Son objectif est de dresser un état des lieux de la prise en charge des patients opérés cardiaques au CHU de Liège, des pratiques d’épargne sanguine qui y sont employées et de leur impact sur le recours à la transfusion, les durées de séjour et la mortalité. Cet audit devrait permettre de 1) mettre en évidence les éléments pouvant être améliorés dans l’organisation actuelle de la prise en charge de ces patients afin de concourir aux objectifs d’épargne sanguine 2) servir de base à l’élaboration d’un itinéraire clinique du patient opéré cardiaque.

We observed a significant decrease of serum ACE levels in the absence of pulmonary circulation, suggesting that in man the lungs were the major source of circulating ACE. An effective extra-pulmonary liberation of ACE could take place during cardiopulmonary bypass. The levels of serum ACE increased with pulmonary recirculation, but preoperative levels were not reached 24 h later.

Recent theoretical developments emphasize changes in directed functional (i.e., causal) connectivity as reflected in quantities such as 'integrated information' and 'causal density'. Here we develop and illustrate a rigorous methodology for assessing causal connectivity from electroencephalographic (EEG) signals using Granger causality (GC). Our method addresses the challenges of non-stationarity and bias by dividing data into short segments and applying permutation analysis. We apply the method to EEG data obtained from subjects undergoing propofol-induced anaesthesia, with signals source-localized to the anterior and posterior cingulate cortices. We found significant increases in bidirectional GC in most subjects during loss-of-consciousness, especially in the beta and gamma frequency ranges. Corroborating a previous analysis we also found increases in synchrony in these ranges; importantly, the Granger causality analysis showed higher inter-subject consistency than the synchrony analysis. Finally, we validate our method using simulated data generated from a model for which GC values can be analytically derived. In summary, our findings advance the methodology of Granger causality analysis of EEG data and carry implications for integrated information and causal density theories of consciousness.

Recent electrophysiological reports suggest that while initial propofol infusion provokes an increase in fast rhythms (from beta to gamma range), slow activity (from delta to alpha range) rises selectively during loss of consciousness. Dynamic causal modeling was used to investigate the neural mechanisms mediating these changes in spectral power in humans. We analyzed source-reconstructed data from frontal and parietal cortices during normal wakefulness, propofol-induced mild sedation, and loss of consciousness. Bayesian model selection revealed that the best model for explaining spectral changes across the three states involved changes in corticothalamic interactions. Compared with wakefulness, mild sedation was accounted for by an increase in thalamic excitability, which did not further increase during loss of consciousness. In contrast, loss of consciousness per se was accompanied by a decrease in backward corticocortical connectivity from frontal to parietal cortices, while thalamocortical connectivity remained unchanged. These results emphasize the importance of recurrent corticocortical communication in the maintenance of consciousness and suggest a direct effect of propofol on cortical dynamics.
