If the water breaks after 28 weeks of gestation, bed rest with elevated hips and dexamethasone injections should be given to promote fetal lung maturation. Anti-infective medication should be given 12 hours after the water breaks, and expectant treatment should be given until the contractions are complete. After delivery, intensive care is given in a timely manner to improve the survival rate of the preterm baby. If the water breaks before the 28th week of pregnancy, the existing medical measures may not allow the fetus to survive, so it is necessary to apply anti-inflammatory and contraction-suppressing drugs to prolong the pregnancy as long as possible, and if the symptoms of infection appear, the pregnancy can only be terminated by abortion. Therefore, after pregnancy, women must pay attention to proper rest, avoid trauma or pregnancy complications, and strengthen the maternity examination to avoid adverse effects on the fetus, so that women can safely pass the pregnancy period.
