自应用卵磷脂/鞘磷脂的比率作为胎儿肺成熟试验以来,孕末期羊膜腔穿刺的应用明显增加。某医院从1973年的5％增加到1976年的10％。由于羊膜腔穿刺术的增加,为了减少失败和并发症,选择一适当的穿刺部位是非常必要的。有人认为耻上穿刺点常易刺破胎膜,高位穿刺点易失败、易损伤胎盘及胎儿。为此作者对耻上及项背穿刺点进行对比。在6个月内,作者选择妊娠36周以上、头先露、无前置胎盘患者154例然后随意分组,进行耻骨弓上穿刺和项背穿刺的对比。
Since the application of lecithin / sphingomyelin ratio as a fetal lung maturation test, the use of amniocentesis has significantly increased in late pregnancy. A hospital increased from 5% in 1973 to 10% in 1976. Due to the increased amniocentesis, in order to reduce the failure and complications, choose a suitable puncture site is very necessary. Some people think that shame puncture puncture often easy to puncture fetal membranes, high puncture point easy to fail, easy to damage the placenta and fetus. To this end the author shame on the back of the piercing points and compared. Within six months, the authors chose 154 patients with gestational age above 36 weeks, first exposed, and without placenta previa and then randomly grouped for suprapubic puncture and back puncture.
