PICU脓毒血症患者血小板计数、D-二聚体水平与小儿危重病例评分及预后相关性

观察PICU收治脓毒血症患者血小板计数、D-二聚体水平与小儿危重病例评分及预后的相关性。选择本院PICU2013年01月—2014年12月入住PICU临床资料完整的85例脓毒血症患者为研究对象进行回顾性分析。根据危重病例评分分值分为3组,非危重组(80评分值100)、危重组(70评分值80)和极危重组(0评分值70分),入PICU后抽取血样测定血小板计数、D-二聚体水平,行小儿危重病例评分,分析血小板计数、D-二聚体水平与小儿危重病例评分相关性。观察患者预后情况发现,极危重组患者血小板计数明显低于危重组患者(t=5.23,P0.01)、非危重组患者(t=2.18,P0.01);而极危重组患者D-二聚体水平明显高于危重组患者(t=3.46,P0.01)、非危重组患者(t=9.58,P0.01);极危重组患者病死率明显高于危重组患者(X2=16.45,P0.01)、非危重组患者。死亡组患者的小儿危重病例评分分值明显低于存活组(t=3.35.P0.05),而D-二聚体水平明显高于存活组(t=9.63,P0.05);血小板计数明显低于存活组(t=4.23,P0.05)。差异均有统计学意义。血小板计数、D-二聚体水平与小儿危重病例评分均显著相关。随着小儿危重病例评分下降,血小板计数相应下降,D-二聚体水平相应增高;D-二聚体水平与病情严重程度正相关,血小板计数则与病情严重程度负相关,是病情严重程度的早期、敏感、定量的指标。

Correlation Between Platelet Count and D-two Level in Patients with PICU Septicopyemia and Pediatric Critical Illness Score PCIS and Prognosis

Correlation between platelet count and D-two levels in patients with PICU septicopyemia and critical illness score and prognosis in children was observed.85 cases of sepsis patients with complete PICU clinical data stayed in the hospital PICU from January 2013 to December 2014 were selected,a retrospective analysis was performed.They were divided into 3 groups according to the scores of critical cases,that was non critical group (80 < score < 100),critical group (70 < score < 80)and extremely critical group (0
