Symposium 10:Treatment Strategies for Acute Respiratory Distress Syndrome due to Coronavirus Disease 2019
Acute respiratory distress syndrome (ARDS) is a severe pulmonary disease with high mortality. Besides the traditional protective lung ventilation strategy, recent treatment modalities have shown promising results. High-flow nasal cannula is employed in early ARDS due to Coronavirus disease 2019 (COVID-19). Besides the survival benefits in moderate to severe ARDS, prone positioning has been widely applied for COVID-19 patients, either intubated or non-intubated. Extracorporeal membrane oxygenation (ECMO) has also been used largely in patients with COVID-19 with acute respiratory distress syndrome during the pandemic. This symposium will discuss and summarize the evidence and recommendations about the three aforementioned treatment modalities for ARDS, especially due to COVID-19. The speakers will also share their clinical experiences in treating ARDS patietns.

High-flow nasal cannula for ARDS
Abstract:
The use of high-flow nasal cannula (HFNC) in adult patients with acute hypoxemic respiratory failure has continuously increased especially in COVID-19 pandemic. New category of non-intubated ARDS is created for patients on HFNC at ⩾30 L/min who otherwise meet ARDS criteria in a recently published global definition of ARDS. Recent research in ARDS gradually focused on the importance of identifying clinical and biological features subphenotypes in ARDS patients. Different subphenotypes might have different outcomes and response to specific therapies including HFNC. Here we will introduce and review the most recent improvement in application of HFNC to patients with ARDS.

Prone Positioning for ARDS
Abstract:
Acute Respiratory Distress Syndrome (ARDS) remains a significant challenge in critical care medicine, characterized by severe hypoxemia, diffuse pulmonary inflammation, and respiratory failure. Over the years, prone positioning has emerged as a promising intervention to improve oxygenation and outcomes in patients with ARDS.
Numerous studies and clinical trials have investigated the impact of prone positioning on ARDS outcomes. Meta-analyses of these trials consistently demonstrate significant improvements in oxygenation metrics, including PaO2/FiO2 ratio and oxygenation index, in patients placed in the prone position compared to those in the supine position. Furthermore, prone positioning has been associated with a reduction in mortality rates, although the magnitude of these benefits may vary depending on patient characteristics and the timing of prone sessions.
The physiological mechanisms underlying the efficacy of prone positioning are multifactorial and include more uniform ventilation-perfusion matching, reduced lung stress and strain, improved drainage of secretions, and attenuation of ventilator-induced lung injury. Additionally, recent evidence suggests that early initiation of prone positioning within the first 48 hours of ARDS onset may confer greater benefits compared to delayed prone positioning.
Despite its benefits, prone positioning is not without limitations and potential complications, such as pressure sores, endotracheal tube displacement, and hemodynamic instability. Careful patient selection, adequate sedation and paralysis, and meticulous positioning protocols are essential to mitigate these risks and optimize the effectiveness of prone positioning.
In conclusion, prone positioning represents a valuable adjunctive therapy in the management of ARDS, offering significant improvements in oxygenation, ventilation, and mortality outcomes. Early application, adherence to lung protective strategy, and longer duration (at least 16 hours/day) are keys to the successful management of ARDS with prone positioning.

Extracorporeal membrane oxygenation for ARDS
Abstract:
Extracorporeal membrane oxygenation (ECMO) has been widely used to provide respiratory and hemodynamic support to acute respiratory distress syndrome (ARDS) patients with severe hypoxemia. Recent studies have investigated the potential survival benefits of ECMO in patients with COVID-19 related ARDS and have shown that ECMO might be beneficial in some instances. However, ECMO is an invasive treatment with various complications that requires extensive monitoring and management. Indeed, the mortality of patients with COVID-19-associated ARDS managed with ECMO may be attribute to the involvement of experienced teams to decrease the rates of complications. This presentation aims to elucidate the associations between the use of ECMO and clinical outcomes of COVID-19 patients with ARDS.
