Can I have a natural placental birth after induction?

5581007563_260038813a“Is it possible to have a natural placental birth after induction?”

That’s a question I get asked a lot.

My first reply to this question usually begins with me saying that I am not sure that any part of a labour that follows medical induction could accurately be described as ‘natural’. Especially when the induction involves synthetic oxytocin. But the really key point here is that, while I’m a strong advocate for women’s autonomous decision making, there is a really good reason not to suddenly remove synthetic oxytocin once it has been started.

Neither do I think that physiological placental birth is as risky as some would have you believe. In fact, I co-wrote the book in which we went through the evidence and explained this. And I have attended hundreds of women who have birthed their placentas naturally. So I would consider my own comfort zone to be really quite wide in this area. But induction of labour interferes with normal physiology. And hormones. So it is inadvisable to suddenly stop a synthetic oxytocin drip after a woman had been receiving this for several hours. Particularly if she had not yet birthed her placenta.

The reason for this is simple: oxytocin is needed to birth the placenta and to keep the uterus in good shape once it has done so, but synthetic oxytocin (as found in the drip used to induce or accelerate labour) inhibits the woman’s ability to produce her own natural oxytocin.


Symphonies and mountain climbing

I have a lot of faith in a woman’s ability to release appropriate amounts of her own oxytocin if she is in natural labour. (If you are not already aware that oxytocin flows better if women are disturbed as little as possible, I would invite you to read up on this too. It’s not as easy to create an oxytocin-friendly environment in a hospital as it is at home, but it’s not impossible either). Women’s bodies are rather amazing and they do complex and powerful things to grow, birth and feed a baby.

Some people compare the hormones that are involved in labour to a musical symphony. They work together and in harmony, like a good orchestra. Over the course of the journey, a rhythm develops and builds to a crescendo. During the last bars of the ‘labour’ movement of this symphony, pulses of oxytocin help the placenta to separate and birth. Then, the now empty uterus can begin to return to its non-pregnant size. That reduction in size helps reduce bleeding from the placental site.

Yet this only happens if labour begins and progresses physiologically (naturally).

When labour is induced, synthetic oxytocin is often given. And the presence of synthetic oxytocin inhibits the woman’s ability to produce her own oxytocin. Under these conditions, we can’t expect a woman to suddenly be able to produce enough natural oxytocin to facilitate the birth of the placenta AND the vital postnatal clamping down of her uterus from a standstill. That would be like parachuting someone out of a helicopter to a point halfway up Mount Everest and then expecting them to be able to sprint straight to the top. No chance to warm up or get used to the freezing cold, oxygen-depleted air.

Worse still, what if our imaginary mountain runner had been given unlimited oxygen and a nice big chunk of dark chocolate every ten minutes from when they woke up that morning until they piled out of the helicopter? Then, the supply of both is suddenly taken away just as they start to run. What odds would you give them on reaching the top now?


The problem with synthetic oxytocin

I know. It’s not a perfect analogy, but it is important to recognize that induction of labour entails a serious amount of intervention. And that the consequences of synthetic oxytocin are significant. Synthetic oxytocin may be comprised of the same molecule that we produce in our bodies, but there is a crucial difference. When we produce oxytocin in our own bodies, “it is released into the brain, as well as into the circulation. Oxytocin released into the brain induces beneficial adaptive effects during birth and postpartum” (Uvnäs-Moberg et al 2019). The oxytocin that we make in our own bodies is hugely beneficial. It reduces stress and anxiety and gives us a sense of wellbeing. Pain is lowered, mother-baby interaction increases and the stage is perfectly set for breastfeeding. Natural oxytocin confers many other benefits too. One of the greatest risks of synthetic oxytocin – and thus of induction of labour – is that it takes all of those benefits away.


Induction as a package deal

So synthetic oxytocin interferes with the physiology and symphony of labour, and it has other potential side effects, such as causing the uterus to contract too much. This can cause a lot of pain for the woman. It can also have detrimental effects on the baby and, in some cases, these can be serious. It is for this reason that induction of labour might be best thought of as a ‘package deal’. Yes, there are some choices which can be made along the way. But some of the core elements of induction (including repeated vaginal examinations, ongoing fetal monitoring and medical management of elements of labour, such as the birth of the placenta) are an intrinsic and, sorry, fairly necessary part of that package.  Even to those of us who spend our lives stretching the fabric and journeying the boundaries. It is not that we’ve stopped trusting women’s bodies. We absolutely trust the physiology of minimally-disturbed labour. But the drugs used to induce labour are potent substances which interfere with the ability of women’s bodies to ‘do their thing’ and which have side effects. Therefore, where labour is artificially induced, the effects of these drugs need to be monitored and sometimes compensated for.

I really empathise with those women who feel they have no choice about having an induction but wish they did. I have lots of resources on my website that I hope will help you get full information before making your decision. It’s important that anyone offered induction of labour understands the rationale behind the package nature of the deal. This is not always explained well.

Perhaps my experience isn’t the norm, but I am asked this question so often that I am concerned that the differences between spontaneous and induced labour are not well enough understood. With one in three women in the UK (and even more in some areas of the UK and elsewhere) having their labours induced, I would say this needs to be rectified. If women don’t understand the differences well enough, then how on earth can their choices be informed ones?

    Thanks Sara I enjoyed reading this post (and I liked the mountaineer analogy!). In my experience so many women are not given nearly enough information regarding what ‘being induced’ actually means, and what impact this will have on her birth experience.

      Me too! Glad you enjoyed the post!

    Excellent article! May I add that it’s not just that many women aren’t being given full information regarding medical induction, many don’t research on their own and just expect for their medical caregivers to just spontaneously spout everything, too. Women need to do their research about giving birth, not accepting injections for their baby like vitamin K and the Hepatitis B vaccination, delayed cord clamping and why it’s imperative to not clamp or cut the cord until after it’s done pulsating, and even on why not to circumcise their sons. Women need to be proactive in their own care and the care of their baby, and only if they search out their own answers will they really know what to expect and how to protect their little one. This article is a good start!

    This makes total sense to me. Induction is a package, just as having an epidural is. Individual women may decide to take on that whole package, feeling in their heart and head that it it worth it in their unique circumstances. Knowing what the whole package involves is key to making that truly informed decision before the process is set in motion.

      Thanks, Dot. It’s always good to know one isn’t alone in having such thoughts! 🙂

    Couldn’t agree more – well said, I too am a fan of physiological placental birth and have a lot of experience with it, and am totally concerned about the amount of inductions being done andd the paucity of information given to women.

      Thanks, Jane; we really do need to get more information out there! 🙂

    Another fabulous insight into why we need to be educating women about all aspects of childbirth. I’m currently writing an essay about how to improve women’s knowledge and understanding of IOL before they arrive at the hospital expecting a dream birth and a beautiful baby in their arms in next few hours. I despair when they arrive and announce how they are looking forward to this being their baby’s birthday. Most of them still have no idea how long it could take and even what they can expect from the process. My suggestion is a DVD that they can be given either at 38 week appointment or when IOL is discussed due to factors which may result in iol. This means that the community midwife does not need to rush through it in already tight appointment times but that the woman can take it home watch it as many times as she needs can share with family and havd time to question midwives about anything she is not sure about. Informed choice is vital and the DVD should ensure pros and cons of both iol and expectant management are covered. Hopefully when she returns for her next appointment or when she arrives at hospital she is more aware of what to expect. And who knows some of them may decide to wait and see and decline iol?!

      Thank you, Lesley 🙂 I think lots of different kinds of media with information would be great!
