NCT03815240

Brief Summary

Skin functional parameters such as erythema or stratum corneum hydration have been successfully used in PU prevention research. These parameters are able to discriminate effects of different loading intensities and to measure PU preventive device performance. The overall aim of this study is to measure the effects of Mepilex® Border Sacrum Dressing on the skin structure and function during mechanical loading compared to (1) no dressing, (2) ALLEVYN Life Sacrum Dressing and (3) Optifoam® Gentle Liquitrap Sacrum Dressing.

Outcome Measures

Primary Outcomes (7)

  • Change in Skin Surface Temperature From Baseline

    A skin thermometer based on infrared technique (Courage and Khazaka Electronic GmbH) was used to measure the skin surface temperature at the sacrum

    Change from baseline after 3.5 hours loading period at visit 1 (Day 0), visit 2 (not before 3 weeks after visit 1), visit 3 (not before 3 weeks after visit 2), visit 4 (not before 3 weeks after visit 3).

  • Change in Stratum Corneum Hydration (SCH) From Baseline

    Corneometer CM 825 (Courage and Khazaka Electronic GmbH) was used to measure the stratum corneum hydration (SCH) at the sacrum in arbitrary units (AU) (range 0-120 AU). Lower values represent reduced skin hydration in the upper skin layer. The measurement is based on capacitance measurement of a dielectric medium. The change in the dielectric constant due to skin surface hydration by capacitance differences of a precision capacitor is measured.

    Change from baseline after 3.5 hours loading period at visit 1 (Day 0), visit 2 (not before 3 weeks after visit 1), visit 3 (not before 3 weeks after visit 2), visit 4 (not before 3 weeks after visit 3).

  • Change in Erythema Index (EI) From Baseline

    Mexameter MX18 (Courage and Khazaka Electronic GmbH) was used to measure the Erythema index at the sacrum. This device uses specific wavelengths (the intensity of the reflected red (λ = 660 nm) and green (λ = 568 nm) lights) to measure the absorption capacity of the skin (specifically the content of hemoglobin in the skin) and presents values from 0 to 999. Lower values represent less redness.

    Change from baseline after 3.5 hours loading period at visit 1 (Day 0), visit 2 (not before 3 weeks after visit 1), visit 3 (not before 3 weeks after visit 2), visit 4 (not before 3 weeks after visit 3).

  • Change in Average Roughness (Rz) From Baseline

    The Visioscan VC 98 camera (Courage and Khazaka Electronic GmbH) was used to capture images of the sacrum. The special LED UV light source with diffuser provides sharp, very high resolution images of the skin surface (255 grey levels representing different depths). The grey level distribution allows the calculation of different roughness parameters to quantitatively describe the skin surface.

    Change from baseline after 3.5 hours loading period at visit 1 (Day 0), visit 2 (not before 3 weeks after visit 1), visit 3 (not before 3 weeks after visit 2), visit 4 (not before 3 weeks after visit 3).

  • Change in Arithmetic Average Roughness (Ra) From Baseline

    The Visioscan VC 98 camera (Courage and Khazaka Electronic GmbH) was used to capture images of the sacrum. The special LED UV light source with diffuser provides sharp, very high resolution images of the skin surface (255 grey levels representing different depths). The grey level distribution allows the calculation of different roughness parameters to quantitatively describe the skin surface.

    Change from baseline after 3.5 hours loading period at visit 1 (Day 0), visit 2 (not before 3 weeks after visit 1), visit 3 (not before 3 weeks after visit 2), visit 4 (not before 3 weeks after visit 3).

  • Change in Maximum Roughness (Rmax) From Baseline

    The Visioscan VC 98 camera (Courage and Khazaka Electronic GmbH) was used to capture images of the sacrum. The special LED UV light source with diffuser provides sharp, very high resolution images of the skin surface (255 grey levels representing different depths). The grey level distribution allows the calculation of different roughness parameters to quantitatively describe the skin surface.

    Change from baseline after 3.5 hours loading period at visit 1 (Day 0), visit 2 (not before 3 weeks after visit 1), visit 3 (not before 3 weeks after visit 2), visit 4 (not before 3 weeks after visit 3).

  • Change in Interleukin IL-1alpha Concentration From Baseline

    Based on Cyanoacrylate Skin Surface (CSSS)-Stripping, corneocytes was collected in order to analyse changes regarding interleukin IL-1alpha concentrations.

    Change from baseline after 3.5 hours loading period at visit 1 (Day 0), visit 2 (not before 3 weeks after visit 1), visit 3 (not before 3 weeks after visit 2), visit 4 (not before 3 weeks after visit 3).

Secondary Outcomes (3)

  • Occurence of Sacral Pain

    Captured from baseline until the end of the loading period after 3.5 hours at visit 1 (Day 0), visit 2 (not before 3 weeks after visit 1), visit 3 (not before 3 weeks after visit 2), visit 4 (not before 3 weeks after visit 3).

  • Time Until First Reporting of Sacral Pain

    Sacral pain was assessed from baseline up until 3.5 hours loading period at visit 1 (Day 0), visit 2 (not before 3 weeks after visit 1), visit 3 (not before 3 weeks after visit 2), visit 4 (not before 3 weeks after visit 3).

  • Change in Erythema Score From Baseline

    Change from baseline after 3.5 hours loading period at visit 1 (Day 0), visit 2 (not before 3 weeks after visit 1), visit 3 (not before 3 weeks after visit 2), visit 4 (not before 3 weeks after visit 3).
