Predicting Fluid Responsiveness During Infrarenal Aortic Cross-Clamping in Pigs.
Infrarenal aortic cross-clamping (ACC) induces hemodynamic disturbances that may affect respiratory-induced variations in stroke volume and, therefore, affect the ability of dynamic parameters such as pulse-pressure variation (PPV) to predict fluid responsiveness. Since this issue has not been investigated yet to authors' knowledge, the hypothesis was tested that ACC may change PPV and impair its ability to predict fluid responsiveness. ⋯ ACC induced a significant increase in PPV and reduced its ability to predict fluid responsiveness.

Observational StudyIncorporating Oliguria Into the Diagnostic Criteria for Acute Kidney Injury After On-Pump Cardiac Surgery: Impact on Incidence and Outcomes.
Consensus definitions represent an important step toward defining the epidemiology of acute kidney injury (AKI). However, the oliguric component of these definitions remains of uncertain impact and utility after cardiac surgery. The authors sought to define the specific impact of oliguric criteria, both alone and in combination with serum creatinine criteria, on the observed incidence of AKI and associated adverse outcomes following adult cardiac surgery. ⋯ Acute Kidney Injury Network oliguric criteria applied over 48 hours after surgery dramatically increased the measured incidence of AKI after cardiac surgery, but was not associated with adverse outcomes.

Comparative StudySystematic Error of Cardiac Output Measured by Bolus Thermodilution With a Pulmonary Artery Catheter Compared With That Measured by an Aortic Flow Probe in a Pig Model.
The precision of thermodilution cardiac output measurement using a pulmonary artery catheter can be divided into random and systematic errors. This study determined the systematic component. ⋯ Thermodilution does trend cardiac output reliably in most cases. However, the systematic error is large and has a significant effect on the percentage error as cardiac output increases. The precision error of ± 20% currently used for thermodilution measurement may be set too low and is dependent on the clinical setting.
