Amniotic fluid is the internal environment for the survival of the fetus, which protects the fetus and acts as a cushion. The amount of amniotic fluid is an indicator of the well-being of the fetus in the uterus. Premature rupture of amniotic fluid may cause preterm labor, fetal distress, mother and child infection and other dangers. 1. Preterm labor: Premature rupture of amniotic fluid leads to a decrease in amniotic fluid in the uterine cavity, shrinking of the uterus and pressure on the fetus, which may cause preterm labor. 2. Fetal distress: premature rupture of amniotic fluid leads to excessive outflow of amniotic fluid, the volume of the uterine cavity becomes smaller, causing uncoordinated contractions of the uterus, which affects the labor process and blood circulation of the fetus, leading to fetal distress, and in severe cases, it may lead to the death of the fetus. 3. Maternal and infant infections: premature rupture of amniotic fluid leads to damage to the vaginal barrier, which can easily cause maternal infections such as puerperal infections, and can also increase the risk of fetal infections, causing aspiration pneumonia and so on. In the case of premature rupture of amniotic fluid, it is recommended that the patient go to the hospital for examination in a timely manner and take good care of the mother and baby to prevent the amniotic fluid from losing too fast and causing danger.
