我院自1980年2月至6月,将妊娠10～18周中期引产孕妇,用超声波定位组100例和对照组100例进行比较,介绍如下: 一、方法由于羊膜腔穿刺注射引产范围的扩大,对穿刺技术的要求也需要提高。按“利凡诺羊膜腔内注射引产操作常规”选择穿刺点,往往很难一针穿刺成功,尤其是对小月份小子宫和大月份胎儿充满羊膜腔的大子宫,一针成功率更低。常误入胎盘,抽出血性泡沫和血液来,往往多次穿刺才能成功,甚至失败。
Our hospital from February 1980 to June, 10 to 18 weeks gestation midwifetal pregnant women, with 100 cases of ultrasound positioning group and control group of 100 patients were compared, described as follows: First, the method due to the expansion of amniocentesis induced abortion , The need for puncture technology also needs to be improved. According to “Richeno amniotic intramuscular injection induction operation routine” to select the puncture point, it is often difficult to puncture the success of a needle, especially for the small month of small jaundice and large fetus amniotic fetal large uterus, a lower success rate of a needle. Often mistaken for the placenta, pumping out bloody bubbles and blood, often puncture in order to succeed, or even failure.
