Injuries due to shockwave produced by bomb blast

A bomb explosion produces a shockwave that is composed of a high pressure wave followed by a negative pressure wave. Pressure exceeding 700 kilopascals (100lb/sq inch) is necessary to produce serious injury to the body.

  • person can be thrown away due to the force of the blast, causing blunt force trauma
  • shockwave passing through the body mainly injures non homogenous tissues like lung, whereas homogenous tissues such as liver and muscle are spared

Blast lung: Injury to the lung produced as a result of  the shockwave passing through the body

  • subpleural patchy hemorrhages
  • rupture of alveolar septa
  • intrapulmonary hemorrhage
  • desquamation of alveolar and bronchial epithelium
  • pulmonary edema
  • bronchopneumonia

Other injuries

  • subperitoneal hemorrhages
  • lacerations of viscera
  • rupture of stomach, intestine
  • intracranial hemorrhage
  • brain contusion
  • injury to heart, aorta
  • pneumothorax
  • air embolism – can be cause of death
