【摘要】 目的：对乳酸水平及早期乳酸清除率在评估脓毒症预后中的应用价值进行探讨分析。方法：选取本院收治的62例脓毒症患者作为研究对象，根据存亡情况将其分为生存组43例和死亡组19例，对两组患者的乳酸水平和早期乳酸清除率进行观察对比。结果：死亡组患者入院时和入院后6 h的血乳酸水平明显高于生存组，6 h乳酸清除率明显低于生存组，高乳酸清除率组患者的APACHEⅡ评分较低乳酸清除率组患者的APACHEⅡ评分低，两组比较差异均有统计学意义(P<0.05)。严重脓毒症患者的血乳酸水平和APACHEⅡ之间为正相关(r=0.382，P<0.01)，6 h乳酸清除率和APACHEⅡ之间为负相关(r=-0.457，P<0.01)。6 h乳酸清除率<10%患者的死亡率明显高于6 h乳酸清除率≥10%的患者，两组比较差异有统计学意义(P<0.01)。结论：乳酸水平和早期乳酸清除率对脓毒症患者预后的评估效果较好。

    【Abstract】 Objective：To explore the analysis of lactic acid level and the application value of early lactate clearance rate in the assessment of prognosis of septic.Method：62 patients with sepsis were selected as the research objects according to the survival situation and divided into survival group of 43 cases and death group of 19 cases.The two groups of patients with lactic acid levels and early lactate clearance rate were observed and compared.Result：The death group on admission and after admission blood lactic acid level of 6 h was significantly higher than the survival group ......
