Several Parameters of Extracorporeal Circulation and outcome

  • Allen E. Willner

The aim of cardiopulmonary bypass is the maintenance of peripheral gas exchange and nutrition by adequate tissue perfusion during open heart surgery. At first sight, the present low hospital mortality rate at least in elective cases - in our International Study 2% of 500 cases so far - seems to demonstrate that extracorporeal circulation generally meets this demand. However, according to authors like Wheatley [1], we have to question whether cardiopulmonary bypass guarantees a complete restoration of organ function after surgery.
