Secondary blast wounds may be lethal and therefore many anti-personnel explosive devices are designed to generate fast-flying fragments. Most casualties are caused by secondary injuries as shrapnels generally affect a larger area than the primary blast area, because debris can easily be propelled for hundreds or even thousands of meters.
The term "shrapnel" is commonly, although incorrectly from a technical standpoint, used to refer to fragments produced by any explosive weapon. However, the shrapnel shell, named for Major General Henry Shrapnel of the British Royal Artillery, predates the modern high-explosive shell and operates by an entirely different process. [2]
Penetrating trauma is an open wound injury that occurs when an object pierces the skin and enters a tissue of the body, creating a deep but relatively narrow entry wound.In contrast, a blunt or non-penetrating trauma may have some deep damage, but the overlying skin is not necessarily broken and the wound is still closed to the outside environment.
Animation of a bursting shrapnel shell Setting a time fuse (left) and loading a shell into a gun. Shrapnel shells were anti-personnel artillery munitions that carried many individual bullets close to a target area and then ejected them to allow them to continue along the shell's trajectory and strike targets individually.
In modern typical usage, the solution is applied to the wound once daily for lightly to moderately exudative wounds, and twice daily for heavily exudative wounds or highly contaminated wounds. [ 3 ] The healthy skin surrounding the wound should preferably be protected with a moisture barrier ointment (e.g., petroleum jelly ) or skin sealant as ...
Abdominal CT showing left renal artery injury. Blunt abdominal trauma (BAT) represents 75% of all blunt trauma and is the most common example of this injury. [3] Seventy-five percent of BAT occurs in motor vehicle crashes, [4] in which rapid deceleration may propel the driver into the steering wheel, dashboard, or seatbelt, [5] causing contusions in less serious cases, or rupture of internal ...
Chronic wound healing may be compromised by coexisting underlying conditions, such as venous valve backflow, peripheral vascular disease, uncontrolled edema and diabetes mellitus. If wound pain is not assessed and documented it may be ignored and/or not addressed properly. It is important to remember that increased wound pain may be an ...
These mines are deemed to be more efficient than purely "blast effect" mines, because the shrapnel covers a greater area, potentially injuring more combatants. The shrapnel from these mines can even disable some armoured vehicles, by puncturing their tires and—in the case of soft-skinned vehicles—also penetrating the skin and damaging ...
