When a woman’s water breaks during pregnancy and the baby’s head is not in the pelvis during obstetrics, it is possible for her to have a normal delivery. In this case, the doctor usually evaluates whether the pregnant woman has the conditions for a vaginal trial of labor. If it is possible to have a vaginal trial of labor, the pregnant woman may be given an intravenous drip of hysteronin, and the baby may be able to enter the pelvis smoothly under the contractions induced by the hysteronin, and then the labor may be carried out without obstruction. However, if cephalopelvic disproportion exists, early cesarean section is needed to terminate the pregnancy. During pregnancy, pregnant women should pay attention to rest, appropriate activities, pay attention to vulvar cleansing, pay attention to fetal movement, and undergo regular checkups; if water breaks, go to the hospital as soon as possible for checkups; and get out of bed as soon as possible after delivery to promote the discharge of bad dew.
