“…(2,3) However, studies have demonstrated that there is a good correlation between SvcO 2 and SvO 2 and that they vary in parallel. (7-9) Compared to SvO 2 , therefore, the use of SvcO 2 is a faster and more practical alternative in tissue hypoperfusion monitoring.…”

“…(12-16) Moreover, in some cases, puncture of the internal jugular or subclavian vein may not be possible or may even be risky, leaving deep femoral vein access as the only alternative. (2,17) On several occasions, we have observed the clinical use of such parameters as surrogate values for central venous pressure (CVP) and SvcO 2 . Although a few studies have demonstrate that in the absence of intra-abdominal hypertension, venous pressure measured in catheters in the femoral vein correlate well with CVP, (17) the use of the femoral vein for monitoring venous pressure and obtaining blood samples to verify venous saturation remains controversial.…”

The use of central venous oxygen saturation (SvcO2) and arterial lactate in the diagnosis of severe tissue hypoperfusion is well established, and the optimization of these parameters is currently under investigation, particularly in patients with severe sepsis/septic shock. However, the only place for deep venous puncture or the first choice for puncture is often the femoral vein. Although venous saturation obtained from blood sampling from this catheter, instead of SvcO2, has already been used in the diagnosis of severe tissue hypoperfusion, little is known about the accuracy of the results. The venous lactate in place of arterial puncture has also been used to guide therapeutic decisions. We conducted this literature review to seek evidence on the correlation and concordance of parameters obtained by collecting femoral venous blood gases in relation to SvcO2 and arterial lactate. Few studies in the literature have evaluated the use of femoral venous oxygen saturation (SvfO2) or venous lactate. The results obtained thus far demonstrate no adequate agreement between SvfO2 and SvcO2, which limits the clinical use of SvfO2. However, the apparent strong correlation between arterial and peripheral and central venous lactate values suggests that venous lactate obtained from the femoral vein could eventually be used instead of arterial lactate, although there is insufficient evidence on which to base this procedure at this time.

critical illness and comorbid conditions. Without these changes in place, we will remain in the dark ages with respect to universal guideline application. Failure to create these systems will lead to a plethora of unobtainable guidelines that do not benefit our patients. We strongly urge clinicians and information specialists to work toward this essential and important goal to improve patient care and bring evidence-based guidelines to the bedside.
