Effectiveness of Negative-Pressure Wound Therapy

This study aims to compare the effects of Negative-Pressure Wound Therapy and wet-to-dry dressing on Stages 3 and 4 pressure injuries, and to investigate the consistency of Three-Dimensional Wound Measurement Device findings with Pressure Ulcer Scale for Healing Tool scores. This study is a randomized controlled trial. A total of 30 patients with Stages 3 and 4 pressure injuries were included in the study. The patients were divided into two groups: the experimental group or Negative-Pressure Wound Therapy group and the control or wet-to-dry dressing group. All patients received 3 rounds of treatment. Data were collected with a Patient Identification Form, Pressure Ulcer Scale for Healing Tool and the findings of Three-Dimensional Wound Measurement Device. We found that granulation tissue formation was more significant in the experimental group (p \< .05), and that there was more significant wound shrinkage (p \< .05) with a more significant decrease in the Pressure Ulcer Scale for Healing Tool scores (p \< .05). The wounds were assessed with the Tool and the Three-Dimensional Wound Measurement device. Device measurements were found to be correlated with Pressure Ulcer Scale for Healing Tool Tool findings (p \< .05) There was a significant correlation between device-measured granulation findings and PUSH Tool score results of the experimental group's third measurements (p \< .05). We conclude that Negative-Pressure Wound Therapy is an effective treatment method for pressure injuries, and Three-Dimensional Wound Measurement device is an usable wound assessment tool.
