Hypoxemic Acute Respiratory Failure

This observational study aims to assess the outcome and safety of O2-therapy by high-flow nasal cannula (HFNC) in 28 consecutive patients with severe hypoxemic acute respiratory failure (hARF) consequent to SARS-CoV-2 infection, unresponsive to conventional O2-therapy. Nineteen patients had a positive response. Nine patients required escalation of treatment to non-invasive ventilation (five subsequently intubated). None of the staff had a positive swab testing during the study period and the following 14 days. Severity of hypoxemia and C reactive protein level were correlated with HFNC failure. These data suggest HFNC to be a safe treatment for less severe patients with SARS-CoV-2 hARF and efficacy will need to be assessed as part of a clinical trial.

Background: Despite the increasing use of high flow nasal cannula oxygenation systems (HFNC) in clinical practice, little is known about its role in all cause respiratory failure as compared to traditional non-invasive ventilation (BiPAP). Furthermore, the effect of HFNC on mortality is unknown. Methods: We conducted a retrospective analysis of 49,853 patients with respiratory failure treated with non-invasive respiratory support (HFNC or BiPAP) and/or invasive mechanical ventilation (IMV) between 2017 and 2018. Results: Patients initially treated with HFNC who underwent subsequent intubation and IMV had a higher mortality rate as compared to patients who were initially treated with BiPAP and underwent subsequent intubation and IMV (34.8% vs 26.3%, p < 0.0001, OR 1.49, 95% CI 1.26,1.76). Patients first treated with HFNC who underwent subsequent intubation and IMV had a significantly increased mortality compared to patients who underwent immediate intubation and IMV (34.8% vs. 21.5%, p ≤ 0.0001, OR 1.94, 95% CI 1.67, 2.27). Stratified based on ICD-10 diagnosis, patients with a diagnosis of COPD exacerbation or heart failure treated with HFNC and subsequent intubation and IMV had higher mortality as compared to those treated with immediate IMV alone. This trend did not hold true for patients with a diagnosis of pneumonia. Conclusion: In a real-world retrospective analysis, use of HFNC was associated with increased mortality as compared to BiPAP and IMV alone. Further study is needed to confirm these associations.

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

Hypoxic Respiratory Failure

The novel corona virus (SARS-CoV-2) continuous to spread around the globe causing high mortality, tremendous stress on healthcare systems and an unprecedented disruption of everyday life with unpredictable socioeconomic ramifications. The diseaseis typically affecting the respiratory system and some patients will develop refractory hypoxemic respiratory insufficiency requiring mechanical ventilation. The role of non-invasive ventilation (NIV), high flow nasal cannula (HFNC) or continuous positive airway pressure devices (C-PAP) in the treatment of the 2019 corona virus disease (COVID-19) is not yet clear. We hereby report a case of a 44-year-old COVID-19 positive male patient suffering from hypoxic respiratory failure that was successfully treated with high flow nasal cannula oxygen therapy in a negative pressure intensive care room. Although specific criteria for the use of high flow nasal canula devices COVID-19 are not available at this time, clinicians could use this non-invasive modality as analternative method of respiratory support in selected patients presenting with respiratory failure.
