Total body disruption

Last updated

Total body disruption is the acute, fatal destruction of the body. [1] Synonymous terminology from the field of emergency medical services (EMS) is gross dismemberment. [2]

Commonly referred to as being "blown up", "blown apart", " gibbed ", or "dashed to pieces" in older literature, [3] total body disruption may be caused by such traumas as being within or in close proximity to a powerful explosion, uncontrolled decompression, or implosion. It is the most severe type of blast injury. [4] Gross dismemberment may also be caused by a fall at terminal velocity onto a solid surface or water, from being within a high-speed crashing object, or during incidents involving high pressure differentials, where the body may be forced through a small crevice, as in the Byford Dolphin diving bell accident.

Total body disruption is invariably fatal to most complex life, such as humans, as structures necessary for continued survival are rendered non-functional. In the case of humans, the brain (if not destroyed) is deprived of oxygenated blood, while other organs (if not destroyed) are deprived of the involuntary functions. [5] In some jurisdictions, gross dismemberment is the only (and thence obligatory) assessment where EMS personnel may declare death. [6] [7]

Incomplete, initially unidentifiable human remains caused by total body disruption may be referred to as "disassociated portions". [8]

<span class="mw-page-title-main">Emergency tourniquet</span>

Emergency tourniquets are cuff-like devices designed to stop severe traumatic bleeding before or during transport to a care facility. They are wrapped around the limb, proximal to the site of trauma, and tightened until all blood vessels underneath are occluded. The design and construction of emergency tourniquets allows quick application by first aid responders or the injured persons themselves. Correct use of tourniquet devices has been shown to save lives under austere conditions with comparatively low risk of injury. In field trials, prompt application of emergency tourniquets before the patient goes into shock are associated with higher survival rates than any other scenario where tourniquets were used later or not at all.
