Hydrogel dressing is a medical dressing based on hydrogels, three-dimensional hydrophilic structure. [1] The insoluble hydrophilic structures absorb polar wound exudates and allow oxygen diffusion at the wound bed to accelerate healing. [2]
The gel may be designed to drain, or to remain within the structure of the adhesive matrix. [4] The moist conditions produced under the dressing are intended to promote fibrinolysis, angiogenesis and wound healing, without causing softening and breaking down of tissue. The gel which is formed as a result of the absorption of wound exudate is ...
A few examples of hydrogel use include organ regeneration, [2] wound healing, [3] [4] [5] and drug delivery. [6] [7] Hydrogels are generally classified based on the following characteristics: material, crosslinking mechanism, physical structure, electric charge, and response to stimuli. [8]
It contains gel forming agents such as carboxymethylcellulose, gelatin and pectin. When the dressing is in contact with the wound, the wound discharge are retained to form gel which provides moist environment for wound healing. It protects the wound from bacterial contamination, absorbs wound discharge, and digests necrotic tissues.
Unlike its previously approved product for small nicks and cuts, the new gel, Traumagel, can be used for life-threatening injuries, CEO and co-founder Joe Landolina told Reuters.
Self-healing hydrogels are a specialized type of polymer hydrogel. A hydrogel is a macromolecular polymer gel constructed of a network of crosslinked polymer chains. Hydrogels are synthesized from hydrophilic monomers by either chain or step growth, along with a functional crosslinker to promote network formation.
Hydrogels can be used as drug delivery vehicles, for transdermal application, ophthalmic drug delivery, [11] cancer treatment [12] or for wound dressing. [ 7 ] [ 13 ] As a type of water based formulation, hydrogels are generally less greasy and are easier to be removed than oil-based formulations like organogels. [ 6 ]
