Abstract: (5401 Views)
At the present, many drugs are used for inhibition of uterine contractions,
but the proportions of preterm labors are increasing. Although magnesium sulfate
is the most commonly prescribed parenteral tocolytic agent, but its optimal use
has yet to be delineated. In this study a high-dose protocol for magnesium sulfate
tocolytic therapy was compared with a low-dose regimen. One-hundred patients
admitted to the labor unit of Imam Reza's hospital with preterm labor were enrolled
in the trial. The median times to successful tocolysis were 8 hours in the
low-dose group and 4 hours in the high-dose group (p<0.001). Patients treated
with higher doses were also more likely to spend significantly less time in the
labor and delivery unit (p<0.001). The median gestational age at delivery was 33
weeks in the low-dose group and 36 weeks in the high-dose group (p=O.OO l).
There were not any statistically significant differences between the two groups
with respect to pre- and post magnesium infusion side effects. These results suggest
that in the high-dose group, tocolysis was achieved more rapidly and patients
required shorter admissions to the labor and delivery unit without increased maternal
or neonatal morbidity.
