Abstract Introduction Despite recent interest in measurement of central venous oxygen saturation ScvO2 there are no published data describing the pattern of ScvO2 changes after major general surgery or any relationship with outcome. Methods ScvO2 and other biochemical physiological and demographic data were prospectively measured for 8 hours after major surgery. Complications and deaths occurring within 28 days of enrolment were included in the data analysis. Independent predictors of complications were identified with the use of logistic regression analysis. Optimum cutoffs for ScvO2 were identified by receiver operator characteristic analysis. Results Data from 118 patients was analysed 123 morbidity episodes occurred in 64 these patients. There were 12 deaths . The mean SD age was years. Twenty patients 17 underwent emergency surgery and 77 patients 66 were male. The mean SD P-POSSUM Portsmouth Physiologic and Operative Severity Score for the enUmeration of Mortality and morbidity score was with a predicted mortality of . After .
