Causes of Premature Fetus Generally speaking, the causes of premature delivery mainly include the following two aspects:
Expectant mother's own reasons:
1. Repeated abortion: Repeated induced labor and abortion can cause cervical injury, especially in the second trimester, the cervical maturity is poor, which is more likely to cause cervical injury and lead to premature delivery due to dysfunction of the cervical internal orifice. At the same time, repeated abortion and induced labor can cause endometrial damage, lead to placental dysfunction, placental insufficiency, fetal distress, and increase the probability of iatrogenic premature delivery;
2, uterine lesions, uterine or cervical atresia, cervical surgery, this pregnancy has been operated;
3. Bad living habits, such as smoking, drinking, drug abuse during pregnancy, and excessive or strong unhealthy life;
4. Mental stress is too great. Due to work and life reasons, expectant mothers have too much psychological pressure, which will also lead to the production of related hormones, which will lead to uterine contraction and premature birth;
5. Expectant mothers suffer from acute infection and fever: such as cervical infection, vaginal infection, sexually transmitted diseases and other infections;
6. When the expectant mother suffers from pregnancy-induced hypertension, especially severe preeclampsia, uterine vasospasm leads to insufficient blood supply to the placenta, and placental dysfunction can lead to fetal distress. When conservative treatment fails, pregnancy can only be terminated;
7. There is no routine perinatal examination during pregnancy and lack of health care knowledge during pregnancy.
8. Estrogen and progesterone receptors are unbalanced.
9 pregnant women with medical and surgical complications, such as pregnancy complicated with heart failure, diabetes, anemia, appendicitis, etc. , has been premature.
Causes of placenta position:
1. In twin and multiple pregnancies, the uterus is excessively enlarged and the pressure in the amniotic cavity is high. Under the influence of unfavorable factors, premature rupture of membranes is more likely to occur and induce uterine contraction.
2. The fetus suffers from congenital diseases or is infected;
3, too much or too little amniotic fluid, premature rupture of membranes, chorioamnionitis;
4. Fetal malformation, fetal abnormality, stillbirth, etc.
How to prevent premature delivery is a great test for babies, parturients and their families. Therefore, preventing premature birth is the key to family happiness.
1. Pre-pregnancy detection of premature delivery related genes to determine whether to carry premature delivery susceptibility genes.
2. Those who have a history of premature delivery or family messengers can make a risk assessment of premature delivery first, such as the detection of fFN in vaginal secretions, inflammatory factors, tumor necrosis factor, cervical canal length and internal orifice, progesterone receptor, etc. after 27 weeks or even 24 weeks of pregnancy.
3. Do prenatal and perinatal examinations regularly, so as to achieve early detection, early diagnosis and early treatment, and seize the opportunity to extend pregnancy. Have a history of premature birth or family envoy to see a doctor 2 weeks earlier than the previous premature birth.
4. Develop good living habits, avoid contact with alcohol and tobacco during pregnancy, eat less spicy food, and eat less cold food such as seafood.
5. Avoid excessive physical activity during pregnancy, reduce the pressure of work and life, pay attention to rest and keep a happy mood.
