PV Exam During Pregnancy

Are you pregnant and wondering about the purpose of a PV examination? A PV examination, or per vaginal examination, is a common procedure during pregnancy, especially as you approach your due date. It involves a healthcare provider inserting gloved fingers into the vagina to assess the cervix and the baby's position. This blog post, written by Dr. Rukkayal Fathima, a fertility specialist in Chennai, aims to provide a comprehensive understanding of PV examinations during pregnancy, addressing their benefits, procedure, risks, and necessity.

What Is a PV Examination and Why Is It Done?

A PV examination, also known as a pelvic exam, is a manual assessment performed by a healthcare provider to evaluate the condition of the cervix, vagina, and surrounding pelvic organs. During pregnancy, its primary purpose shifts to monitoring the progress of labour, assessing cervical dilation (opening) and effacement (thinning), and determining the baby's position in the birth canal. This information helps healthcare providers make informed decisions about the management of labour and delivery.

In my clinical experience across multiple locations in Chennai, I've found that many expectant mothers are anxious about PV examinations. They often ask me about the necessity and frequency of these exams. It's crucial to understand that while PV examinations provide valuable information, they are not always mandatory. The decision to perform a PV examination should be made collaboratively between the patient and her healthcare provider, considering the individual circumstances and preferences. NICE (National Institute for Health and Care Excellence) guidelines recommend offering a 4-hourly vaginal examination during labour or if there is concern about progress.

Beyond labour monitoring, PV examinations can sometimes help identify potential issues such as vaginal infections or unusual bleeding. According to ICMR (Indian Council of Medical Research) guidelines, P/A (per abdomen) & P/S (per speculum) examination are recommended to confirm the amount of bleeding & rule out local causes if a woman presents with bleeding per vaginum. However, these are not the primary reasons for performing a PV examination during labour. Modern obstetrics also employs other methods for assessing fetal well-being and labour progress, such as ultrasound and external monitoring, but these do not provide the same direct assessment of cervical status.

PV Examination Step-by-Step Process

Understanding the PV examination procedure can help alleviate anxiety and empower you to communicate effectively with your healthcare provider. Here’s a breakdown of what to expect:

1. Preparation: You will be asked to lie on your back on an examination table with your knees bent and feet supported (often in stirrups). It's important to relax your muscles as much as possible to minimize discomfort.
2. Hygiene: The healthcare provider will wash their hands thoroughly and wear sterile gloves.
3. Lubrication: A sterile, water-based lubricant is applied to the gloved fingers to ease insertion.
4. Insertion: The healthcare provider gently inserts one or two fingers into the vagina.
5. Assessment:
   • Cervical Dilation: The opening of the cervix is measured in centimetres (cm), from 0 cm (closed) to 10 cm (fully dilated).
   • Cervical Effacement: The thinning of the cervix is described as a percentage, from 0% (thick) to 100% (fully thinned).
   • Fetal Position: The healthcare provider assesses the baby's presenting part (usually the head) and its position in relation to the pelvis.
   • Station: This refers to how far down the baby's head has descended into the pelvis, measured in relation to the ischial spines (bony landmarks in the pelvis).
   • Membranes: The healthcare provider will check whether the amniotic sac (membranes) is intact or has ruptured.
6. Communication: Throughout the examination, the healthcare provider should communicate what they are doing and explain their findings. Don't hesitate to ask questions or express any concerns you have.

The entire PV examination typically takes only a few minutes. While it may cause some discomfort or pressure, it should not be painful. If you experience significant pain, inform your healthcare provider immediately. In my experience, patients who understand the procedure and communicate openly with their healthcare provider tend to have a more positive experience. Remember, you are in control, and you can ask to stop the examination at any time.

Benefits of PV Examinations During Pregnancy

PV examinations offer several benefits during pregnancy, especially in the context of labour and delivery:

• Monitoring Labour Progress: This is the most crucial benefit. PV examinations provide real-time information about cervical dilation and effacement, helping to track the progress of labour and identify potential delays.
• Guiding Management Decisions: The findings from PV examinations can guide decisions about interventions such as augmentation of labour (using medication to strengthen contractions) or the need for a Cesarean section. According to a Cochrane review, routine four‐hourly vaginal examinations may result in more women having their labor augmented.
• Assessing Fetal Position and Presentation: Knowing the baby's position and how it is presenting (e.g., head first, breech) is essential for planning a safe delivery.
• Detecting Abnormalities: In some cases, PV examinations can help detect abnormalities such as a prolapsed umbilical cord (where the umbilical cord descends into the vagina ahead of the baby), which requires immediate intervention.
• Providing Reassurance: For many women, knowing that labour is progressing normally can be reassuring and help them feel more confident.

It's important to weigh these benefits against the potential risks and discomfort associated with PV examinations. Open communication with your healthcare provider is key to making informed decisions that align with your individual needs and preferences. While ultrasound and external monitoring can provide some information about fetal well-being, they cannot replace the detailed assessment of cervical status and fetal position that a PV examination provides.

PV Examination Risks During Pregnancy

While generally safe, PV examinations do carry some potential risks:

• Discomfort or Pain: This is the most common concern. While the examination should not be intensely painful, it can cause discomfort or pressure, especially if the muscles are tense.
• Infection: There is a small risk of introducing bacteria into the vagina, potentially leading to an infection. Strict adherence to sterile technique minimizes this risk.
• Premature Rupture of Membranes (PROM): Rarely, a PV examination can cause the amniotic sac to rupture prematurely, especially if the membranes are already weakened.
• Bleeding: Light spotting or bleeding can occur after a PV examination, particularly if the cervix is highly sensitive. This is usually not a cause for concern.
• Anxiety and Stress: For some women, the procedure itself can be a source of anxiety and stress, especially if they have a history of trauma or discomfort with pelvic examinations.

It's important to note that the risks associated with PV examinations are generally low, especially when performed by experienced healthcare providers using proper technique. Discuss any concerns you have with your doctor or midwife, and don't hesitate to ask questions about the procedure and how they minimize the risks.

Is PV Examination Necessary in Pregnancy?

The necessity of PV examinations during pregnancy is a topic of ongoing discussion. While they offer valuable information about labour progress, they are not always mandatory, and alternative methods of assessment are available.

The decision to undergo a PV examination should be made collaboratively between the patient and her healthcare provider, considering the individual circumstances, preferences, and risk factors. Factors that may influence this decision include:

• Labour Progress: If labour is progressing normally and the woman is comfortable, frequent PV examinations may not be necessary.
• Medical History: Women with a history of preterm labour, PROM, or other complications may benefit from more frequent monitoring.
• Patient Preference: Some women prefer to have frequent PV examinations to stay informed about their progress, while others prefer to avoid them unless absolutely necessary.
• Availability of Alternative Methods: Ultrasound and external monitoring can provide some information about fetal well-being and contractions, but they cannot replace the detailed assessment of cervical status provided by a PV examination.
• Clinical Trial Data: A clinical trial (NCT01570413) is studying whether pelvic examination is necessary in patients with first trimester vaginal bleeding/lower abdominal pain when an intra-uterine pregnancy is seen on ultrasound.

Here's a comparison of PV examinations with other methods:

Ultimately, the decision about whether or not to have a PV examination is a personal one. Discuss the benefits and risks with your healthcare provider and make an informed choice that feels right for you.
