Points & Pearls Excerpt

  • Explosive events can result from terrorist bombings, industrial and construction accidents, planned avalanches, and fireworks. The increase in injuries and fatalities is primarily due to homemade/recreational explosives.2
  • Low-order explosives include gunpowder, pipe bombs, Molotov cocktails, and smokeless and black powder. These more often produce fragmentation injuries and thermal burns.
  • High-order explosives include TNT, ammonium nitrate, fuel oil, dynamite, and nitroglycerine. These typically produce higher temperatures over a shorter period of time, and produce a overpressure blast wave.
  • Exposure to peak overpressure in a confined space (eg, a vehicle or underwater) produces greater injury.
  • Primary blast injury in closed spaces has a high likelihood for tympanic membrane rupture; however, it has a low sensitivity and specificity as a biomarker in blast injuries as a whole.49
