The absence of stomach pain after the water breaks at 38 weeks of pregnancy is most often the cause of premature rupture of membranes, which requires prompt hospitalization. Premature rupture of fetal membranes is a natural rupture of fetal membranes that occurs before labor, which may be accompanied by irregular abdominal pain or no abdominal pain, and is manifested by vaginal discharge that occurs suddenly and increases when abdominal pressure is increased. When water rupture occurs at 38 weeks of pregnancy, it is already a full-term premature rupture of membranes, which requires prompt hospitalization and a clear diagnosis through vaginal examination and ultrasonography, and prompt hospitalization. Since premature rupture of membranes increases the risk of uterine infection, when rupture of membranes occurs at 38 weeks of pregnancy, those who have surgical indications can terminate the pregnancy by surgery in a timely manner. If there is no clear indication for surgery, the doctor can fully assess the condition of the mother and fetus and then induce labor within 2 to 12 hours of rupture of membranes, and closely monitor the condition of the mother and fetus during the trial of labor to ensure the safety of the mother and fetus.
