Abortion and embryo / foetal loss
流產(chǎn)和胚胎及胎兒損失
Abortion means the premature expulsion of dead or non-viable foetuses. Embryo loss occurs when there is death of embryos followed by absorption, or expulsion. Healthy embryos grow into foetuses.
流產(chǎn)意味著早期排出死亡或者不能存活的胎兒。胚胎損失通常發(fā)生在有胚胎死亡時(shí),經(jīng)常是伴隨著流產(chǎn)或娩出。健康的胚胎發(fā)育成胎兒。
There is often alarm when an abortion is seen but it should be remembered that there can be loss of embryos at any time during early pregnancy, which often go unseen.
在流產(chǎn)發(fā)生前,經(jīng)常會有前兆的,但是應(yīng)當(dāng)記住,在妊娠早期隨時(shí)可能發(fā)生胚胎的死亡,而這些卻經(jīng)常是肉眼看不到的。
Embryo loss or abortion can be considered in three main groups:
胎兒損失或者流產(chǎn)可以歸為以下幾類:
During the period from fertilisation to implantation
從受精到著床階段
During the period of implantation at around 14 days post-service to 35 days.
從配種后,著床第14天到35天
During the period of maturation, which results in premature farrowings. It can be seen therefore that losses can take place at any stage from approximately 14 days after mating, when implantation has taken place, through to 110 days of pregnancy.
在胚胎發(fā)育成熟期間,通常會有早產(chǎn)。因此,胚胎損失大概從配種后14天起,在著床的任何階段,貫穿到110天妊娠期。 |
