About this study
Official title: A Randomised Controlled Trial of Venovenous ECMO to De-Sedate, Extubate and Mobilise in Hypoxic Respiratory Failure
To determine whether a strategy of adding venovenous ECMO to mechanical ventilation, as compared to mechanical ventilation alone, increases the number of intensive care free days at day 60, in patients with moderate to severe acute hypoxic respiratory failure.
Read the detailed description
Mechanically ventilated patients with moderate to severe acute hypoxic respiratory failure are at increased risk of dying, short and long-term health problems and are often very costly to treat. The mechanical ventilator, whilst often lifesaving, may harm patients in two ways i) directly via damage to the lungs (termed ventilator induced lung injury), and ii) indirectly via paralysis and sedation that patients require to tolerate mechanical ventilation. Paralysis and sedation can increase the risk of secondary infections, weakness, prolonged duration of intensive care, as well as long-term physical disability. There is a need to develop new treatments that support patients and at the same time reduce these complications.
Extracorporeal membrane oxygenation (ECMO) is a device that supports the lungs by adding oxygen and removing carbon dioxide from the blood. By providing non pulmonary gas exchange, veno-venous (VV) ECMO can reduce the need for the mechanical ventilator. This in turn can reduce the risk of lung damage, and also removes the need for sedating medications so that activities like physiotherapy can begin earlier.
The REDEEM trial is a phase 2, investigator initiated, multicentre randomised controlled trial that will recruit 140 patients with moderate to severe acute hypoxic respiratory failure. It is designed to test whether adding ECMO to the mechanical ventilator, as compared to using the mechanical ventilator on its own, leads to an increase in the number of patients who survive and are discharged earlier from the intensive care unit. If the REDEEM trial confirms adding ECMO is more effective than mechanical ventilation alone, it has the potential to change the current paradigm of intensive care treatment of hypoxic respiratory failure, and could lead to changes in practice globally.

What participants receive

Venovenous ECMOOther
ECMO therapy for patients with hypoxic respiratory failure.
| Study group | Role | What they receive |
|---|---|---|
| Venovenous ECMO | Active comparator | Patients allocated to the ECMO strategy be initiated on V-V ECMO and on anticoagulation (blood thinning medication to prevent clot formation) within 24 hours of being allocated into the intervention group. Anticoagulant medication to prevent clot formation will be initiated as per current local practice for each site. Sites are encouraged to use best practice ECMO management that includes de-sedation, extubation, commencement of physiotherapy and rehabilitation, Receives: Other: Venovenous ECMO |
| Standard care | No intervention | Patients allocated to the standard care arm will receive routine intensive care for hypoxic respiratory failure, including mechanical ventilation as per local practices, weaning of sedation and assessment for extubation. Patients who continue to deteriorate will be eligible for initiation of V-V ECMO if they meet the ECMO to rescue lung injury in severe ARDS (EOLIA) criteria: Partial pressures of arterial oxygen (PaO2):Fraction of inspired oxygen (FiO2)<50 for 3 hours, PaO2:FiO2<80 for 6 hours, pH<7.25 with PaCO2 >60 for >6 hours. |
What is being measured
