传统的观点强调在分娩中子宫排出胎儿的作用,而忽略了子宫颈的作用。前列腺素可成功地使不利于分娩的子宫颈成熟。然而,前列腺素是强的子宫兴奋药,治疗上给予前列腺素影响子宫颈是以直接的方式,还是由于子宫收缩间接地影响子宫颈,尚未解决。选择无妊娠并发症,胎儿枕前位,宫颈未成熟,已孕足月需引产的初孕妇女。实验分二组,Foley组,即只羊膜外插入Foley氏管;Foley+Tylose(纤基醋酸钠)组,即除插入Foley氏管外,还通过Foley氏管羊膜外注入纤基醋酸钠胶的混悬液。Foley氏管进入宫颈5 cm,用30ml0.9%
The traditional view emphasizes the role of the uterus in the delivery of the fetus, while ignoring the role of the cervix. Prostaglandins can successfully make the cervix unfit for childbirth mature. However, prostaglandins are potent inhibitors of uterine excitability, whether the administration of prostaglandins to the cervix in a direct manner, or whether the contraction of the uterus indirectly affects the cervix, remains unresolved. Choose no pregnancy complications, the fetus anterior occipital, cervical immature, pregnant women have full term need of abortion. The experiment was divided into two groups, the Foley group, that is, the Foley’s tube was inserted only outside the amniotic membrane; the Foley’s + Tylose group was injected into the Foley’s tube through the amniotic membrane in addition to the Foley’s tube Suspension. Foley’s tube into the cervix 5 cm, with 30ml0.9%
