Stab wounds can cause various internal and external injuries. They are generally caused by low-velocity weapons, meaning the injuries inflicted on a person are typically confined to the path it took internally, instead of causing damage to surrounding tissue, which is common of gunshot wounds.
Traumatic cardiac arrest ( TCA) is a condition in which the heart has ceased to beat due to blunt or penetrating trauma, such as a stab wound to the thoracic area. [1] It is a medical emergency which will always result in death without prompt advanced medical care. Even with prompt medical intervention, survival without neurological ...
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.
Subcutaneous emphysema can result from puncture of parts of the respiratory or gastrointestinal systems. Particularly in the chest and neck, air may become trapped as a result of penetrating trauma (e.g., gunshot wounds or stab wounds) or blunt trauma. Infection (e.g., gas gangrene) can cause gas to be trapped in the subcutaneous tissues.
Stab wounds to the heart are typically survivable with medical attention, though gunshot wounds to the heart are not. The right ventricle is most susceptible to injury due to its prominent location. The two primary consequences of traumatic injury to the heart are severe hemorrhaging and fluid buildup around the heart.
Specialty. Emergency medicine. A liver injury, also known as liver laceration, is some form of trauma sustained to the liver. This can occur through either a blunt force such as a car accident, or a penetrating foreign object such as a knife. [1] Liver injuries constitute 5% of all traumas, making it the most common abdominal injury. [2]
A wound is any disruption of or damage to living tissue, such as skin, mucous membranes, or organs. [1] [2] Wounds can either be the sudden result of direct trauma (mechanical, thermal, chemical), or can develop slowly over time due to underlying disease processes such as diabetes mellitus, venous/arterial insufficiency, or immunologic disease.

Causes. Brown-Séquard syndrome may be caused by injury to the spinal cord resulting from a spinal cord tumor, trauma (such as a fall or injury from gunshot or puncture to the cervical or thoracic spine), ischemia (obstruction of a blood vessel), or infectious or inflammatory diseases such as tuberculosis, or multiple sclerosis. In its pure ...
