  2. FP-50002 EWMA/GNEAUPP 2014 Background Existence of several neonatal supportsurfaces however… Lack of evaluation regarding… • Interface pressure & pressureredistribution • Efficacy in thepreventionortreatment of PU

  3. FP-50002 EWMA/GNEAUPP 2014 Aim 5 2 1 • To assess the interface pressure and pressure redistribution of five devices of constant low pressure (static and mixed support surfaces). 3 4

  4. FP-50002 EWMA/GNEAUPP 2014 Methods Study design • Laboratory study with repeated measures design. Sample • Eight neonatal simulation dummies with different characteristics regarding head circumference, weight and height.

  5. FP-50002 EWMA/GNEAUPP 2014 Methods Supportdevices

  6. FP-50002 EWMA/GNEAUPP 2014 Methods Variables • Mean pressure (mmHg). • Maximum pressure (mmHg). • Mean pressure in head region (mmHg). • Area of contact (cm2). Equipment • XSENSOR X3 PX100:40.40.002 device. Procedure • See: E-poster no. 50006.

  7. FP-50002 EWMA/GNEAUPP 2014 Methods Statistical analysis • Descriptive statistics. • Due to a small sample size, a non-parametric test (Friedman test) was carried out to assess differences among groups. If a significant difference was found, post hoc comparisons among groups were performed using the Wilcoxon-Nemenyi-McDonald-Thompson test. • The analysis was carried out by means of the R environment (The R Foundation for Statistical Computing). • Data set and code employed for the analysis can be found at www.figshare.com (*). *http://dx.doi.org/10.6084/m9.figshare.977866

  8. FP-50002 EWMA/GNEAUPP 2014 Results Lowest values! Highest values!

  10. FP-50002 EWMA/GNEAUPP 2014 Results Post hoc analysis: mean pressure (p-value)

  11. Results

  12. FP-50002 EWMA/GNEAUPP 2014 Results Post hoc analysis: maximum pressure (p-value)

  13. Results

  14. FP-50002 EWMA/GNEAUPP 2014 Results Post hoc analysis: pressure area (p-value)

  15. Results

  16. Conclusion • The “T” device presents the best values of pressure relief. • The polyester fiber device presents the best values of pressure redistribution. • Adding an upper layer of polyester fiber to the “T” device could result in a better support surface. • Next step: studying the properties of the new support surface in healthy subjects under clinical conditions.
