Amniotic fluid: water, all of which came

Amniotic fluid Many women, especially those who are preparing to become a mother, about know what the amniotic fluid.But few of them have an idea of ​​what the amniotic fluid and amniotic fluid - it's the same thing.Amniotic fluid - this is the first environment in which the child lives.If you recall the evolution, all living organisms emerged from the water, and this law once again confirms the presence of amniotic fluid during pregnancy, where the baby develops.

amniotic fluid

amniotic fluid (amniotic fluid) - a biologically active environment that surrounds the fetus during pregnancy.Amniotic fluid is a clear, colorless, slightly hazy in the third trimester of pregnancy (due to the cells of the epidermis).Amniotic fluid perform a number of useful features:

  • protect the fetus from mechanical impact (injury blows abdomen);
  • prevent the cord from the infringement;
  • in childbirth contribute to the disclosure of the cervix;
  • protect the fetus from infection;
  • allow free movement of the fetus.

volume of amniotic fluid

Throughout the pregnancy the amniotic fluid volume changes.For example, at 10 weeks, he is only 30 ml at 14 weeks volume reaches 100 ml, and the maximum volume of amniotic fluid necessary for periods of weeks and 36-38 is 1000-1500 ml.Before birth the amount of amniotic fluid decreases somewhat.

Education amniotic fluid occurs due to the system "mother-placenta-fetus".Maternal body delivers plasma propotevayuschuyu of the vessels, the placenta produces a liquid membranes - the amnion, the fruit by the kidneys that produce urine (about 600-800 ml per day).Full update amniotic fluid occurs every three hours.

composition of the amniotic fluid

composition of the amniotic fluid is different at each stage of pregnancy.In the first trimester, it is a fluid similar to blood plasma.In the last weeks of pregnancy the amniotic fluid are represented mainly by the urine of the fetus.In addition, the amniotic fluid contains:

  • oxygen and carbon dioxide;
  • electrolytes;
  • epidermis and hair vellus fruit;
  • vernix fruit;
  • proteins, fats and carbohydrates;
  • hormones;
  • enzymes;
  • phospholipids and clotting factors;
  • vitamins.

study of amniotic fluid

diagnosis of amniotic fluid is carried out in the presence or suspicion of disease in the fetus.For the diagnosis of amniotic fluid is taken into account all the parameters: the number, composition, color, transparency and more.

Amniocentesis Amniocentesis - a piercing membranes for taking a small amount of amniotic fluid.Performed under ultrasound guidance.Special needle puncture the abdominal wall, the uterus and the fetal bladder.Possible complications: the threat of premature birth, bladder injury The bladder - structure and function Urinary bladder - structure and function mother and intestines, infection of the amniotic fluid, fetal vascular injury.Amniocentesis is performed in cases of: rhesus (increased bilirubin in the waters), suspicion of chromosomal and genetic abnormalities of the fetus, the suspicion of chronic oxygen deficiency of the fetus to determine fetal lung maturity.In addition, an amniocentesis to determine the blood type of the fetus and the amount of antibodies to the Rh factor.

  • amnioscopy

amnioscopy - a survey of membranes (water front) with the help of a special apparatus - amnioscopy.Amnioscopy woman entered into the cervical canal Cervical canal - the path traversed by every person Cervical canal - the path traversed by every person .Amnioscopy helps determine the color and the amount of amniotic fluid.For example, when fetal hypoxia fetal hypoxia - the consequences of lack of oxygen in the body Fetal Hypoxia - the consequences of lack of oxygen in the body water are green or greenish due to meconium (stool original).Normally, the child moves meconium after birth, when he departs oxygen deficiency in the amniotic fluid.

  • US

main task of US in respect of amniotic fluid - the definition of their number.We prove a direct correlation between the amount of amniotic fluid and pathology of pregnancy.For example, the amount of amniotic fluid decreases or increases in the post-term pregnancy, preeclampsia, and chronic fetal hypoxia Chronic fetal hypoxia - serious consequences Chronic fetal hypoxia - serious consequences and rhesus conflict.
