由于妊高症原因不明,但对母子的威胁大,孕产妇的并发症多,围产儿死亡率高,因此迫切需要一种简便易行、对母子无损的监护方法。胎盘是胎儿的器官其成熟过程随胎儿发育成长,理论上讲,胎盘的变化随妊高症的病情有所改变,并应根据胎盘的超微结构、显微镜下的改变以及大体形态学改变、影像学改变,进一步了解疾病对胎儿的影响。本文以B超声胎盘分级对妊高症的监护作用作了进一步观察。
As the causes of pregnancy-induced hypertension is unknown, but the threat to mother and child, maternal complications and high perinatal mortality, so there is an urgent need for an easy and safe, non-destructive mother and child guardianship method. The placenta is the organ of the fetus its maturation process with the growth and development of the fetus, in theory, changes in the placenta with pregnancy-induced hypertension has changed, and should be based on the ultrastructure of the placenta, microscopic changes and gross morphological changes, Learning to change, learn more about the impact of the disease on the fetus. In this paper, B ultrasound placental grading on the role of pregnancy-induced hypertension was further observed.
