Abstract

Objectives: to evaluate several successful predicting scales when applying humidified high flow nasal canula after extubation in patients with acute exacerbation of chronic obstructive pulmonary disease. Method: A prospective interventional study, all patients eligible for the study was chosen. The patient was applied HFNC immediately after extubation. Clinical indicators and blood gases after extubation were collected. Success of HFNC defined as the patient did not require reintubation or noninvasive ventilation within 48 hours of extubation. The study was conducted from May 2022 to June 2023 at the Center for Critical Care Medicine - Bach Mai Hospital. Results: There were 31 patients participating in the study. In which, there were 28 male patients (90.3%), 3 female patients (9.7%). The mean age was 70.58±9.319 years old, the oldest was 84 years old, the youngest was 49 years old. Most common comorbidities were hypertension (25.8%) and heart failure (22.8%). The success rate was 77.42%. The predictive value of success when applying the HFNC system based on the ROX scale at the time of T_0.5 had a cutoff point of 11.49 with a sensitivity of 66.7% and a specificity of 71.4%. In addition, the HACOR scale at the time of T_0.5 had a cutoff of 2.5 with a sensitivity of 57.1% and a specificity of 83.3%. Conclusions: ROX and HACOR scale have predicting value when applying the HFNC system on patients with COPD exacerbations after extubation.
