Extracorporeal membrane oxygenation for general thoracic surgery: case series and narrative review.

ABSTRACT

Background and Objective: Extracorporeal membrane oxygenation (ECMO) has historically been utilized as a temporary life support option for patients with severe cardiac and pulmonary dysfunction. Recent advancements have enabled the safe application of ECMO in a wider variety of patients; we present a review of its use in patients undergoing general thoracic procedures supported by a case series at our institution. Methods: We review current literature focusing on ECMO applications in thoracic surgery outside of the traditional use. Additionally, we offer three cases of ECMO utilization to illustrate success stories and key lessons learned regarding the use of ECMO in general thoracic surgery. Key Content and Findings: Technologic advancements and enhanced safety profiles have enabled the safe application of ECMO in a wide array of patients far beyond the historic indications of cardiogenic shock and acute respiratory distress syndrome (ARDS). It is now feasible to consider ECMO for management of acute thoracic emergencies, as well as to better facilitate operative safety in complex general thoracic surgical procedures. Both venovenous and venoarterial ECMO can be utilized in carefully selected patients to provide cardiopulmonary support while enabling improved visualization and increased mobilization without concern for respiratory and/or cardiac compromise. Conclusions: Enthusiasm for the use of ECMO has increased in recent years. What was once considered a salvage therapy in cases of life-threatening cardiopulmonary decompensation now plays an increasingly important role in the safe conduct of complex thoracic surgery procedures, provides much needed time for organ recovery, and offers acute resuscitation options. This shift broadens our ability to deliver life-saving care to patients that previously would have otherwise had limited treatment options.
