We read with great interest the Viewpoint article entitled Simplified Negative-Pressure Wound Therapy System for Skin Graft Wounds.1 The authors describe an easy and simple method of using a negative-pressure system on skin grafts. The method, though simple in concept, has a few flaws.

We tried similar therapy and found that the system does not sustain negative pressure for more than 1 hour and needs regular recharging. This repeated manipulation is not only cumbersome but has a high chance of graft shear. This fluctuation in pressure is against the standard protocols used when negative-pressure therapy is applied following skin grafting.2,3 Negative-pressure therapy after skin grafting is generally maintained until the fourth postoperative day. This is intended to provide splintage of the graft like a tie-over dressing and thus avoid any shearing of the graft from the wound bed until the graft takes. Generally, negative-pressure dressings following skin grafting have minimal drainage from the wound site, especially from wounds as small as 5 × 5 cm. In the study, the need for 6-hourly evacuation of fluid from the syringe is surprising.

New innovations in negative-pressure therapy aim at a cost-effective method. This endeavor should not be at the cost of continuous reliable therapy.
