Diagnostic accuracy of central venous saturation in estimating mixed venous saturation is proportional to cardiac performance among cardiac surgical patients

摘要: Abstract Purpose Advanced hemodynamic monitoring in cardiac surgery translates into improvement outcomes. We evaluated the relationship between central venous (ScvO 2 ) and mixed (SvO saturations over early postoperative period. The adequacy of their interchangeability was tested patients with varying degrees performance. Methods In this prospective observational study, we 156 consecutive surgical an academic center. ScvO SvO data were harvested from 468 paired samples taken preoperatively (T0), after weaning cardiopulmonary bypass (T1) on day 1 (T2). Results inconsistent, inferior correlations lower indices (CI) (Pearson r = 0.37 if CI ≤2.0 L/min per square meter vs 0.73 >2.0 meter, both P . proportion a negative -ScvO gradient increased time (48/156 [31%] at T0 to 73/156 [47%] T2; (odds ratio, 6.46 [95% confidence interval, 0.81-51.87], .06) also had higher serum lactate levels (1.5 ± 0.8 1.0 0.4; Conclusions diagnostic accuracy for estimating is proportional A T2 correlated inotropic support requirement, operative risk score, age, level, duration bypass.
