Extracorporeal lung support for advanced lung failure: a new era in thoracic surgery and translational science.

For the patients with progressively decompensating acute or acute-on-chronic respiratory failure, the first-choice treatment remains as mechanical ventilation. Despite the consistent value of mechanical ventilation, the majority of lung specialists are aware of its limitations, in particular for the patients with advanced lung failure, and inherent drawbacks that augment disease progression. More recently, the concept of allowing the lungs to ‘rest and recover’ has been supported by quite a few clinical studies. The pressure and volume of gas delivered to the lungs are reduced compared with mechanical ventilation. Based on recent remarkable evidence and experiences using extracorporeal lung support (ECLS) before, during and after lung transplant, there is growing interest in and expectations for the use of ECLS beyond lung transplant to encompass the entire field of pulmonary medicine. The purpose of this review article is to provide an update on evolving ECLS technologies and their effectiveness and discuss the future of ECLS for advanced lung failure as a new subspecialty in cardiothoracic surgery.
