Causes of premature rupture of membranes

When symptoms such as premature rupture of amnion appear in our lives, we should be prepared for premature birth, because premature rupture of amnion can cause the pregnant woman's uterus to relax, and the fetus has begun to be born. At this time, problems such as poor development of the fetal membrane can cause the amniotic fluid to rupture. Therefore, it is recommended that pregnant women should not have sexual intercourse in the late pregnancy. Everyone should understand the dangers and causes of premature rupture of amniotic membranes.

reason

1. The cervix of the pregnant woman relaxes, which stimulates the fetal membrane and causes premature rupture of amniotic fluid.

2. Hypoplasia of the fetal membrane, such as the presence of amnion-chorioamnionitis, causes excessive pressure in the amniotic cavity, leading to premature rupture of membranes.

3. Malposition of the fetus, narrow pelvis, cephalopelvic disproportion, polyhydramnios, multiple pregnancy, etc. can all increase the pressure in the amniotic cavity and cause premature rupture of membranes.

4. Inadvertent sexual intercourse during pregnancy can cause amniotic-chorionic infection, especially the prostaglandins in semen can induce uterine contractions, resulting in uneven pressure in the amniotic cavity and causing premature rupture of membranes.

5. Some other factors can also cause premature rupture of membranes, such as severe coughing during pregnancy, sudden laughter or anger, and doing heavy physical work, which can cause a sharp increase in abdominal pressure, causing the fetal membrane to rupture and the amniotic fluid to flow out of the vagina.

harm

Premature birth

The fetal membrane is a protective membrane for the fetus. If the membrane ruptures prematurely, the amniotic fluid will flow out prematurely and lose its protective effect on the fetus. After the amniotic fluid flows out, the uterus will become smaller, which will constantly stimulate uterine contraction. If the fetus is not full-term at this time, premature birth will occur. The organs of premature babies are not fully developed, their weight is low, their living ability is poor, and they are very likely to die.

Intrauterine distress

If the water breaks before labor begins and the fetal presenting part is not determined, the umbilical cord will prolapse along with the amniotic fluid, causing distress to the fetus in the uterus.

Hypoxia

If too much amniotic fluid flows out, the uterus will stick close to the fetus's body, stimulating the uterus to cause uncoordinated uterine contractions, thereby affecting the progress of labor and placental blood circulation, leading to dystocia and fetal hypoxia.

Mother-to-child infection

The longer it takes for the membranes to rupture, the greater the chance of intrauterine infection. If the fetus inhales infected amniotic fluid, it can cause aspiration pneumonia. In addition, mothers are also prone to infection during delivery or postpartum infection.
