A randomized, double-blind comparison of methoxamine and epinephrine in human cardiopulmonary arrest.
|
| Abstract |
The beneficial effect of epinephrine has been attributed to its alpha-adrenergic properties. The present study was designed to compare the effects of epinephrine and methoxamine in witnessed cardiac arrests. Consecutive, witnessed cardiac-arrest victims presenting to the emergency room or from the inpatient population of our institution were enrolled in this study. Patients were randomized to receive either epinephrine (2 mg bolus followed by 2 mg every 4 min) or methoxamine (40 mg bolus followed after 4 min by 40 mg) in a blind design. Patients were followed prospectively for survival and neurologic outcome. A total of 199 patients were randomized into the study, but 54 had to be retrospectively dropped from analysis for failure to comply with the study protocol. Of the 145 patients remaining, 77 received methoxamine (M) and 68 epinephrine (E). There was no difference in rate of successful resuscitation (42% versus 53%, M versus E, respectively), or in neurologic outcome as measured by the Glasgow-Pittsburgh Coma Score (GPCS). This study failed to demonstrate any difference in the rate of initial resuscitation, survival to discharge from the hospital, or neurologic status with methoxamine as opposed to epinephrine in the setting of cardiac arrest.
