If your water breaks at 30 weeks of pregnancy, you can’t keep the baby until full term, you need to terminate the pregnancy under the guidance of your doctor according to the condition of the mother and fetus. The water breakage at 30 weeks of pregnancy belongs to premature rupture of membranes, and you need to actively give dexamethasone to promote the maturation of the fetal lungs, as well as give antibiotics such as penicillin to prevent infection treatment under the guidance of the doctor. The fetal heartbeat is closely monitored, and blood and amniotic fluid levels are regularly reviewed. Because of the increased risk of infection after rupture of membranes, it is not possible to preserve the fetus until full term, and it is necessary to terminate the pregnancy in accordance with the maternal and fetal conditions at the appropriate time. Pregnant women should also pay attention to keeping the vulva clean and dry, disinfecting the perineum daily, reducing unnecessary vaginal examinations, and dynamically monitoring maternal temperature, contractions, maternal and child heart rates, and the amount and nature of vaginal fluid. In clinical practice, when there is a combination of fetal distress, chorioamnionitis and other serious complications, it is necessary to terminate the pregnancy in a timely manner, and to prepare for the rescue of the newborn.
