Introduction

Introduction Normal amniotic fluid in term pregnancy is slightly opaque and opaque. It can be seen that there is a small piece of amniotic fluid in the amniotic fluid. If the amniotic fluid is mixed with blood, it may be caused by placental abruption and some bleeding diseases, but some may not find the cause. Normal pregnancy amniotic fluid is slightly turbid and opaque, showing small pieces of amniotic fluid (fetal fat, fetal exfoliated epithelial cells, mane, hair, a small amount of white blood cells, albumin, urate, etc.), and amniotic fluid contains a large amount of hormones ( Including estriol, progesterone, cortisol, prostaglandin, HPL, HCG, etc.) and enzymes (such as lysozyme, lactate dehydrogenase, amylase, B-galactosidase, hexosaminidase A, etc. ).

Diagnosis and diagnosis of amniotic fluid:

It can be seen that there is a small piece in the amniotic fluid, if there is blood mixed in the amniotic fluid.

Diagnosis

Differential diagnosis

Identification of symptoms of amniotic fluid confusing:

Excessive amniotic fluid: the amount of amniotic fluid in normal pregnancy increases with the increase of gestational age, and gradually decreases gradually in the last 2 to 4 weeks. The amniotic fluid volume in the full-term pregnancy is about 1000ml (800-1200ml), and the amount of amniotic fluid exceeds during any period of pregnancy. 2000ml, called polyhydramnios. Up to 20,000ml. Most pregnant women have a slower increase in amniotic fluid, which is formed in a relatively long period of time, called chronic amniotic fluid; a few pregnant women have a sharp increase in amniotic fluid within a few days, called acute polyhydramnios. The incidence of polyhydramnios is reported in the literature as 0.5% to 1%, and the incidence of pregnancy with diabetes can reach 20%. When the amniotic fluid is too much, the appearance and traits of amniotic fluid are no different from those of normal people.

Amniotic fluid fecal dye: Amniotic fluid fecal dye refers to the relative hypoxia of the fetus in the uterus, causing the anus to relax, and the fetus is discharged into the amniotic fluid, causing amniotic fluid pollution.
