ABSTRACT
@#Extracorporeal membrane oxygenation (ECMO), as an extracorporeal life support technology, can provide respiratory support and hemodynamic support according to different modes. The significant advantages of ECMO in the treatment of acute respiratory distress syndrome and the development of its oxygenator, pump, and heparin-coated circuits have promoted its application and exploration in thoracic surgery. ECMO can be used during the perioperative period of lung transplantation and can be applied for patients who cannot maintain one-lung ventilation, or have a high risk of anesthesia, or undergo complex thoracic surgery involving trachea, carina, mediastinum and esophagus. This article will review the application and progress of ECMO in general thoracic surgery.
ABSTRACT
Objective To investigate the effects of extracorporeal membrane oxygenation (ECMO) in severe cardiopaths with crisis. Methods Fourteen cases of severe eardiopaths with crisis were treated by ECMO with V A- ECMO technique, whose pump was centrifugal pump and whose tubes was spread byheparin. The cases included 8 fulminating myocarditis (FM) cases with ventricular arrhythmias or/and acute heart failure or/and cardiac shock and 6 acute myocardial infarction cases with pump failure or cardiac shock,in whom 10 cases with cardiorespiratory resuscitation. Haemodynamics and blood gas analysis, and so on were measured before and after treatment. Results The support time of ECMO was 3-106 h, mean (32.4±27.6) h. After ECMO mean arterial blood pressure (MAP), left ventricular ejection fraction (LVEF), left ventricular end-diastolic dimension (LVEDd), partial pressure of arterial oxygen, saturation of blood oxygen improved (P < 0.05 or < 0.01 ), negative value of base excess decreased significantly( P < 0.01 ). MAP had notchanged before and after stopping ECMO [ (80.02±10.20) wan Hg (1 mm Hg = 0.133 kPa) vs (76.34±9.15) mm Hg] (P > 0.05), however, LVEF and LVEDd improved continually (P <0.05). Conclusion ECMO can provide oxygen supply and stable circulation volume for severe cardiopaths with crisis to recover cardiorespiratory function or save valuable time to treat primary disease.
