A Prospective Randomized Study The Usefulness and Efficacy of Negative Pressure Wound Therapy with Lipido-Colloid Polyester Mesh Compared to Traditional Negative Pressure Wound Therapy for Treatment of Pressure Ulcers

To improve healing of pressure ulcer wounds, it is important to optimize the conditions
of the area surrounding the wound. Negative pressure wound therapy (NPWT) promotes wound
healing, however, the removal of NPWT can cause pain or focal bleeding, delaying wound healing or
causing infection. In this study, we reviewed the e cacy of the lipidocolloid non-adherent dressing
(Urgotul®) as a wound contact layer. A total of 38 patients from the same facility who applied
NPWT from April 2016 to October 2019 were included and divided into two groups; NPWT with
the lipidocolloid non-adherent dressing (group 1, experimental group, 19 patients) and NPWT only
(group 2, control group, 19 patients). The condition of the wound was examined prior to NPWT
application, at one week, and again at three weeks after application. No significant di erences were
found between groups for general characteristics, bacterial culture or photo analysis. However,
when comparing groups based on the time of examination, there was a significant reduction of the
wound size in group 1 (p = 0.001) but not in group 2 (p = 0.082). Therefore, the current study finds
that using the lipidocolloid non-adherent dressing as a wound contact layer in NPWT stimulates
healing by shrinking the size of the pressure ulcer wound.
