Abstract: (556 Views)
Background & Objectives: Acid–base abnormalities are common in critically ill patients. Our ability to describe acid–base disorders must be precise. The aim of this study to investigate the incidence and type of perioperative metabolic disturbances and electrolyte abnormality in patients undergoing coronary artery bypass graft surgery.
Materials & Methods: This was a prospective, observational study, performed in a university-affiliated hospital. 62 patients undergoing coronary artery bypass graft surgery were included in the study. After operation the patients were transferred to cardiac intensive care unit and electrolytes and acid-base variables were recorded. The primary endpoint of the study was the incidence of metabolic alkalemia or acidemia. Metabolic alkalemia was defined as PH >7.45 and BE >+3. Metabolic acidemia was defined as PH <7.35 and BE <-3.
Results: From 62 patients 34 (54.8 %) had normal acid base analysis. Respiratory alkalosis, metabolic acidosis and alkalosis were occurred in 20 (32.3), 6 (9.7 %) and 2 (3.2) of subjects respectively. Respiratory acidosis is not seen.
Conclusion: Regardless of normal subjects, respiratory alkalosis occurred more frequently than other acid base disorders in patients after coronary artery bypass graft surgery.
