目的探讨红细胞体积分布宽度(red cell volume distribution width,RDW)对心脏停搏(cardiac arrest,CA)患者预后的评估价值。方法回顾性分析2018年1月至2022年10月湖州市中心医院重症监护室(intensive care unit,ICU)收治的146例CA患者...目的探讨红细胞体积分布宽度(red cell volume distribution width,RDW)对心脏停搏(cardiac arrest,CA)患者预后的评估价值。方法回顾性分析2018年1月至2022年10月湖州市中心医院重症监护室(intensive care unit,ICU)收治的146例CA患者的临床资料,根据ICU住院期间预后将患者分为存活组和死亡组,比较两组患者的临床资料,采用多因素Logistic回归分析影响CA患者预后的危险因素。采用受试者操作特征曲线(receiver operating characteristic curve,ROC曲线)评估RDW对CA患者预后的预测效能。Kaplan-Meier法绘制患者生存曲线。结果共纳入146例CA患者,其中存活49例,死亡97例,死亡率66.44%。死亡组患者的急性生理学和慢性健康状况评价Ⅱ评分、RDW、血钠、丙氨酸转氨酶均显著高于存活组,心肺复苏时间显著长于存活组,ICU住院时间显著短于存活组(P<0.05)。多因素Logistic回归分析结果显示,RDW、心肺复苏时间均是CA患者ICU住院期间死亡的独立危险因素(P<0.05)。ROC曲线结果显示RDW预测CA患者死亡的曲线下面积为0.742,最佳截断值为13.95%,敏感度59.8%,特异性85.7%。低RDW患者的1年累积生存率显著高于高RDW患者(χ^(2)=18.757,P<0.001)。结论RDW是预测CA患者ICU住院期间死亡的独立危险因素。展开更多

Methods: The elderly patients with hip fracture who were treated in Xi’an Honghui Hospital from January 2015 to September 2019 were screened. The age, gender and other population characteristics of the patients were collected, as well as the injury mechanism, basic diseases at admission, fracture classification, RDW-CV, operation time, blood loss, infusion volume, blood transfusion volume, treatment strategy, hospitalization time, follow-up time and other clinical characteristics from admission time to operation. Multivariate Cox regression models were used to determine the relationship between RDW-CV and mortality in these patients. All analyses were performed using EmpowerStats and R software. Results: A total of 2303 patients were included in this retrospective cohort study and divided into three groups according to their RDW-CV levels. The average follow-up time was 39.23 months. The mean value of RDW-CV was 13.24 ± 0.48. The number of all-cause deaths after 1 year was 707 (30.69%). Multivariate Cox regression model showed that after excluding other influencing factors, RDW-CV was associated with mortality in elderly patients with hip fracture (hazard ratio = 1.13, 95% confidence interval: 1.07~1.18, P < 0.0001). When RDW-CV increased by 1%, the risk of death increased by 13%. Conclusion: The coefficient of variation of red blood cell volume size (RDW-CV) is associated with all-cause mortality in elderly patients with hip fracture, and RDW-CV can be considered as a predictor of death risk.展开更多
