Title: | The frictional energy absorber effectiveness and its impact on the pressure ulcer prevention performance of multilayer dressings | Authors: | Marche, Cecile Creehan, Sue GEFEN, Amit |
Issue Date: | 2024 | Publisher: | WILEY | Source: | International Wound Journal, 21 (4) (Art N° e14871) | Abstract: | Pressure ulcers including heel ulcers remain a global healthcare concern. This study comprehensively evaluates the biomechanical effectiveness of the market-popular ALLEVYN (R) LIFE multilayer dressing in preventing heel ulcers. It focuses on the contribution of the frictional sliding occurring between the non-bonded, fully independent layers of this dressing type when the dressing is protecting the body from friction and shear. The layer-on-layer sliding phenomenon, which this dressing design enables, named here the frictional energy absorber effectiveness (FEAE), absorbs approximately 30%-45% of the mechanical energy resulting from the foot weight, friction and shear acting to distort soft tissues in a supine position, thereby reducing the risk of heel ulcers. Introducing the novel theoretical FEAE formulation, new laboratory methods to quantify the FEAE and a review of relevant clinical studies, this research underlines the importance of the FEAE in protecting the heels of at-risk patients. The work builds on a decade of research published by our group in analysing and evaluating dressing designs for pressure ulcer prevention and will be useful for clinicians, manufacturers, regulators and reimbursing bodies in assessing the effectiveness of dressings indicated or considered for prophylactic use. | Notes: | Gefen, A (corresponding author), Tel Aviv Univ, Fac Engn, Dept Biomed Engn, IL-69978 Tel Aviv, Israel. gefen@tauex.tau.ac.il |
