Issue Date: | 2024 | Publisher: | WILEY | Source: | International Wound Journal, 21 (2) (Art N° e14674) | Abstract: | This article describes the contemporary bioengineering theory and practice of evaluating the fluid handling performance of foam-based dressings, with focus on the important and clinically relevant engineering structure-function relationships and on advanced laboratory testing methods for pre-clinical quantitative assessments of this common type of wound dressings. The effects of key wound dressing material-related and treatment-related physical factors on the absorbency and overall fluid handling of foam-based dressings are thoroughly and quantitively analysed. Discussions include exudate viscosity and temperature, action of mechanical forces and the dressing microstructure and associated interactions. Based on this comprehensive review, we propose a newly developed testing method, experimental metrics and clinical benchmarks that are clinically relevant and can set the standard for robust fluid handling performance evaluations. The purpose of this evaluative framework is to translate the physical characteristics and performance determinants of a foam dressing into achievable best clinical outcomes. These guiding principles are key to distinguishing desirable properties of a dressing that contribute to optimal performance in clinical settings. | Notes: | Gefen, A (corresponding author), Tel Aviv Univ, Fac Engn, Herbert J Berman Chair Vasc Bioengn, Dept Biomed Engn, IL-6997801 Tel Aviv, Israel. gefen@tauex.tau.ac.il |
