When preterm premature rupture of membranes occurs, it can have certain impacts on both the pregnant woman and the fetus. The risks of preterm premature rupture of membranes primarily include the possibility of umbilical cord prolapse, preterm birth, or infection during pregnancy. If the presenting part of the fetus has not descended and the umbilical cord slips into the vagina, umbilical cord prolapse can easily occur, which is very dangerous and can lead to fetal hypoxia or even stillbirth. After the rupture of membranes, bacteria originally present in the vagina may take this opportunity to enter the uterus, causing chorioamnionitis or endometritis. If the infection is not controlled in time, sepsis may also occur.

Can an ultrasound detect premature rupture of membranes?

Premature rupture of membranes (PROM) refers to the rupture of amniotic fluid before labor. The most common diagnostic method for PROM is based on the clinical symptoms of the patient, mainly intermittent vaginal discharge. PROM can be confirmed using pH test strips specific for this condition. Ultrasound can be used as an auxiliary diagnostic method for PROM because most pregnant women with PROM will show a decreased amount of amniotic fluid during an ultrasound. However, the specificity of using ultrasound to determine PROM is not strong. Although the membranes may rupture, amniotic fluid can still be continuously produced, so some pregnant women may still have a normal amount of amniotic fluid during an ultrasound. Therefore, in most cases of PROM, a reduction in amniotic fluid can be observed through ultrasound, but there are cases where the amniotic fluid level appears normal. In such instances, it's essential to analyze the patient's clinical symptoms.

What are the risks of premature rupture of membranes?

After premature rupture of membranes, the amniotic cavity is directly connected to the woman's vagina at this time, which primarily poses the risk of infection. If the fetus becomes infected, it is easy to lead to sepsis after birth, resulting in an increased mortality rate for the fetus. Additionally, it can cause bleeding in the fetus. Moreover, for the mother, there is a likely risk of placental abruption, which is due to the reduced abdominal tension after membrane rupture, making placental abruption more likely to occur. Furthermore, the mother is also prone to infections, which can easily lead to chorioamnionitis under these circumstances.

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.

Premature rupture of membranes how is it shown on ultrasound?

Ultrasound is a commonly used auxiliary method for diagnosing premature rupture of membranes. After the membranes rupture prematurely, amniotic fluid intermittently leaks out from the uterine cavity, but the production of amniotic fluid often cannot keep up with the leakage. Therefore, the majority of pregnant women with premature rupture of membranes will experience a reduction in amniotic fluid volume. Ultrasound will reveal that there is still a small amount of amniotic fluid in the amniotic cavity, but the volume is much lower than the normal range; the maximum depth of the amniotic fluid should be less than three centimeters, and the amniotic fluid index should be less than eight centimeters, which is a common occurrence. However, sometimes, if not much amniotic fluid leaks out after premature rupture of membranes, the ultrasound may sometimes show that the amniotic fluid volume is normal. In such cases, it is necessary to combine this finding with the patient's clinical symptoms to jointly determine the presence of premature rupture of membranes.

Can you go to the bathroom if the membranes rupture early?

Premature rupture of membranes, as the name suggests, refers to the rupture of the amniotic sac before labor commences, leading to intermittent discharge of amniotic fluid from the uterine cavity. After the membranes rupture prematurely, whether choosing to deliver or attempting to prolong the pregnancy, bed rest is required, and one should not get up to use the toilet. If one needs to use the toilet, it must be done on the bed. Standing up to use the toilet like a normal person can bring about the following risks: 1. It can cause excessive loss of amniotic fluid, leading to low levels of amniotic fluid, which can cause fetal hypoxia in the uterus. 2. Standing up to use the toilet can lead to cord prolapse or placental abruption, which can cause acute fetal hypoxia within the uterine cavity. Therefore, with premature rupture of membranes, one should not stand up to use the toilet.
