Central Venous Oxygen Saturation Cannot Replace Mixed Venous Saturation in Patients Undergoing Cardiac Surgery

Objective It has been argued that venous oxygen saturation from a central venous catheter (ScvO2 ) could be an inexpensive alternative to mixed venous oxygen saturation (SvO2 ). The aim was to evaluate whether ScvO2 measurements could replace SvO2 readings after cardiac surgery and to analyze factor...

Description
Summary:Objective It has been argued that venous oxygen saturation from a central venous catheter (ScvO2 ) could be an inexpensive alternative to mixed venous oxygen saturation (SvO2 ). The aim was to evaluate whether ScvO2 measurements could replace SvO2 readings after cardiac surgery and to analyze factors influencing any differences found. Design A prospective observational study. Setting A university hospital. Participants Twenty patients scheduled for elective cardiac surgery. Interventions Patients were followed postoperatively with corresponding ScvO2 /SvO2 measurements. Measurements and Main Results The overall bias between ScvO2 and SvO2 was 1.9. In coronary artery bypass graft (CABG) patients, the bias was 0.6 compared with 6.4 in procedures involving aortic valve replacement. In situations with peripheral saturation (SAT)
