1、脓毒症患者动态监测肌钙蛋白I的意义作者:谭成戊龚仕金严静许强宏戴海文【摘要】目的 动态测定脓毒症患者肌钙蛋白I的变化,探讨肌钙蛋白I用于脓毒症患者病情和疗效评估方面的价值。方法 分别测定脓毒症患者入院时、入院后第3天和第7天的肌钙蛋白I浓度,分析不同时点与相同时点的APACHEII评分、ICU病死率和28d生存率之间的相关性,比较不同时间点肌钙蛋白I升高组(cTnI>0.1ng/ml)和正常组(cTnI<0.1ng/ml)的ICU病死率和28d生存率。结果 66例脓毒症患者中有47例患者肌钙蛋白I升高,升高率达到71.21%。患者入院时和入院后第3天的肌钙蛋白I的浓度与对应的AP
2、ACHEⅡ评分呈正相关(r分别=0.37、0.34,P均<0.05),与ICU病死率成正相关(r分别=0.34、0.36,P均<0.05),与28d生存率呈负相关(r分别=-0.39、-0.42,P均<0.05);入院后第7天患者肌钙蛋白I的浓度虽与同时点APACHEⅡ评分没有相关性(r=0.21,P>0.05),但是与ICU病死率和28d生存率具有相关性(r分别=0.37、-0.42,P均<0.05)。患者入院时、入院后第3天和入院后第7天,肌钙蛋白I升高组的ICU病死率明显高于正常组,差异均有统计学意义(χ2分别=-2.21、-3.06、-3.35,P均<0.05);而28d
3、生存率低于正常组,差异均有统计学意义(χ2分别=-2.40、-3.13、-3.78,P均<0.05)。结论 脓毒症患者肌钙蛋白I的测定可以有助于临床医生早期进行病情判断,并且对疾病的预后也有较高的预测价值。【关键词】脓毒症; 肌钙蛋白I; 预后MeasurementofcardiactroponinIinsepsispatientsTANChengwu,GONGShijin,YANJing,etal.IntensiveCareUnit,ZhejiangHospital,Hangzhou310013,ChinaAbstractObjectiveToinvestigatecardia
