RT Journal A1 Laudi S, Busch T, Kaisers U T1 EXtracorporeal membrane oxygenation for ards due to 2009 influenza a(h1n1) JF JAMA JO JAMA YR 2010 FD March 10 VO 303 IS 10 SP 941 OP 942 DO 10.1001/jama.2010.200 UL http://dx.doi.org/10.1001/jama.2010.200 AB Only 20 patients (32%) were treated with inhaled nitric oxide before initiation of ECMO, although this therapy is considered an effective rescue treatment of refractory hypoxemia in acute lung injury.2 Moreover, it is not reported whether inhaled nitric oxide was continued on ECMO and what concentrations were used. In addition to providing selective pulmonary vasodilation, inhaled nitric oxide may be an effective topical anti-infective agent,3 with activity against the replication of influenza viruses in vitro.4 During the severe acute respiratory syndrome (SARS) epidemic, an antiviral effect on the SARS coronavirus was reported.5 It remains to be determined whether inhaled nitric oxide might be a therapy for H1N1-induced acute respiratory failure that could reduce the need for and the duration of ECMO treatment.
