Childbirth involves numerous decisions, and understanding the procedures your care team might recommend is a key part of feeling informed and empowered during labor. One such procedure is artificial rupture of membranes (AROM), often called “breaking your water.”
While AROM is a routine practice in many births, it’s essential to understand what it involves, why it’s done, and the potential benefits and risks. This evidence-based guide will provide you with the information you need to make an informed decision about AROM and how it may fit into your birth plan.
What Is Artificial Rupture of Membranes (AROM)?
During pregnancy, the baby is surrounded by amniotic fluid inside the amniotic sac, a protective environment that cushions and supports the baby’s development. Typically, this sac breaks naturally at some point during labor—a moment often referred to as your “water breaking.”
AROM is a medical procedure where a healthcare provider manually breaks the amniotic sac using a sterile instrument, such as an amnihook or amnicot (a tool resembling a crochet hook). The procedure is usually quick and relatively painless, though it can feel slightly uncomfortable.
Why Is AROM Performed?
AROM is often used as a tool to manage or enhance labor in specific situations. Evidence-based guidelines support its use in the following circumstances:
1. To Speed Up Labor
If labor is progressing slowly, AROM can intensify contractions by releasing amniotic fluid, which stimulates the production of prostaglandins. Research published in Cochrane Reviews (2013) found that AROM, when combined with other interventions, can slightly shorten the duration of labor.
2. To Induce Labor
As part of an induction process, AROM may be combined with medications like Pitocin to establish a regular contraction pattern. Studies in Obstetrics and Gynecology (2007) show that AROM can be effective in initiating labor in women whose cervixes are partially dilated.
3. To Monitor the Baby More Closely
If there are concerns about the baby’s well-being, AROM allows for the use of internal monitoring devices, such as fetal scalp electrodes, which provide more accurate heart rate readings than external monitors.
4. To Identify Meconium-Stained Fluid
Breaking the sac can reveal whether the amniotic fluid contains meconium (the baby’s first bowel movement). According to American Family Physician (2015), meconium-stained fluid occurs in about 12% of deliveries and can signal fetal stress.
5. To Encourage Baby’s Descent
Releasing the fluid can help the baby move lower into the pelvis, especially if their head is well-positioned. This can make contractions more effective and reduce labor time.
When Is AROM Typically Recommended?
AROM is generally recommended when:
- Labor is progressing slowly or has stalled.
- Induction is underway, and breaking the water may help establish a labor pattern.
- Closer fetal monitoring is needed due to signs of distress.
- The baby’s position or descent could benefit from the release of amniotic fluid.
It’s important to note that AROM is only performed when the cervix is partially dilated (usually at least 3–4 cm) and effaced. If the cervix is closed, AROM is ineffective and not indicated.
Benefits of AROM
AROM can offer several potential benefits, supported by research and clinical guidelines:
1. Shortening Labor Duration
By intensifying contractions, AROM may help labor progress more quickly. A study in The Journal of Maternal-Fetal & Neonatal Medicine (2011) found that AROM can reduce labor time, particularly in the active phase of labor.
2. Reducing the Need for Pitocin
In some cases, AROM may eliminate the need for higher doses of Pitocin, as the natural release of prostaglandins can stimulate effective contractions.
3. Enhanced Monitoring
If there are concerns about the baby’s heart rate or well-being, AROM allows for internal monitoring, which is more accurate than external devices.
4. Improving Baby’s Position
Releasing the amniotic fluid can help the baby’s head engage with the cervix more effectively, reducing the likelihood of needing assisted delivery tools like forceps or vacuum extraction.
Risks of AROM
While AROM is generally safe, it does carry some risks, which should be considered carefully:
1. Increased Risk of Infection
Once the amniotic sac is broken, the protective barrier around the baby is gone, increasing the risk of infection for both mother and baby. According to The Lancet (2015), the risk of infection rises significantly if labor extends beyond 24 hours after AROM.
2. Cord Prolapse
If the baby’s head is not well-engaged in the pelvis, breaking the water can sometimes cause the umbilical cord to slip into the birth canal ahead of the baby, a rare but serious emergency. Studies show that cord prolapse occurs in 0.14–0.62% of births following AROM (Obstetrics & Gynecology, 2014).
3. Intensified Contractions
The release of prostaglandins often leads to stronger and more frequent contractions, which can increase discomfort and the likelihood of requiring pain relief interventions like an epidural.
4. No Guarantee of Progression
While AROM can stimulate labor, it’s not always effective. If labor stalls after AROM, additional interventions, including a cesarean delivery, may be needed.
Should You Agree to AROM?
Deciding whether to agree to AROM is a personal choice that depends on your individual circumstances and labor progression.
Questions to Ask Your Provider:
- Why is AROM being recommended in my situation?
- Are there alternatives to AROM that could achieve the same goal?
- What are the risks and benefits specific to my labor?
Final Thoughts
Artificial rupture of membranes is a common intervention that can help manage labor, but it’s not always necessary. Understanding the evidence-based benefits and risks, asking questions, and advocating for your preferences can help you make informed decisions about whether AROM is right for you.
Having a supportive care team and a knowledgeable doula by your side can make all the difference in navigating these decisions and ensuring a positive birth experience.
