Low-cost negative pressure wound therapy for gunshot traumatism in developing countries.

Wounds from gunshots and other explosive devices are a source of loss of substances directly or secondary to a well- conducted debridement. In addition, these types of wounds are by definition contaminated. The major challenge in this context for any surgeon remains coverage. The use of flap-type plastic surgery is one of the options if feasible. Another option is the use of vacuum dressing. VAC therapy gives better results than sugar and honey. In a humid environment, it ensures the drainage of exudates. It causes an increase in local blood flow by stimulating neoangiogenesis, it stimulates cell proliferation and also the granulation tissue. It leads to a decrease in bacterial colonization and tissue oedema. Four observations are presented to illustrate the feasibility of this treatment in developing country and to show its beneficial effects.
