidence to support its use in wound healing.1 He says the sponge used in VAC therapy has proven to be superior to gauze as an interface to the wound bed. Gauze tends to absorb exudates and keep them in contact with the wound while the foam, due to its design and fluid repelling properties, allows for more efficient removal of exudates, according to Dr. Bell.
“Bottom line, there is not a significant body of evidence supporting other NPWT systems in comparison to the large body of evidence that supports the use of VAC therapy,” summarizes Dr. Bell.
Dr. Bell is a board certified wound specialist of the American Academy of Wound Management, and a Fellow of the College of Certified Wound Specialists and the American Professional Wound Care Association.
