作者对150名初产妇应用不同催产方法进行比较.产妇均为足月产,年龄20～25岁,胎头已入盆,宫颈管消失,在宫颈开3cm时破膜,随机分作5组.第一组用催产素静脉滴注:5%葡萄糖溶液500ml中加催产素5U.开始2mU/分钟,以后每次加2mU直到富缩规律,即每2分钟宫缩一次.第二组用金雀花碱静脉滴注:5%葡萄糖溶液500ml中加金雀花碱600mg,开始6mg/分钟,以后每次加6mg,直到宫缩规律.第三组用金雀花碱肌注:每次200mg,每30分钟1次,共3次.第四组用前列腺素F_2α静脉滴注:5%葡萄糖溶液500ml中加前列腺素5mg,开始5μg/分钟,以后每次加2μg直到宫缩规律.第五组用催产素静脉滴注同第一组,
The authors compared 150 primiparous women with different methods of giving birth, all of whom were full-term, aged 20 to 25 years old. The fetal head had been introduced into the basin and the cervical canal disappeared. The cervix was ruptured 3 cm apart and randomly divided into 5 groups. The first group with intravenous infusion of oxytocin: 500ml of 5% glucose solution plus oxytocin 5U. Start 2mU / min, then add 2mU each time until the law of contraction, that is contractions every 2 minutes. Theophylline intravenous infusion: 500ml of 5% glucose solution plus jacanitine 600mg, start 6mg / min, after each plus 6mg, until the contractions of the law. The third group with goseal intramuscular injection: Each 200mg, Every 30 minutes, a total of 3. The fourth group with intravenous infusion of prostaglandin F_2α: 5% glucose solution 500ml plus prostaglandin 5mg, start 5μg / min, then add 2μg each time until the contractions. With oxytocin intravenous infusion with the first group,
