Comparative Study
Evaluation of a new semi-continuous cardiac output system in the intensive care unit.
A new semi-continuous thermodilution cardiac output (CCO) system has been developed recently (Opti-Q and Q-vue Abbott critical care system). The aim of this study was to compare the accuracy and reproducibility of this new device with conventional ice-bolus thermodilution cardiac output (BCO). ⋯ Compared with BCO, this new device was accurate but cannot be considered as interchangeable regarding the limits of agreement. Reproducibility of CCO was superior to BCO.

To assess the effect of pneumoperitoneum on P(a-ET)CO2 gradient in children. ⋯ PETCO2 often overestimates PaCO2 during laparoscopy in children, by up to 8.8 mmHg. Arterial blood gas analysis should be performed during long procedures to avoid hyperventilation.
