Normal time of rupture of membranes during labor

When the amniotic fluid breaks, the pregnant woman herself feels vaginal discharge. Premature placental abruption before 37 weeks is called premature placenta. Preterm placental abruption is one of the key causes of premature birth. The sooner the amniotic fluid breaks, the worse the prognosis. Babies conceived below 24 weeks have a low chance of survival and induced abortion is recommended. For pregnant women over 37 weeks, the treatment plan should be decided based on whether there is fetal distress, placental abruption, umbilical cord prolapse, etc. If the amniotic fluid ruptures for more than 12 hours, antibiotics should be given to prevent infection.

Rupture of amniotic fluid is divided into normal rupture of amniotic fluid, that is, rupture of amniotic fluid caused by increased uterine cavity pressure before and after delivery, and placental abruption. Placental abruption refers to rupture of amniotic fluid that occurs before the announcement of delivery. Placental abruption may cause premature birth or uterine cavity infection, as well as infection of the fetus and newborn. Therefore, once placental abruption occurs, it needs to be properly treated. Placental abruption is divided into pre-term placental abruption and full-term placental abruption. For full-term placental abruption after 37 weeks, induction of labor and labor surgery should be performed as soon as possible to prevent infection.

For premature placental abruption before 37 weeks, corresponding treatment should be carried out according to the actual gestational age of the pregnant woman. For placental abruption above 34 weeks, it is not recommended to maintain the pregnancy, and the pregnancy should be terminated as soon as possible, because the fetus's ability to survive is relatively strong at this time. For placental abruption within 34 weeks, 24-48 hours can be bought to promote fetal lung maturity, and the complications of premature babies will be relatively reduced.

Rupture of the amniotic fluid refers to the rupture of the amniotic fluid due to the increase in pressure in the uterine cavity. Women will suddenly and spontaneously have a large amount of amniotic fluid discharged from their vagina. In this case, the amniotic fluid ruptures naturally only when the cervix is ​​dilated 5-6cm in the first stage of labor, or when it is almost fully dilated. When the amniotic fluid ruptures, the fetal head position will slowly drop, and the cervix will open before natural delivery can be possible. If the amniotic fluid ruptures before the woman goes into labor, it is called placental abruption. When placental abruption occurs, the woman needs to lift her buttocks and listen to the fetal heart rate to make sure it is normal and there is no fetal distress, and observe temporarily first.
