In general, after premature rupture of membranes, there is still a significant risk of intrauterine infection. Normally, after premature rupture of membranes, it is necessary to clearly determine whether the development size of the embryo inside the uterine cavity is mature, as well as the specific amount of premature rupture of membranes and vaginal discharge. If the rupture of membranes is severe and there is a large amount of amniotic fluid flowing out of the vagina, it generally may lead to a reduction in amniotic fluid and significantly increase the risk of infection. After confirming premature rupture of membranes, it is necessary to actively use antibiotics for symptomatic treatment to prevent infections, promote fetal lung maturity inside the uterine cavity, and reduce the risk of delayed lung function development in the fetus after childbirth.

Premature rupture of membranes requires what examinations?

To diagnose premature rupture of membranes, first, a pH test of the vaginal fluid must be conducted. The normal pH value of vaginal fluid in women ranges from 4.5 to 5.5, whereas the pH of amniotic fluid ranges from 7.0 to 7.5. If the membranes have ruptured prematurely, the pH value would be greater than 6.5. Additionally, a smear test of the vaginal fluid can be done by placing vaginal secretions under a glass slide and examining them under a microscope. If fern-like crystals are observed, this indicates the presence of amniotic fluid. Furthermore, an ultrasound examination can be conducted. If the ultrasound shows a rapid decrease in the amount of amniotic fluid, this can assist in the diagnosis.

Does premature rupture of membranes require induction of labor?

The management of premature rupture of membranes varies depending on the gestational age. If the rupture occurs very early in pregnancy, the doctor will assess the maturity of the fetus. If it seems that the child still has a long way to mature, or it is difficult to conservatively maintain the pregnancy until maturity, induction of labor may be recommended. If the doctor feels that the fetus is mature enough, then induction of labor may be considered, which involves the administration of drugs to induce labor. If it is between these two scenarios, expectant management may be advised, which involves not inducing labor, along with infection prevention, bed rest, etc. Since infection can occur after a long duration of membrane rupture, it is important to closely monitor infection indicators during this period. If an infection is detected, labor may be induced using drugs to expedite delivery.

Premature rupture of membranes causes and symptoms

The symptoms of premature rupture of membranes include the following aspects: First, the most important symptom is the intermittent discharge of clear fluid from the vagina, which is often the most typical symptom of premature rupture of membranes. Second, abdominal pain can occur, as the rupture of the membranes can stimulate contractions causing pain. Third, sometimes there may be a small amount of spotting, mainly due to a small amount of bleeding caused when the membranes rupture. The causes of premature rupture of membranes include the following aspects: First, excessive amniotic fluid can cause high pressure inside the amniotic cavity, which may sometimes lead to spontaneous rupture of the membranes. Second, if there is local inflammation, such as chorioamnionitis, it can also cause the membranes to rupture under severe conditions, leading to premature rupture of membranes.

Can you walk with premature rupture of membranes?

In general, if premature rupture of membranes has already occurred, it is normally necessary to rest, avoiding standing and walking. Premature rupture of membranes mainly refers to the situation where the water breaks before the onset of labor pains. This means that the membranes have ruptured and amniotic fluid may leak out at any time. Standing or walking can easily lead to continuous leakage of amniotic fluid, resulting in a reduction of the fluid or prolapse of the umbilical cord due to the leakage. If the prolapsed umbilical cord causes compressive symptoms, the fetus can quickly die within the uterine cavity. Therefore, after confirming premature rupture of membranes, it is necessary to rest in bed with the buttocks elevated and closely monitor specific fetal heart changes.

Premature rupture of membranes' impact on the fetus

Premature rupture of membranes (PROM) refers to the rupture of the amniotic sac before the onset of labor, primarily affecting the fetus in the following ways. First, PROM can easily lead to premature birth, which may cause immature development of the fetus, often requiring treatment in neonatology. Second, PROM can lead to infections within the uterine cavity, subsequently causing newborn infections that can lead to neonatal death. Third, during the treatment of PROM, complications such as placental abruption or umbilical cord prolapse may occur, which can easily cause intrauterine hypoxia or death of the fetus. For PROM, it is essential to undergo proper treatment and monitoring. If any abnormalities arise, it is crucial to terminate the pregnancy promptly.
