The Optimal Cell Salvage Settings to Maximize Hematocrit and Minimize Potassium Using the Cobe BRAT2 Autologous Blood Recovery Unit.
The objective was to determine the optimal cell saver device settings (infusion rate and wash rate) at which hematocrit is preserved and potassium and lactate are removed from banked red blood cells (RBC). ⋯ Red-cell washing produces higher hematocrit and lower potassium as infusion rate and wash rate decrease. A 340-mL unit of RBC can be processed in 4.26 minutes without loss of hematocrit or an increase in potassium when both infusion and wash rates are set to 400 mL/min.

Observational StudyOne-Year Outcome After Cardiac Surgery for Patients With Cancer: An Observational Monocentric Retrospective Study.
Cardiac surgery increasingly is being performed in patients with a history of or with active cancer. The aim of this study was to analyze the association between a history of cancer and 1-year mortality after cardiac surgery with cardiopulmonary bypass (CPB). ⋯ In a large cohort of patients undergoing cardiac surgery with CPB, cancer was not independently associated with 1-year mortality. An isolated cancer history should not lead to denial of cardiac surgery. The impact of cancer on complications and long-term survival after cardiac surgery requires further research.

Observational StudyAccuracy, Precision, and Trending Ability of Perioperative Central Venous Oxygen Saturation Compared to Mixed Venous Oxygen Saturation in Unselected Cardiac Surgical Patients.
To determine whether central venous oxygen saturation (ScvO2) measurements could be used interchangeably with mixed venous oxygen saturation (SvO2) measurements in adult cardiac surgery patients. ⋯ ScvO2 values showed acceptable accuracy as the mean bias was low. The precision was inadequate; although the PE was acceptable, the LOA were wide. Trending ability was inadequate. The authors cannot recommend the use of ScvO2 values interchangeably with SvO2 measurements in the management of adult cardiac surgery patients.
