胎儿在宫内的情况可以通过羊水中某些溶质(如磷脂、肌酐、胆红素、酶等)的测定,超声图和羊膜腔造影术等方法来测知。尤其是羊水中各种成分的变化能在很短时间内立即反映胎儿的情况,这表明了羊水和胎儿之间的转换是经常的,而且量是相当可观的。但是,我们对于羊水流量的调节和羊水成分变化的基础知识仍在探索中。为此,本文叙述了羊水动力学最近的发展。以往的概念以往有许多关于羊水形成和调节的概念。总的来说,这些概念都认为羊水的调节是静态的,目前已被否定。因在探索羊水生理学时,常被提及,故在此再作简述。一、羊膜上皮或平滑绒毛膜能分泌水份
Fetal intrauterine conditions can be determined by the amniotic fluid of certain solutes (such as phospholipids, creatinine, bilirubin, enzymes, etc.), ultrasound and amniocentesis and other methods to detect. In particular, changes in the composition of amniotic fluid in a very short time immediately reflect the situation of the fetus, indicating that the conversion between amniotic fluid and the fetus is frequent, and the amount is considerable. However, our basic knowledge of the regulation of amniotic fluid flow and changes in amniotic fluid composition is still under investigation. To this end, this article describes the recent development of amniotic fluid dynamics. Previous concepts There have been many concepts of amniotic fluid formation and accommodation in the past. All in all, these concepts all agree that the conditioning of amniotic fluid is static and has now been denied. Because in the exploration of amniotic fluid physiology, often referred to, so here again briefly. A, amniotic epithelium or smooth chorion can secrete moisture
