Anesthetizing materials based on polyvinyl alcohol fibre

Modern wound dressings: Manufacturing and properties

“…In order to attach drugs (antibiotics, antiseptics, anesthetics) to PVA fibers, these were modified through etherification with maleic acid and grafting of acrylic acid [21]. Such fibers were used to make unwoven and knitted tampons and ribbons.…”

“…The long time required for the production of antimicrobial dressings, which includes the process of chemical modification of the polymer matrix and the subsequent attachment of drugs, frequently makes this technology ineffective [16,18,20,21]. In this respect, an interesting alternative approach is offered by the introduction of biologically active substances into soluble polymer compositions, followed by the formation of wound dressings of the desired shape.…”
