血小板计数和APACHEⅡ评分对脓毒症预后的影响

摘要

Objective To investigate the significance of platelet counts and APACHE Ⅱ scores in the estimation and prediction of the sepsis.Methods The platelet counts and the APACHE Ⅱ were detected in 151 patients admitted to ICU at the first day.The patients were divided into group A ( ＜ 15 scores), group B( 15 ～20 scores)and group C ( ＞ 20 scores)according to APACHE Ⅱ scores.The platelet counts and prognosis were analyzed.All the patients were divided into survival group and death group according to the prognosis, and the plgtelet counts and the APACHE Ⅱ scores were compared between two groups.Results The platelet counts were the highest in group A, then in group B and group C(P ＜0.01).The mortality was the lowest in group A, then in group B and group C(P ＜0.05).The APACHE Ⅱ scores in the survival group were obviously lower than those in the death group(P ＜0.01 ), and the platelet counts in the survival group were significantly higher than those in the death group(P ＜0.01).Conclusion The platelet counts and the APACHE Ⅱ scores can make accurate diagnosis for sepsis and predict the prognosis.%目的 探讨血小板计数、急性生理和慢性健康状况评分Ⅱ (APACHEⅡ)在评定和预测脓毒症中的意义.方法 对151例脓毒症患者于入院第1天进行血小板计数测定和APACHEⅡ评分,并按APACHEⅡ评分分为A组(＜15分)、B组(15~20分)、C组(＞20分),分析各组患者的血小板计数和预后.根据预后分为生存组和死亡组,比较两组血小板计数和APACHEⅡ评分.结果 A组血小板计数明显高于B、C组(P<0.01),B组明显高于C组(P<0.01).A组死亡率明显低于B、C组(P<0.05),B组明显低于C组(P<0.05).生存组APACHEⅡ评分明显低于死亡组(P<0.01),血小板计数明显高于死亡组(P<0.01).结论 血小板计数和APACHEⅡ评分能准确反映脓毒症患者的病情和预后.
