Application of Negative Pressure Wound Therapy on Closed Incisions
Negative pressure wound therapy (NPWT) is widely used for chronic and acute open wounds, with clinically proven benefits of faster wound healing by promoting granulation tissue growth and increased perfusion and facilitating epithelialization and contraction. Improved outcomes on open wounds prompted the application of NPWT on closed surgical incisions. The application of NPWT, in the immediate postoperative period, reduces surgical site infections (SSIs) and wound dehiscence by 50% in high-risk patients. The negative pressure reduces wound edema and improves local perfusion and lymphatic f low, thereby minimizing hematoma and seroma rates. The improved perfusion and oxygenation facilitate quicker wound healing as well as minimize ischemic complications like f lap necrosis. Recent literature supports enhanced wound healing and superior scar appearance as well as improved wound maturity, evidenced by 50% more force required to pull apart a sutured incision. Improved outcomes of incisional NPWT are reported from various surgical procedures on abdominal, breast, orthopedic, vascular, cardiac, and plastic surgeries. Further clinical studies and cost-benefit analysis are needed to recommend routine postoperative use of incisional NPWT in high-risk and low-risk patient population.
