Internal bleeding (also called internal haemorrhage) is a loss of blood from a blood vessel that collects inside the body, and is not usually visible from the outside. [1] It can be a serious medical emergency but the extent of severity depends on bleeding rate and location of the bleeding (e.g. head, torso, extremities).
A hemothorax (derived from hemo-[blood] + thorax [chest], plural hemothoraces) is an accumulation of blood within the pleural cavity.The symptoms of a hemothorax may include chest pain and difficulty breathing, while the clinical signs may include reduced breath sounds on the affected side and a rapid heart rate.
Certain penetrating neck injuries can also cause cervical fracture which can also cause internal bleeding among other complications. Execution by hanging is intended to cause a fatal cervical fracture. The knot in the noose is placed to the left of the condemned, so that at the end of the drop, the head is jolted sharply upwards and to the ...
It comes from a provider's exam and the patient's history. [5] [14] Diagnosis may also require measuring intracompartmental pressure. [5] [6] Using both methods increases the accuracy of diagnosing compartment syndrome. [46] A transducer connected to a catheter is inserted 5 cm into the zone of injury to measure the intracompartmental pressure.
It runs down the side of the neck in a vertical direction, being at one end lateral to the internal carotid artery, and then lateral to the common carotid artery, and at the root of the neck, it unites with the subclavian vein to form the brachiocephalic vein (innominate vein); a little above its termination is a second dilation, the inferior bulb.
Diagram showing parts of the body that drain into the right lymphatic duct. The lymph transport, in the thoracic duct, is mainly caused by the action of breathing, aided by the duct's smooth muscle and by internal valves which prevent the lymph from flowing back down again. There are also two valves at the junction of the duct with the left ...
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.
Gunshots to the neck can thus cause severe bleeding, airway compromise, and nervous system injury. [ 29 ] Initial assessment of a gunshot wound to the neck involves non-probing inspection of whether the injury is a penetrating neck injury (PNI), classified by violation of the platysma muscle. [ 29 ]
