Premature rupture of membranes (PROM) refers to the rupture of the amniotic sac before the onset of labor, resulting in intermittent discharge of amniotic fluid from within the uterine cavity. PROM carries the following risks: Firstly, once rupture occurs, pathogens within the vagina can enter the uterine cavity through the cervix, easily leading to infections within the uterine cavity. Severe cases can cause maternal infections, leading to sepsis or septic shock. Secondly, an infection in the uterine cavity can easily cause fetal hypoxia in utero, or even stillbirth. Thirdly, when PROM occurs, the intermittent outflow of amniotic fluid can lead to prolapse of the umbilical cord. Fourthly, PROM can cause a decrease in the pressure within the uterine cavity, which may lead to the detachment of the placenta from the uterine wall, causing placental abruption.

Will the fetus still move if the membranes rupture prematurely?

Premature rupture of membranes refers to the rupture of membranes before labor, with amniotic fluid leaking intermittently. Based on the timing of the rupture, it can be classified into term premature rupture of membranes and preterm premature rupture of membranes. Although amniotic fluid will leak after the membranes rupture, leading to a reduction in its volume, amniotic fluid continues to be produced. Therefore, the fetus will still continue to move actively inside the uterus. In most cases, there is no abnormality in fetal movements after membrane rupture. However, if the membranes have been ruptured for a long time, or if the fetus experiences intrauterine hypoxia due to other factors, a decrease or absence of fetal movements may occur. Thus, normally, fetal movements continue after membrane rupture, but they may decrease or disappear if hypoxia occurs.

What fruits are good to eat when membranes rupture prematurely?

When premature rupture of membranes occurs, pregnant women can moderately consume some fruits that have a low sugar content. It is also important to eat fruit between meals in appropriate amounts, not excessively, as it might affect normal eating. Neutral fruits are recommended, including pomegranates, lemons, oranges, grapes, apples, olives, pineapples, and bananas, all of which are suitable to eat after premature rupture of membranes. Additionally, fruits such as kiwis, cherries, crabapples, and loquats can be consumed to supplement vitamins and folic acid. Fruits rich in Vitamin C such as tangerines, and also oranges and grapefruits, are also good options.

Can premature rupture of membranes recover?

Premature rupture of membranes cannot be reversed. This means that the patient's membranes rupture before labor begins, and the ruptured membranes cannot be restored to their original, unruptured state. When the membranes rupture, most patients will feel fluid leaking from the vagina, and the patient does not experience abdominal pain or any sensation of being about to give birth; this is referred to as premature rupture of membranes. Upon discovering this condition, the first step is to have the patient rest in bed, as this situation can easily lead to the exposure of the fetal umbilical cord, which can endanger the child's life.

Can premature rupture of membranes lead to a vaginal delivery?

If symptoms of premature rupture of membranes occur, further examination is still necessary to determine the specific mode of delivery. If there is only an early rupture of the membranes without systemic infectious symptoms, a comprehensive assessment of the development size of the fetus inside the uterine cavity, the specific amount of amniotic fluid, and the condition of the birth canal should be conducted. If there are no abnormalities, it is possible to attempt vaginal delivery. During the trial of labor, it is also necessary to closely monitor the changes in the amniotic fluid and the condition of the fetal heart rate. If any abnormalities occur, there is also the possibility of switching to an emergency cesarean section at any time.

What to do if the amniotic sac breaks early?

Premature rupture of membranes refers to the rupture of the membranes before labor begins. The management of premature rupture of membranes depends on the timing of the rupture and the condition of the fetus in the uterine cavity. First, for premature rupture of membranes after 34 weeks of pregnancy, since the gestational age is relatively advanced, the fetus is larger and more mature. In this case, the risks associated with continuing the pregnancy are higher. For premature rupture of membranes after 34 weeks, it is generally advised to allow natural progression or to deliver as soon as possible, and it is not recommended to attempt to prolong the pregnancy. Second, for premature rupture of membranes before 28 weeks of pregnancy, since the fetus is very small and the success rate of prolonging the pregnancy is relatively low under these circumstances, it is generally advised to terminate the pregnancy. Third, for premature rupture of membranes between 28 and 34 weeks, an attempt can be made to prolong the pregnancy as much as possible. However, if fetal hypoxia or infection occurs, the pregnancy should be terminated promptly.
