About this study
Official title: Comparing the Effects of Three Different Dressings on the Cutaneous Response to Pressure and Shear of Sacral Skin: an Exploratory Crossover Study
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.
Read the detailed description
Pressure ulcers (PUs) are severe and unwanted cutaneous lesions and subcutaneous wounds caused by prolonged skin and underlying soft tissue deformation. In the supine position they predominantly occur near to bony prominences, like at the sacral area. The cornerstone of PU prevention is repositioning, early mobilization and the use of special support surfaces. In addition, empirical evidence suggests that the application of preventive dressings on PU predilection sites helps to prevent PU development.
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. Recently it could be shown that there are associations between structural and functional skin changes at the sacral area during loading. 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 no dressing, ALLEVYN Life Sacrum and Optifoam® Gentle Liquitrap Sacrum.
The procedure of one visit will be as follows:
After a skin acclimatization time of 30 minutes baseline measurements and Cyanoacrylate Skin Surface (CSSS)-stripping will be performed. Then a randomization envelope will be opened and the corresponding dressing will be applied or the skin will be left uncovered. The subject will then lie in supine position on a standard hospital mattress for a loading period of 3.5 hours. Every 30 minutes the head of the bed will be elevated to 45° for five minutes. During these five minutes, the participants will be instructed to bend their knees and to drag the feet repeatedly forth and back 10 times in order to simulate shear forces. The whole exercise will be done six times, after 0.5, 1, 1.5, 2, 2.5 and 3 hours. After 3.5 hours loading time in supine position the subjects will move into prone position. The dressing (if present) will be removed and all skin measurements and CSSS-stripping will be conducted again. The subjects will come back for another three times completing the remaining interventions. At the end, each volunteer will have received all three types of dressings once and once no dressing. In between, there are at least 3 weeks to prevent possible carry over effects.

What is being measured
The primary outcome is the main question the study is designed to answer.
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
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 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.
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.
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 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.
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 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.
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 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.
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 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.
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).
Secondary outcomes (3)
Occurence of Sacral Pain
The occurrence of pain (yes/no)
Measured: 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
Time from baseline until the subject reported pain at sacrum
Measured: 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
Erythema was assessed by visual inspection. A metric scale will be used: 0 = none 1 = mild (slight reddening), 2 = moderate (distinct redness), 3 = severe (strong redness, dark red)
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).
