To avoid all these drawbacks new wound dressing materials have been tested. So, PEO/PVA hydrogel, crosslinked by electron beams, has been synthesized and tested as dressing on animals wounds. Wounds dressed with a hydrogel healed almost completely within 14 days, while those using gauze were only half-healed within that time. Clinical tests confirmed the safety and effects of this product [234],...

The first authoritative monographs related to wound dressing materials appeared in early London and Edinburgh hospital dispensatories and later in the British Pharmaceutical Codices. The development of wound management products can be traced by examining these Codices together with the British Pharmacopoeia. The information is reflected in similar publications in the United States Pharmacopoeia and other national standards.

A brief review is presented of the chemical stmctures of alginate and chitosan and their performances of novel biomaterials were compared. Their uses in wound-dressing materials are outlined and binding with metal ions and antimicrobial properties are mentioned. 13 refs. 

Wound-dressing materials are mainly classified as absorbent and non-absorbent, depending on the types of fibres used. Dressings vary with the type of wound and wound management and no single dressing is universally applicable. An ideal dressing is normally expected to ...

Bacterial Cellulose has been shown to be a highly effective wound dressing material. In fact, the results of burns, diabetic ulcer, healing process can be show in Figs. 10.5 and 10.6a,b. The biomedical applications of BC include meniscus replacements (pig meniscus on the left, BC meniscus on the right), artificial blood vessels and wound dressing for skin healing [12, 20, 21] (Fig. 10.7).

Wound-dressing materials and tissue engineering are important domains under development [194-200]. New adhesives were proposed recently [201,202], Especially Az-chitosan was shown to be nontoxic, cytocompatible and mechanically suitable in peripheral surgeries [202], Chitosan is suitable for transmucosomal administration of drugs [203],...
