Premature Rupture of Membranes (PROM) occurs when the amniotic sac (membranes) breaks open prematurely before labor starts. When a PROM happens before 37 weeks of pregnancy, it is called a preterm premature rupture of membranes (PPROM).
It is estimated that 8-10% of pregnancies will be affected by PROM. Approximately 25%-35% of all preterm deliveries occur due to PPROM.
PROM may be due to a natural thinning of the membranes or the power of contractions. Infection of the uterine wall is a common cause of PPROM. Possible additional causes include:
Each pregnancy may present with slightly distinct symptoms. Those may consist of the following:
Diagnosing PROM can be done in several ways, including the following:
Based on the above evaluation, it can be hard to know if someone has PROM. Other tests could help figure out what's wrong.
If the diagnosis is still not clear after a full checkup, ultrasound-guided application of indigo carmine dye can be used to see if the membrane has broken by seeing if the dyed fluid has gone through the vaginal canal (using a tampon or pad). The membranes have broken if the blue dye shows up on the tampon or pad.
Symptoms, pregnancy, and health determine the treatment course. PROM's severity also matters.
In case of hospital admission, doctors and nurses will watch out for the following:
It is also possible to provide medications, including tocolytics and antibiotics. However, doctors may prescribe medication to induce labor. In other words, they may advise you to stop using tocolytics. Until a woman reaches week 34 of pregnancy, it is quite unlikely that she will be induced. In the event of complications, this may need to be done sooner. Such indications for delivery include the presence of chorioamnionitis and nonreassuring fetal status.
Furthermore, women with preterm PROM should be hospitalized and monitored regularly for complications such as infection, placental abruption, umbilical cord compression, fetal well-being, and labor.
Most cases of PPROM have an unknown cause. In the majority of pregnancies, this is not preventable.
It's very important to look after yourself while pregnant. This includes an early visit to the doctor once pregnancy is confirmed and regular checkups. Smoking should be stopped immediately, and ask a professional for advice. However, a study by Ghomian et al. (2013) found that if a woman has a history of PPROM, she may benefit from taking vitamin C supplements after the 14th week of pregnancy to prevent PPROM from recurring.
