Transfusion Related Complication

This multicenter randomized controlled trial compare two transfusion strategies of red blood cells transfusion in patients supported by veno-arterial extracorporeal membrane oxygenation for refractory cardiogenic shock. An individualized transfusion strategy based on ScVO2 level, is compared to a conventionnal strategy based on predefined hemoglobin threshold. The primary endpoint is the consumption of packed red blod cells, secondary endpoints are subgroup analysis, mortality, morbidity, and cost-effectiveness

The Purpose of the study is to test the hypothesis that administration of an S-nitrosylating (SNO) agent can improve tissue oxygenation during transfusion of packed red blood cells (RBCs).

the aim of this register is to collect exhaustively the different data available surrounding a transfusion act in the context of an active haemorrhage. The aim is to allow different modelling and analysis related to emergency transfusion.

The present study is a multi-center randomized prospective placebo-controlled non-inferiority trial. The study's primary objective is to compare the amounts of postoperative bleeding using two different TXA administration strategies: empirical TXA administration vs. viscoelastic test-based goal-directed TXA administration in cardiovascular surgery. The secondary objectives include comparing the incidents of hyper-fibrinolysis, thromboembolic complications, and postoperative seizures. Researchers assumed that goal-directed tranexamic acid (TXA) administration using viscoelastic field tests would not be inferior to the empirical TXA administration strategy in reducing postoperative bleeding and hyper-fibrinolysis. It also would be beneficial in lowering TXA-induced thromboembolic complications and seizures.

In this trial, we proposed an individualized acute normovolemic hemodilution (ANH), and conduct a randomized controlled trial to testify the effect of individualized ANH on red cells requirement for non-cardiac surgeries with anticipating major blood loss in adults.

This study will allow correlating transfusion monitoring and patients' prognostic according to the chosen outcome criteria. These data could thus represent a basis for transfusion recommendations, except for intensive care and vital emergencies. It will also bring information about the actual transfusion monitoring in intensive care unit (ICU), in the period following the stay in the ICU and after hospital discharge.
