我院妇产科于1979年以来根据子宫收缩强弱应用低浓度催产素引产,催产失败后又应用4％～5％浓度催产素引产催产94例取得了较理想的临床效果。1 资料和方法1.1 年龄:本组年龄18～44岁,以20～30岁组最多占78例。1.2 催产素给药方法:5％或10％葡萄糖500ml加催产素2.5u或5u,从每分钟10滴开始,以达到每10分钟有2～3次阵缩为宜。需专人监护;根据宫缩强弱调整滴速,滴速每分钟不超过60滴。对无宫缩或宫缩不良,增加滴速如仍无效者可增加催产素浓度,500ml液体中加催产素10u,15u,均以每 Obstetrics and Gynecology in our hospital since 1979, according to the application of low concentration of oxytocin induced abortion, oxytocin failure, and then applied 4% to 5% oxytocin oxytocin induced 94 cases achieved better clinical results. 1 Materials and Methods 1.1 Age: The group aged 18 to 44 years, 20 to 30-year-old group accounted for a maximum of 78 cases. 1.2 Oxytocin administration: 5% or 10% glucose 500ml plus oxytocin 2.5u or 5u, starting from 10 drops per minute, in order to achieve every 10 minutes 2 to 3 times the contraction is appropriate. Need specialist custody; adjust the drip rate according to the contractions strength, drip rate does not exceed 60 drops per minute. No contractions or uterine contractions, increasing the drip rate is still ineffective can increase oxytocin concentration, 500ml of liquid plus oxytocin 10u, 15u, all at
