Study of Mixed Venous Oxygen Saturation (SVO2) Measurement in High-Risk Cardiac Surgical Patients

Abstract

Background: Postoperative haemodynamic complications are the leading cause of mortality in heart surgery. Early prediction of postoperative complications based on haemodynamic parameters is invaluable for timely intervention, and can influence the operative outcome. In developed countries, the use of Swan-Ganz catheter to monitor patients’ postoperative haemodynamic variables for predicting short-term risks has become a gold standard. In Vietnam, there are hundreds cases of cardiac surgery each year; however, there has been no report on monitoring patients’ haemodynamic state and its predictive power for short-term operative outcomes. This study reported using mixed venous oxygen saturation (SVO2) as a prognostic marker for short-term outcome in high-risk cardiac surgical patients at hospitals in Vietnam from 2013–2015.
