Preterm Premature Rupture of Membranes (PPROM): Understanding the Risks and Management
Preterm Premature Rupture of Membranes (PPROM) is a pregnancy complication that occurs in approximately 1% of all births, with the majority of cases taking place within the next seven days. According to a study, term Preterm Rupture of Membranes (PROM) occurs in around 8% of all pregnancies, and the outcomes for these cases are generally favourable.
PPROM occurs when the amniotic sac, which contains amniotic fluids that protect the fetus during pregnancy, ruptures prematurely. The signs of PPROM include a sudden gush or continuous leakage of clear or pale fluid from the vagina before 37 weeks gestation.
PPROM carries significant risks such as infection and prematurity-associated complications. Maternal risks include infection such as chorioamnionitis, which can have significant complications. Fetal/neonatal risks include preterm delivery leading to complications of prematurity, pulmonary hypoplasia, deformities due to mechanical restriction from oligohydramnios, increased risk of fetal loss or death, and morbidity related to extreme prematurity such as cerebral palsy.
The management and outcomes of PPROM depend heavily on gestational age and the latency period between rupture and delivery. Many pregnancies deliver shortly after PPROM, often within 28 days of membrane rupture. For early PPROM (< 34 weeks), expectant management may be pursued to prolong pregnancy, including antibiotics to prevent infection, corticosteroids to mature fetal lungs, tocolytics to delay labor, and close monitoring of mother and fetus. Late PPROM (34–36+ weeks) may be managed by either expectant or immediate delivery depending on clinical conditions.
If a person's water breaks before 37 weeks, they may need to be hospitalized for close monitoring. During expectant management, doctors will monitor vitals and counsel the pregnant person on progress and potential next steps. If a person tests positive for a group B Streptococcus (GBS) infection, they will need to go to the hospital immediately following their water breaking.
When membranes rupture at term, most pregnant people go into labor within 12 hours of their water breaking. However, the American College of Obstetricians and Gynecologists (ACOG) recommends waiting no longer than 24 hours before inducing labor in people who have their waters break at term. A doctor may use medications like prostaglandins and oxytocin, or devices such as laminaria or catheters with balloons, to induce labor.
In low-risk pregnancies, expectant management (waiting to see if labor starts independently) may be an option before induction. However, the ACOG recommends labor induction for people who experience PROM after 37 weeks and plan on vaginal delivery.
It is important for pregnant people to contact their OB-GYN if their waters break and they have a history of fast labor, the fetus is not in the head-down position, the fetus is high in their pelvis, they have had a C-section delivery before, or they have GBS or are unsure of their GBS status. Pregnant people should also go directly to the hospital if they begin feeling unwell, hot, or feverish, the fluid draining changes color or develops a bad smell, they experience only a small, one-time gush of fluid, they feel or see something in their vaginal opening, or they suspect a prolapse of the umbilical cord.
In sum, PPROM is diagnosed primarily by history and confirmatory tests, and requires individualized management based on gestational age and clinical status to optimize maternal and neonatal outcomes.
- For a person with psoriatic arthritis or ankylosing spondylitis, the stress and discomfort of a migraine can be exacerbated during pregnancy, particularly in the trimester when symptoms are most prevalent.
- Science is working tirelessly on new predictive models that aim to detect risks of complications like PPROM in high-risk pregnancies, such as those associated with breast cancer or certain autoimmune disorders like psoriatic arthritis.
- Pfizer and other pharmaceutical companies are conducting ongoing research in the field of health-and-wellness, focusing on creating medications that can alleviate symptoms of various conditions, including arthritis and cancer treatments.
- Some scientific studies suggest that women who have experienced PPROM may be at an increased risk of developing autoimmune diseases like rheumatoid arthritis and psoriatic arthritis in the future.
- In order to have a healthier pregnancy, it's essential for women to maintain a balanced diet, regular exercise routine, and avoid blocked ducts or infections that could lead to complications like PPROM.
- For women dealing with fertility issues or those who are trying to conceive, staying informed about women's health concerns like PPROM can be vital in making informed decisions and taking proactive steps to maximize their chances of a successful pregnancy.
- By working closely with OB-GYNs, women can better understand the risks, signs, and management strategies for PPROM and other complications during pregnancy, improving the overall health and wellness of both mothers and babies.
