ABSTRACT
The management of premature labor by the prolonged infusion of diazoxide was evaluated in 33 pregnant baboons. The drug was administered intravenously to the mother with an average rate of 0.065 mg/kg/min for 4 hours. Mild to moderate spontaneous labors were significantly inhibited by diazoxide without jeopardizing the fetus. Diazoxide produced a significant increase in maternal heart rate, but its effect on fetal circulation was minimal. Fetal acid-base state and arterial oxygenation remained essentially unchanged throughout the period of observation. Intravenous administration of this drug to the fetuses caused only mild cardiovascular changes irrespective of its preexisting conditions. Thus, a slow intravenous infusion of diazoxide to the mother in a low dosage appears to be of value for inhibiting the uterine activity in early labor, without interfering with the fetal well-being.
