Rebuttal from Dr Morris et al.

The authors presents a rebuttal to the response by Pauline Park and colleagues concerning their study on the use of extracorporeal membrane oxygenation (ECMO) in treating the 2009 influenza AH1N1. The authors assert that Park and colleagues should have considered rigorous clinical trials on extracorporeal life support which failed to produce proofs of the efficacy of ECMO in influenza-associated respiratory failure. They however applaud the call by Park for a reassessment of ECMO.
