摘要: Optimising perioperative haemodynamic status may reduce postoperative complications. In this prospective prevalence study, we investigated the associations between standard parameters and a low central venous oxygen saturation (ScvO2) in patients after major surgery. A total of 201 requiring continuous arterial pressure monitoring surgery were recruited. Simultaneous blood gases, biochemical data perfusion index obtained from at single time-point within 24 hours ScvO2 (<70%) was observed 109 (54%). Use mechanical ventilation, mean pressure, haemoglobin concentrations, pH lactate (PaO2) carbon dioxide tensions (PaCO2) all associated with univariate analyses. multivariate analysis, only higher (odds ratio [OR] 0.87, 95% confidence interval [CI] 0.78 to 0.98), PaO2 (OR 0.98 per mmHg increment, CI 0.97 0.99) PaCO2 0.88 0.82 0.95) lower 1.14 1.04 1.25) significantly reduced risk ScvO2, linear fashion. conclusion, PaO2, PaCO2, significant predictors including cardiac
