Discontinuation of Cardiopulmonary Bypass

  • Luis G. Michelsen
  • Jack S. Shanewise


Discontinuation of cardiopulmonary bypass (CPB) is an obvious, necessary part of every operative procedure that includes extracorporeal circulation. This process removes the functions of blood flow and respiration from the heart-lung machine and returns them to the patient’s heart and lungs. To avoid mishap, it should be approached in a systematic, thorough manner. In this chapter, we will discuss the preparations for discontinuing bypass support and the mechanics of weaning a patient from CPB. We will then review cardiovascular pharmacologic support in the peri-CPB period, and management of the patient who cannot be readily weaned from CPB support.
