Commonly seen in military situations but also in terrorism incidents, industrial settings and some domestic incidents e.g. drug lab. Types of injury can be multifactorial.
The numbering system is academic but helps the clinician to consider the different patterns of injury that may occur:
- Type I – from pressure wave (injury to body cavities, aerated structures, and hollow organs)
- Type II – by shrapnel (penetrating injury)
- Type III – from person being propelled to ground or solid object (blunt injury) or impaled (penetrating injury)
- Type IV – other e.g. burns, radiation, chemicals
