摘　　要：目的通过与简易精神状态量表（MMSE）的比较，评估Loewenstein认知评定量表（LOTCA）是否能用于术后认知障碍（POCD）的诊断与研究。方法对山东省立医院心外科自2010年10月至2011年3月行心脏瓣膜置换术的30例患者，分别于术前1d和术后7d使用MMSE、LOTCA行神经心理学测评患者的认知功能，分析比较二者对POCD的诊断率、MMSE和LOTCA评分及检测时间的差异。结果患者采用MMSE测评诊断POCD13例（43．33％），采用LOTCA测评诊断POCD17例（56．67％），诊断率比较差异无统计学意义怍1．067，P=-0．302）。与术前1d比较，术后7d患者MMSE总分、LOTCA总分、LOTCA评分中4个子项目（动作运用、视运动组织、思维操作、注意力及专注力）得分降低，差异均有统计学意义（P〈0．05）。患者MMSE总分与LOTCA总分呈正相关关系（γ=0．711，P=0．005）。与MMSE的测评时间比较、患者术前1d和术后7dLOTCA的测评时间均较高，差异有统计学意义（P〈0．05）。结论LOTCA可以用于POCD的诊断与研究，能够较MMSE更全面的评估患者的认知功能，但耗时较长。Objective To evaluate whether Loewenstein occupational therapy cognitive assessment （LOTCA） can be used in the diagnosis of postoperative cognitive dysfunction （POCD） by comparing it with mini-mental state examination （MMSE）. Methods Thirty patients performed cardiac valve replacement surgery in our hospital from October 2010 to March 2011 were chosen; the cognitive function of these patients were neuropsychologically evaluated by MMSE and LOTCA 1 d before and 7 d after the surgery; the differences of accurately diagnostic rate on POCD, the scores and the time-consuming when MMSE and LOTCA were chosen were compared. Results Thirteen patients （43.33%） were diagnosed as having POCD by MMSE and 17 patients （56.67%） by LOTCA; the difference of accurately diagnostic rate on POCD was not statistically significant （χ2=1.067, P=-0.302）. MMSE scores, LOTCA scores and scores of 4 subtests （motor praxis, visuomotor organization, operation of thinking, and attention and concentration） 7 d after the surgery was significantly decreased as compared with those 1 d before the surgery （P〈0.05）. MMSE scores were highly correlated with LOTCA scores （y=0.711, P=-0.005）. Conclusion LOTCA can be used in the diagnosis and research of POCD. It can do a more comprehensive assessment than MMSE in cognitive function with longer times.
