Improved Performance of the Fourth-Generation FloTrac/Vigileo System for Tracking Cardiac Output Changes.
The aims of this study were to compare cardiac output (CO) measured by the new fourth-generation FloTrac™/Vigileo™ system (Version 4.00) (COFVS) with that measured by a pulmonary artery catheter (COREF), and to investigate the ability of COFVS to track CO changes induced by increased peripheral resistance. ⋯ The trending ability of the new fourth-generation FloTrac™/Vigileo™ system after increased vasomotor tone was greatly improved compared with previous versions; however, the discrepancy of the new system in CO measurement was not clinically acceptable, as in previous versions. For clinical application in critically ill patients, this vasomotor tone-dependent disagreement must be decreased.

Blood Conservation Strategies Can Be Applied Safely to High-Risk Complex Aortic Surgery.
The present study aimed to evaluate the effect of blood conservation strategies on patient outcomes after aortic surgery. ⋯ Clinical practice guidelines for blood conservation should be considered for high-risk complex aortic surgery patients.

In-hospital mortality in cardiac surgery patients after readmission to the intensive care unit: a single-center experience with 10,992 patients.
Determine if readmission to the intensive care unit (ICU) after cardiac surgery procedures is associated with increased mortality. ⋯ Patient readmission to the ICU following cardiac surgery was associated with a 5-fold increase in hospital mortality rate compared to non-readmitted patients. The highest mortality rate was observed among readmitted patients who underwent CABG. Older age, previous myocardial infarction, and initial long length of stay in the post-operative ward were independent risk factors for death after readmission to the ICU.
