作者用EEG、体感诱发电位(SEPs)中的中枢传导时间(CCT)、格拉斯哥昏迷评分(GCS)对严重头伤(SHI)患者进行测定,并与1.5年后的病人预后比较,对用EEG活动预测SHI预后的价值进行了研究。 本研究的病例选择标准是年龄14～35岁。无滥用药物、精神疾患或颅脑外伤史。符合本标准的50名病人平均年龄30岁,平均昏迷13天(2～60天)。其中22名病人GCS为3～4分,16名的GCS为5～6分,12名的GCS为7～8分。伤后48～72小时内作EEG和SEPs记录,所有病人均用Midozolam镇静,而不用巴比妥类药物。行常规EEG描记,外加强声和痛刺激,由两名评估者单独目测图纸,得出四种结果,即24％的病人有慢波发放,30％病人描图平坦,18％的病员EEG活动视为可疑,28％的患者EEG
The authors measured severe head injury (SHI) in patients with severe head injury (SHI) using EEG, central conduction time (CCT) in somatosensory evoked potentials (SEPs), and Glasgow coma score (GCS) and compared with patient prognosis after 1.5 years The value of predicting SHI prognosis was studied. The case selection criteria for this study were 14-35 years of age. No abuse of drugs, mental illness or history of traumatic brain injury. The 50 patients in line with this standard mean age 30 years, the average coma for 13 days (2 to 60 days). Among them, 22 patients had GCS of 3 to 4, 16 GCS of 5 to 6 and 12 GCS of 7 to 8. EEG and SEPs were recorded 48 to 72 hours after injury, and all patients were sedated with Midozolam instead of barbiturates. Routine EEG tracings, combined with strong ache and painful stimuli, were visually inspected visually by two assessors and resulted in four outcomes: 24% of patients had slow wave delivery, 30% of patients were flat and 18% of patients had EEG activity Suspected, 28% of patients with EEG
