Amniotic fluid, their composition and functions
Amniotic fluid are periconceptional bag (amnion), which entered the fruit and are a zone of communication between the body of a pregnant woman and the fetus. The main function of membranes is that they provide the metabolism
Improves metabolism and losing weight without dieting
between mother and child (and hence the growth and development of the child), and saves the child from injury (in the second half of pregnancy, the fetus becomes mobile). During birth the amniotic fluid under pressure to the cervix, and contribute to its disclosure.
The composition of amniotic fluid is constantly changing, they contain protein, free amino acids, urea, steroid hormones, human chorionic gonadotropin (the hormone of pregnancy), minerals (sodium, chlorine, potassium, phosphorus, calcium), vitamins (A, C, group B), enzymes.
In the first one, 5 months of pregnancy the amount of amniotic fluid is 5 ml, then gradually increases and two weeks before birth equals 1-1, 5 liters. In the past two weeks, the amount of amniotic fluid is reduced to 600 ml. If the amniotic fluid less than normal, it is called oligohydramnios more - polyhydramnios.
What causes water scarcity and what it can lead
Water shortage may occur after an infection (especially viral), in the presence of a pregnant woman of chronic diseases (especially infections of the genital organs), metabolic disorders
Metabolism: The basis of life of all living things
, Endocrine disorders at different intoxication (nicotine, alcohol, drugs, certain medications, chemicals), with late toxicosis of pregnancy. All this contributes to the fact that violated the metabolic processes between mother and child, and this in turn leads to intrauterine growth and development of the child.
In the second half of pregnancy, the fetus begins to move actively, so the lack of amniotic fluid may be the cause of his injury, he may develop changes in the musculoskeletal system (spine, hip). When the amount of amniotic fluid is below normal possible merging of the fruit ookoloplodnym bag, which entails the formation of the fetus malformations. About half of pregnant women with oligohydramnios have threatened miscarriage. Often also begin preterm labor, where the weakness of labor.
How does water scarcity
Water scarcity may be mild or severe. In marked oligohydramnios pregnant women worried aching pain in the abdomen
Abdominal pain: when to sound the alarm?
Nausea - there may be problems with the nervous system
, Dry mouth and fatigue. The child begins to suffer from lack of oxygen, which is particularly affecting the development of the central nervous system, so often for health reasons such women performed caesarean section.
But the child is suffering and moderate oligohydramnios, often he is born with low birth weight and some developmental disabilities. Therefore, we must pay attention to the appearance of abdominal pain when moving the child and inform your doctor.
What is the basis diagnosed oligohydramnios
The amount of amniotic fluid is determined with ultrasound by calculating the specially developed index (amniotic fluid index - AFI), which allows to approach to the calculation of the amniotic fluid individually.
Since water scarcity may give various complications of the fetus, since its presence is confirmed by ultrasound, performed cardiotocography - synchronous recording fetal heart and uterine contractions, which allows you to judge the state of the child.
In addition, an ultrasound Doppler study of blood flow in the arteries of the uterus, umbilical cord and brain of the fetus, which gives the most complete information about the child.
Treatment of water scarcity
If oligohydramnios is primarily trying to identify the cause and treat the underlying disease that led to the dry years. In addition, prescribed drugs that improve placental circulation, metabolism in the placenta, fetal oxygen supply. Treatment is carried out under the control of ultrasound (including Doppler), and CTG. If the fetus is not improving, suffer the metabolic processes and the supply of oxygen the brain, then at 37 weeks gestation performed cesarean delivery.
Despite the fact that the vast majority of pregnancy with oligohydramnios out well, you should always remember that there are complications. Prevent complications can be only one way: regular prenatal visits, implementation of diagnostic studies and recommendations of the obstetrician-gynecologist.
