Anesthesia for Coronary Artery Bypass Grafting with and Without Cardiopulmonary Bypass
The most common cardiac surgical procedure performed in the United States is coronary artery bypass grafting (National Heart Lung and Blood Institute, https://www.nhlbi.nih.gov/health/health-topics/topics/hs/types, 2017). However, between 2008 and 2012 the number of bypass surgeries has decreased and the average patient presents with more comorbidities than in the past. Fortunately, the in-hospital mortality rate has decreased from 2.7 to 2.2% over the same period (Moazzami et al., J Cardiothorac Vasc Anesth 31:19, 2017). The anesthetic requirements for coronary bypass vary with surgical approach, need for cardiopulmonary bypass (CPB), and other patient-specific factors. Both on-pump (CABG) and off-pump coronary artery bypass (OPCAB) will be discussed in this chapter. A separate section in this text discusses minimally invasive techniques such as robotic CABG.
