ABSTRACT

Objective To compare the clinical effect of three different methods in treatment of premature.Methods 150 premature patients were randomly divided into three groups,50 cases for each group,received treatments with ritodrine,magnesium sulfate plus salbutamol,or magnesium sulfate alone respectively. The tensity of uterine contraction, the interval between drug administrations and the relief of uterine contraction, the accumulative drug using time, the elongated pregnancy durations were observed for the dertermination of effectiveness. Results The group treated with ritodrine, magnesium sulfate plus salbutamol or magnesium sulfate were effective in 94%, 78%,70% of patients of each group, and it showed that ritodrine was more effective than the combination and magnesium sulfate. The intervals of drug using and contraction relief were statistically different among three groups, (2. 16 ±0. 91)h,(4. 14 ± 1.07)h,(5.12 ± 1.45) h for each(all P ＜0.05).The cumulative drug using times were(7. 04 ±1. 16) d, (7.46 ± 1.20) d, (7.06 ± 2.78) d for three groups and proved not to be statistically significant ( all P ＞0. 05 ). The elongated pregnancy durations were (22.08 ± 7.32 ) d, ( 17.42 ± 5.85 ) d and ( 11.82 ± 5.04 ) d, and significantly different in three groups ( all P ＜ 0. 05 ). Conclusion The treatment of premature with ritodrine or the combination of magnesium sulfate and salbutamol was superior to using magnesium sulfate alone.
