Premature rupture of membranes can be caused by a variety of reasons. Some are due to maternal malnutrition, the fetal membranes are thin and fragile, lack of elasticity, so easy to rupture; some are pregnant women’s cervix has lesions; there are also pregnant women’s abdomen by external forces and make the premature rupture of the fetal membranes, such as the abdomen by the impact of the abdominal or a history of abdominal compression sexual intercourse. However, in most cases, it is difficult to find a trigger for rupture of membranes. Premature rupture of membranes leads to the outflow of amniotic fluid, which is clinically manifested as running water in the lower body, which may be more or less. Since rupture of membranes is painless, many pregnant women tend to think that it is urination (when there is a lot of amniotic fluid) or leukorrhea (when there is little amniotic fluid). However, amniotic fluid is non-sticky, so it is different from sticky leukorrhea. Also, it is not difficult to distinguish it from urination because it flows more from the lower body in the standing position, decreases or stops flowing when lying down, and there is no urge to urinate. Rupture of fetal membranes can bring adverse effects to the mother and baby, and even cause serious consequences. Premature rupture of membranes is easily complicated by uterine infections, which can affect the fetus. Clinical data show that premature rupture of fetal membranes is prone to acute fetal membranitis, and the longer the rupture time, the greater the chance of infection. If the mother’s uterine cavity is infected, toxic shock may occur, endangering the mother’s life. If the infection affects the fetus, the fetus may suffer intrauterine distress or even die in the abdomen. If delivered, the abnormal incidence of neonatal asphyxia, neonatal pneumonia, sepsis and even neonatal death can be more than 50%. If premature rupture of membranes occurs due to fetal malposition, it is likely to cause prolapse of the umbilical cord, which interrupts fetal blood circulation and results in the premature death of the fetus. If it occurs before 37 weeks of gestation, it can lead to preterm labor and late miscarriage, and preterm babies are not only difficult to feed, but also prone to death. If the amniotic fluid runs out, it can lead to “dry labor”. At this time, the uterus is tightly wrapped around the fetus, affecting the blood circulation of the uterus and placenta. Insufficient blood supply to the fetus will easily cause intrauterine asphyxia, and will also cause uncoordinated contractions of the uterus, prolonging the labor process, increasing the rate of obstructed labor and the chance of cesarean section. Since most of the premature rupture of membranes occurs at home and mothers do not feel pain, mothers and their families often do not pay enough attention to it, thus delaying the diagnosis and treatment and bringing serious consequences. To prevent premature rupture of membranes, we must pay attention to the nutrition during pregnancy, pregnant women should eat more vegetables and fruits, and increase the intake of vitamin C. Emphasis on prenatal examination, found that the fetal position is not correct should be corrected as soon as possible. Those with pelvic stenosis should pay more attention. If there is severe cervical inflammation, it should be actively treated before pregnancy. Avoid heavy physical labor during the whole period of pregnancy, and prevent excessive fatigue. Attention should be paid to sexual life during pregnancy (sexual intercourse is prohibited for 3 months before and after pregnancy). It is also important to prevent trauma and shock to the abdomen. Once you notice “bedwetting”, you should seek medical attention immediately to prevent accidents.
