NCT05740059

Brief Summary

The goal of the clinical trial is to evaluate whether a restrictive transfusion strategy adjusted by SvO2 during the perioperative period of cardiac surgery may reduce the incidence of red blood cell transfusion. Adult patients operated on cardiac surgery will be randomly allocated into two groups, one receiving standard restrictive transfusion, the other receiving SvO2 adjusted restrictive transfusion.The proportion of patients transfused will be compared between the 2 groups.

Study Arms (2)

Control

NO INTERVENTION

Patients assigned to the Control group will be transfused if hemoglobin (Hb) concentration is lower than 9 g/d.

Adjusted transfusion

ACTIVE COMPARATOR

Patients assigned to the SvO2 group will be transfused if Hb concentration is lower than 9 g/dL and central SvO2 ≤ 65%.

Other: Adjusted Transfusion

Interventions

Patients assigned to the SvO2 group will be transfused if Hb concentration is lower than 9 g/dL and central SvO2 ≤ 65%. Transfusion will be repeated whenever Hb concentration is lower than 9 g/dL and central SvO2 ≤ 65% during surgery and in the ICU (until day 5). Central SvO2 will be measured on a blood sample obtained from the distal lumen of the central venous catheter. Oximetry will be used for measurement with a point-of-care of gas analysis.
