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.

Premature rupture of membranes causes

The causes of premature rupture of membranes, or premature rupture of membranes, occur before labor when the membranes break. Normally, the membranes should rupture during labor when the cervix is fully dilated. Any rupture before this is called premature rupture of membranes. The main causes of premature rupture of membranes are maternal infections or cephalopelvic disproportion. Infections can cause the membranes to become fragile and thin, and movements afterwards may lead to premature rupture. Another scenario is cephalopelvic disproportion, where the fetus is relatively large and the pelvis is small, leading to changes in amniotic fluid pressure, which can also result in premature rupture of membranes.

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 can premature rupture of membranes be detected?

In the late stages of pregnancy, if abnormal vaginal discharge occurs, it is necessary to consider whether there has been premature rupture of membranes. The symptoms of premature rupture of membranes include abnormal vaginal discharge, which sometimes can be heavy and, at other times, may be less. It is often accompanied by a feeling of warmth, without any pain symptoms. If it is unclear whether the condition is due to premature rupture of membranes or urinary leakage, it is recommended to visit a hospital for examination. Doctors can distinguish between premature rupture of membranes and urinary leakage using pH paper, and sometimes further ultrasound examinations are needed to monitor the amniotic fluid volume, which can determine if there has been a premature rupture of membranes.

Premature rupture of membranes symptoms

Premature rupture of membranes, as the name implies, refers to the clinical symptoms caused by the rupture of the amniotic sac before labor. These symptoms include the following aspects. First, there will be a leakage of amniotic fluid from the vagina, manifesting as wet pants or a wet bedsheet, which is a primary indication of premature rupture of membranes. Second, when the membranes rupture prematurely, there is often a small amount of bloody show. This is mainly because there are small capillaries on the membranes that also bleed when the membranes rupture, causing blood to mix with the amniotic fluid. Third, premature rupture of membranes often is accompanied by significant contractions, as the increase in pressure within the amniotic cavity during contractions can cause the membranes to rupture. When these situations occur, it is important to promptly go to the hospital to undergo an ultrasound and gynecological examination to confirm whether there is a premature rupture of membranes.

Can premature rupture of membranes be detected by ultrasound?

Premature rupture of membranes refers to the rupture of the amniotic sac before labor begins. The diagnosis of premature rupture of membranes is mainly based on clinical symptoms, gynecological examination, and ultrasound assessment. Ultrasound can only serve as an auxiliary tool for diagnosing premature rupture of membranes. This is because, during premature rupture, an ultrasound might sometimes show a reduction in amniotic fluid due to significant fluid leakage, although amniotic fluid can also regenerate quickly. In such cases, an ultrasound done for premature rupture of membranes might still show the amniotic fluid level within the normal range. Therefore, the diagnosis of premature rupture of membranes heavily relies on clinical symptoms and gynecological examination. The presence of a large amount of fluid leaking from the vagina and a change in color on the amniotic fluid test strip during a gynecological examination are crucial for confirming the diagnosis. Ultrasound, in this context, serves only as a supplementary diagnostic method.
