Most women between 14 and 20 weeks of pregnancy are sent to a hospital; this occurs when a multiple pregnancy is already confirmed. In the article "Diagnosis of multiple pregnancies of uzi" you will find very useful information for yourself.
Possible complications
In multiple pregnancies complications are more common, therefore, usually an additional prenatal patronage is usually necessary. Some of the complications are associated with increased stress on the mother's metabolism, including:
• production of additional blood volume;
• more frequent and strong heartbeat;
• additional nutrient requirements.
Hypertension occurs in this case 2-3 times more often, and the probability of its early appearance is higher. Development of the fetus until about 32 weeks usually occurs in a similar way, as in a single pregnancy. Later this period increases the likelihood of disruption of development.
Specific tests
A blood test for the detection of Down syndrome is much less accurate in the case of twin pregnancy, but the risk can be assessed by ultrasound, which allows to see the thickening of the neck fold (collar space) of the fruit. These questions should be discussed at the first visit to the doctor. At a period of 18-20 weeks, a re-examination is usually performed to confirm the normal result. When the fetus has a common fetal bladder and placenta (monochorionic twins), there is a risk of a rare disease in which the pooling of blood vessels can lead to one fetus growing at the expense of the other (perinatal transfusion syndrome). Studies to identify such a pathology usually begin at 23-26 weeks.
Delivery
Approximately 1/3 of the twins are born before 37 weeks of pregnancy, and prematurity is one of the most likely risks in multiple pregnancies. The average duration of gestation by twins is 37 weeks, while triplets are born at 35 weeks, and the pregnancy with four fetuses lasts about 28 weeks after conception. Delivery in a multiple pregnancy is more likely to be performed by a caesarean section. By the end of the pregnancy, 10% of the twins are located, thus, the first fruit lies head down, and more than half of the second fruits also lie head down. It is safe enough to use pidular anesthesia in multiple births, and many midwives actively recommend it, as this provides very good anesthesia, in case additional help is needed. In general, the most important factor is the presentation of the first fetus. Even if there is a breech presentation of the second fetus, the delivery is natural enough safely. Head / breech presentation is approximately 25% of births. Sometimes a second twin will require obstetric intervention in childbirth or, possibly, cesarean section. Sometimes it is safe to give birth with two twins in the breech presentation in a natural way, but for a combination of the buttock / head, a caesarean section is usually recommended. Triple females and more twins are usually born by caesarean section. The risk of postpartum hemorrhage in multiple births increases.
