What this trial studies

This trial investigates the feasibility of different red blood cell (RBC) transfusion triggers in patients receiving Extracorporeal Membrane Oxygenation (ECMO), a life-support technique for critically ill patients. It aims to determine the optimal hemoglobin (Hb) levels for transfusion that balance the risks of anemia against the potential complications of transfusions. The study will assess how low Hb levels can be tolerated in ECMO patients, who have unique physiological needs and higher risks compared to the general critically ill population. By establishing safe transfusion thresholds, the trial seeks to improve patient outcomes and guide clinical practice.

Who should consider this trial

Good fit: Ideal candidates for this study are adults aged 18 years or older who are currently receiving ECMO treatment.

Not a fit: Patients with contraindications to RBC transfusion or those whose ECMO treatment is expected to cease shortly may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to safer transfusion practices and improved outcomes for critically ill patients on ECMO.

How similar studies have performed: While other studies have explored transfusion strategies in critically ill patients, this specific approach in the ECMO cohort is novel and has not been previously tested.

Eligibility criteria

Show full inclusion / exclusion criteria
Inclusion Criteria:

* Patients receiving ECMO
* Age: 18 years or older

Exclusion Criteria:

* Contraindication to RBC transfusion (including known patient preference)
* Limitations of care put in place either through patient wishes or the treating medical teams
* ECMO treatment for more than 12 hours. The start of ECMO is defined as the time of initiation of extracorporeal blood flow unless ECMO was initiated during a surgical intervention in which case the start is defined as the arrival time into the initial ICU.
* The treating physician anticipates that ECMO treatment will cease before the end of tomorrow
* Where the treating physician deems the study is not in the patient's best interest
* Where the treating physician has concern regarding patient ability to tolerate restrictive or liberal transfusion trigger thresholds
* Patients actively listed for a solid organ transplant
* Patients who are suspected or confirmed to be pregnant
* Previous ECMO treatment during the same hospital admission
