目的：比较单用硫酸镁与硫酸镁联合拉贝洛尔治疗妊娠期高血压的临床疗效。方法选取2012年1月~2014年12月我院收治的86例妊娠期高血压患者为研究对象，随机分为观察组与对照组，每组43例；对照组单用硫酸镁治疗，观察组应用硫酸镁联合拉贝洛尔治疗。比较两组患者的收缩压与舒张压的变化情况及治疗效果。结果治疗2个疗程后两组患者的收缩压和舒张压较治疗前均有所下降，但治疗后观察组患者的收缩压和舒张压明显低于对照组，差异均具有统计学意义(﹤0.05)，治疗2个疗程后观察组治疗总有效率优于对照组，差异均具有统计学意义(﹤0.05)。结论硫酸镁联合拉贝洛尔治疗妊娠期高血压的临床疗效优于单用硫酸镁。“,”Objective To compare the clinical ef icacy of magnesium sulfate and magnesium combined sulfate labetalol in the treatment of hypertensive disorders in pregnancy.Methods 86 cases of hypertensive disorders in pregnancy were included the study from January 2012 to December 2014 in our hospital,and randomly divided into control group and observation group,43 cases in each group;the control group was used magnesium sulfate,the observation group was used magnesium sulfate and labetalol.The systolic pressure,diastolic pressure and curative ef ect were compared in two groups.Results After two courses of treatment,the systolic pressure and diastolic pressure were less than before treatment,but the systolic pressure and diastolic pressure of observation group were significantly lower than the control group,the dif erences were statistical y significant ( ﹤0.05).The total ef ective rate of observation group was obviously higher than that of the control group,the dif erences were statistical y significant ( ﹤0.05).Conclusion The clinical ef icacy of magnesium sulfate combined labetalol in treatment of hypertensive disorders in pregnancy was bet er than single magnesium sulfate.
