【摘要】：目的探讨红细胞分布宽度(RDW)对重症肺炎患者预后的评估价值。方法选择101例重症肺炎患者,记录其RDW、超敏C反应蛋白(hs-CRP)、降钙素原(PCT)、CURB-65评分及28 d转归情况。分析存活组与死亡组、RDW正常组与RDW升高组间RDW、hs-CRP、PCT、CURB-65评分的差异,并评估上述指标对重症肺炎预后的预测能力。结果死亡组的PCT、RDW及CURB-65评分显著高于存活组(P0.05),两组间hsCRP差异无统计学意义(P0.05)。RDW升高组的年龄、RDW及CURB-65评分显著高于RDW正常组(P0.05)。RDW预测重症肺炎患者死亡的ROC曲线下面积均大于PCT、hs-CRP及CURB-65评分(P0.05),其对重症肺炎患者死亡的最佳预测值为14.85,该值具有较高的敏感度(0.931)和特异度(0.778)。结论 RDW有助于判断重症肺炎的病情严重程度,具有良好的预后预测价值。
[Abstract]:Objective to evaluate the prognostic value of RDW in patients with severe pneumonia. Methods 101 patients with severe pneumonia were selected to record their RDW, Hs-CRP, procalcitonin (PCT), CURB-65 score and 28 days outcome. To analyze the difference of RDWhs-CRPRDW CURB-65 score between the survival group and the death group, and to evaluate the predictive ability of the above indexes for the prognosis of severe pneumonia. Results the scores of hsCRP and CURB-65 in the death group were significantly higher than those in the survival group (P 0.05). There was no significant difference in hsCRP between the two groups. The age and CURB-65 scores in the group with elevated P0.05U. RDW were significantly higher than those in the normal RDW group under the ROC curve of predicting the death of patients with severe pneumonia. Higher than PCT hs-CRP and CURB-65 score (P 0.05), the best predictive value for death of severe pneumonia patients was 14.85, with a high sensitivity of 0.931) and specificity of 0.778g. Conclusion RDW is helpful to judge the severity of severe pneumonia and has good prognostic value.
