Normal amniotic fluid color

I believe everyone knows that amniotic fluid is a substance that is very important for both the fetus and the pregnant woman. It has a good protective effect on both the fetus and the pregnant woman, and also provides sufficient living space for the fetus' growth and development. Amniotic fluid has certain colors, but if there is an adverse reaction, the color of the amniotic fluid will change. The following is a detailed introduction to the normal color of amniotic fluid.

The color of amniotic fluid changes as the pregnancy progresses. Before full term, the amniotic fluid is a colorless, clear liquid; at full term, due to the presence of vernix caseosa, small pieces of fetal skin cells, vellus, hair, etc. suspended in the fluid, the amniotic fluid becomes slightly milky white and mixed with white flocs. Once the amniotic fluid breaks, you have to go to the hospital to give birth, otherwise the baby will be in danger.

Clinical significance

(1) Yellow-green or dark green: fetal distress (meconium mixed in the amniotic fluid). (2) Reddish brown or brown: intrauterine fetal death (fetal death). (3) Golden yellow: The bilirubin level in the amniotic fluid is too high (incompatibility of maternal and fetal blood types). (4) Sticky and stringy yellow: post-term pregnancy, placental dysfunction. (5) Purulent or foul-smelling: intrauterine infection.

Precautions

Amniotic fluid examination is usually performed in the second trimester (16-21 weeks of pregnancy). Before the operation, you should empty your bladder, put your hands on your hips, and gently rotate your waist and abdomen. Then lie on your back, use B-type ultrasound diagnostic equipment to detect and locate, choose the puncture point, and perform the puncture under strict aseptic operating conditions. Generally, about 20 ml of amniotic fluid is drawn, placed in a clean and sterilized centrifuge tube, and sent for examination immediately.

Functions of amniotic fluid:

1 During the pregnancy, the amniotic fluid in the mother's belly plays a role in protecting the fetus. Although the big belly cannot avoid external pressure and impact, the amniotic fluid plays its role at this time. It can protect the baby in the belly from direct harm.

2 Moreover, the amniotic fluid provides the baby in the belly with space to move during the growth and development of the fetus, so that the baby in the mother's belly will not develop into deformities, because the amniotic fluid provides the baby with enough space to grow and develop well.

3 In addition to being beneficial to the fetus, amniotic fluid also plays a great role for the mother. Generally, the baby will move around in the mother's belly, but because of the effect of amniotic fluid, the mother will not feel any discomfort, thus protecting the mother.
