摘　　要：目的分析非心脏术后低氧性呼衰患者接受经鼻高流量氧疗(HFNC)治疗失败的早期危险因素。方法回顾分析北京大学人民医院2016年1月至2019年12月接受HFNC治疗并符合标准的患者资料,探索HFNC失败的心脏及非心脏危险因素并建立早期预警模型。结果共纳入患者133例,根据HFNC失败标准分为HFNC失败组(n=40)和成功组(n=93)。多因素分析显示,治疗初期高急性生理与慢性健康状况评分Ⅱ(APACHⅡ)、发热、高心肌肌钙蛋白I(TNI)及治疗1 h后ROX(SpO_2/FiO_2/RR)<8是HFNC失败的独立危险因素;建立回归模型Y=-2.158+1.882×发热+0.283×APACHII-0.326×ROX+2.222×TNI,模型ROC曲线下面积(AUC)为0.915。结论非心脏术后低氧性呼衰患者应用HFNC,基础高APACHⅡ评分及TNI、发热,提示治疗失败风险较高,应谨慎选择,治疗1 h后ROX仍较低,应及时调整治疗策略。Objective To investigate the risk factors associated with failure of nasal high-flow nasal oxygen therapy(HFNC)in hypoxic respiratory failure patients after non-cardiac surgery.Methods This retrospective study was conducted at Peking University People′s Hospital.The subjects included all patients who suffering hypoxic respiratory failure after non-cardiac surgery from January 2016 to December 2019.Clinical and laboratory parameters use statistical methods to explore the risk factors involved in HFNC failure and establish an early warning model.Results A total of 133 patients were included.According to HFNC failure criteria,patients were divided into HFNC failure group(n=40)and success group(n=93).Multivariate analysis showed that patient with temperature(T)>37.3℃,high acute physiology and chronic health status scoreⅡ(APACHⅡ)score,cardiac troponinⅠ(TNI)level before using HFNC,and low ROX(SpO2/FiO2/RR)<8 at 1 hour after treatment were independent risk factors for HFNC failure;a regression model was established:Y=-2.158+1.882×fever+0.283×APACHⅡ-0.326×ROX+2.222×TNI,the area under the ROC curve(AUC)of the model is 0.915(P<0.01).Conclusions Hypoxic respiratory failure patients after non-cardiac surgery fever,High APACHII score and TNI level at baseline are indicate a higher risk of HFNC failure.ROX is still lower after 1 h treatment an important indicator for further mechanical ventilation,the treatment strategy should be adjusted in time.
