The Role of Negative Pressure Wound Therapy with Instillation and Dwell Time in the Preparation of Wound Bed.
Although the negative pressure wound therapy is a time tested method of wound preparation, the role of NPWT with instillation and dwell time in decreasing the downtime of wound preparation needs to be evaluated.
The objective of this study is assess the role of NPWTi-d in wound bed preparation.
NPWT was applied with the help of sterile polyurethane sponge and two tubes. The antimicrobial solution used was ionic silver solution, just enough to wet the sponge completely and up to the point when the transparent occlusive covering begins to lift. The wound was bathed with ionic silver solution and it was allowed to stay in the wound for 10-minutes, after every 2-hours of negative pressure application.
This was continued for 1-week. The dressing was opened at the end of 1-week, wound irrigated with normal saline, exudate swabs for culture taken and debrided, following which fresh NPWTi-d was applied. Its efficacy in preparing any wound for the definitive treatment or its role as a bridging procedure is well-known. But, the modifications of negative pressure wound therapy is comparatively new.
Negative pressure wound therapy was applied with the help of sterile polyurethane sponge and two tubes. The tubes
were inserted longitudinally into the sponge. Before NPWTi-d, the wound was thoroughly debrided and meticulous hemostasis was achieved. Then the wound was covered with a sterile Vaseline gauze.
