【摘要】 目的根据小样本严重意识障碍患者纵向研究,对常用临床意识量表进行评估。方法选取在武警杭州医院脑康复中心2005年6月至2006年2月间进行了唤名刺激脑功能成像(fMRI)检测的11名严重意识障碍患者进行前瞻性研究。用常用意识量表对11例严重意识障碍患者进行评分,并在fMRI检测后3个月用改进的昏迷康复量表(CRS-R量表)进行每月一次跟踪检测。以CRS-R量表的纵向评分分值结合fMRI研究结果作为患者分组依据,对各意识量表的总分和子项目分值进行One-Way ANOVA组间差异性分析。结果在所有项目中,除了CRS-R量表中的交流子量表(P=0.019),其他项目的组间差异无统计学意义;在受评意识量表中,Wessex脑损伤模块(WHIM)在总体上的组间差异无统计学意义(P=0.066),中国植物状态评估量表(CVSS)的组间差异无统计学意义(P=0.866)。结论用客观方法对常用意识量表及子项目的评估结果表明各量表及子项目的诊断价值总体较差,项目之间的诊断价值存在较大差异。更多还原

【Abstract】 Objective To evaluate the commonly used consciousness scales according to longitudinal study on small-sample patients with minimally conscious state. Method Eleven patients with minimally consciousness, who were scanned using fMRI, were selected and scored by the commonly used consciousness scales in Wujing Hangzbeu Hospital. The 11 patients were classified into 2 groups according to the scores of CRS-R scale couple with the results of the fMRI study. The One-Way ANOVA method was used to analyze the inter-group difference of the commonly used consciousness scales and their subscales. Results Despite the communicative subscale of the CRS-R scales, other iterms lack of statistic significance in classification of the conscious state. Among the commonly used consciousness scales, the Wessex Head Injury Matrix (WHIM) scale presented the highest diagnostic value in consciousness state, whereas the Chinese Vegetative State Scale (CVSS) presented the lowest diagnostic value. Conclusions It indicated that the total scores of the consciousness scales and the scores of subscales of them presented poor diagnostic value in general, and big discrepancy of diagnostic value existed between the iterms of the scales by using objective tools.更多还原
