Vaginal Examinations: What You Need To Consider

During your pregnancy it’s a fair bet to say that a stranger will, at some point, request to examine your vagina. What fun! A vaginal examination is a relatively quick procedure where your midwife or other caregiver will insert their fingers into your vagina to feel your cervix. As with all things birth, whether you have them or not is entirely your choice. And as with most things there’s some real pros and cons either way.

Let’s have a look at the facts.

Number one on the con list is that someone is having a thorough rummage in your vagina. It’s a physically invasive procedure, sometimes painful, often disruptive to the flow of labour and can put you into a vulnerable state. Now, hopefully you’ll have some rapport built up with your caregiver by this point in the proceedings, but they’ll still be a relative stranger in the scheme of things and what’s more likely to send your adrenaline rising and oxytocin plummeting than being put in that situation? And as we know, you need a good supply of oxytocin – the love hormone – in labour to keep your uterus contracting nice and efficiently; when something happens that makes us uncomfortable, stressed or fearful, the amygdala part of your brain triggers your fight or flight response which releases a burst of adrenalin, inhibiting both oxytocin and the endorphins which are acting as your body’s natural painkillers.

Vaginal examinations are physical, and so present an infection risk. Perhaps not a huge risk in the western world where caregivers have access to plenty of soap, water and gloves, but a risk all the same. Bacteria can be pushed up the vagina, pass through the cervix and enter the uterus. The risk increases if the amniotic sack has displaced already, and some infections can be quite serious for babies in utero. Shockingly, in one study it was found that women who have had a vaginal examination in labour have 80% greater number of different bacteria in the cervix than those who hadn’t.

When a vaginal examination is carried out they can be useful storytellers to your caregiver, telling them important information, more on that below. However, they can also give you and your caregiver misleading tales. There are few rules in labour, no definitive timings, no guarantees that they will progress in exactly the way you have planned. So what happens if you’ve been in latent labour for hours and hours and get told you’re ‘only’ at 3 centimetres dilated? What if you’ve been in active labour for half an hour and you’re told you’re at 8 centimetres dilated? Do either of these things mean that your baby will be here at a specified time? Nope…in both situations baby could still be hours away from making their arrival, or they could be here within the hour. And yet your care pathway may very well be altered to fit the story that your caregiver believes your cervix is telling them. Not only that, but your own expectations can become hinged on the number you’re told and if the story doesn’t go the way you’re expecting then your flow of labour can be interrupted and throw you off kilter. If things happen more quickly or more slowly than you anticipated you could experience panic and fear, and fear leads to pain. And don’t forget distance measuring with only fingers for guides is subjective – if more than one person carries out the examination you could be in the position where measurements are miscalculated!

So what, then, are the pros from having a vaginal examination? Well they can give your caregiver information that they can use to build a picture of what’s happening in your labour. How far dilated you are alongside other factors can give an indication (but not a guarantee!) of how close to baby’s arrival you are.

Vaginal examinations can also tell your caregiver what position your cervix is in. As the cervix dilates it moves from a backwards facing position which protects baby, to a forward-facing position allowing an easy descent down the birth canal for baby.

The examination will also assist in ensuring you know your baby’s position. Again, this isn’t unique to vaginal examinations but in certain conditions such as malpresentation it’s important to have a clear picture of the situation so appropriate care can be given.

Vaginal examinations can be really useful if things aren’t progressing quite how you’d be expecting them to be. If they seem to be taking a wee while longer than expected to make their arrival an internal examination by a midwife can check their descent and position. This will tell them if baby’s position means they might need help to come along (such as asynclitic, breech or occiput posterior). It can also tell them if an intervention such as rupturing of the membranes would be appropriate to carry out. So where does this leave you and your choices? Vaginal examinations can be an important part of your care but should be used alongside other practices from your caregiver as a diagnostic tool. How judiciously they’re used is entirely up to you and your comfort level with them.

Birth Positions Which Can Help You Give Birth More Easily

Many women enter pregnancy having only seen labour occur on television, where women are laid on a bed, knees up, chin to chest, ‘purple pushing’ interspersed with screaming. Understandably, this can lead to some nervousness on the pregnant woman’s part!

The weight of research[1] shows that upright labouring positions can provide advantages to a birthing mother. In an upright position, gravity can assist the baby within the uterus by bringing it down and out, as well as helping keep it in the optimal foetal position when coupled with leaning forward. Being upright can also reduce the risk of aorto-caval compression which could result in a reduced blood supply to the baby. Upright positioning uses gravity to bring a stronger connection between the baby’s head and the cervix, releasing oxytocin and giving more efficient uterine contractions. In traditional squat and kneeling positions the pelvic dimensions become wider, allowing the baby to pass through with more ease. As well as increasing the comfort of the mother and improving the overall birth experience, the positive impact of these positions on the pace and efficiency of labour tend to make interventions less necessary and therefore less common.

The benefits of upright positioning don’t stop there either. Studies have shown that an upright position during the first stage can both reduce pain in the labouring woman[2] and shorten that stage, reducing the need for pain relief and preventing exhaustion in the woman. Interestingly the physical position a woman is in to give birth can also have a psychological impact: being able to find a comfortable position and knowing that the woman’s own movements are helping the baby be born more easily can give feelings of control and stem any fear and anxiety arising from the situation. By reducing stress and discomfort, these psychological responses to a good birthing position can make the whole experience more positive.

Despite the considerable evidence for the benefits of upright birthing positions, the actual positions that women give birth in do not reflect the evidence or national evidence based practice guidelines and nearly half of deliveries are made in a semi-recumbent position[3]. In developed countries where pregnancy and labour has become medicalized, interventions such as foetal monitoring and different types of analgesia can limit the options for position of a birthing woman[4]. A Cochrane review theorises that women are encouraged to push in supine or semi-recumbent positions simply because it is more convenient for the healthcare professional to gain access to the woman rather than being beneficial to the woman. Women ‘choose’ these positions on the basis that they think it is expected of them when presented with a bed in a hospital setting, coupled with the cultural expectation ingrained in them as seen previously, through the medium of television[5]. It is important that the woman knows what positions will help her and to have the confidence to try these positions without being led by the healthcare practitioner in attendance.

A Cochrane review[6] compared the risk of interventions and birth outcomes for upright birthing positions in comparison to non-upright birthing positions and concluded that upright positions can be associated with a shorter length of first stage of labour; a reduction in the use of epidural analgesia; almost a quarter less likely to have an assisted delivery; 20% less likely to have an episiotomy but 35% more likely to have a second-degree tear; 50% of births are less likely to have an abnormal foetal heartrate and 65% are more likely to have a blood loss of more than 500mL. The review found that there was no difference in birthing positions on the length of the second stage of labour; emergency caesarean rates; third or fourth-degree tears; blood transfusion rates; neonatal admissions or perinatal deaths. As there is only a negative impact on second-degree tear rates and blood loss by being in an upright birthing position, it seems clear that upright birthing positions really are the most beneficial, especially as tears can heal more quickly and neatly than episiotomies and there is no knock-on effect on blood transfusions needed.

The birth position chosen by the labouring woman may have a specific purpose. Different positions can bring relief to different complications. For example, if shoulder dystocia presents then the Gaskin Manoeuvre[7] of turning onto all fours and being on hands and knees will cause changes to the pelvic shape which will allow the shoulder to release and the baby to be born.  All fours positioning will be useful for women whose baby is or has turned occiput posterior in labour. Gravity and rotations can help the baby rotate to anterior position[8] although Balaskas points out that when the baby begins to crown each woman should become as vertical as possible to help it out. The use of these positions and a mother’s existing familiarity with them will help to reduce the need for interventions.

There is not just a physiological impact from birth positions on a woman, but psychological too, and these can prefigure the birth itself. Knowing that she can speed up her labour or slow it down if she feels overwhelmed puts her in a position of power. A woman who feels like she is in control of her birth, who feels as though she has a variety of tools at her fingertips to assist a range of experiences she may encounter, will be more empowered to deal with how her labour goes. In contrast, being in a supine position promotes a vulnerability in a healthcare setting that the woman must shed in order to birth most effectively; being upright will automatically help with that.

Ultimately a woman must birth in the position in which she is most comfortable, and the care providers around her must work with her to help her accomplish that goal.
