Prenatal knowledge

Pregnancy is a very difficult process which not only brings inconvenience to women's daily life, but also may cause unexpected pregnancy accidents at any time. Therefore, from pregnancy to delivery, never be careless.

At ordinary times we have all heard of the loss of amniotic fluid, but very little has been heard about premature rupture of membranes. What exactly is premature rupture of membranes? Does premature rupture of membranes cause self healing? Let's get down to details.

Premature rupture of membranes self-healing probability?

First, what is premature rupture of fetal membranes?

Premature rupture of membranes refers to rupture of the fetal membranes before labor. Premature rupture of membranes at gestational age less than 37 weeks of gestation is also known as preterm (preterm) premature rupture of membranes. Premature rupture of membranes is the most common complication during perinatal period, which can lead to an increase in the rate of premature birth, an increase in perinatal mortality, and an increase in intrauterine infection rates and puerperal infections.

The common symptoms of premature rupture of membranes are: sudden discharge of the vagina and drainage of the fluid. The drainage is usually persistent, duration varies, the volume starts, then gradually decreases, a small number of intermittent drainage, vaginal discharge usually associated with maternal posture changes, activities or not.

Two, premature rupture of membranes self-healing probability?

Premature rupture of membranes is not self-healing, that is, premature rupture of membranes self-healing probability is zero. Premature rupture of the membranes is like a side of the bag. Once it has a small hole, the amniotic fluid and placenta will flow out at any moment.

If the rupture of membranes in the 28 weeks before the baby is very dangerous, if the rupture of membranes in 28 weeks later, the water is not too much to look forward to therapy, but once there are signs of infection or amniotic fluid can only rarely timely termination of pregnancy, the number of weeks of pregnancy the fetus, the survival rate is high.

Three, the reasons for premature rupture of membranes

1. intrauterine pressure abnormal intrauterine pressure were not common in cephalopelvic disproportion and abnormal fetal position; intrauterine excessive pressure is common in twin pregnancy, polyhydramnios, severe cough and difficulty in defecation.

2. trauma and mechanical stimuli are mainly divided into 2 categories: iatrogenic and non iatrogenic. Non iatrogenic, common late pregnancy sexual intercourse; medical sources include multiple amniocentesis, multiple vaginal examinations, and film stripping induction.

3., fetal membrane dysplasia: in addition to the factors of the fetal membrane itself, early pregnancy, maternal vitamin C deficiency, copper deficiency and smoking in pregnant women can lead to the development of fetal membranes. Lack of maternal nutrition, vitamin C, D and amino sugar (amniotic cell interstitial components) deficiency, can increase the brittleness of fetal membranes and lead to premature rupture of fetal membranes. If the lack of copper, zinc and other trace elements, resulting in brittle fetal membranes, lack of flexibility, easily lead to premature rupture of fetal membranes.

4. cervical insufficiency: in the non pregnant state, cervix mouth can expand without resistance to No. 8 to the diagnosis of cervical insufficiency cervical insufficiency mainly including relaxation of mouth and isthmus defect.

5., genital tract inflammation: vaginitis, cervicitis, easily lead to infection of fetal membranes, leading to rupture of fetal membranes. The pathogens causing the infection of the membranes are complicated. There are bacteria, mycoplasma and chlamydia, especially mycoplasma and Chlamydia infection. There are no obvious symptoms, and it is difficult for mothers to find them.

Four, how to prevent premature rupture of fetal membranes?

1. regular antenatal examination, found that pregnancy complications after treatment in a timely manner: malposition especially mothers can narrow pelvic treatment in pregnancy 4 to 5 months. If the cervix of the mouth is loose, then you can have a cervical cerclage at fourteen to sixteen weeks of pregnancy and rest on the bed after the operation.

2., strengthen education on contraceptive knowledge and reduce the rate of miscarriage, thereby protecting women. Pregnant women should understand whether they have gynecological diseases and do a good job of preventing reproductive infections.

3., expectant mothers should eat more vegetables to supplement vitamins, but also eat more nuts, wheat, seafood and other foods rich in copper to supplement the trace elements; also can be guided by the doctor to take vitamins and trace elements. In addition, expectant mothers should not be nervous and irritable and should maintain a calm state of mind and avoid premature delivery.

4., do not exercise for a long time, walk carefully also fall; in addition, because lifting heavy weight is easy to abdominal pressure, so avoid.

Note: three months before pregnancy, the fetus is unstable, the last month of pregnancy is also a dangerous period, so these two periods can not be in the same room, to avoid premature rupture of amniotic fluid.
