盐酸利托君治疗前置胎盘的临床探析

Clinical Study on Ritodrine Hydrochloride in Treatment of Placenta Previa

目的对前置胎盘应用盐酸利托君治疗的临床疗效进行探讨分析。方法选取于2013年3月-2016年1月在我院接受治疗的前置胎盘患者98例,并1：1随机分为对照组和实验组各49例,观察并比较分别应用硫酸镁和盐酸利托君治疗的效果。结果实验组患者的24 h阴道出血停止率、保胎成功率、妊娠至足月率均高于对照组[91.84%、95.92%、85.71%vs.71.43%、73.47%、91.22%];同时实验组患者的延长孕周数、显效时间、新生儿体质量以及1 min Apgar评分均优于对照组,组间差异经t检验,有统计学意义（P〈0.05）。结论前置胎盘应用盐酸利托君治疗的临床疗效十分理想,能够使出血情况快速控制,对提高保胎成功率以及改善妊娠结局具有至关重要的作用。

Objective Clinical effect of ritodrine hydrochloride in treatment of placenta previa is to be studied. Methods Chose 98 patients with placenta previa who were treated in hospital from March 2013 to January 2016 and separated them into two groups at random according to 1 ：1 ratio with 49 patients in each group,and then observed and compared magnesium sulfate treatment effect to ritodrine hydrochloride treatment effect between two groups. Results Patients＇ 24 h vaginal blood-stopping rate,abortion-prevention success rate and termed-pregnancy rate in study group are much shorter than counterparts in control group [91.84%、95.92%、85.71% vs. 71.43%、73.47%、91.22%],besides,patients＇ assessment scores in terms of extended gestational weeks,effect taking-into time,new-born physical quality and 1 min Apgar in study group were much more favorable than counterparts in control group; there was a differential between two groups and such a differential had statistic value according to T-Check（P〈0.05）. Conclusion Ritodrine hydrochloride is effective in treatment of placenta previa,it is conducive to stopping bleeding symptom,which is significant to increase abortion-prevention success rate and improve gestational outcome.
