Negative pressure wound therapy vs conventional wound treatment in subcutaneous abdominal wound healing impairment. The SAWHI randomized clinical trial. JAMA Surg 2020; 155: 469-478.

Published: 7th April 2021

Authors: Seidel D, Diedrich S, Herrle F, Thielemann H, Marusch F, Schirren R et al.

Conclusion

A total of 507 patients undergoing abdominal surgery were studied. Use of the vacuum dressing reduced time to wound closure (36.1 versus 39.1 days, P<0.001), but increased the risk of wound-related adverse events: risk ratio 1.51, 95 per cent confidence interval 0.99 to 2.35.
