An extra-uterine system to physiologically support the extreme premature lamb

Abstract

In the developed world, extreme prematurity is the leading cause of neonatal mortality and morbidity due to a combination of organ immaturity and iatrogenic injury. Until now, efforts to extend gestation using extracorporeal systems have achieved limited success. Here we report the development of a system that incorporates a pumpless oxygenator circuit connected to the fetus of a lamb via an umbilical cord interface that is maintained within a closed ‘amniotic fluid’ circuit that closely reproduces the environment of the womb. We show that fetal lambs that are developmentally equivalent to the extreme premature human infant can be physiologically supported in this extra-uterine device for up to 4 weeks. Lambs on support maintain stable haemodynamics, have normal blood gas and oxygenation parameters and maintain patency of the fetal circulation. With appropriate nutritional support, lambs on the system demonstrate normal somatic growth, lung maturation and brain growth and myelination.

我无所谓……反正我不想生。如果想养人玩(?)那也只领养
我绝对不把生命带到这个世界受苦。

领养的孩子也是要通过子宫才能出生。
领养没那么容易。

我的意思是,领养的前提是已经出生了。对已经出生的我希望尽可能创造美好,,,没出生的,还是不要带来这个世界上了。(思想有点黛玉……)

据我所知,26周之前没有存活记录。

是,我印象里也是约 30 多周后比较稳妥。
感觉有曙光了,但是离实用化可能还有10年以上的距离。
