Abstract

Objective: This study aimed to analyze the characteristics of patients who fail high-flow nasal cannula(HFNC) therapy for acute hypoxemic respiratory failure(AHRF) and to identify predictors of treatment failure.

Methods: This single-center, retrospective, observational study analyzed clinical data from 388 patients with AHRF. Patients were divided into two groups: the HFNC success group (HFNC-S, n = 256) and the HFNC failure group (HFNC-F, n = 132). The primary endpoint was the need for escalation of respiratory support to tracheal intubation in the enrolled patients. The demographic data, laboratory tests, blood gas analysis data, CT severity scores, and disease severity scores were analysed to determine the difference between patients who were successful and those who failed HFNC treatment. Univariate and multivariate logistic regression models were used to assess potential predictors of failure of HFNC for patients with acute hypoxaemic respiratory failure.

Results: The mean age of patients enrolled was 67.97 ± 14.40 years. The HFNC-F group had significantly higher PSI(Pneumonia Severity Index) score, CURB(Confusion, Urea, Respiratory Rate, Blood Pressure, and Age)-65 score, CPIS(Clinical Pulmonary Infection Score) score, CT score and SOFA(Sequential Organ Failure Assessment) scores compared to the HFNC-S group. Within 12 h of the initiation of treatment, the HFNC-F group exhibited significantly lower oxygen saturation index (PaO2/FiO2) and significantly higher respiratory rate. Additionally, the HFNC-F group exhibited significantly higher levels of C-reactive protein (CRP), platelet count (PLT), D-dimer, interleukin-10 (IL-10), total bilirubin (TB) and creatinine (CB), but lower albumin levels. Multivariate analysis identified CT score, SOFA score, interleukin-1β (IL-1β), and albumin as independent predictors of HFNC failure.

Conclusion: HFNC is effective for treating AHRF. CT score, SOFA score, IL-1β, and albumin are independent predictors of HFNC failure.

一项预测急性缺氧性呼吸衰竭高流量氧疗失败的回顾性研究。

目的：本研究旨在分析高流量鼻插管（HFNC）治疗急性低氧性呼吸衰竭（AHRF）失败患者的特点，并探讨治疗失败的预测因素。方法：这项单中心、回顾性、观察性研究分析了388例AHRF患者的临床资料。患者分为两组：HFNC成功组（HFNC- s, n = 256）和HFNC失败组（HFNC- f, n = 132）。主要终点是纳入的患者需要呼吸支持升级到气管插管。分析人口统计学数据、实验室检查、血气分析数据、CT严重程度评分和疾病严重程度评分，以确定HFNC治疗成功和失败患者之间的差异。采用单因素和多因素logistic回归模型评估急性低氧性呼吸衰竭患者HFNC失败的潜在预测因素。结果：入组患者平均年龄67.97±14.40岁。与HFNC-S组相比，HFNC-F组的PSI（肺炎严重程度指数）评分、CURB（精神错乱、尿素、呼吸速率、血压和年龄）-65评分、CPIS（临床肺部感染评分）评分、CT评分和SOFA（序事性器官衰竭评估）评分均显著高于HFNC-S组。治疗开始后12 h内，HFNC-F组血氧饱和度指数（PaO2/FiO2）明显降低，呼吸速率明显升高。此外，HFNC-F组c反应蛋白（CRP）、血小板计数（PLT）、d -二聚体、白细胞介素-10 （IL-10）、总胆红素（TB）和肌酐（CB）水平显著升高，白蛋白水平显著降低。多因素分析发现，CT评分、SOFA评分、白细胞介素-1β (IL-1β)和白蛋白是HFNC失败的独立预测因子。结论：HFNC是治疗AHRF的有效方法。CT评分、SOFA评分、IL-1β和白蛋白是HFNC失败的独立预测因子。
