A gunshot wound ( GSW) is a penetrating injury caused by a projectile (e.g. a bullet) from a gun (typically firearm or air gun ). [11] [12] Damages may include bleeding, bone fractures, organ damage, wound infection, loss of the ability to move part of the body and, in more severe cases, death. [2]

A gunshot is a single discharge of a gun, typically a man-portable firearm, producing a visible flash, a powerful and loud shockwave and often chemical gunshot residue. The term can also refer to a ballistic wound caused by such a discharge. Multiple discharges of one or more firearms are referred to as gunfire.

A transmediastinal gunshot wound is a penetrating injury to a person's thorax in which a bullet enters the mediastinum, possibly damaging some of the major structures in this area. Hemodynamic instability has been reported in approximately fifty percent of cases with a mortality rate ranging from twenty to forty percent. Some studies have shown mar...
Complications caused by a TMGSW can range from mild to life-threatening depending on which structures are damaged. It can be rapidly lethal if a major structure is involved. Some of the possible complications caused by a TMGSW are: 1. damage to great vessels such as the vena cava
Previously every stable patient that suffered a TMGSW received extensive evaluation that included chest radiography, oesophagography, esophagoscopy, angiography, bronchoscopy, cardiac ultrasound. Grossman et al. found evidence that the trajectory of the bullet can be delineated w
The criteria to define a patient as stable or unstable could have variations from institution to institution. For example, Burack et al. used a list of 6 criteria in his paper that defined an unstable hemodynamic state: Traumatic cardiac arrest or near arrest and an EDT[clarifica
Stable patients will be evaluated with CT, ultrasound, chest x ray as the institution's protocol specifies. When this initial survey is negative, patient can be observed with conservative management. In many cases, chest tubes are required due to concomitant lesions in the pleura
Unstable patients are managed by operative exploration of the mediastinum. Moribund patients will go through an emergency department thoracotomy. This measure is taken because at their arrival in the emergency room, these patients are in such critical condition that they would no

It produces a mechanical sound effect and a chemical gunshot residue. The term can also refer to a gunshot wound caused by the bullet. Multiple discharges of a firearm or firearms are referred to as gunfire. The word can mean either the sound of a gun firing, the projectiles that were fired, or both.
Ballistic trauma Ballistic trauma or gunshot wound (GSW) is a form of physical trauma sustained from the discharge of arms or munitions. [1] The most common forms of ballistic trauma stem from firearms used in armed conflicts, civilian sporting, recreational pursuits and criminal activity. [2]
The gunshot wound to the back of the president's head was described by the Bethesda autopsy as a laceration measuring 15 by 6 millimetres (0.59 in × 0.24 in), situated to the right and slightly above the external occipital protuberance.

Damages may include bleeding, bone fractures, organ damage, wound infection, loss of the ability to move part of the body and, in more severe cases, death. Damage depends on the part of the body hit, the path the bullet follows through the body, and the type and speed of ... Wikipedia
