Summary

Extracorporeal membrane oxygenation (ECMO) is of great value in supporting patients with cardiac shock. More than 80% ECMO patients will develop renal catastrophe that continuous renal replacement therapy (CRRT) is required. The evidence is conflict as to whether early CRRT improves outcomes. Early CRRT before a definite indication developed may prevent side effects of toxicity and fluid overload and therefore, bring survival benefit for the patient. This hypothesis need to be tested in RCT.

Plasma catecholamine levels can be very high in patients under VA-ECMO, which maybe toxic to the cardiac myocardium. Beta-blockers can antagonize the effects of catecholamine. In patients with VA-ECMO, the protective effect of beta-blocker may improve the patients' outcome. This hypothesis also need to be tested in RCT.

ELITE (Evaluation of Early CRRT and Beta-blocker InTerventions in Patients with ECMO) study is a factorial designed RCT with the purpose to test the benefit of early CRRT and beta-blocker in patients treated with V-A ECMO. In the CRRT arm, patients will be randomized to simultaneous CRRT (not late than 24 hours after the initiation of ECMO) or routine therapy (CRRT when indicated). In the beta-blocker arm, patients will be randomized to beta-blocker treatment with a heart rate target of 75±5 bpm or routine therapy. The primary outcome is all-cause mortality at 30 days. Patients discharged alive will be followed for 1 year. Data of mortality and quality of life which are secondary outcomes of this study, will be collected.
