Too often, dressings are hastily removed and discarded without careful observation. High-speed bullets create shock waves that affect surrounding tissue and organs, causing blunt force trauma as a result. The delay can be affected by the virulence of the bacteria, the amount of contamination leading to infection, the degree of hose resistance and the nature of the wound.
