Closed traumatic brain injury

Blunt outlined many of brain injury traffic accidents, falls, crashes and other injuries in the accident caused injuries. More common in wartime fortifications reversing hurt or explosion caused by high pressure gas shock wave injuries, violence, directly or indirectly head injuries. Cause pathogenesis of closed brain injury more complex mechanism, the vast majority of brain injury is often the mechanism by several factors, and many of the results. Its main wounding two factors : (1) As the deformation of the skull fractures caused brain injury; (2) As the brain tissue within the cranial cavity linear or rotary movement caused by the brain injury. 1. Direct damage : (a) accelerate the injury : a movement of objects in static impact on the head by the brain injury, If hit with sticks or stones. (2) deceleration injury : that the campaign to head encounter static objects and injuries, such as crashes and falls. (3) The crush injury : two different directions while the role of foreign forces in the head, so that deformation of the skull injury. 2. Indirect injury : transfer injury : If falling to the buttocks or when a biped, outside along the spine injuries transmitted to the skull base; Lut-whip injury : This injury occurs most often in the craniocervical junction. Squeeze chest injury with brain injury : results from an intense chest squeezed, suddenly increased intrathoracic pressure on the jugular transmitted to the brain injury. Symptoms of consciousness : changes in the extent and severity of the judgment is important; Scalp injury, ear, nose bleeding and fluid; Vital Signs (respiration, pulse, blood pressure and body temperature) change; intracranial hypertension; bulbar dysfunction; shock; Pupil size, The shape and light reaction changed; Movement and the reflection change. Censorship (1) Skull X-ray films : as long as conditions permit should be checked as is, the lateral films, or special place. (2) lumbar puncture : to understand cerebrospinal fluid pressure and ingredients change. (3) Ultrasonic Inspection : hematoma on the right screen can be middle-displacement, will determine hematoma side, but no displacement, can not be ruled out hematoma. (4) cerebral angiography : an accurate diagnosis of intracranial hematoma is higher. (5) CT and MRI, the diagnosis of traumatic brain injury also be of significance
