Radionuclide imaging diagnosis of ectopic gastric mucosa: clinical observation of 22 cases, result related to local skin cleaning. The Second Hospital of Peking University, 030001, on the treatment of acute subdural hematoma at Houma Municipal People's Hospital (043000) cross-country Jun Weiqiu Yan. Subdural hematoma is a common disease in neurosurgery for intracranial hematoma, about 4O (3D), acute subdural hematoma occurs at a high rate, 7O. The bleeding source is from contusion and laceration of the brain surface blood vessels; simple bridging vein injury induced is rare, often with cerebral contusion and laceration, hematoma coexisting, difficult to cure, effect is poor. Literature reports a case fatality rate of 42.62%. This paper analyzes 150 cases of acute subdural hematoma treated, with a case fatality rate of 42.67%, report as follows. 1 Clinical data: this group of 150 patients, 125 were male, 25 female; aged 6 months to 87 years, mean age 36.5 years. Traffic injury in 74 cases, fall injury in 35 cases, injuries in 25 cases, combat injury in 6 cases, other 10 cases. The injury to admission time was 40 minutes to 72 hours, average 13.4 hours. Hematoma site: forehead in 32 cases, frontal and temporal lobe in 63 cases, frontal temporal top in 27 cases, top in 10 cases, posterior temporal, and occipital top in 8 cases, bilateral in 10 cases (bilateral simultaneous operation in 1 case, more than one operation), which merged with skull fractures in 83 cases, while 52 conscious cases, mild coma in 20 cases, moderate in 38 cases with severe coma, 40 patients, including 35 cases of pupil change. Decerebrate rigidity in 6 cases, cerebral hernia in 32 cases. The volume of hematoma <30mL42, 30~40mL22, 41~80mL69, 81~150mL17 cases. Glasgow Coma Scale (GCS) type 30 patients: light, medium in 95 cases, severe 25 cases. 2 Results: emergency operation in 85 cases after operation, 24 hours 40, at the same time to the bone plate decompression in 36 cases, 25 non-operation treatment cases. When discharged, patient made a good recovery in 43 cases, 9 cases of residual light, moderate disability in 28 cases, severe disability in 5 cases, plant survival of 1 case, 64 cases of death. GCS typing: Light 2 cases of death, and death in 41 cases, 21 severe death cases. 3 Discuss: 3.1 Emergency room emergency treatment and diagnosis. 3.1.1 Emergency room emergency: includes keeping the respiratory tract unobstructed, stop bleeding, correct shock, L-pulmonary resuscitation, for follow-up treatment for conditions, avoid double damage. In addition to the emergency room emergency must contain the correct diagnosis and treatment of combined injury. 3.1.2 Emergency room diagnosis: includes two aspects: acute subdural hematoma is complex or simple and combined diagnosis. Acute subdural hematoma diagnosis must be clear in the shortest possible time, determine whether the need immediate operation indication. As the condition of the wounded by GCS classification, determines whether the income home or stay observation. 3.2 Correct, timely and reasonable operation. 3.2.1 Operation indications: once found that the hematoma with mass effect, should be immediately craniotomy operation, so as not to delay the rescue time, especially the formation of cerebral hernia cases should make every effort to shorten preoperative preparation time. Yang Kaiyong reported preoperatively state of consciousness and pupillary changes on treatment effect is very large. 3.2.2 Operation mode: used for window of bone or bone flap craniotomy. For hematoma clear positioning of patients. Muscle under decompression or decompressive craniectomy for severe cerebral contusion and laceration of brain edema, or the patient complicated with brain swelling. 3.2.3 Surgery should be aimed at different situations with proper treatment of multiple trauma: focal treatment of acute subdural hematoma: common sources of bleeding is damage to the brain parenchyma vessel. Brain injury range significantly affect treatment outcome. Injuries range is bigger, more hurt foci, treatment effect worse. With multiple brain injury lesions of acute subdural hematoma after removal, probably because of intracranial pressure drop or vascular causes, and the emergence of tardive or multiple subdural or epidural hematoma; if broken down tissues not handled properly, easy occurrence of postoperative wound cavity bleeding. Broken brain tissue characteristics are color is dark gray, suck without bleeding, crunchy texture, easy to suck. If the presence of bilateral hematoma, should be based on clinical symptoms and hematoma volume comprehensive consider the need for a simultaneous operation. If it must be at the same time operation should first remove the epidural hematoma, subdural hematoma after removal, this paradox can alleviate as soon as possible intracranial pressure, but also can avoid the subdural hematoma after intracranial pressure drops make epidural hematoma volume increases and aggravate cerebral dislocation. If both sides is a subdural hematoma, should first remove the large volume causing midline shift, so as not to aggravate the brain shift. The inner decompression (or vacuum) should be fully: intraoperative decompression is not satisfied with the common causes of removal of the hematoma brain swelling. The hematoma and brain injury lesions located in the dominant hemisphere or the adjacent important functional areas are often impact pressure. In such cases, removal of bone flap decompression is up and means, but the effect is poor, therefore the operation should fully inside decompression.
