摘要:

目的 探讨创伤后脓毒症患者外周血中性粒细胞与淋巴细胞比值(NLR)、血小板与淋巴细胞比值(PLR)和红细胞分布宽度(RDW)变化,阐明其对预后的预测价值。 方法 回顾性分析2021年6月-2025年6月因创伤收入本院重症监护室(ICU)的651例患者临床资料,根据治疗过程中是否并发脓毒症,分为脓毒症组和非脓毒症组;根据脓毒症确诊后28 d内存活状态,进一步将脓毒症组患者分为死亡组和存活组;比较各组患者临床相关指标。采用多因素Logistic回归模型分析脓毒症患者死亡的危险因素,受试者工作特征(ROC)曲线分析各指标对脓毒症患者预后的预测价值。 结果 非脓毒症组纳入患者436例(66.97%),脓毒症组纳入患者215例(33.03%)。脓毒症组患者NLR、PLR和RDW均明显高于非脓毒症组(P<0.05)。脓毒症组患者中,存活组128例(59.53%),死亡组87例(40.47%)。死亡组脓毒症患者的序贯器官衰竭(SOFA)评分、急性生理与慢性健康评估Ⅱ(APACHE Ⅱ)评分、白细胞计数(WBC)、乳酸(LAC)水平、NLR、PLR和RDW均明显高于存活组(P<0.001)。多因素Logistic回归模型,SOFA评分升高、APACHE Ⅱ评分升高、LAC水平升高、NLR升高、PLR升高和RDW升高均为脓毒症患者死亡的危险因素(P<0.05)。ROC曲线分析,LAC、NLR、PLR、RDW、NLR+PLR+RDW联合检测和LAC+NLR+PLR+RDW联合检测ROC曲线下面积分别为0.750、0.699、0.740、0.730、0.835及0.875。 结论 NLR、PLR和RDW升高与创伤后脓毒症的发生及患者不良预后存在关联,上述指标均为脓毒症患者死亡的独立危险因素。联合检测NLR、PLR和RDW对脓毒症患者预后具有一定预测价值。

Abstract:

Objective To investigate the changes of neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), and red cell distribution width (RDW) in the peripheral blood of the patients with post-traumatic sepsis, and to clarify their predictive values for prognosis. Methods The clinical data of 651 patients admitted to the intensive care unit (ICU) due to trauma from June 2021 to June 2025 were retrospectively analyzed. The patients were divided into sepsis group and non-sepsis group according to whether sepsis occurred during treatment. The patients in sepsis group were further divided into death group and survival group regarding their survival within 28 days after confirmed diagnosis of sepsis. The clinical indicators in the patients in various groups were compared. Multivariate Logistic regression model was used to analyze the risk factors for death in the sepsis patients. Receiver operating characteristic (ROC) curve method was used to evaluate the predictive values of the indexes for the prognosis of sepsis patients. Results A total of 436 cases (66.97%) were included in non-sepsis group, and 215 cases (33.03%) were included in sepsis group. Compared with non-sepsis group, the NLR, PLR and RDW of the patients in sepsis group were significantly increased(P<0.05). In the patients with sepsis, 128 cases (59.53%) were included in survival group, and 87 cases (40.47%) were included in death group. Compared with survival group, the Sequential Organ Failure Assessment (SOFA) score, Acute Physiology and Chronic Health Evaluation Ⅱ (APACHE Ⅱ) score, white blood cell count (WBC), lactate (LAC) level, NLR, PLR and RDW were significantly increased in the patients in death group (P<0.001). Elevated SOFA score, elevated APACHE Ⅱ score, elevated LAC, elevated NLR, elevated PLR, and elevated RDW were the independent risk factors for death in sepsis patients (P<0.05). The areas under the curve (AUCs) of LAC, NLR, PLR, RDW, combined detection of NLR, PLR and RDW, and combined detection of LAC, NLR, PLR and RDW were 0.750, 0.699, 0.740, 0.730, 0.835, and 0.875, respectively. Conclusion Elevated NLR, PLR and RDW are associated with the occurrence of post-traumatic sepsis and poor prognosis of patients. The above indices are independent risk factors for death in sepsis patients. Combined detection of NLR, PLR and RDW shows certain predictive value for the prognosis of sepsis patients.
