Abstract Background Several randomized clinical trials have shown that non-invasive ventilation (NIV) applied immediately after extubation may prevent reintubation in patients at high-risk of extubation failure. However, most of studies included patients with chronic respiratory disorders as well as patients without underlying respiratory disease. To date, no study has shown decreased risk of reintubation with prophylactic NIV after extubation among patients with chronic obstructive pulmonary disease (COPD). We hypothesized that prophylactic NIV after extubation may decrease the risk of reintubation in COPD patients as compared with high-flow nasal oxygen. We performed a post hoc subgroup analysis of COPD patients included in a multicenter, randomized, controlled trial comparing prophylactic use of NIV alternating with high-flow nasal oxygen versus high-flow nasal oxygen alone immediately after extubation. Results Among the 651 patients included in the original study, 150 (23%) had underlying COPD including 86 patients treated with NIV alternating with high-flow nasal oxygen and 64 patients treated with high-flow nasal oxygen alone. The reintubation rate was 13% (11 out of 86 patients) with NIV and 27% (17 out of 64 patients) with high-flow nasal oxygen alone [difference, − 14% (95% CI − 27% to − 1%); p = 0.03]. Whereas reintubation rates were significantly lower with NIV than with high-flow nasal oxygen alone at 72 h and until ICU discharge, mortality in ICU did not differ between groups: 6% (5/86) with NIV vs. 9% (6/64) with high-flow nasal oxygen alone [difference − 4% (95% CI − 14% to 5%); p = 0.40]. Conclusions In COPD patients, prophylactic NIV alternating with high-flow nasal oxygen significantly decreased the risk of reintubation compared with high-flow nasal oxygen alone.

IntroductionA palliative approach to intensive care unit (ICU) patients with acute respiratory failure and a do-not-intubate order corresponds to a poorly evaluated target for non-invasive oxygenation treatments. Survival alone should not be the only target; it also matters to avoid discomfort and to restore the patient’s quality of life. We aim to conduct a prospective multicentre observational study to analyse clinical practices and their impact on outcomes of palliative high-flow nasal oxygen therapy (HFOT) and non-invasive ventilation (NIV) in ICU patients with do-not-intubate orders.Methods and analysisThis is an investigator-initiated, multicentre prospective observational cohort study comparing the three following strategies of oxygenation: HFOT alone, NIV alternating with HFOT and NIV alternating with standard oxygen in patients admitted in the ICU for acute respiratory failure with a do-not-intubate order. The primary outcome is the hospital survival within 14 days after ICU admission in patients weaned from NIV and HFOT. The sample size was estimated at a minimum of 330 patients divided into three groups according to the oxygenation strategy applied. The analysis takes into account confounding factors by modelling a propensity score.Ethics and disseminationThe study has been approved by the ethics committee and patients will be included after informed consent. The results will be submitted for publication in peer-reviewed journals.Trial registration numberNCT03673631

The objective: to evaluate the effect of high-flow oxygen and non-invasive ventilation on the mortality rate in adults with severe respiratory failure caused by the new coronavirus infection in the intensive care unit (ICU).Subjects and methods. A one-center retrospective study was conducted. Electronic medical files of patients treated in the ICU from April 1 to May 25, 2020, were analyzed. Totally, 101 medical files were selected, further, they were divided into two groups. Group 1 (n = 49) included patients who received oxygen insufflation, and should it fail, they received traditional artificial ventilation. No non-invasive respiratory therapy was used in this group. Group 2 (n = 52) included patients who received high-flow oxygen therapy and non-invasive ventilation. The mortality rate in the groups made a primary endpoint for assessing the impact of high-flow oxygen therapy and non-invasive ventilation. The following parameters were also analyzed: drug therapy, the number of patients in whom non-invasive techniques were used taking into account the frequency of cases when these techniques failed, and the number of patients in whom artificial ventilation was initiated.Results. In Group 2, non-invasive methods of respiratory therapy were used in 31 (60%) cases. High-flow oxygen therapy was used in 19 (36%) of them; in 13 cases this method allowed weaning them from the high flow. Non-invasive ventilation was used in 18 cases, in 12 patients it was used due to progressing severe respiratory failure during humidified oxygen insufflation, in 6 patients – after the failed high-flow oxygen therapy. In Group 1, 25 (51%) patients were intubated and transferred to artificial ventilation, in Group 2, 10 (19.2%) underwent the same. The lethal outcome was registered in 23 (47%) cases in Group 1, and in 10 (19.2%) in Group 2 (p = 0.004). Analysis of drug therapy in the groups revealed the difference in the prescription of pathogenetic therapy. Logistic regression demonstrated the effectiveness of the combination of tocilizumab + a glucocorticoid in reducing the frequency of lethal cases (p = 0.001).Conclusion. The use of non-invasive respiratory support in adults with severe respiratory failure caused by the new coronavirus infection combined with therapy by tocilizumab + a glucocorticoid can reduce the incidence of lethal cases.
