为了建立一种安全、有效、可接受的终止早孕前促进宫颈成熟的方法,本研究比较宫颈内插入海藻棒和阴道内置PGE_2之间的相对效能和副作用。 PGE_2栓剂含量为3mg;海藻棒直径为5mm,经γ射线辐照消毒。研究对象为40例初孕妇,15～45岁,要求经阴道终止早孕;均于手术前一天入院;当晚随机使用PGE_2或海藻棒。PGE_2栓剂置阴道后穹窿顶端;海藻棒不用宫颈钳、直视下无菌插入宫颈。所有操作均为同一研究者进行。12～16小时后(麻醉前)取出海藻棒或检查PGE_2栓是否已完全溶解。全麻后,用Hegar扩张器逐步扩张宫颈并吸宫止孕。扩张宫颈前记录能顺利通过宫颈内
In order to establish a safe, effective, and acceptable method of stopping cervical ripening prior to first trimester, this study compared the relative efficacy and side effects of intracervical insertion of alginate sticks with intravaginal PGE 2. PGE 2 suppository content of 3mg; seaweed rod diameter of 5mm, irradiated by γ-ray disinfection. The subjects were 40 first pregnant women, 15 to 45 years old, requiring vaginal termination of early pregnancy; were hospitalized the day before surgery; the night of random use of PGE 2 or seaweed rods. PGE_2 suppository vaginal vault set the top; seaweed bar without cervical forceps, aseptic insertion of the cervix under direct vision. All operations are performed by the same researcher. After 12 to 16 hours (before anesthesia) remove the algae sticks or check whether the PGE2 plug has completely dissolved. After general anesthesia, with Hegar dilator gradually expand the cervix and suction to stop pregnancy. Expansion of the cervix before the record can be successfully passed through the cervix
