Gunshot wound

A gun can shoot a small object. This object can hurt a person. It can cause a lot of bleeding.

This can break bones or hurt organs inside. The damage depends on how fast the object moves. It also depends on where it hits the body.

Sometimes these hurts are very serious. A person might not be able to move. They might even die.

Doctors work hard to help. They first make sure the area is safe. Then they try to stop the bleeding.

They also check how the person breathes. They want to help the person stay alive.

A gunshot wound happens when a bullet hits a body.

The damage depends on many things. It depends on the type of gun used. It also depends on how fast the bullet moves. A fast bullet has more kinetic energy. Kinetic energy is the power a moving object has. High speed can cause more damage to parts of the body.

When a bullet enters, it makes a hole. This is called a permanent cavity. Fast bullets also create a temporary cavity. This is a large, empty space made by pressure. This pressure stretches the tissues around the path.

These wounds can cause serious problems. They can cause heavy bleeding. This can lead to hypovolemic shock. This is when the body does not get enough oxygen. This happens because blood carries oxygen. A bullet can also hit vital organs. It can hit the heart, lungs, or brain.

Doctors use special steps to help. They first make sure the area is safe. They work to stop bleeding. They also check how the person breathes.

A gunshot wound happens when a projectile, like a bullet, enters a body. These injuries can be very serious and cause many different types of damage. A person might experience heavy bleeding or broken bones from the impact. The bullet can also damage organs or cause an infection in the wound. Sometimes, the injury makes it hard for a person to move their body. The amount of damage depends on which part of the body is hit. It also depends on the speed and the type of bullet used.

When a bullet moves through tissue, it creates two different types of spaces. The first is called a permanent cavity. This is the actual hole or track left behind by the bullet. High-speed bullets also create something called a temporary cavity. This is a large, empty space caused by a sudden pressure wave. This wave pushes the surrounding tissue away from the bullet's path. This stretching happens very quickly and can be much larger than the bullet itself. The amount of energy transferred depends on the mass and the speed of the bullet.

Scientists and doctors study how bullets behave to understand these injuries. They look at kinetic energy, which is the energy an object has because it is moving. The speed of a bullet is a very important part of this energy. If you double the speed of a bullet, its energy actually increases four times. This is why fast bullets from rifles cause more tissue disruption than slower handgun bullets. Some bullets, like those used by the US military, are very fast even if they are light. This high speed helps them carry a lot of energy into the target.

There are different ways to group these wounds based on how fast the bullet travels. Low-velocity wounds come from small handguns and usually cause less damage. Medium-velocity wounds can come from shotguns or larger handguns. High-velocity wounds are caused by powerful rifles and often cause very large areas of injury. In 2016, there were about 251,000 firearm deaths around the world. Of those deaths, 161,000 were from assaults and 67,500 were from suicides. In the United States alone, guns caused about 40,000 deaths in 2017.

Understanding these injuries helps doctors and leaders keep people safer. When a person is hurt, medical teams follow a set of rules called the ATLS protocol. They first make sure the area is safe for them to work. Then they work to stop major bleeding and check how the person breathes. They also check the person's circulation and their brain function. Many groups suggest using background checks and safe storage to prevent accidents. Keeping guns locked and unloaded can help protect everyone in a home.

A gunshot wound (GSW) is a penetrating injury caused by a projectile, such as a bullet, being fired from a gun. These injuries are often more devastating than other types of penetrating wounds. This is because the path and fragmentation of a bullet can be unpredictable once it enters the body. Damage from a GSW can include bleeding, bone fractures, and organ damage. It can also cause wound infections or a loss of movement in certain body parts. In many severe cases, these injuries can be fatal.

The physical damage caused by a bullet is linked to how it moves through tissue. As a projectile passes through, it creates a permanent cavity. This is the actual hole or track left behind by the bullet. High-velocity bullets also create a temporary cavity, or secondary cavity. This is a radial stretching of tissue around the wound track. A pressure wave forces the tissue away from the bullet's path, creating an empty space. This temporary cavity is often many times larger than the bullet itself.

The amount of tissue disruption is related to the projectile's kinetic energy. Kinetic energy is the energy an object possesses due to its motion. It is calculated using the formula KE = 1/2mv², where 'm' is mass and 'v' is velocity. While both mass and velocity contribute to energy, velocity is a much more important determinant. If the mass of a bullet is doubled, the energy doubles. However, if the velocity is doubled, the energy increases four times. This explains why high-speed bullets cause significantly more damage.

Medical professionals classify these wounds by the speed of the projectile using the Gustilo open fracture classification. Low-velocity wounds travel at less than 335 meters per second (m/s). These are typical of small caliber handguns and usually cause less soft tissue damage. Medium-velocity wounds travel between 360 m/s and 600 m/s. These are often seen with shotgun blasts or large handguns. High-velocity wounds travel between 600 m/s and 1,000 m/s. These are usually caused by powerful rifles and carry a high risk of infection due to the large area of destroyed tissue.

Global statistics show the scale of firearm-related injuries. In 2016, firearms resulted in 251,000 deaths globally. This was an increase from 209,000 deaths in 1990. Of these 2016 deaths, 161,000, or 64%, resulted from assault. Another 67,500, or 27%, were suicides, and 23,000, or 9%, were accidents. In the United States, guns caused about 40,000 deaths in 2017. These deaths are most common in males between the ages of 20 and 24. The economic cost of gunshot wounds in the U.S. is estimated at $140 billion per year.

When treating a patient, medical teams use the Advanced Trauma Life Support (ATLS) protocol. Before management begins, the area must be verified as safe. The first step is to assess and protect the airway and the cervical spine. Next, teams maintain breathing and oxygenation. They then assess circulation and work to control bleeding. This helps maintain organ perfusion, which is the delivery of blood to organs. Finally, doctors perform a neurological exam and expose the entire body to search for missed injuries.

One specific and rare type of injury is the Kronlein shot. This is a distinctive headshot wound caused by high-velocity rifle bullets or shotgun slugs. It is believed to be caused by a hydrodynamic effect. The high velocity creates hydraulic pressure within the skull. This pressure can lead to the explosive ejection of the brain from the fractured skull. Preventing such injuries involves various interventions. These include criminal background checks, mental health care, and safer firearm storage. Keeping guns locked and unloaded is associated with a lower risk of injury for all household members.
