结果
RESULTS: Delirium was identified in 53 patients (22%); 162 patients (68%) had completed only 4 years of education. On multivariable analysis, probable cognitive impairment tested by the Mini-Cog (odds ratio [OR] = 1.57; 95% confidence interval [CI], 0.70–3.53; corrected P value >.999), by the Mini-Mental State Examination (OR = 2.75; 95% CI, 1.23–6.13; corrected P value = http://news.hoteastday.com/a/.052), and by the animal verbal fluency test (OR = 1.24; 95% CI, 0.49–3.16; corrected P value >.999) were not significantly associated with the development of postoperative delirium. In contrast, lower preoperative Scto2 (OR = 1.08; 95% CI, 1.02–1.14; corrected P value = .024 for each point decrease in Scto2) was associated with postoperative delirium.
结果:（本研究共纳入238名患者）53例(22%)患者出现谵妄;162名患者(68%)仅完成了4年的教育。在多变量分析中，通过Mini-Cog测试出的可能的认知障碍(OR0.91; 95%CI : 0.70-3.53; 校正P值>.999) ，简易智力状态检查测试出的可能的认知障碍(OR2.75; 95%CI : 1.23-6.13 ; 校正P值>.999) ，以及语言流畅性测试出的可能的认知障碍(OR1.24;95%CI : 0.49-3.16 ; 校正P值>.999)与术后谵妄的发生无显著相关性。相比之下，术前Scto2较低(1.08; 95%CI : 1.02-1.14; Scto2每降低1 ，校正P值= .024)与术后谵妄相关。

结论
CONCLUSIONS: We did not find enough evidence to suggest that poor preoperative cognitive performance was significantly associated with the development of postoperative delirium in an older Portuguese surgical population with an overall low level of formal education, but rather that preoperative Scto2 may be helpful in identifying patients at risk for delirium.
结论：我们发现无足够的证据表明在整体正规教育水平较低的葡萄牙老年外科患者中，术前认知能力差与术后谵妄的发生有显著相关性。然而术前Scto2可能有助于识别有谵妄风险的患者。
