Blood Cells Transfusion, Extracorporeal Membrane Oxygenation Complication, Transfusion Related Complication
Conditions
Brief summary
The primary objective of this work is to study the 1-year prognosis of patients who received Veno-arterial extracorporeal membrane oxygenation for cardiogenic shock with the need for blood transfusion. Secondary objectives are to determine whether the transfusion strategy used (liberal or restrictive) still has an impact on overall mortality. We will also determine the factors associated with overall in-hospital mortality and look at the impact of transfusion in relation to the risk of hemolysis on the consequences in the occurrence of long-term chronic renal failure.
Detailed description
The study of the prognostic impact of blood transfusion at 1 year in patients assisted by Veno-arterial extracorporeal membrane oxygenation in the context of cardiogenic shock would provide objective answers and optimize the decision to set up this assistance with regard to the possible long-term consequences. This decision currently remains at the discretion of the expert teams managing these patients. The inclusion of patients in a state of cardiogenic shock under Veno-arterial extracorporeal membrane oxygenation with the need for transfusion, will therefore allow the elaboration of a multicentric observational study interested in the prognosis at 1 year of patients under VA ECMO according to the adopted transfusion threshold.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| 1-year survival | date of start of intensive care hospitalization to date of discharge from intensive care hospitalization assessed up to 1 year | To evaluate the association of blood transfusion (and its volume of administration) with the 1-year prognosis of patients managed with Veno-arterial extracorporeal membrane oxygenation for medical or post cardiotomy cardiogenic shock |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| All-cause mortality rate during hospitalization for cardiogenic shock with the need for Veno-arterial extracorporeal membrane oxygenation | date of start of intensive care hospitalization to date of discharge from intensive care hospitalization assessed up to 3 months | Assess the association between transfusion strategy as assessed by hemoglobin nadir during hospitalization with all-cause mortality. |
| 30-day mortality | date of start of intensive care hospitalization to date of discharge from intensive care hospitalization assessed up to 30 days | To evaluate the association of blood transfusion (and its volume of administration) with the 30-day prognosis of patients managed with Veno-arterial extracorporeal membrane oxygenation for medical or postcardiotomy cardiogenic shock |
| Number of patients with stage 4 chronic kidney disease (GFR <30 mL/min) or with the need for chronic dialysis at 30 days. | date of start of intensive care hospitalization to date of discharge from intensive care hospitalization assessed up to 30 days | Assess the association of transfusion strategy with the occurrence of chronic renal failure (GFR \<30 mL/min or with the need for chronic dialysis) at 30 days. |
| Number of patients with stage 4 chronic kidney disease (GFR <30 mL/min) or with need for chronic dialysis at 1 year. | date of start of intensive care hospitalization to date of discharge from intensive care hospitalization assessed up to 1 year | Evaluate the association of transfusion strategy with the occurrence of chronic renal failure (GFR \<30 mL/min or with the need for chronic dialysis) at 1 year |
