Amniocentesis and drainage were performed in 19 twin pregnancies initially seen at less than 28 weeks' gestation with acute polyhydramnios caused by the twin-twin transfusion syndrome. The procedure was performed an average of three times for each patient (range one to six), with the removal of a mean volume of amniotic fluid of 2600 ml on each occasion (range 500 to 6700 ml). The interval between initial examination and delivery averaged 7 weeks (range 1 day to 18 weeks); 14 (37%) of the 38 babies survived the neonatal period. In the pregnancies with poor outcomes, the intertwin disparity in fetal size and the mean volume of amniotic fluid drained at each amniocentesis were greater than in the pregnancies in which one or both twins survived.
对19例双胎妊娠进行了羊膜腔穿刺及羊水引流，这些双胎妊娠最初在妊娠28周前被诊断为双胎输血综合征导致的急性羊水过多。每位患者平均进行该操作3次（范围为1至6次），每次平均抽取羊水2600毫升（范围为500至6700毫升）。初次检查至分娩的间隔平均为7周（范围为1天至18周）；38例婴儿中有14例（37%）存活至新生儿期。在结局不佳的妊娠中，双胎间胎儿大小差异及每次羊膜腔穿刺引流的平均羊水量均大于有一个或两个胎儿存活的妊娠。
