What Does It Depend On Pregnancy
The future baby receives oxygen and nutrients from my mother’s blood through the umbilical cord, which connects to the placenta, and that in turn is attached to the wall of the uterus. For the “supplies” to be uninterrupted, each link in this chain must regularly perform its function. Failure at any of the stages can lead to difficulties.
Uterus – Placenta
Impaired blood flow in the womb leads to disruption of the blood supply to the placenta, which causes the baby to receive less oxygen. The reason for this may be, for example, increased muscle tone of the uterus. She, like any muscular organ, can shrink throughout pregnancy, but the expectant mother feels it only with the approach of labor. If the muscles freeze in tension, “forgetting” to relax in time (for example, due to the pressure of excess amniotic fluid during high water), the blood vessels narrow and the blood flow in them slows down – which affects the supply of the placenta, and with it the baby. That is why this situation always attracts the attention of obstetricians because “unauthorized” contractions of a tense uterus can threaten the pregnancy.
To reduce the tone of the uterus and put oxygen to the baby, doctors can prescribe medications for relieving muscle spasm, antispasmodics; relaxing uterus muscles and suppressing its contractile activity – to colitis. And sometimes the situation can be solved by taking sedatives (sedatives) or vitamin-mineral preparations (for example, magnesium).
A great deal in the well-being of pregnancy also depends on the state of the endometrial lining of the uterus. If his condition is affected by inflammatory processes, infections (especially viral), curettage, the quality of the mucous membrane deteriorates and the blood vessels in it become smaller. At the conception stage, this can be manifested by the fact that a fertilized egg cannot correctly attach to the wall of the uterus — like a seed that can take root only in loose, fertile soil. And with the onset of pregnancy, the thinned mucous will not provide normal conditions for the placenta. As a result, it may be worse supplied with blood and transfer less oxygen to the baby.
Placenta – Umbilical Cord
A baby seat, also called the placenta, is the most critical battery that provides the baby with everything necessary for life. Violations of the structure and functioning of the placenta (placental insufficiency) or premature detachment of this organ inevitably lead to a decrease in blood flow in its vessels and impede the metabolism. The same happens in a situation where the placenta is incorrectly attached (in the lower part of the uterus, near the cervix) or is aging prematurely (before the 32nd week). In the latter case, its structure changes, the vessels narrow, the proportion of connective tissue increases, the blood supply decreases, and asphyxia in the unborn child becomes the result.
The Umbilical Cord – The Fruit
The umbilical cord connects the placenta and the unborn child. Inside it passes a vein through which blood, rich in oxygen and nutrients, flow from mother to baby and two arteries that bring the blood out of the baby’s body, saturated with carbon dioxide and metabolic products. Any pathology of the umbilical cord may impede the flow of blood to the unborn child. Its size is too large (more than 70 cm) or small (less than 40 cm), due to excessive length of the nodes, underdevelopment of the umbilical cord, improper attachment (not to the placenta, but to the fetal membranes), the absence of one of the arteries – it all turns the deterioration of the “supply”.
A temporary interruption of oxygen can also occur for purely mechanical reasons – if a crumb, moving in my mother’s belly, held out the umbilical cord, or the woman herself accidentally made it, having turned badly. The baby immediately signals its problem with displeased movements, and often, if the mother stands on the other side, everything returns to normal. But the situation that future parents are most afraid of – the entanglement of the umbilical cord around the neck – rarely leads to problems during pregnancy. Negative involvement does not affect the well-being of the baby, but if it persists until childbirth, it can be an indication for a cesarean section. Otherwise, there is a risk that during movement along the birth canal the umbilical cord will be delayed. SERIOUS CONSEQUENCES
Whatever the causes of oxygen starvation in a baby, this situation requires immediate treatment. Acute asphyxia threatens to turn into asphyxia – stopping breathing, but chronic asphyxia affects the well-being of the little man. The longer it lasts, the worse it’s consequences. Due to the lack of “vital gas” all organs and systems, without exception, suffer, but above all – the brain. Its cells are particularly sensitive to oxygen deficiency. Given that the mind is the main link of the central nervous system responsible for the development of a child, it becomes clear why children who have undergone intrauterine asphyxia often face neurological problems: for example, delayed development of motor skills, convulsive states, disorders of muscle tone, etc.
Under The Control Of Mom
Insufficient oxygen supply can occur at any stage of pregnancy. However, women usually hear the diagnosis of fetal asphyxia in the II – III trimesters, when doctors can identify this condition. And approximately from the 18th week, when mom starts feeling the crumbs, she becomes the chief diagnostician. After all, if the baby does not have enough oxygen, the nature of his movement’s changes: to activate the blood flow and thus compensate for the lack of air, he begins to move more vigorously. Shocks can be so violent, and sometimes painful, that sometimes deprive a woman of sleep and rest. When the child doesn’t have enough forces for active movements, he calms down – then mother feels that the actions have become rare and barely noticeable. That is why any sudden changes in the motor activity of the baby is a reason to consult a doctor immediately.
Find And Neutralize
Specialists can even detect hypoxia without individual devices using a simple obstetric tube. With a lack of oxygen, the nature of the child’s heartbeat changes: his rhythm becomes more frequent or, on the contrary, slows down. This is easily heard by the doctor, putting the stethoscope to the belly of a woman. But to accurately establish the degree and causes of the problem, one cannot do without technology.
For diagnosis, obstetricians use cardiographs (CT), which evaluates the baby’s heartbeat and uterine contractions, and Dope hydrometry, which can be used to measure the blood flow velocity in the uterus, placenta, umbilical cord and brain of the child. In recent years, in many clinics, it has been possible to rent a portable CTG apparatus, which is essential primarily for women with poor outcomes of previous pregnancies. With the help of such a device, the expectant mother daily measure the child’s heartbeat and report the data to the doctor.
Ultrasound remains an indispensable diagnostic method. If the first two methods reveal the effects of asphyxia, then only an ultrasound can establish its cause, such as placental abrupt-ion or cord entanglement. The main question that doctors must solve with the help of diagnostics is whether it is possible to prolong the pregnancy, by what methods, when and how the baby will be born.
Doctors do not treat the consequences, but the cause of asphyxia. And because in each case, the treatment will be unique. If the lack of oxygen has arisen due to the infection that the mother has encountered, then antiviral or antibacterial drugs will be required. With increased uterine tone, doctors will prescribe, for example, a means of relieving spasm. With placental insufficiency will improve the nutrition of the uterus, including with the help of special vitamin preparations.
