How long does it take to give birth after the amniotic fluid has broken, it needs to be analyzed by full-term and non-full-term rupture of membranes, usually it takes less time to complete the birth after full-term rupture of membranes, and longer time when it is not full-term. 1, full-term rupture of membranes: the fetus has reached the full term of pregnancy, i.e. gestational age > 37 weeks, usually the fetal membranes rupture about 12 hours to start labor and complete the birth within 24 hours. If labor is not in progress and there are no signs of infection, labor can be induced as appropriate; if labor has not started, antibiotics should be given to prevent infection, and if labor is not in progress 72 hours after rupture of membranes, it is recommended to perform a cesarean section to avoid intrauterine infection endangering the fetus; 2, premature rupture of membranes: usually it takes about 3 days to complete labor, first give fetal preservation treatment, such as the application of magnesium sulfate, nifedipine and other drugs to inhibit smooth muscle contraction, and strive to extend the gestational week. At the same time, check the maturity of the fetus, observe it closely, and according to the doctor’s judgment, apply glucocorticoids to promote fetal lung maturation at an appropriate time, which usually takes 2 days, after which the pregnancy can be terminated by medication or cesarean section. In addition, for fetuses less than 24 weeks of gestation, the survival rate is low due to incomplete organ development, so it is generally recommended to abandon the pregnancy. After the water breaks, it is important to maintain emotional stability, and the pregnant woman is advised to lie flat, raise her hips, do not walk frequently, and go to the hospital as soon as possible to avoid serious consequences such as cord prolapse and placental abruption, which can endanger the health of mother and baby.
