“…In the present study the ScvO 2 value, though it has been proposed as an alternative variable to SvO 2 in the critically ill (39), did not differ significantly between patients with and without prolonged ICU stay. However, this finding is not surprising because the accuracy of ScvO 2 to predict SvO 2 among patients undergoing cardiac surgery is unreliable (40).…”

Background The outcome of cardiogenic shock complicating myocardial infarction has not appreciably changed in the last 30 years despite the development of various percutaneous mechanical circulatory support options. It is clear that there are varying degrees of cardiogenic shock but there is no robust classification scheme to categorize this disease state. Methods A multidisciplinary group of experts convened by the Society for Cardiovascular Angiography and Interventions was assembled to derive a proposed classification schema for cardiogenic shock. Representatives from cardiology (interventional, advanced heart failure, noninvasive), emergency medicine, critical care, and cardiac nursing all collaborated to develop the proposed schema. Results A system describing stages of cardiogenic shock from A to E was developed. Stage A is “at risk” for cardiogenic shock, stage B is “beginning” shock, stage C is “classic” cardiogenic shock, stage D is “deteriorating”, and E is “extremis”. The difference between stages B and C is the presence of hypoperfusion which is present in stages C and higher. Stage D implies that the initial set of interventions chosen have not restored stability and adequate perfusion despite at least 30 minutes of observation and stage E is the patient in extremis, highly unstable, often with cardiovascular collapse. Conclusion This proposed classification system is simple, clinically applicable across the care spectrum from pre‐hospital providers to intensive care staff but will require future validation studies to assess its utility and potential prognostic implications.

“…This main shortcoming comes from the fact that CO distribution changes in critically ill patients, thus affecting ScvO 2 and SvO 2 relationships [14][15][16][17] . Unlike previous, studies performed under experimentally controlled conditions found good correlation between ScvO 2 and SvO 2 , regardless of their absolute values 18,19 .…”

Correlation between central venous and mixed venous oxygen saturation in the elective abdominal aortic aneurysm surgery

Background/Aim. The concept of utilizing central venous oxygen saturation (ScvO2) to calculate cardiac index (CI) remains controversial and neither precise nor generally applicable conclusion has been reached yet. We evaluated the relationship between ScvO2 and mixed venous oxygen saturation (SvO2) in elective surgery of the abdominal aorta. The adequacy of their interchangeability was tested by comparing cardiac indices (CI) calculated by two methods in patients that underwent major vascular surgery. The aim of this study was to test the correlation between ScvO2 and SvO2 in different time frames, in patients undergoing elective abdominal aortic aneurysm (AAA) surgery as well as to determine if the use of ScvO2 for calculating CI by the modified Fick equation, could be feasible and accurate surrogate for the values obtained by pulmonary artery catheter (PAC). Methods. This prospective observational study included 125 consecutive patients that underwent elective AAA surgery. The ScvO2 and SvO2 data, as well as CI values, were obtained and compared from samples taken in three different time frames: immediately after induction of general anesthesia (T0), immediately after admission in the intensive care unit (ICU; T1), and 8 h after admission in the ICU (T2). The Fick equation, used for CI estimation from ScvO2 (CI-F), for the purpose of this study, was simplified according to Walley. Results. There was good linear correlation between ScvO2 and SvO2 in all time frames and linear regression study revealed strongest coefficient of determination (R2 = 0.661) in T2 time-frame. There was no correlation between CI-F (i.e. CI calculated from ScvO2 by modified Fick equation) and CI (measured by PAC from SvO2) in any time-frame. Conclusion. The results of our study confirm that ScvO2 is a reliable substitute for SvO2 among patients undergoing elective surgery of the AAA. However, ScvO2 cannot be used as a surrogate to true SvO2 in the calculation of CI.
