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.
The optimal timing of performing wound debridement and closure is debated and dependent on the severity of the injury, resources and antibiotics available, and individual needs. [20] [1] Debridement time can vary from 6 to 72 hours, and closure time can be immediate (less than 72 hours) or delayed (72 hours to up to 3 months). [20]
Unlike hyperbaric oxygen treatment for chronic wounds, oxygen treatment used in this therapy is not systemic in nature and treats only the wound area. This treatment differs from topical oxygen treatments, as topical oxygen typically involves sporadic treatments of 1–3 hours several times per week, while TCOT treatment is 24/7 by nature.
The end goal of wound management is closure of the wound which can be achieved by primary closure, delayed primary closure, or healing by secondary intention, each of which is discussed below. Pain control is a mainstay of wound management, as wound evaluation, wound cleansing, and dressing changes can be a painful process. [27]
Skin graft with vacuum-assisted wound closure after 5 days. STSGs are suitable for large wounds and relatively avascular sites where FTSGs would have a high risk of failure. Only a portion of the skin, namely the epidermis and part of the dermis, is removed from the donor site using a powered dermatome. [17]
The polyhexanide treated wounds led to complete wound closure after 22.9 days, in comparison to the placebo octenidine treated wounds respectively, 24.1 days (p < 0.05) and 28.3 days (no statistical difference to placebo).
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.
Postoperative wounds are those wounds acquired during surgical procedures. Postoperative wound healing occurs after surgery and normally follows distinct bodily reactions: the inflammatory response, the proliferation of cells and tissues that initiate healing, and the final remodeling.
