Non-fatal gunshot wounds frequently have mild to severe long-lasting effects, typically some form of major disfigurement such as amputation because of a severe bone fracture and may cause permanent disability. A sudden blood gush may take effect immediately from a gunshot wound if a bullet directly damages larger blood vessels, especially arteries. Pathophysiology
The degree of tissue disruption caused by a projectile is related to the cavitation the projectile creates as it passes through tissue. A bullet with sufficient energy will have a cavitation effect in addition to the penetrating track injury. As the bullet passes through the tissue, initially crushing then lacerating, the space left forms a cavity; this is called the permanent cavity. Higher-velocity bullets create a pressure wave that forces the tissues away, creating not only a permanent cavity the size of the caliber of the bullet but a temporary cavity or secondary cavity, which is often many times larger than the bullet itself. The temporary cavity is the radial stretching of tissue around the bullets wound track, which momentarily leaves an empty space caused by high pressures surrounding the projectile that accelerate material away from its path. The extent of cavitation, in turn, is related to the following characteristics of the projectile:

Kinetic energy: KE = 1/2mv2 (where m is mass and v is velocity). This helps to explain why wounds produced by projectiles of higher mass and/or higher velocity produce greater tissue disruption than projectiles of lower mass and velocity. The velocity of the bullet is a more important determinant of tissue injury.
It has been famous in 1964, under the trade name Vanquish by Sterling Drug, which after a series of mergers and acquisitions became a unit of Bayer AG.In Germany, it is sold as dolomo, Dolopyrin AL, HA-Tabletten, Melabon K, Neuralgin, ratiopyrin, Thomapyrin Classic, Thomapyrin Intensiv, in Austria as Thomapyrin, and InfluASS, in Israel as Acamol Focus, Paramol Target and Exidol, in Romania as Antinevralgic P  and Antinevralgic Forte, and in Russia, Belarus and Eastern Europe as Citramon. == References ==
