Foam dressings

Abstract

A guide to the properties and uses of the main foam dressings available in the UK.

Spray Film-Forming systems as promising topical in situ Systems: A review

“…To solve problems of sorption of a large volume of exudate, mechanical protection and cushioning (for example, in the treatment of bedsores) it is advisable to use dressings dense and plastic (medium and high density). After dosing using a spray system, highly adsorptive sponge coatings, aerogels and solid foams can be formed on the wound surface ( Thomas, 1993 , Brumberg et al, 2021 ).…”

“…In some works ( Park et al, 2018 , Dai et al, 2015 , Chen et al, 2020 ), the use of terminology characteristic of dressings (“bandage”, “dressing”) is conditioned by the need to emphasize in this way the structural features of the form formed in situ . Often such systems have the final appearance of a dense, durable, rigid coating that is applied to the wound surface for a long time (up to 7 days) ( Thomas, 1993 , Bastos et al, 2020 ). However, quite often the term “liquid bandage”, for example, does not carry such a semantic load.…”

Novel Dressing Method of Fixing Polyurethane Foam on the Soft Tissue Defect of the Finger

“…Dressing foam manuals are advised to change it in accordance with the amount of exudate and the degree of dirt on the wound [13]. Therefore, after fixing the foam, the patient was carefully examined during the dressing of the peripheral area of foam fixation dressing to see whether inflammation or infection occurred.…”

Mechanical and contact characteristics of foam materials within wound dressings: Theoretical and practical considerations in treatment

“…2,5 The purpose of this article is to review the contemporary knowledge and formulate the bioengineering theory that applies to porous materials in wound dressings, and primarily, to foams that are in extensive use in contemporary dressings. 17 Foams in foam-based dressings are most commonly made of soft polyurethane, which is often treated in various ways to create a hydrophilic non-adherent membrane that allows the passage of exudate through to the insulating foam body of the dressing. Foams have many important advantages as a wound dressing material over traditional textile dressings (eg, cotton bleached gauze) or hydrocolloid dressings, in light of their superior fluid absorbency and lower risk to adhere to fragile wound bed tissues.…”

“…Understanding material behaviours and how to quantitatively describe the material microarchitecture is therefore vital to achieve desirable clinical performance through appropriate design, processing and manufacturing of wound dressings 2,5 .
