Résumé
L’anémie de réanimation est une pathologie fréquente, concernant près de 80 % des patients, et associée à une morbimortalité importante. Sa physiopathologie repose sur un défaut de synthèse et d’effet de l’érythropoïétine et sur des perturbations majeures du métabolisme du fer. Une meilleure connaissance de ce métabolisme et de sa régulation par l’hepcidine offre de nouvelles pistes thérapeutiques. Pour le moment, une attention particulière aux spoliations sanguines et une prescription individualisée de la transfusion sanguine sont les principaux éléments de la prise en charge.
Abstract
Anaemia is frequent in the critically ill patients, present in almost 80% of them. Anaemia is associated with worse outcome and increased mortality. Its pathophysiology combines disturbances of erythropoietin synthesis and iron metabolism. The better understanding of iron metabolism regulation by the hormone hepcidin may offer new therapeutic perspectives. However, to date, anaemia management requires mainly prevention of blood spoliations, mainly by reducing blood sampling, and tailored blood transfusions.
