摘  要:目的探讨红细胞分布宽度(RDW)对脓毒症患者预后的评估价值。方法回顾性分析2011年1月至2016年12月苏州大学附属第一医院重症医学科(ICU)收治的脓毒症患者的临床资料,收集患者的一般情况、主要基础疾病、感染部位、急性生理学与慢性健康状况评分系统Ⅱ(APACHEⅡ)评分、血常规、血生化、血气分析、凝血指标、降钙素原(PCT)、住院时间、28 d和90 d病死率。根据出院时RDW值是否高于入院时将患者分为RDW升高组和非升高组,比较两组临床特征,采用Kaplan-Meier生存曲线分析两组28 d和90 d累积生存率,采用多因素Cox回归分析脓毒症患者死亡的独立危险因素。结果入选196例脓毒症患者中有105例(53.57%)出院时RDW值高于入院时。与RDW非升高组比较,RDW升高组APACHEⅡ评分明显升高(分:20.42±6.29比16.17±6.37),合并慢性肾功能不全比例(35.24%比19.78%)、血流感染比例(32.38%比15.38%)、行连续性肾脏替代治疗(CRRT)比例(32.38%比16.48%)均明显升高,C-反应蛋白〔CRP (mg/L):14.71±3.52比11.15±7.94〕、血肌酐〔SCr(μmol/L):128.0(74.0,263.5)比90.0(57.0,145.5)〕、PCT〔μg/L):3.45(2.39,6.64)比2.35(0.56,3.54)〕、乳酸(mmol/L:3.40±1.72比2.70±1.61)均明显升高,血细胞比容(Hct:0.357±0.128比0.437±0.143)、血红蛋白〔Hb(g/L):103.60±22.63比115.67±28.49〕、血小板计数〔PLT(×109/L):133.37±87.29比191.43±87.65〕、白蛋白〔Alb(g/L):28.15±5.72比35.51±5.91〕、总胆固醇〔TC(mmol/L):2.43±1.12比3.05±1.55〕、肾小球滤过率〔eGFR(mL·min-1·1.73 m-2):82.02±63.90比125.46±83.47〕、氧合指数〔PaO2/FiO2(mmHg,1 mmHg=0.133 kPa):229.69±60.61比264.21±74.78〕均明显降低,住院时间明显延长〔d:17.0(12.0,21.7)比11.0(7.0,18.0)〕,28 d和90 d病死率明显升高(57.14%比36.26%,62.86ObjectiveTo investigate the association of red cell distribution width (RDW) with prognosis in patients with sepsis.MethodsPatients with sepsis admitted to intensive care unit (ICU) of the First Hospital of Soochow University from January 2011 to December 2016 were enrolled. All clinical data were collected for participants, which mainly included basic data, main underlying disease, site of infection, acute physiology and chronic health evaluation Ⅱ(APACHE Ⅱ) score, blood routine test, biochemical test, blood gas analysis, coagulation index, procalcitonin (PCT), hospitalization days, and 28-day and 90-day mortality. Patients were divided into two groups according to whether the RDW levels were higher than the time of admission or not. Kaplan-Meier survival curve was performed to analyze 28-day and 90-day cumulative survival rates in two groups. Multivariate Cox regression analysis was done to find the independent risk factors of death in patients with sepsis.Results196 septic patients were eligible to participate into this study. 150 patients (53.57%) had higher RDW levels than those at the time of admission. Compared to negative or static change of RDW group, positive change of RDW group had higher APACHE Ⅱ score (20.42±6.29 vs. 16.17±6.37), more percentage of chronic kidney insufficiency (35.24% vs. 19.78%), bloodstream infection (32.38% vs. 15.38%), continuous renal replacement therapy (CRRT: 32.38% vs. 16.48%), higher level of C-reactive protein [CRP (mg/L): 14.71±3.52 vs. 11.15±7.94], and higher serum creatinine [SCr (μmol/L): 128.0 (74.0, 263.5) vs. 90.0 (57.0, 145.5)], PCT [μg/L: 3.45 (2.39, 6.64) vs. 2.35 (0.56, 3.54)], and lactic acid [Lac (mmol/L): 3.40±1.72 vs. 2.70±1.61]; and had lower levels of hematocrit (Hct: 0.357±0.128 vs. 0.437±0.143), hemoglobin [Hb (g/L): 103.60±22.63 vs. 115.67±28.49], platelets [PLT (×109/L): 133.37±87.29 vs. 191.43±87.65], albumin [Alb (g/L): 28.15±5.72 vs
