Key result
Guiding fluid and inotrope therapy with ScvO2 and venous-arterial CO2 difference may optimize tissue oxygenation.
Why the study?
Adequacy of oxygen delivery to meet tissue oxygen metabolic demand during the perioperative period is essential to prevent tissue hypoxia and organ dysfunction, but optimal thresholds and parameters to guide fluid therapy remain unclear.
Does the complementary use of ScvO2 and P(cv-a)CO2 guide fluid therapy and inotropic support to prevent tissue hypoxia in the perioperative period?
Does the complementary use of ScvO2 and P(cv-a)CO2 guide fluid therapy and inotropic support to prevent tissue hypoxia in the perioperative period?
The complementary use of ScvO2 and P(cv-a)CO2 may provide a more accurate assessment of tissue oxygenation to guide perioperative fluid and inotropic therapy.
No takes yet. Share an insight, caveat, or question.
Should not yet change perioperative fluid or inotrope decisions; leaves open prospective validation of combined ScvO2-P(cv-a)CO2 targets.
Vallet et al. (2010) conducted a review in Perioperative tissue hypoxia. Tissue oxygenation parameters (ScvO2 and P(cv-a)CO2) guided fluid therapy was evaluated. Guiding fluid therapy and inotropic support using a combination of central venous oxygen saturation and central venous-to-arterial carbon dioxide difference may help optimize tissue oxygenation.
