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.
Negative pressure wound therapy device. Negative-pressure wound therapy (NPWT), also known as a vacuum assisted closure (VAC), is a therapeutic technique using a suction pump, tubing, and a dressing to remove excess wound exudate and to promote healing in acute or chronic wounds and second- and third-degree burns.
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.

Balanced anesthesia can also minimize the pain patients suffer. Pain may delay wound healing, decrease appetite, and even result in death. [17] Using the proper amount of analgesics can reduce the amount of inhalant anesthetics required and help patients reduce the pain. [18]
After surgery, drains can be placed to remove blood, lymph, or other fluids that accumulate in the wound bed. This helps to promote wound healing and allows healthcare providers to monitor the wound for any signs of internal infection or damage to surgically repaired structures.
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.
the nature of the wound, whether it is a laceration, abrasion, bruise or burn; the size of the wound in length, width and depth; the extent of the overall area of tissue damage caused by the impact of a mechanical force, or the reaction to chemical agents in, for example, fires or exposure to caustic substances.
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 ...
