Alginate dressings can be in the form of freeze-dried, porous (foam) sheets or flexible fibres. Flexible fibres are used to treat cavity wounds. The alginate will form a gel in contact with the exudates of the wound and give it a strong absorbent power. [2] There is no evidence of superior effectiveness in those with diabetic foot ulcers. [3]
A wound is any disruption of or damage to living tissue, such as skin, mucous membranes, or organs. [1] [2] Wounds can either be the sudden result of direct trauma (mechanical, thermal, chemical), or can develop slowly over time due to underlying disease processes such as diabetes mellitus, venous/arterial insufficiency, or immunologic disease.

The polyethylene glycol provides a moist environment allowing the iodine to reach the wound. [4] After a few days the dressing has a tendency to dry out, and must be changed often. Left on too long, it can engage with wound tissue and wound secretions when drier, and be more difficult to remove. [4]
Debride the wound – to remove slough and foreign objects from the wound to expedite healing; Reduce psychological stress – to obscure a healing wound from the view of the patient and others. Ultimately, the aim of a dressing is to promote healing of the wound by providing a sterile, breathable and moist environment that facilitates ...
Research into hormones and wound healing has shown estrogen to speed wound healing in elderly humans and in animals that have had their ovaries removed, possibly by preventing excess neutrophils from entering the wound and releasing elastase. [26] Thus the use of estrogen is a future possibility for treating chronic wounds.
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.

Wound assessment is a component of wound management.As far as may be practical, the assessment is to be accomplished before prescribing any treatment plan. The objective is to collect information about the patient and about the wound, that may be relevant to planning and implementing the treatment.
