What is the reason for premature rupture of membranes during pregnancy?

Lingling, a 24-year-old expectant mother in Tianjin, is now six months pregnant. Two days ago, she found that her vagina discharged some liquid, and then she went to Tianjin Kunru Mary Maternity Hospital for examination, and was diagnosed as premature rupture of membranes by doctors. At present, although her condition has been effectively controlled, she still wants to consult relevant experts. What is the cause of premature rupture of membranes? What is the impact of premature rupture of membranes on pregnant women and fetuses? Tianjin Mary Obstetrician Analysis: Under normal circumstances, premature rupture of membranes means that some pregnant women will suddenly have vaginal discharge, and the amount of discharge can be more or less, and these discharges are continuous, but the duration is uncertain, sometimes fast and sometimes slow. At present, the causes of premature rupture of membranes can be roughly divided into the following five aspects: 1. Sexual life: in the third trimester of pregnancy, the sensitivity of the uterus increases, and sexual life is easy to induce uterine contraction. Prostaglandin contained in semen can stimulate uterine contraction. During sexual life, the pregnant woman's abdomen may be squeezed and collided, which will increase the pressure in the amniotic cavity and cause premature rupture of membranes. Therefore, sexual life is an important cause of premature rupture of membranes. 2. Genital tract inflammation: vaginitis, cervicitis and other reproductive system inflammation are easy to cause fetal membrane infection, which in turn leads to fetal membrane rupture. 3. The fetal position is not correct. 4. Unreasonable nutrition. 5. Other reasons. For example, severe cough, long-term constipation and lifting heavy items may all lead to a sudden increase in abdominal pressure of pregnant women and premature rupture of membranes. Premature rupture of membranes is the main factor of premature delivery, and premature infants are prone to die because of their immature development. Premature rupture of membranes caused by abnormal fetal position, pelvic stenosis and other reasons is prone to umbilical cord prolapse, which leads to umbilical cord blood flow occlusion, intrauterine hypoxia and threat to fetal life. In addition, premature rupture of membranes is also prone to secondary intrauterine infection. If the fetus inhales the infected amniotic fluid, it can cause pneumonia and uterine distress, and the newborn is prone to neonatal pneumonia after birth, which is also one of the important causes of premature death. At the same time, intrauterine infection caused by premature rupture of membranes is an important cause of puerperal infection. Once a woman discovers premature rupture of membranes during pregnancy, she should immediately take a supine position to prevent umbilical cord prolapse and seek medical treatment immediately.
