Modern Wound Dressings: Hydrogel Dressings

Modern wound dressings (WDs) are aimed to solve these issues. At the same time, hydrogels, unlike other types of modern WDs (foam, films, hydrocolloids), have positive degradation properties that makes them the perfect choice in applications where a targeted delivery of bioactive substances to the wound is required. This mini review is focused on different types of traditional and modern WDs with an emphasis on hydrogels.

Current trends in the development of wound dressings, biomaterials and devices

There are many wound-care products available including simple protective layers, hydrogels, metal ion-impregnated dressings and artificial skin substitutes, which facilitate surface closure. This review examines recent developments in wound dressings, biomaterials and devices.

Synthetic hydrogels VI. Hydrogel composites as wound dressings and implant materials

An overview is presented of the use of hydrogel composites as biomaterials. These range from laminates or coatings (in which a homogeneous hydrogel is used in conjunction with a more mechanically stable substrate), through blends of hydrogels with synthetic hydrophobic polymers, to the use of two-component systems in which water enhances the compatibility of two structurally different polymers. Although synthetic hydrogels provide an ideal basis for materials of these types, naturally occurring hydrophilic polymers with their unique properties have a major contribution to make. https://www.sciencedirect.com/science/article/abs/pii/0142961289900021

>Can't I just have a Band-Aid?

Some wounds are brutal and are the results of horrific physical trauma or burns. Some cultures still burn women's faces with acid, for example, or practice bride-burning. Trauma caused by modern explosives encased in steel shells or steel vehicles, fuels, chemicals, blister agents, propellants … If you know what 'debride' means you likely understand why a bandage sometimes isn't enough. Hydrogels, for example, are like gelatins that retain water. They reduce moisture loss.

>United States Capitol.

"Drawing shows the ruins of the U.S. Capitol following British attempts to burn the building; includes fire damage to the Senate and House wings, damaged colonnade in the House of Representatives shored up with firewood to prevent its collapse, and the shell of the rotunda with the facade and roof missing." "1 drawing on paper : ink and watercolor" "Historical context: George Munger's drawing, one of the most significant and compelling images of the early republic, reminds us how short-lived the history of the United States might have been. In the evening hours of August 24, 1814, during the second year of the War of 1812, British expeditionary forces under the command of Vice Admiral Sir Alexander Cockburn and Major General Robert Ross set fire to the unfinished Capitol Building in Washington, D.C. All the public buildings in the developing city, except the Patent Office Building, were put to the torch in retaliation for what the British perceived as excessive destruction by American forces the year before in York, capital of upper Canada. At the time of the British invasion, the unfinished Capitol building comprised two wings connected by a wooden causeway. This exceptional drawing, having descended in the Munger family, was purchased by the Library of Congress at the same time the White House purchased the companion view of 'The President's House.'"
