To the Editor.—
The article by Hocker et al, "Extracorporeal Membrane Oxygenation and Early Onset Group B Streptococcal Sepsis,"1 purports to show that extracorporeal membrane oxygenation (ECMO) is effective in Group B Sepsis. The study begins comparing results prior to ECMO therapy with results after ECMO therapy. The incidence of death from Group B Sepsis went from 3 of 28 or 11% prior to the institution of ECMO to 9 of 53 or 17% after the institution of ECMO.
