许多近代研究中记载了羊水穿刺术的益处和危险。其可能的并发症包括自然流产、早破水、胎儿创伤、羊膜炎和胎儿-胎盘出血。行羊水穿刺术的病人60%为前壁胎盘、常需穿过胎盘刺入。虽一般认为穿过胎盘抽液增加妊娠损伤的危险,但客观论据不足。本文致力于穿过胎盘的羊水穿刺术对妊娠损失的影响。作者对1979年1月1日～1981年7月30日间行羊膜穿刺术的998例病人的妊娠结果进行分析。操作全部由一人,在实时超声描记下用22号脊髓穿刺针施行。穿刺点选择在离开胎儿和羊水深度最大的部位,尽可能避免穿入胎盘,当必需经胎盘穿刺时则选择胎盘边缘部并离开脐带附着处。结果指出:998例中有347例(35%)需经胎盘穿刺的。与不经胎盘者比较,妊娠结果及能影响妊
Many modern studies document the benefits and dangers of amniocentesis. Possible complications include spontaneous abortion, water breakthrough, fetal trauma, amniitis and fetal-placental hemorrhage. Amniocentesis patients 60% of the anterior wall of the placenta, often puncture through the placenta. Although it is generally believed that the liquid through the placenta increases the risk of pregnancy damage, but the objective argument is insufficient. This article focuses on the impact of amniocentesis through the placenta on pregnancy loss. The authors analyzed the pregnancy outcome of 998 patients who underwent amniocentesis between January 1, 1979 and July 30, 1981. All were performed by a single person under the real-time sonography with a 22-gauge spinal needle. Puncture point to leave the fetus and amniotic fluid in the depth of the largest parts, as far as possible to avoid penetrating the placenta, placental puncture when the need to select the edge of the placenta and leave the umbilical cord attachment. The results indicate that 347 (35%) of 998 cases require placental puncture. Compared with non-placenta, pregnancy results and can affect pregnancy
