呼吸衰竭患者不同预后评分的比较

目的：试图比较现行三种预后评分对呼吸衰竭患者预后的判别能力；方法：选取2009年1月-2012年3月入住本院符合呼吸衰竭诊断标准的138例患者，应用三种不同评分（APACHEⅡ，APACHEⅢ和SAPSⅡ）评估其预后情况，根据入院30 d存活情况比较不同评分的预测能力。结果：死亡组患者三种评分分值均明显高于存活组，同时ICU住院天数明显短于存活组，差异均有统计学意义（P〈0.001）；其中SAPSⅡ敏感度最高，三种评分受试者工作曲线的曲线下面积均在0.8以上。结论：现行三种评分均可较好地预测呼吸衰竭患者的预后，值得临床推广。

Comparison of Different Scoring Systems in Patients with Respiratory Failure

Objective：To investigate the capability of three scoring systems in patients with respiratory failure. Method：138 patients diagnosed as respiratory failure admitted to our hospital from January 2009 to March 2012 were selected, and evaluated their prognosis with three scoring systems（APACHE Ⅱ,APACHE Ⅲand SAPSⅡ）,and according to the admission of 30 d survival,the predictive ability of these scoring systems were compared.Result：Prognosis scores of three scoring systems in the death group were significantly higher than those of the survival group,at the same time,length of ICU stay was significantly shorter than the survival group,the differences were statistically significant（P〈0.001）.Among them SAPS Ⅱwas the highest sensitivity,the area under curve of ROC of the three systems were all above 0.8.Conclusion：The existing three scoring can well predict the prognosis of patients with respiratory failure,is worthy of clinical promotion.
