Fortunately, the same basic physiologic principles apply in both the healthy patient undergoing laparoscopic cholecystectomy as well as in the patient with low ejection fraction undergoing multiple valve replacements. Unfortunately, the patient undergoing cardiac surgery is more likely to decompensate severely when faced with the hemodynamic roller coaster sometimes associated with general anesthesia induction (Figure 2–1).
