             [摘    要 ]目的:探讨氧合指标及呼吸机参数在不同时间对急性呼吸窘迫综合征(acute respiratory distress syndrome,ARDS)临
              床转归的预测价值,筛选早期预后预警指标。方法:收集2017年 1 月至—2021 年6月南京医科大学附属儿童医院重症监护病
              房收治的65例ARDS患儿临床资料。依据治疗28 d后的存活状况分为存活组(n=37)和死亡组(n=28)。Logistic回归分析临床
              资料确定 ARDS 患儿死亡的高危因素。利用受试者工作特征曲线评估不同时间的氧合指标和呼吸机参数对 ARDS 患儿死亡
              风险的预测价值。结果:65例患儿中位年龄2.1岁。肺炎(60%)和脓毒症(24.6%)是引起ARDS的主要病因。对患儿基础疾病
              状态进行分析显示,有基础疾病患儿占60%,其中神经系统疾病占21.5%,血液病占16.9%,慢性肺疾病占6.2%,免疫缺陷病占
              7.7%。Logistic回归分析显示在机械通气的第0、1、3天动脉血氧分压与吸入氧浓度比值(PaO2/FiO2 )、脉氧饱和度与吸入氧浓度
              比值(SpO2/FiO2 )、氧合指数(OI)、氧饱和指数(OSI)、平均气道压(MAP)和呼气末正压(PEEP)均是ARDS的独立危险因素(P <
              0.05)。以上指标在机械通气第 3 天显示更好的预测价值(AUC:0.806~0.961)。结论:PaO2/FiO2、SpO2/FiO2、OI、OSI、MAP 和
              PEEP是ARDS患儿死亡独立危险因素,机械通气第3天各指标具有更好的预测价值。

             [Abstract] Objective:To investigate the predictive value of oxygenation parameters and ventilator parameters on the clinical
              outcome of acute respiratory distress syndrome(ARDS)at different times,and to screen early prognostic indicators. Methods:The
              clinical data of 65 children with ARDS admitted to the intensive care unit of Children’s Hospital of Nanjing Medical University from
              January 2017 to June 2021 were collected. According to the survival status after 28 days of treatment,they were divided into survival
              group(n=37)and death group(n=28). Logistic regression analysis of clinical data was to identify risk factors for death in ARDS
              patients. Receiver operating characteristic(ROC)curve was used to evaluate the predictive value of oxygenation parameters and
              ventilator parameters on mortality risk in children with ARDS at different times. Results:The median age of the 65 patients was 2.1
              years old. Pneumonia(60%)and sepsis(24.6%)were the main causes of ARDS. Analysis of the underlying disease status of patients
              showed that 60% of patients had underlying diseases,including neurological diseases(21.5%),hematological diseases(16.9%),and
              chronic lung diseases(6.2%)and immunodeficiency diseases(7.7%). Logistic regression analysis showed that PaO 2/FiO2,SpO2/FiO2,
              OI,OSI,MAP and PEEP were independent risk factors for ARDS on days 0,1 and 3 of mechanical ventilation(P < 0.05). The above
              indicators showed better predictive value on the 3rd day of mechanical ventilation(AUC:0.806~0.961). Conclusion:PaO2/FiO2,SpO2/
              FiO2,OI,OSI,MAP and PEEP are independent risk factors for death in children with ARDS,and each index has better predictive value
              on the third day of mechanical ventilation.
