将 2 31例早孕妇女人工流产术前随机分为四组 :A组 (n =5 2 )口服米非司酮 2 5mg ,每日 2次 ,共 4次 ;B组 (n =6 0 )米索前列醇 6 0 0 μg ,顿服 ;C组 (n =6 3)宫术安栓 0 4g纳肛 ;D组 (n =5 6 ,对照组 ,不用任何药物 )。用Hegar宫颈扩张器测试无阻力通过宫颈内口的最大直径 (X±S mm) ,A、B、C、D组分别为 7 2 2± 0 71,7 11± 0 72 ,5 6 2± 0 74,4 6 3± 0 84。经统计学分析A、B组与C、D组有显著性差异 (P <0 0 0 1)。结果显示米非司酮和米索前列醇对早孕宫颈有较为肯定的松弛作用。
A total of 231 preterm pregnant women were randomly divided into four groups: group A (n = 5 2), oral mifepristone 25 mg twice daily for 4 times; group B (n = 60) Soprostigum 600 μg, Dayton service; C group (n = 6 3) Gong surgery safety suppository 0 4 g anal; group D (n = 5 6, the control group without any drug). The maximum diameter of the cervical intraoral ostium (X ± S mm) without resistance was measured by Hegar cervical dilator. The diameters of group A, B, C and D were 7 2 2 ± 0 71,7 11 ± 0 72 and 5 6 2 ± 0 74,4 6 3 ± 0 84. Statistical analysis A, B group and C, D group was significantly different (P <0 0 0 1).
