amniotic fluid leukocytes

Amniotic fluid protects the fetus during pregnancy and protects the mother. White blood cell examination in amniotic fluid can be used as an indicator of whether or not there is amnion chorioamnionitis. Basic Information Specialist classification: maternity check check classification: biochemical examination Applicable gender: whether women are fasting: not fasting Analysis results: Below normal: Normal value: no Above normal: negative: There are no white blood cells or negative at normal. Positive: Positive for amniotic chorioamnionitis. Tips: Amniocentesis is usually performed in the second trimester (16-21 weeks of gestation). Normal value Negative: no white blood cells. Clinical significance Positive: amnion chorioamnionitis. Positive results may be diseases: amnion infection syndrome considerations Amniocentesis is usually performed in 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. Specimens should be sent immediately after collection, and the results are significantly reduced due to exposure to sunlight. Inspection process Amniotic fluid specimen collection: Preoperative pregnant women should empty the urine, hands akimbo, 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. Detection method: using the principle of microscope optical fluoroscopy imaging, take 1 drop of physiological saline on the slide and add amniotic fluid evenly, then smear microscopy. Not suitable for the crowd 1, amniocentesis is generally performed in the second trimester (pregnancy 16-21 weeks), early pregnancy, late are not suitable. 2. Pregnant women do not take a cold. 3, the pre-operative need to obtain the consent of pregnant women and their families, those who do not check the indications should not be carried out. Adverse reactions and risks 1, maternal injury: puncture needle stab wound blood vessels caused by abdominal wall hematoma uterine subserosal hematoma. Occasionally, amniotic fluid enters the maternal blood circulation from the puncture hole and causes amniotic fluid embolism. The bladder was not emptied before the puncture, and the bladder was injured. 2, damage to the fetus, placenta and umbilical cord: puncture needle damage to the fetus can occur bleeding, stab wounds and umbilical cord can also occur bleeding or hematoma. Therefore, the source of bleeding should be identified when taking hemorrhagic amniotic fluid. If you suspect that you are from a fetus, you should continue to listen to the fetal heart. 3, amniotic fluid leakage: postoperative amniotic fluid leakage from the needle hole, resulting in too little amniotic fluid, affecting fetal development, and even cause miscarriage or premature birth. 4, abortion or premature delivery: the incidence of abortion or premature birth 0.1% -0.2%, often occurred within one week after surgery, even after the puncture, premature rupture of membranes leading to premature delivery. 5, intrauterine infection: postpartum may have maternal fever. Intrauterine infection can cause abnormal fetal development, or even fetal death. Therefore, amniocentesis should be strictly aseptic.
