Effect of prophylactic outpatient administration of fenoterol on the time of onset of spontaneous labor and fetal growth rate in twin pregnancy

Abstract

A double-blind trial was conducted on outpatients with twin gestations to assess the effect of prophylactic administration of fenoterol on the fetal growth rate and the timing of the spontaneous onset of labor. No significant differences could be shown between the fenoterol-treated group of patients and the control group given a placebo. It is concluded that prophylactic administration of fenoterol does not have a significant effect upon the incidence of preterm labor or growth retardation in twin pregnancy.
