Extracorporeal life support during lung transplantation

Area of Science:

• Cardiovascular Surgery
• Thoracic Surgery
• Transplantation Medicine

Background:

• Lung transplantation is often performed off-pump.
• Extracorporeal life support (ECLS) may be necessary for hypoxemia or hemodynamic instability during surgery.
• Cardiopulmonary bypass (CPB) is the traditional ECLS method but carries risks like bleeding and primary graft dysfunction.

Purpose of the Study:

• To critically examine the advantages and disadvantages of off-pump lung transplantation.
• To compare the use of extracorporeal membrane oxygenation (ECMO) versus CPB for ECLS during lung transplantation.
• To highlight the need for further research comparing CPB and ECMO in lung transplantation.

Main Methods:

• Review of current literature on lung transplantation techniques.
• Analysis of the pros and cons of off-pump, CPB-assisted, and ECMO-assisted lung transplantation.
• Examination of existing comparative studies on CPB and ECMO in lung transplantation.

Main Results:

• Off-pump lung transplantation avoids CPB-related complications.
• ECMO offers flexibility in bridging to transplantation and postoperative recovery.
• CPB is associated with increased bleeding, transfusion needs, and prolonged intubation.
• Comparisons between CPB and ECMO are limited, necessitating further investigation.

Conclusions:

• Both CPB and ECMO have distinct advantages and disadvantages for ECLS in lung transplantation.
• The choice between CPB and ECMO depends on patient-specific factors and institutional expertise.
• More robust comparative studies are required to establish the optimal ECLS strategy for lung transplantation.
