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]
Similarly, there is wide variation in prevalence: 10% to 18% in acute care, 2.3% to 28% in long-term care, and 0% to 29% in home care. There is a much higher rate of bedsores in intensive care units because of immunocompromised individuals, with 8% to 40% of those in the ICU developing bedsores. [ 97 ]
The Lund and Browder chart is a tool useful in the management of burns for estimating the total body surface area affected. It was created by Dr. Charles Lund, Senior Surgeon at Boston City Hospital, and Dr. Newton Browder, based on their experiences in treating over 300 burn victims injured at the Cocoanut Grove fire in Boston in 1942.
Two packages of gauze. One 10 cm by 4.1 m. The other 5 by 5 cm. Three types of gauze Depiction of a dressing on a face from a painting from 1490. Modern dressings [3] include dry or impregnated gauze, plastic films, gels, foams, hydrocolloids, hydrogels, and alginates.
Timing is important to wound healing. Critically, the timing of wound re-epithelialization can decide the outcome of the healing. [11] If the epithelization of tissue over a denuded area is slow, a scar will form over many weeks, or months; [12] [13] If the epithelization of a wounded area is fast, the healing will result in regeneration.
In a major injury, if epithelial cell migration and tissue contraction cannot cover the wound, suturing the edges of the injured skin together, or even replacement of lost skin with skin grafts, may be required to restore the skin. As epithelial cells continue to migrate around the scab, the dermis is repaired by the activity of stem cells.

Wound bed, wound edge and periwound skin should be examined before the initial treatment plan is devised. It should also be re-assessed at each visit or each dressing change. For wound bed, the following parameters are assessed: Tissue type; presence and percentage of non-viable tissue covering the wound bed; Level of exudate; Presence of infection
