Complications of amniocentesis include preterm labor and delivery,
respiratory distress, postural deformities, fetal trauma and
alloimmunisation of the mother (rhesus disease). Studies from the 1970s
originally estimated the risk of amniocentesis-related miscarriage at around
1 in 200 (0.5%).[10] Three more recent studies from 2000-2006 estimated the
procedure-related pregnancy loss at 0.6-0.86%. [11] A more recent study (
2006) has indicated this may actually be much lower, perhaps as low as 1 in
1,600 (0.06%). [12]. Unlike the previous studies, the number in this study
only reflects the loss that resulted from amniocentesis complications and
excluded the cases when parents decided for an abortion following the test
results。
所以那些1/200之类的比较高的risk是包含了父母发现胎儿异常后主动要求abortion的
。实际上我们关心的是羊穿这个技术本身导致的loss,所以后一个study给出的数值更
可靠。1:1600. |
