Editing Bleeding (section)

=== Traumatic injury ===
Traumatic bleeding is caused by some type of injury. There are different types of [[wound]]s which may cause traumatic bleeding. These include:
* [[Abrasion (medical)|Abrasion]] — Also called a graze, this is caused by transverse action of a foreign object against the skin, and usually does not penetrate below the [[Epidermis (skin)|epidermis]].
* [[Excoriation]] — In common with abrasion, this is caused by mechanical destruction of the skin, although it usually has an underlying medical cause.
* [[Hematoma]] — Caused by damage to a blood vessel that in turn causes blood to collect in an enclosed area.
* [[Laceration]] — Irregular wound caused by blunt impact to soft tissue overlying hard tissue or tearing such as in childbirth. In some instances, this can also be used to describe an incision.
* [[Surgical incision|Incision]] — A cut into a body tissue or organ, such as by a [[scalpel]], made during surgery.
* [[Penetrating trauma|Puncture Wound]] — Caused by an object that penetrated the skin and underlying layers, such as a nail, needle, or knife.
* [[Bruise|Contusion]] — Also known as a bruise, this is caused by a blunt trauma damaging tissue under the surface of the skin.
* [[Crush injury|Crushing]] Injuries — Caused by a great or extreme amount of force applied over a period of time. The extent of a crushing injury may not immediately present itself.
* [[Ballistic trauma|Ballistic Trauma]] — Caused by a projectile weapon such as a firearm. This may include two external wounds (entry and exit) and a contiguous wound between the two.

The pattern of injury, evaluation, and treatment will vary with the mechanism of the injury. Blunt trauma causes injury via a shock effect; delivering energy over an area. Wounds are often not straight and unbroken skin may hide significant injury. Penetrating trauma follows the course of the injurious device. As the energy is applied in a more focused fashion, it requires less energy to cause significant injury. Any body organ, including bone and brain, can be injured and bleed. Bleeding may not be readily apparent; internal organs such as the liver, kidney, and spleen may bleed into the abdominal cavity. The only apparent signs may come with blood loss. Bleeding from a bodily orifice, such as the rectum, nose, or ears may signal internal bleeding, but cannot be relied upon. Bleeding from a [[medical procedure]] also falls into this category.{{citation needed|date=June 2022}}
