About
HFNO and NIV strategies are the most commonly used strategies for the treatment of hypoxia in patients with a diagnosis of COVID-19 who are still followed in the intensive care unit, but there is no study comparing the two yet. In our prospective study, we aimed to compare these two treatment modalities. The primary goal is that the treatment is successful (weaned off HFNO/weaned off NIV: No need for HFNO or NIV and the patient recovers without the need for intubation). Failure will be evaluated as the need for intubation during treatment or the patient's death. Secondary aim is failure of treatment and discharge of patients from intensive care to service or home.
Full description
Coronavirus 2019 disease (COVID-19) is a deadly infection that causes a new type of severe acute respiratory syndrome. It has been reported that the mortality rate in critically ill patients with a diagnosis of COVID-19 reached 61%. The primary pathology in these patients is progressive hypoxia due to lung injury and associated multi-organ damage. It has been reported that aggressive treatments such as tracheal intubation and classical mechanical ventilation to treat lung injury are not helpful or even harmful. The highest mortality rate was reported as 86% in these patients on mechanical ventilation. Acute respiratory distress syndrome (ARDS) developing in COVID-19 infection is not typical and is estimated to have a different mechanism, therefore it is emphasized that different strategies should be used for the treatment of ARDS in these patients. Two of the most important strategies used in these patients followed in the intensive care unit are high flow nasal oxygenation (High Flow Nasal Oxygenation-HFNO) and non-invasive ventilation (Non-Invasive Ventilation-NIV). HFNO is a method frequently used before intubation in adult patients with acute respiratory failure. It is based on the principle of giving warm and humidified oxygen to the patient through a nasal cannula in the range of 1-70 L/min. Due to the low number of mechanical ventilators in many intensive care units at the beginning of the pandemic, it was used in many COVID-19 patients and was found to be effective in later retrospective analyzes. It has been reported in many studies that HFNO therapy is more effective than conventional mask oxygen therapy. There are publications stating that it is more advantageous compared to NIV as it is easier to apply and more comfortable for the patient. Conventional NIV is called continuous positive airway pressure (CPAP) or Bi-level positive airway pressure (BiPAP) ventilation. It is used as oxygen/ventilation therapy in SARS and H1N1 patients. Studies have reported that it is used in 70% of patients before tracheal intubation in COVID-19 patients. However, mortality was high in these patients.
