羊水具有保护胎儿使其在羊膜腔内自由运动与正常发育的重要作用。随着检查技术的日益提高,羊水可以直接反应胎儿在子宫内的情况,并通过羊水可以研究胎儿的生理与病理变化。羊水检查是现代产科学的重要进展之一,在围产期医学领域中已成为出生前诊断的重要措施。羊水分为液性成分与细胞成分。通过羊水的液性成分检查可了解胎儿的成熟度和胎儿胎盘功能,并可诊断无脑儿和脊椎裂畸胎。羊水细胞成分的染色体分析可判断性别及某些遗传性疾病或畸胎。细胞成分的生化学分析主要
Amniotic fluid has an important role in protecting the fetus in the amniotic cavity free movement and normal development. With the increasing detection technology, amniotic fluid can directly reflect the fetus in the womb, and through the amniotic fluid can study the physiological and pathological changes in the fetus. Amniocentesis is one of the most important advances in modern obstetrics and has become an important prenatal diagnosis in perinatal medicine. Amniotic fluid is liquid components and cellular components. Check through the amniotic fluid components can understand the fetal maturity and fetal placental function, and can diagnose anencephalic and spina bifida. Chromosome analysis of amniotic fluid cell components can determine the gender and some genetic diseases or teratogenic. Biochemical analysis of cellular components
