(CS-012) Initial experience of a novel traditional Negative Pressure Wound Therapy dressing incorporating a distribution layer (tNPWT+DL†) in patients with surgical and traumatic wounds.

Traditional and single-use Negative Pressure Wound Therapy (tNPWT, sNPWT) are effective and widely used interventions used to manage a range of open wound indications, and closed incisions(1). In a randomized control trial comparing tNPWT with sNPWT^††, sNPWT^†† demonstrated superior outcomes including faster wound closure when used with and without a wound filler(2). These benefits are attributed to proprietary technology delivering a unique mode of action, distributing negative pressure across the wound and wider therapeutic zone incorporating the peri-wound area(3). Until now, this mode of action has been unique to wounds treated with sNPWT^††.

Methods:

These cases present the initial experience of a novel tNPWT+DL dressing^† incorporating this same proprietary technology. The dressing features a negative pressure distribution layer, and a silicone wound contact layer. This dressing was used to treat patients in the plastic surgery department with traumatic and surgical wounds as part of a real-world retrospective case study.

Results:

This novel tNPWT+DL dressing^† has made application of therapy simple with the addition of a pre-cut hole for the port, a modifiable dressing which can be cut to increase conformity in challenging anatomical locations or around orthopaedic external fixation devices and the addition of the silicone contact layer which allows repositioning at dressing changes, and patient comfort. Wound progression was evident, with reduction in wound size and healthy granulation. Edema control was also noticeable as was the health of the periwound skin and wound.

Discussion:

These cases represent some of the first applications of this unique tNWPT+DL dressing^† with an integrated distribution layer and silicone wound contact layer. They demonstrate a unique mode of action providing a wider therapeutic zone of therapy successfully integrated into a tNPWT dressing showing enhanced wound outcomes.
