Summary:
The use of negative pressure wound therapy (NPWT) as a bolster for split-thickness skin grafts has been well documented in the literature. It facilitates the removal of transudate, which can result in the formation of seroma, and mitigates shear stress, which can detach the graft from the underlying wound bed. Its widespread use may be limited by factors such as increased cost and length of hospitalization. Recently, mechanically powered devices (Smart Negative Pressure; Spiracur, Inc., Sunnyvale, Calif.) have been reported as showing promise in healing wounds with outcomes surprisingly comparable to standard NPWT in the populations studied. We are unaware of any reports in the literature that have detailed the use of a mechanically powered NPWT device as a postoperative bolster for split-thickness skin grafts.
