In this guest blog for midwives, midwifery lecturer Mercedes Perez Botella considers the latest Cochrane evidenceCochrane Reviews are systematic reviews. In systematic reviews we search for and summarize studies that answer a specific research question (e.g. is paracetamol effective and safe for treating back pain?). The studies are identified, assessed, and summarized by using a systematic and predefined approach. They inform recommendations for healthcare and research. on how to push in the second stage of labour. She also reflects on aspects of this part of the birth experience that aren’t captured in these trialsClinical trials are research studies involving people who use healthcare services. They often compare a new or different treatment with the best treatment currently available. This is to test whether the new or different treatment is safe, effective and any better than what is currently used. No matter how promising a new treatment may appear during tests in a laboratory, it must go through clinical trials before its benefits and risks can really be known. – a good reminder that best practice will bring together evidence, clinical judgement and the preferences of the women in your care.

Some clinicians (including me) have long believed that directed pushing does not reduce the duration of the second stage of labour, that the impact on perineal damage is unchanged and that neonatal status as measured by the Apgar at 5 minutes and admission to the neonatal care unit are not improved by this type of pushing technique. A Cochrane Review ‘Pushing/bearing down methods for the second stage of labour’ (updated March 2017) has found “no conclusive evidence to support or refute any specific style or recommendation as part of routine clinical practice” and that “patient preference and clinical situations should guide decisions.”
Spontaneous or directed pushing?
Active, or directed, pushing consists of encouraging the woman to push for as long as she can during a contraction. It tends to involve some form of cheerleading (see these two examples: https://www.youtube.com/watch?v=q9EiV2JXwWE https://www.youtube.com/watch?v=9gkFttT8T8M).
On the other hand, spontaneous pushing is more concerned with supporting the woman to follow her own instincts to bear down at the rateThe speed or frequency of occurrence of an event, usually expressed with respect to time. For instance, a mortality rate might be the number of deaths per year, per 100,000 people. and with the strength that her body prompts her to do.
Do either directed or spontaneous pushing facilitate woman centred care? Do either of them improve the birth experience for all involved?
Looking beyond trials
The evidence used in this review arises from studies of mixed quality, which the authors rightly acknowledge, so well designed randomizedRandomization is the process of randomly dividing into groups the people taking part in a trial. One group (the intervention group) will be given the intervention being tested (for example a drug, surgery, or exercise) and compared with a group which does not receive the intervention (the control group). controlled trialsA trial in which a group (the ‘intervention group’) is given a intervention being tested (for example a drug, surgery, or exercise) is compared with a group which does not receive the intervention (the ‘control group’). (RCTs) might show us in the future more than we now know. However, beyond this review, and leaving aside for one minute RCTs – we do know they are considered the best type of evidence… or are they always? (Greenhalgh and Buckingham, 2010) – we should now be asking what added benefits, not measured by the review, can spontaneous or directed pushing bring about?
Empowering women
Let’s think for a minute about those women who will feel empowered by the fact that they were able to birth without anyone shouting in their ears, “Keep it going!”, “Once more!”, “Don’t waste the contraction!” and the like. These are portrayed constantly by the media and convince women that, actually, being told how and when to push is a normal part of the process and you must wait for those instructions and follow them rigidly. However, feeling disempowered, not listened to and being told what to do are well known triggers of postnatal depression and problems with bonding (Leahy-Warren, McCarthy and Corcoran, 2011).
Spontaneous pushing: a kinder method
If one measures the birth experience by the rate of neonatal admission to SCBU at birth or perineal damage (both primary outcomesOutcomes are measures of health (for example quality of life, pain, blood sugar levels) that can be used to assess the effectiveness and safety of a treatment or other intervention (for example a drug, surgery, or exercise). In research, the outcomes considered most important are ‘primary outcomes’ and those considered less important are ‘secondary outcomes’. in this review) then we have no reliable evidence that one type of pushing facilitates a better birth experience. However, spontaneous pushing is a kinder method, more aligned with following birth physiology and with the philosophy that encompasses woman-centred care and the belief in women’s bodies and their ability to birth.
Women know what to do
I have always held the strong belief that women (especially those with no epidural analgesia) know where and how to push, especially if they are encouraged to adopt an optimal position (i.e. anything but on the bed!). The feeling tends to be so overwhelming that it is hard to be confused as to where one needs to push.
Must we “do something”?
This belief that women know how to push is not held by all birth attendants, who feel they must guide women to push in the right place, with their mouths closed etc. They feel compelled to “do something” to help the situation, many times with the good intention of ridding the woman of this somewhat challenging (one could say?) event.
In other instances, pressure from the system to empty beds quicker tends to be used as an argument for employing directed pushing. Bed pressure is a phenomenally common and stressful situation in many labour wards, but not the right argument to employ directed pushing, especially now given the lack of evidence for the benefit of one type over another in this respect.
“The less we do, the more we give”
With regards to some birth attendants feeling they “have to do something”, this leads us to reconsider the arguments of Nicky Leap when she analysed how we sometimes feel compelled to do something while we look after women in labour. “The less we do; the more we give” (Leap, 2010) becomes so powerfully true when we give women control over their expulsive efforts.
Put women at the centre
This review has shown that we don’t yet have the evidence that there is anything to be gained by directing women to push and the authors conclude that “women should be encouraged to bear down based on their preferences and comfort”. If nothing positive can be gained by interfering with the natural process of labour, then let it be. Ensure your role is to provide authentic support, embedded in a philosophy of care that puts the woman truly at the centre of it and which nurtures the process to develop as nature intended.
‘Remember you are facilitating another person’s process. It is not your process. Do not intrude. Do not control. Do not force your own needs and insights into the foreground. If you do not trust a person’s process, that person will not trust you’ (Heider, 1985).
