Multicenter Study
Accuracy of an autocalibrated pulse contour analysis in cardiac surgery patients: a bi-center clinical trial.
Less-invasive and easy to install monitoring systems for continuous estimation of cardiac index (CI) have gained increasing interest, especially in cardiac surgery patients who often exhibit abrupt haemodynamic changes. The aim of the present study was to compare the accuracy of CI by a new semi-invasive monitoring system with transpulmonary thermodilution before and after cardiopulmonary bypass (CPB). ⋯ Semi-invasive CI by autocalibrated pulse contour analysis showed a poor ability to estimate CI compared with transpulmonary thermodilution. Furthermore, the new semi-invasive device revealed an acceptable trending ability for haemodynamic changes only after CPB.

Multicenter Study
The use of extracorporeal carbon dioxide removal to avoid intubation in patients failing non-invasive ventilation - a cost analysis.
To evaluate the economic implications of the pre-emptive use of extracorporeal carbon dioxide removal (ECCO2R) to avoid invasive mechanical ventilation (IMV) in patients with hypercapnic ventilatory insufficiency failing non-invasive ventilation (NIV). ⋯ Additional costs for the use of arterio-venous ECCO2R to avoid IMV in patients with acute-on-chronic ventilatory insufficiency failing NIV may be offset by a cost reducing effect of a shorter length of ICU and hospital stay.
