Being common does not equate to being normal. Vaginal examinations to 'check the cervix' are frequently conducted during the antenatal period, however, they are not without risks, and concerns about informed consent and the autonomy of pregnant women are increasingly being raised.
' Lets' just check the cervix, shall we?', is a common question that is asked in the later stages of pregnancy when attending for an antenatal appointment.
The purpose of a vaginal examination, aka 'checking the cervix', is to assess the cervix’s readiness for labour by checking dilation, effacement, and the baby’s position. Cervical sweeps involve a more invasive procedure where a healthcare provider inserts a finger into the cervix and performs a sweeping motion to separate the membranes, which may release prostaglandins and encourage labour.
The effectiveness of sweeps varies, with some research suggesting that they may not significantly alter labour outcomes or timing, particularly if the body is not ready for labour.
"There is no evidence to support routine vaginal examinations during late pregnancy. They can introduce infection, cause discomfort, and do not predict when labor will begin or how it will progress. Vaginal exams are often used as a way to 'check progress,' but in reality, they tell us very little and can unnecessarily lead to interventions that disrupt the natural process." -Dr. Rachel Reed in Why Induction Matters
Dr. Reed emphasizes that vaginal exams often provide little useful information and can potentially cause harm when performed routinely without medical necessity.
Risks Associated with Cervical Checks and Sweeps
Despite their common use, vaginal examinations and sweeps at the end of pregnancy carry several risks:
Accidental Breaking of the Waters (Membranes):
One of the primary risks of both cervical checks and sweeps is the accidental rupture of membranes. This can lead to premature labour, which might not be desirable if the baby is not yet fully developed. A study published in Obstetrics & Gynecology highlighted that while rare, inadvertent membrane rupture is a recognized complication of cervical sweeps .
Maternal Discomfort and Pain:
Many women report significant discomfort or pain during cervical checks and sweeps. The invasive nature of these procedures can cause physical and emotional distress, particularly if the woman feels unprepared or unsupported. Research published in the British Journal of Obstetrics and Gynaecology notes that some women experience severe pain during these procedures, which can lead to a negative birth experience .
Increased Risk of Infection:
Inserting fingers into the cervix can introduce bacteria, potentially leading to infection. While this risk is low, it is a concern, especially if the woman is known to be GBS positive, the procedure is repeated frequently or if proper hygiene is not maintained.
Lack of Informed Consent
A significant concern surrounding vaginal examinations and sweeps is the lack of informed consent. Many women report feeling pressured into having these procedures without being fully informed of the risks or being offered alternatives. A study in Midwifery found that women often undergo cervical sweeps without adequate discussion about the potential risks and benefits, leading to feelings of disempowerment and loss of control .
This lack of informed consent is problematic as it undermines the woman’s autonomy and her right to make decisions about her own body. Informed consent is not just about signing a form; it involves a clear, open conversation where the woman is informed of the purpose of the procedure, the associated risks, and her right to decline. It’s essential that healthcare providers respect a woman’s decision, even if she chooses to decline the procedure.
"Many women undergo vaginal examinations without true informed consent. They are often not informed about the lack of evidence for the procedure or its potential risks, and in some cases, they are not even aware they have the right to decline. This contributes to a culture where routine practices are normalized, even when they are unnecessary or unwanted." -Dr. Rachel Reed in The Hidden Impact of Vaginal Examinations.
Women’s Experiences of Cervical Sweeps
Women’s experiences of cervical sweeps vary widely. Some report positive experiences, especially if the procedure successfully stimulates labour and avoids formal induction. However, many women describe the procedure as uncomfortable or painful, and some feel that it was done without their full understanding or consent.
A qualitative study published in the Journal of Reproductive and Infant Psychology highlighted that some women felt their discomfort and preferences were not adequately acknowledged during cervical sweeps. These negative experiences can impact a woman’s overall perception of her birth experience and may lead to feelings of disempowerment.
The Importance of Informed Consent and Autonomy
Informed consent is a cornerstone of ethical medical practice, particularly in pregnancy and childbirth, where interventions can have significant emotional and physical impacts. It’s crucial that healthcare providers engage in meaningful discussions with pregnant women about the benefits, risks, and alternatives to cervical checks and sweeps.
Women should be empowered to make informed decisions and should be made aware that they have the right to decline any procedure that makes them uncomfortable. By fostering a culture of respect and open communication, healthcare providers can ensure that women feel supported and respected in their birth choices, leading to a more positive birth experience overall.
In conclusion
While cervical checks and sweeps are common practices intended to assess and stimulate labour, they carry risks that should be clearly communicated to pregnant women. Informed consent is essential in ensuring that women can make empowered decisions about their care, and their right to decline these procedures must be respected to support a positive and respectful birth experience.
