Abstract
Cardiac surgery patients may develop alterations of acid-base balance due to cardiac pathology, comorbidities, type and duration of surgery, and CPB. Acid-base status evaluation through ABG is the base for an adequate perioperative treatment. ABG interpretation needs more useful tool than those proposed by Henderson-Hasselbalch approach, such as anion gap, standard base excess, and strong ions difference, in order to identify the underlying acid-base disorders. In this chapter, the physiology and pathophysiology of acid-base balance in cardiac patients and their consequence on perioperative management are described; an overview on ABG interpretation and its relation with diagnostic hypothesis and therapeutic management are presented.
