Diffuse axonal injury


Common rule for five years, we have cases of 46 cases of DAI, it is the mechanism of their clinical conditions, such as characteristics, where key points are discussed. 1 of 11 general clinical data in 46 cases, 37 males. Female 9 down; ages 6 to 74 years old. Average of 35-year-old cause of his injuries: 35 cases of traffic accidents. Falls from a height of 10 Li, falls in 1 case: injury to eight hospital time: 30 minutes to 8 hours. Clinical features of 12 when the eight hospital G (: 3 points in 8 cases, 14 cases of 4 to 5 harsh Shu .6 ~ .9 ~ 10 of 20 cases in 4 cases. Limb increased muscle tone (some 125 cases were decerebrate rigidity. Central high fever 28. complications. especially Asr inflammation and / or gastrointestinal bleeding more common, and difficult to control. inflammation of the group had 26 cases, 14 cases of gastrointestinal bleeding. traumatic coma recovery time to the minimum 10 days. most of the Gan 【course within three months except for death and plants should be 113 Jing cT imaging features typical of the performance of a wide range of brain tissue to the midline mainly edema, swelling, often accompanied by hemorrhage under the spider A membrane (SAH ~ 35 patients with particular brain hemorrhage thousands more obvious around the pool. ventricles, sulci, smaller pool of 28 cases of brain or even disappeared in 15 cases. parenchyma often have different degrees of density change. contusion in 28 patients with higher density, slightly low density 16 sides . such as Taiwan and other diseases castrate l l blood red, etc.) may have a corresponding performance. 2 treatment results, Section 8 sides. c2} mild disability: a hemiparesis, mild brain dysfunction, but it can take care of themselves living in this group in 5 cases. 【3) severely disabled: a full-body paralysis on one side or significant brain dysfunction. can not take care of themselves life. The group of 7 cases. (4) 4 Li c5} plant life died: 22 patients. 3 to discuss the mechanism of 31 patients with head injuries was in motion and rotation occurs. rotation also occurred in brain tissue, so. brain tissue to because of the role of shear stress caused by injury. midline causing damage mainly to the detriment of the broader anti-/ 'f [f · 315 · variation. patients often unconscious. degeneration occurs late axis. lead to severe disability, vegetative state, death. mortality rate is high. The mortality of 476%. 32 Zhao 1991 diagnose DAI's other proposed diagnostic criteria, 'but we believe that the pool of blood around the brain stem DAI is an important diagnostic sign, if combined with large intracranial hematoma, also with mass performance. of the view that the following few. DAI can be used as diagnostic criteria: ① head injuries was in motion. external force to the head produces shear stress; ⑦ primary coma, the duration of the saddle a long,[link widoczny dla zalogowanych], often accompanied by central high fever and increased muscle tone; 0 midline head CT appears location-based contusion, swelling and bleeding. even if the brain stem bleeding around the pool is a typical sign. 33 points nAI serious condition treatment, the mortality rate is very high. must take comprehensive measures. but the following points are noteworthy: ① control of high fever . our regular treatment of mild hibernation. will be temperature controlled at about 33 ~ 34 ℃. ⑦ high-dose dexamethasone. made by Shanghai Changzheng Hospital, a large dose of dexamethasone application of standard practice, the effect is better. for the first time medication should be sooner the better. 0 prevention of complications. complication to pneumonia and acute gastric bleeding erosions film revolves up. The author believes that in the event of pneumonia. should not be tangled by the escalation of conventional antibiotic solution, and should be immediately given three generations of cephalosporin antibiotics such as orderly and efficient, sought to control the infection as soon as possible. gastrointestinal hemorrhage after intravenous omeprazole is better. ④ 3AH and treatment of cerebral vasospasm. SAI {often cause cerebral vasospasm. is the leading cause of death post-traumatic brain injury, early ventricular drainage or lumbar puncture is a simple and effective method, but also to understand the situation of intracranial pressure. Some advocate early lifting of nimodipine treatment on cerebral vasospasm in SAH benefit. In this regard, we have no statistics.
