Hemodynamic Monitoring, Positive Inotropic and Vasoactive Drugs During Cardiac Surgery (EMOA) (EMOA)

The perioperative management in cardiac surgery patients has changed dramatically in the last fifteen years with the development of new cardiac output monitoring devices, the availability of new inotropic molecules, and a modern treatment for cardio-circulatory failure.

However, few studies report the possible changes in practice. The last French national survey was conducted in 2001. Since then, the literature is poor on the subject, and the impact of new approaches has been only marginally addressed. Recently, a German postal survey was conducted among cardiac surgery anesthesiologists, but on purely declarative elements and without patient data.

The investigators offer a type of national prospective observational study to evaluate professional practices, morbidity and mortality in cardiac surgical patients. This study must include all patients undergoing cardiac surgery at the participating centers during 7 weeks.

The main objective of this work is to assess the proportion of patients undergoing cardiac surgery receiving a cardiac output monitoring.

Secondary objectives are to describe the relationship between the use of cardiac output monitoring and the use of positive inotropic agents and vasoactive (type molecules, duration), volume expansion and transfusions the first 24 hours, and the incidence postoperative complications for patients undergoing cardiac surgery.
