Amniotic fluid osmotic volume (pressure)

Amniotic fluid protects the fetus during pregnancy and protects the mother. The examination of amniotic fluid osmotic pressure can reflect the growth and maturity of the fetus in the uterus. Water tests are usually performed during the second trimester (16-21 weeks of gestation). The urine should be drained before surgery, with both hands on the hips and gently turn the waist and abdomen. Then supine, use B-ultrasound to detect the positioning, select the puncture point, and puncture under strict aseptic operation conditions. Generally, about 20 ml of amniotic fluid is taken and placed in a clean and sterilized centrifuge tube for immediate inspection. Basic Information Specialist classification: maternity check check classification: ultrasound Applicable gender: whether women are fasting: not fasting Tips: Amniocentesis is usually performed in the second trimester (16-21 weeks of gestation). Normal value Early pregnancy is equivalent to blood permeation (pressure). Full-term pregnancy 230 ~ 270mmol / L (230 ~ 270mOsm / L). Clinical significance ≤270mmol/L fetal maturity.
