Cardiopulmonary bypass (CPB) during cardiac surgery mechanically circulates and oxygenates the blood, bypassing the heart and lungs. Despite limited evidence, maintaining mechanical ventilation (MV) during CPB is recommended, as ventilator strategies during surgery may reduce the occurrence of postoperative infections. We aimed to determine whether...

Background The COVID-19 pandemic had a global impact on people life, notably because of lockdown periods. This could particularly affected patients suffering from hip fracture, who could have been more isolated during these periods. We aim at evaluating the impact of the COVID-19 period (including lockdown periods) on quality of life (QOL) in older...
Article
Pulmonary embolism is a common complication after intracranial hemorrhage. As thrombolysis is contraindicated in this situation, surgical pulmonary embolectomy may be indicated in case of high-risk pulmonary embolism but requires transient anticoagulation with heparin during cardiopulmonary bypass. We report the case of a patient with a history of...

Iron deficiency (ID) is very frequent in cardiac patients and has been associated with altered cardiac function. The correction of ID in patients with heart failure improves clinical symptoms, in patients with or without anemia [1, 2]. Alteration of mitochondrial metabolism due to ID may be responsible for these observations.

La fréquence de la carence martiale en réanimation est probablement sous-évaluée du fait d’un diagnostic difficile en présence d’inflammation. La découverte de l’hepcidine, principal régulateur du métabolisme du fer, a ouvert des perspectives pour le diagnostic et l’intérêt du traitement martial en réanimation.
Article
Critically ill patients have a high prevalence of anemia. Some of them are already anemic at intensive care unit (ICU) admission, because of surgery, trauma, or their medical history; and around 80 % of them are anemic at ICU discharge. The mechanisms underlying this anemia are multiple and often entangled. Two main mechanisms are involved: inflamm...
Article
Iron is the most prevalent oligo-nutriment and plays a key role in oxygen transport and energy production. Iron deficiency could lead to anemia but also to fatigue or muscular weakness. Iron metabolism is a closed circuit, finely tuned by the peptidic hormone hepcidin to avoid overload as well as deficiency. Inflammation and iron deficiency have op...
