近年来我科采用雷夫诺尔中期引产选择记录完全1000例作临床分析。本组经产妇占61％,初产妇39％,最孕小周12周,最大孕周38周,一次注药成功率达97.1％,一次注药不成功等待4至5天第二次给药,总成功率99.2％。胎儿排出时间最短8小时,最长120小时,21—25孕周胎儿胎盘排出时间最短平均11.7小时。我们体会羊膜腔注药较羊膜腔外注药方便易行,并可避免逆行感染,本组12周以下因羊水少,采用腔外注药,余均为腔内注药。用药剂量与孕月成比例,最小40mg,最大100mg,效果均满意,晚孕采用胎体注药娩出均为死胎。本组胎盘胎膜残留发生率较高占68.7％这也是造成产后出血的原因之一。一年来对每例病人常规投以生化汤加减,对减少产后出血起到一定的作用。雷夫诺尔引产临床实践证明反应小,患者愿意接受,且药源充足,制剂方便,操作简单安全利于医务人员掌握,可配合计划生育工作大规模开展。
In recent years, our department used Lefranor mid-term induction of labor to choose a full record of 1000 cases for clinical analysis. The group accounted for 61% of mothers, primipara 39%, the most weekly week 12, the maximum gestational age of 38 weeks, a successful injection rate of 97.1%, one injection unsuccessful wait for 4 to 5 days the second dose , The total success rate of 99.2%. Fetal discharge time of at least 8 hours, up to 120 hours, 21-25 gestational weeks, the shortest placenta discharge time of an average of 11.7 hours. We understand that amniotic cavity injection of amniotic fluid injection more convenient and feasible, and to avoid retrograde infection, the group less than 12 weeks due to amniotic fluid, the use of extraluminal injection, the remaining intracavity injection. Medication dose proportional to pregnancy, the minimum 40mg, maximum 100mg, the effect is satisfactory, the use of carcass injection of late pregnancy are all stillbirths. This group of placenta fetal membranes accounted for a higher incidence of residual 68.7% This is one of the causes of postpartum hemorrhage. A year for each patient routine cast with biochemical soup addition and subtraction, to reduce postpartum hemorrhage played a role. The clinical practice of Lefkonor induction of labor has proved that the reaction is small and the patients are willing to accept it. Moreover, the medicine source is sufficient, the preparation is convenient, the operation is simple and safe, which is beneficial to the medical personnel to grasp and can be carried out on a large scale with the family planning work.
