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 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.
Secondary blast wounds may be lethal and therefore many anti-personnel explosive devices are designed to generate fast-flying fragments. Most casualties are caused by secondary injuries as shrapnels generally affect a larger area than the primary blast area, because debris can easily be propelled for hundreds or even thousands of meters.
Some troops leave the battlefield injured. Others return from war with mental wounds. Yet many of the 2 million Iraq and Afghanistan veterans suffer from a condition the Defense Department refuses to acknowledge: Moral injury.
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.
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.
For Grade I and II fractures, wound can be healed by secondary intention or through primary closure. There is conflicting evident to suggest the effectiveness of Negative-pressure wound therapy (vacuum dressing), with several sources citing a decreased risk in infection, [ 25 ] [ 26 ] and others suggesting no proven benefit.
The FBI issued seeking information posters for two Iranian intelligence officers believed to be responsible for the 2007 abduction of Robert Levinson.
