—We thank the correspondents for their interest in our work, which demonstrated improved survival with the addition of IAC to otherwise standard CPR.¹ Drs Gregory and Tucker raise concern regarding our resuscitation and discharge rate for the standard CPR group. We would like to point out, however, that in our study, 61% of patients in the standard CPR group presented with asystole or electromechanical dissociation. Although Bedell et al² reported a discharge rate of 14% after in-hospital cardiac arrest, 33% of patients in that study had ventricular tachycardia/fibrillation as an initial mechanism of arrest, and 27% of patients experienced primary respiratory arrest only. In the study by George et al,³ to which Dr Gregory refers, the overall discharge rate was 34%, but no patient with electromechanical dissociation and only 12.5% of patients with asystole survived to hospital discharge. Differences in these cardiac-arrest variables make direct . . . [Full Text PDF of this Article]
