The Role of Extracorporeal Membrane Oxygenation in Severe Acute Respiratory Distress Syndrome (ARDS): A Comprehensive Review of Current Evidence and Future Directions.

Severe acute respiratory distress syndrome (ARDS) is a life-threatening condition characterized by refractory hypoxemia and high mortality, particularly in cases unresponsive to conventional therapies. Extracorporeal membrane oxygenation (ECMO) has emerged as a critical rescue modality, providing temporary support for oxygenation and ventilation while mitigating ventilator-induced lung injury. This comprehensive review evaluates the current role of ECMO in managing severe ARDS, focusing on its indications, patient selection criteria, and the evolution of ECMO technologies. A detailed analysis of pivotal clinical trials and observational studies is presented, highlighting the evidence supporting its efficacy and safety. Key complications associated with ECMO, including bleeding, thrombosis, and infections, are discussed, along with strategies to minimize these risks. Despite advances, the optimal timing of ECMO initiation and the long-term outcomes of patients remain areas of ongoing research. Emerging innovations, such as portable ECMO systems and integration with advanced imaging modalities, have the potential to expand their applicability and improve patient outcomes. Furthermore, this review outlines the implications of recent guideline updates and expert consensus for standardizing ECMO practices globally. By synthesizing current evidence, this study underscores the evolving role of ECMO in ARDS management and identifies future research priorities to refine its use in clinical practice, ultimately aiming to improve survival and quality of life for patients with severe ARDS.
