选取神经外科住院患者147例为研究对象。利用Sysmex 4000全血细胞分析仪检测患者红细胞分布宽度( RDW)、血红蛋白( Hb)、白细胞计数( WBC)、红细胞平均体积( MCV)等指标,根据患者的各项生理参数和实验室检查结果的进行急性生理功能和慢性健康状况Ⅱ评分(A-PACHE-Ⅱ),同时运用受试者工作特征曲线( ROC曲线)评价RDW对重型颅脑损伤患者住院死亡率的预测价值。重型颅脑损伤患者RDW值随着APACHE Ⅱ评分和患者死亡率的增高而逐渐升高,且3组间RDW值差异有统计学意义(P<0．05)。 ROC曲线分析显示,当RDW和APACHE Ⅱ评分在预测重型颅脑损伤患者住院死亡率时的曲线下面积分别为0．68和0．61,两者联合曲线下面积为0.71。

A total of 147 consecutive patients were prospectively enrolled. We collected each patient’ s base-line characteristics including the Acute Physiology and Chronic Health Evaluation Ⅱ ( APACHE-Ⅱ) score, red cell distribution width ( RDW ) , hemoglobin ( Hb ) , white blood cell count ( WBC ) and mean corpuscular volume ( MCV) . By ROC curve analysis,the sensitivity and specificity of RDW were estimated in identifyng the mortality in patients hospitalized with severe traumatic brain injury. There was a significantly graded increase in APACHE-Ⅱscore and the mortality in patients hospitalized with severe traumatic brain injury across increasing of RDW. The ar-ea under the curve ( AUC ) of RDW, APACHE-Ⅱ score and combination of RDW and APACHE-Ⅱ score were 0. 68 ,0. 61 and 0. 71 .
