A blast injury is a complex type of physical trauma resulting from direct or indirect exposure to an explosion. [1] Blast injuries occur with the detonation of high-order explosives as well as the deflagration of low order explosives. These injuries are compounded when the explosion occurs in a confined space.

2023年7月17日 · Tertiary blast injuries are caused when the person in displaced through the air and impacts on another object by the blast wind, or when a structure collapses and causes injury to the person. The resulting injury can be either blunt trauma due to the impact or penetrating injury if the victim is propelled and the striking structure enters the body.

2024年12月11日 · A blast injury is physical trauma caused by the rapid pressure wave and associated fragments generated by an explosion. 1,2 The resulting blast wave compresses air within...

2024年10月18日 · EMS providers, as well as police officers and firefighters who are likely to assist in triage and moving patients to a casualty collection point, should have a basic understanding of the four types...

2024年9月23日 · A blast injury is a complex type of physical trauma resulting from direct or indirect exposure to an explosion. Blast injuries range from internal organ injuries, including lung and traumatic brain injury (TBI), to extremity injuries, burns, hearing, and vision injuries...

Blast injuries include both physical and psychological trauma. Physical trauma includes fractures, respiratory compromise, injuries to soft tissue and internal organs, internal and external blood loss with shock, burns, and sensory impairment, especially of hearing and sight.

Injuries produced by the blast may be primary due to the blast wave or secondary due to flying debris or shrapnel. Tertiary injuries are caused by the blast wind either directly or indirectly. In addition burns, crush injuries and stampeding amount to massive casualties. 1. …

2014年4月14日 · Explosive blast may have five distinct acute effects on the body (see Figure 3-2): The primary blast mechanism causes injuries as sole consequences of the shock wave–body interaction; the secondary blast mechanism is due to the propulsion of fragments of debris by the explosion and their connection with the body, which causes penetrating or blun...

2015年6月15日 · Primary injuries result from the effect of transmitted blast waves on gas-containing structures, secondary injuries result from the impact of airborne debris, tertiary injury results from transposition of the entire body due to blast wind or structural collapse, and quaternary injuries include almost everything else.

Blast injuries are characterized by interwoven mechanisms of systemic, local, and cerebral responses to blast exposure (Cernak, 2010). When a blast generated by explosion strikes a living body, part of the shock wave is reflected and another fraction is absorbed becoming a tissue-transmitted shock wave.
