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.
The type of wound (incision, laceration, puncture, etc.) has a major effect on the way a wound is managed, as does the area of the body affected and presence of any foreign objects in the wound. A serious wound or any complication may require a call to emergency medical services. Any wound requires being disinfected after it stops bleeding.
A penetrating head injury, or open head injury, is a head injury in which the dura mater, the outer layer of the meninges, is breached. [1] Penetrating injury can be caused by high- velocity projectiles or objects of lower velocity such as knives, or bone fragments from a skull fracture that are driven into the brain.
Chest injuries can be classified as blunt or penetrating. Blunt and penetrating injuries have different pathophysiologies and clinical courses. Specific types of injuries include: Injuries to the chest wall. Chest wall contusions or hematomas; Rib fractures; Flail chest; Sternal fractures; Fractures of the shoulder girdle
The primary indication for a resuscitative thoracotomy is a patient with penetrating chest trauma who has entered or is about to enter cardiac arrest. [4] Other indications for the use of this procedure include the appearance of blood from a chest tube that returns more than 1500 mL of blood during the first hour of placement, or ≥200 mL of ...
The first one is the use of tools that have been changed so that they are less likely to lead to a sharps injury such as blunt or taper-point surgery needles and safety engineered scalpels. [7] Needleless connectors (NCs) were introduced in the 1990s to reduce the risk of health care worker needlestick injuries. [ 15 ]
Penetrating injuries result in a single, full-thickness entry wound. In contrast, perforating injuries produce two full-thickness wounds at the entry and exit sites of the projectile. [3] A penetrating globe injury with a retained foreign object, called an intraocular foreign body, has a different prognosis than a simple penetrating trauma.
There are many causes of major trauma, blunt and penetrating, including falls, motor vehicle collisions, stabbing wounds, and gunshot wounds. Depending on the severity of injury, quickness of management, and transportation to an appropriate medical facility (called a trauma center) may be necessary to prevent loss of life or limb. The initial ...
