sac occurs in the growth and development of the child.In medicine bag of waters called the amnion.From the earliest stages of pregnancy the fetal bladder begins to provide favorable conditions for a healthy and fulfilling life of a child in utero.Among the most important functions of membranes should be noted the production of amniotic fluid.This fluid fills the cavity of the amnion, performing vital functions for the full development of the fetus.It is from these waters is generated habitat first child, so once again to talk about their enormous value is not necessary.Amniotic fluid promotes a comfortable well-being of the child (by maintaining a stable temperature of 37 degrees and comfortable living conditions), providing the necessary protection (water becomes a barrier to the penetration of a child to a variety of microorganisms and external negative influences).
Isolation of amniotic fluid occurs constantly and evenly.For large volume of her pregnancy will increase, reaching a maximum value at
composition of amniotic fluid during pregnancy
Different stages of pregnancy are accompanied by changes in the amount and composition of the amniotic fluid.Its structure is complex and fickle character.The composition of the fluid includes fats, proteins, hormones, carbohydrates, vitamins, enzymes, carbon dioxide, trace elements, oxygen, immunoglobulins as antigens that determine blood type of the child and other substances.Additional liquid may be a product of the sebaceous glands (in particular, cereals vernix covering the body of the child), skin, hair and also substances from maternal blood.
maintain a constant exchange of substances between the fetus and the mother's amniotic fluid.Baby will urinate directly amniotic fluid - updating occurs every three hours, providing a kid-friendly composition.
Functions of amniotic fluid during pregnancy
amniotic waters allocated a huge role in fetal development and normal condition of the child.The entire period of gestation, from conception to birth themselves almost amniotic waters have an important function.Stop more attention to them.
Metabolism. child receives from a huge amount of amniotic fluid substances necessary for the full life of the child.The very same kid identifies waste products in a liquid, which will be updated regularly - is output through the excretory system of the female body.
Mechanical protection of the child. Amniotic water and bag of waters provide for the child protection from mechanical damage.Through it formed a kind of "safety cushion".Amniotic fluid also becomes a barrier to fusion of tissues and umbilical cord compression.Through the waters of the child is able to free movement - for its more intensive development.
Sterility: in the amniotic fluid is always maintained sterility, contributing to a perfectly clean environment.They provide protection for the child from getting infections or exposure.The whole period of pregnancy, fetal treatment is updated every three hours, always maintaining an optimal chemical composition.Continue this process will be up to the period of rupture of membranes - when after the appearance of a baby into the world flow back water.
participation in childbirth. Amniotic fluid is given great importance, not only during pregnancy but also during childbirth.The outpouring of the front table (located at the bottom of membranes), and is the beginning of labor.Under their action there is a pressure on the cervix, which begins to unfold.Thanks amniotic waters maintained favorable conditions for the child during labor.During the outpouring of this water will wash the birth of water - to facilitate the promotion of the child for him.
Diagnostic value of amniotic fluid during pregnancy
amniotic fluid peculiar to important information on the current status, the conditions of development of the child.Including the importance given to the composition, volume, consistency, transparency and color of amniotic fluid - relevant data determined by the results of laboratory tests.Through analysis of fetal treatment may be identified sex and blood of the child, time to identify hereditary diseases, hypoxia, metabolic disorders.
If there is suspicion of pathology, genetic disorders or abnormalities of the child, recommended for pregnant women amniocentesis - to confirm the normal state of the child.
The composition of the amniotic fluid can be detected by the willingness of the child to the birth of that may require extra labor - including mounted the stage of maturity of the lungs and the respiratory system of the baby.
Pathology amniotic fluid during pregnancy
to ensure safe conditions for the development of the child shall be a certain condition and the amount of amniotic fluid.Indicate the presence of disease and disorders may be some changes in the chemical composition and amount of amniotic fluid:
Polyhydramnios. sign polyhydramnios amniotic fluid volume becomes more than 1.5 liters.Doctors still can not ascertain the cause of this condition.Still called some possible reasons: cardiovascular disease, nephritis, intrauterine infections, diabetes, multiple pregnancy, fetal malformations, Rhesus-conflict pregnancy.Polyhydramnios usually detected within 2-3 trimesters of pregnancy.In a sudden development of polyhydramnios arises the need for urgent delivery.
water shortage. This pathology is less common, but also poses a threat to the child's condition, leading to negative consequences for its normal development.Quite often, water scarcity leads to premature births that occur with complications.The amount of amniotic fluid at oligohydramnios is not more than 500 ml.This condition is accompanied by a constant pain in the abdomen of women, which are activated when your baby move - thus slowing down the activity of the child.
Dripping water.Before birth themselves should preserve the integrity of membranes - a necessary condition for the survival of the child.The consequence of rupture of membranes becomes amniorrhea - goes into labor.Ideally, this process should be timely, in the timing of the expected delivery.In premature discharge of water goes into labor - so you need to seek emergency medical help at a hospital.You will need to urgently inform your doctor about the leak of water in the presence of such suspicions.Tear membranes in this case occurs in the upper side portion with Leaking small amounts of amniotic fluid from the hole.
green water. fetal water in the normal state are transparent, like ordinary water.But may be slightly darker at the end of pregnancy, with the appearance of whitish flakes in their composition - as the baby will "fade", left his skin epidermal cells, vellus hair lanugo, vernix.Such a state of amniotic fluid is regarded as normal - can provide favorable conditions for the development of the child.But in the case of lack of oxygen to the baby (fetal hypoxia condition) it is probable ejection reflex meconium from the rectum.Water in a similar situation become brown or green, indicating the danger to the child.

At revealing any of the states require medical assistance.Therefore, when the signs of these disorders need to immediately consult your gynecologist.For greater certainty should take into account the need for regular scheduled scans, do not forget about the directions in the survey.Condition monitoring of amniotic fluid is provided by CTG, ultrasound, blood test for Rh antibodies, intrauterine infections, TORCH-infections.
