Risk factors for in-hospital mortality after coronary artery bypass grafting in Colombia

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

“…12 Recently, a case-control study was conducted in the city of Cali, Colombia, to identify factors associated with intrahospital mortality following CABG and revealed a significant association between postoperative variables, such as cardiogenic shock, use of vasopressors, tracheal reintubation, surgical site infection, mediastinitis and AKI with dialysis, and ScvO 2 <60% upon admission into the intensive care unit (ICU). 13 These studies concur that a factor, such as ScvO2, is a good predictor of mortality in individuals undergoing coronary bypass surgery. However, as we conducted in this study, only one of these investigations achieved ScvO2 <60% as a cut-off point.…”

“… 10 Likewise, Lozada et al recently conducted a case–control study and showed the factors associated with intrahospital mortality following CABG; among other variables, a significant connection to SvO 2 <60% upon ICU admission was reported. 13 In this sense, it is important to understand that ScvO2 is determined by changes in oxygen supply and consumption, which is associated with the physiopathological features of shock states. As a result, its levels should be monitored in high-risk patients following surgery to reverse the triggering causes of tissue hypoxia and prevent morbimortality.…”
