We present a 51-year-old man with cardiogenic shock in whom a percutaneous extracorporeal life support system (ECLS) was inserted to restore cardiopulmonary stability. After successful stabilization, a left ventricular assist device was implanted, using the ECLS without switching to a conventional cardiopulmonary bypass system to reduce its side effects.

A 20-year-old male was involved in a motor vehicle accident and computed tomography revealed a completely transected right mainstem bronchus. An Emergency Department (ED) right anterior thoracotomy was necessary soon after arrival at our institution secondary to acute desaturation that was unresponsive to ventilator and chest tube management. This allowed direct intubation and ventilation of the right middle and lower lobes directly through the thoracotomy incision, which stabilized the patient for transport to the operating room. ⋯ Post surgery, the patient was transported to the surgical intensive care unit on CPS which he required for an additional two days. The patient eventually did well and was discharged home. To our knowledge this is the first successful reported case of using the Avalon Elite dual lumen veno-venous cannula for CPS in a patient with complete right main-stem bronchus transection and bilateral pulmonary contusions.

Acute respiratory distress syndrome (ARDS) still represents a serious problem in clinical routine and is associated with a high mortality. Several concepts are known for special treatment, but, in some instances, the application of an extracorporeal membrane oxygenation (ECMO) is necessary for both the improvement of oxygenation and the elimination of carbon dioxide (CO(2)). ⋯ We report two outstanding cases of prone under conditions of a veno-venous ECMO therapy which improved significantly under this position. Furthermore, we reflect critically possible risk factors and adverse events of such procedures and afford a current view from the literature.

Randomized Controlled Trial
Beneficial effects of using a minimal extracorporeal circulation system during coronary artery bypass grafting.
In this study, we assessed clinical results by using a minimal extracorporeal circuit (MECC) and compared it to a conventional cardiopulmonary bypass (CPB) system in patients undergoing coronary artery bypass grafting (CABG) procedures. ⋯ In conclusion, the MECC system is a safe alternative for patients who undertake extracorporeal circulation (ECC) for CABG surgery. Lower transfusion requirements and less damage to red cells may further promote the use of MECC systems, especially in higher risk patients.

Randomized Controlled Trial
Milrinone, a phosphodiesterase III inhibitor, prevents reduction of jugular bulb saturation during rewarming from hypothermic cardiopulmonary bypass.
Inadequate cerebral oxygen balance during cardiopulmonary bypass may cause neuropsychological dysfunction. Milrinone, a phosphodiesterase III inhibitor, augments cerebral blood flow by direct vasodilatation. We conducted a prospective, randomized study in patients undergoing cardiac surgery with cardiopulmonary bypass to clarify the clinical efficacy of milrinone in the imbalance of cerebral oxygen supply and demand during the rewarming period of cardiopulmonary bypass. ⋯ Milrinone suppresses the reduction of SjO(2) and improves the balance of cerebral oxygen supply and demand during the early rewarming period of hypothermic cardiopulmonary bypass.
