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.

Premature rupture of membranes symptoms

Premature rupture of membranes refers to the rupture of the membranes before labor, and the symptoms of premature rupture of membranes include the following aspects: Firstly, a large amount of fluid will flow out of the vagina. Once the membranes rupture, amniotic fluid will flow out intermittently, releasing a colorless and odorless fluid, which will wet the underwear. Secondly, there may be a small amount of bleeding. When the membranes rupture, the capillaries at the edges of the membranes may bleed slightly, mixing with the amniotic fluid, resulting in some spotting or slight bleeding. Thirdly, there may be abdominal pain and the sensation of contractions. After the rupture of the membranes, this can stimulate the cervix, causing the release of inflammatory mediators from the cervix and inducing uterine contractions, leading to contractions and the sensation of abdominal pain. These are the symptoms of premature rupture of membranes.

Can you have a bowel movement if the membranes rupture early?

Premature rupture of membranes refers to the rupture of the amniotic sac before the onset of labor. After the premature rupture of membranes, amniotic fluid continuously leaks out, and there is a possibility of complications such as umbilical cord prolapse, placental abruption, and fetal intrauterine hypoxia. After the premature rupture of membranes, whether it is immediate delivery or treatment to prolong the pregnancy, the patient generally must not engage in out-of-bed activities. It is necessary for women with premature rupture of membranes to rest in bed, and one of the most important requirements is to manage urination and defecation while in bed. Although using a bedpan is uncomfortable and many women find it hard to adapt, it is unavoidable. This is because standing after the rupture of membranes can lead to excessive loss of amniotic fluid and increase the risk of umbilical cord prolapse and placental abruption; therefore, it is necessary to use a bedpan for bowel movements while remaining in bed.

Can premature rupture of membranes heal?

Premature rupture of membranes refers to the rupture of the membranes before labor, causing the leakage of amniotic fluid. In clinical practice, once premature rupture of membranes is confirmed, it is impossible for the membranes to heal again, as currently, there are no methods available to repair or suture the membranes. The treatment for premature rupture of membranes mainly involves preserving the pregnancy, suppressing contractions, and anti-infection therapy, without any expectation of curing the condition by healing the ruptured membranes. Once ruptured, the membranes cannot be healed again. Some patients, after experiencing premature rupture of membranes, may suddenly find that they are no longer leaking amniotic fluid and believe that it has healed. This scenario could be possible for several reasons: the first is that premature rupture of membranes may have not occurred in the first place, and the previous vaginal discharge could have been vaginal secretions; the second is that the amniotic fluid volume might be very low, with little amniotic fluid leaking out, which is a dangerous situation that requires prompt termination of the pregnancy.

Premature rupture of membranes causes

Premature rupture of membranes is a common complication during pregnancy, which can easily lead to intrauterine infection of the fetus and preterm delivery. The main causes of premature rupture of membranes include the following aspects: First, the most common cause is an infection in the vagina, which then leads to an ascending infection, triggering chorioamnionitis. When chorioamnionitis occurs, the fragility of the membranes increases, making them prone to rupture, leading to the leakage of amniotic fluid. Second, the membranes can rupture due to a blunt impact on the abdomen, such as an accidental strong hit, which can cause the membranes to suddenly break, leading to premature rupture of membranes. Third, an excessive amount of amniotic fluid, due to various reasons, can increase the pressure inside the amniotic cavity, potentially leading to spontaneous rupture of the membranes. These are the various reasons for premature rupture of membranes.

How is premature rupture of membranes diagnosed?

Premature rupture of membranes refers to the rupture of the membranes before the onset of labor, followed by the leakage of amniotic fluid. It is necessary to distinguish premature rupture of membranes from increased vaginal discharge and urinary incontinence. The methods to diagnose premature rupture of membranes include the following aspects: First, symptomatically, after the rupture of membranes, a clear liquid intermittently leaks from the vagina, accompanied by mild abdominal pain or bloody show. Second, after the rupture of membranes, the liquid leaking from the vagina can be tested with pH paper, which in most cases will change color, confirming the diagnosis of premature rupture of membranes. Third, an ultrasound can be used to observe a reduction in the amount of amniotic fluid within the amniotic cavity. Fourth, the leaking fluid can be examined under a microscope to observe "fern-like" crystallization, which can also confirm the diagnosis of premature rupture of membranes.
