Active Bleeding after Valve Surgery under Extracorporeal Circulation: Incidence and Risk Factors? Prospective Observational Study on 59 Patients in a West African Country

Active bleeding after cardiac surgery is defined as blood loss > 1.5 ml / kg / h for 6 consecutive hours within the first 24 hours or in case of re-operation for haemostasis within the first 12 hours postoperatively. The aim of our work was to assess the incidence and risk factors for the occurrence of active bleeding in postoperative valve surgery with extracorporeal circulation.
