Births that occurred before the 37th week of pregnancy are considered premature, and in such cases specialized assistance is required, both for the baby and for the mother. Survival of premature babies with premature births at different times depends on the timely provision of care and the creation of appropriate conditions for nursing and further development of the newborn. Children are placed in a kuvez, in which the necessary temperature and humidity is maintained, feeding is done with a probe. To save the baby, with the threat of premature birth, doctors can be prescribed therapy to maintain pregnancy or to accelerate the development of the lungs of the child so that it can adapt in the extrauterine environment. A major role in the appointment of therapy and the preservation of pregnancy is the timely detection of abnormalities or disorders that can lead to miscarriage.
Why is this happening?
The causes of premature birth are due to various social, biological and genetic factors affecting the course of pregnancy and fetal development. The fact that stresses, malnutrition, acute infectious diseases, excessive physical activity and bad habits can adversely affect the development of the fetus is known to all. But there are hidden causes of miscarriage, such as pathological changes in the uterus, hormonal disorders, chronic diseases, not cured before the onset of pregnancy. Multiparty can cause overgrowth of the walls of the uterus, which also often calls for labor before the due date. For example, it is often noted the onset of premature births at the birth of twins or triplets. A too large fruit can also cause miscarriage.
When can delivery begin?
From the above factors, the timing of the onset of labor and the subsequent development of the child also depend.
Premature birth until 20-22 weeks are considered spontaneous miscarriage, the level of survival of newborns is very low. The most common cause is fetal developmental pathologies, infectious diseases or complications.
Premature births from 22 weeks are due to various factors, and in the absence of pathologies of fetal development or a threat to the life of the mother, doctors can attempt to prolong pregnancy.
The cause of premature birth until 24-27 weeks is most often istmiko-cervical insufficiency. In the risk group at this time, in the first place includes the recurrent. Isthmicocervical insufficiency occurs when the cervix is damaged, as a result of which it can not hold the fetal egg.
Premature birth at the 27th, 28-30th week is due to more diverse causes. Primordinates account for one-third of the total number of births on these dates. The reason for premature delivery at week 30 can be both internal disorders, and the impact of external factors. As a rule, at this time it is recommended to limit physical activity, if possible, emotional outbursts should be avoided. Survival in preterm birth at 27-30 weeks is higher than in earlier periods, nevertheless, the child needs special help and conditions for further development. Premature delivery at the 30-32 week is less frequent than in later terms.
Preterm delivery in 35-37 weeks is more than 50%, and the factors affecting early pregnancy at these terms are completely diverse.
To prevent premature birth, as a preventive goal, it is advisable to undergo a full examination before pregnancy or in early periods, for the timely detection of pathologies and infectious diseases. If the threat of miscarriage arose during pregnancy, it is necessary to closely monitor the condition, and when symptoms of premature birth appear, hospitalization is necessary. Signs of premature birth is the appearance of heaviness or pain in the lower abdomen, back pain, sudden changes in the motor activity of the fetus, secretions from the genital tract, regular contractions, the outflow of amniotic fluid. Contractions can not always accompany premature birth, for example, with ismiko-tsirvikalnoy insufficiency, birth can begin virtually asymptomatic.
If, in spite of all attempts to keep the pregnancy, premature birth comes, then it is necessary to find out the reason to avoid problems later, during subsequent pregnancy.
