Superior absorption and retention properties of foam-film silver dressing versus other commercially available silver dressing

Abstract

BackgroundThe aim of this study is to investigate the physicochemical and structural properties of Medifoam®Silver and to compare with other commercially available silver-containing polyurethane (PU) foam dressing in vitro.MethodsSurface and cross-section of four polyurethane foam dressings were assessed with field-emission scanning electron microscope. Thickness, density, tensile strength, elongation, absorption rate, absorption/retention capacity and water-vapor transmission (WVT) were measured to compare physical properties of various dressing materials.ResultsAmong four tested dressings, Medifoam®Silver has relatively uniform and smallest pore size in both surface and cross-section. In comparison of absorption properties with other dressing materials, Medifoam®Silver has rapid absorption rate, good absorption/retention capacity and good WVT value.ConclusionsThe data further suggests that Medifoam®Silver is a promising candidate for wound healing management.

Driveline exit-site care protocols in patients with left ventricular assist devices: a systematic review

“…However, some researchers assumed the evidence for silver-based dressings in the prevention of infections to be insufficient and the costs too high [ 31 , 32 ]. Foam-based dressing is generally recommended for exudate wounds due to its absorbent property and is not recommended for use in dry wounds [ 28 , 33 ]. According to the results of our study and those reported in the literature, wound characteristics should be taken into consideration when choosing the covering material in driveline care protocol.…”

New promising antimicrobial material based on thermoplastic polyurethane modified with polymeric biocide polyhexamethylene guanidine hydrochloride

“…Silver ions can be released from the polymer matrix into the wound fluid or exudate and act against a wide spectrum of pathogens such as gram-negative and gram-positive bacteria, yeast and viruses. Because of this, silver-containing foam dressings have been commonly used for healing wounds, including burns, diabetic ulcers, and surgical wounds [21,22]. Silver-based biocides are nevertheless relatively expensive and in the case of nanoparticles it is necessary to implement complicated processes to disperse them homogeneously in the polymer matrix [19].…”
