Excerpt
Monitoring of oxygen saturation in the superior vena cava (ScvO
2) was suggested as a simpler and cheaper assessment of the global DO
2:VO
2 ratio and was used successfully as a goal in treatment of patients with septic shock and severe sepsis [
1]. In patients with low cardiac output (CO) the difference between SvO
2 and ScvO
2 is more expressed and problematically large confidence limits and poor correlation were found between the two values [
2]. The thenar muscle oxygen saturation (StO
2) measured with near-infrared spectroscopy (NIRS) during stagnant ischemia (cuff inflation-induced vascular occlusion) decreases slower in septic shock patients [
3]. This may be due to slower muscle tissue oxygen consumption in sepsis. This phenomenon possibly contributes to the ScvO
2–SvO
2 mismatch in patients with low CO by adding more oxygenated venous blood to flow through the superior vena cava. The aim of present study was to determine the relationship between the StO
2 deceleration rate and the ScvO
2–SvO
2 difference in septic patients with low CO. …
