[Blast injuries part 2 : Principles of medical treatment].

Abstract

Explosions can cause severe injuries, which affect multiple organ systems and leave extensive soft tissue defects. In unstable patients, damage control surgery initially focuses exclusively on controlling bleeding and contamination with the aim of preserving life and limbs. The excision of all necrotic tissue, extensive wound irrigation with antiseptic solutions and a calculated antibiotic prophylaxis, which is subsequently adapted to the microbiological findings, are the basis for sufficient infection control. As the tissue damage caused by the pressure surge can regenerate over time as well as become secondarily necrotic (developing wounds), several revision operations are often necessary to assess the viability of tissue in the sense of serial debridement. In the case of extensive soft tissue injuries temporary vacuum-assisted closure (VAC) techniques can bridge the time to the earliest possible definitive plastic surgical wound closure; however, this must not delay the closure of the defect.
