Peyrony O, et al. - In patients with cancer presenting to the emergency department, researchers explored the link between central venous oxygen saturation (ScvO₂) and early complications. They prospectively enrolled adult patients with cancer and pre-existing central venous catheters (CVC) who presented to the ED. A shock-index of > 1 and a performance status of > 2 were the included variables that were related to intensive care unit admission or death by day 7. Findings did not support the use of ScvO₂ to risk stratify cancer patients presenting to the ED.
