Brief summary

Transfusion in lung transplantation is common, and despite improved techniques and limitations in the use of mechanical circulatory support (MCS), the incidence of massive transfusion has remained stable over the years. The consequences of blood transfusion (blood cells, plasma, platelet concentrates) are deleterious for patients and increase primary graft dysfunction and mortality risk. Whole blood viscoelastic testing devices have shown its effectiveness in monitoring coagulation and fibrinolytic function during cardiac surgery, liver transplantation or trauma. So far, few delocalized biology tools have been evaluated in lung transplantation. The main objective of this study is to determine if the use of a transfusion algorithm based on whole blood viscoelastic test with Quantra® test reduce transfusion during lung transplantation.

Interventions

OTHERQuantra

The study plans to collect 2 additional 3 mL citrate tubes of venous blood in addition to the platelet and blood counts.

OTHERControl

The study plans to collect 1 additional 3 mL citrate tubes of venous blood in addition to the platelet and blood counts at each time.
