Central Oxygen Venous Saturation and Mortality in Patients Undergoing Coronary Artery Bypass Grafting

Central venous oxygen saturation (ScvO ) has been reported as a prognostic marker of in-hospital mortality when it is below 60% in certain situations. Nevertheless, it has not been widely reported in patients undergoing coronary artery bypass graft (CABG). The study determined the association between ScvO and in-hospital mortality in patients undergoing CABG in a high-complexity health institution in Santiago de Cali, Colombia. A retrospective cohort study was conducted with patients undergoing isolated CABG. The subject sample included 515 subjects aged 18 years or older. Exposure was defined as ScvO 60 min), and intra-operative inotrope use. The primary cause of death was cardiogenic shock (54.7%), followed by sepsis (25.0%) and postoperative bleeding (17.2%). The study identified an association between ScvO
