Chapter 19 Promoting physiological birth
Learning outcomes for this chapter are:
1. To explore the practicalities, sensitivities and systems that promote physiological birth
2. To highlight the factors and organisational culture that can inhibit this approach in midwifery practice
3. To explore the evidence concerning continuity of midwifery care
4. To provide information about midwifery practices that enhance physiological birth.
The imaginary story of the birth of Jack Taylor, presented in this chapter as a scenario, can be used for discussion and analysis in small groups. As a similar group exercise, practitioners and students can present ‘real-life’ stories from practice in order to analyse the factors that can promote or inhibit physiological birth in any given situation. Such an exercise can be incorporated in continuing professional development exercises such as peer review, interdisciplinary learning, case review and workshops.
INTRODUCTION
In this chapter, the phrase ‘promoting physiological birth’1 is used deliberately as an alternative to the commonly heard phrase ‘the midwifery art of keeping birth normal’. As Holly Kennedy (2004) has suggested, the notion of ‘normal’ is hardly in keeping with the midwifery philosophy of embracing the concept of each woman’s birth being viewed by her as essentially ‘special’. However, women and most maternity care providers are unlikely to use the term ‘physiological’, and the word ‘normal’ is embedded in the documentation and discourses that shape and reflect contemporary maternity service provision. Importantly, the term ‘normal’ is used to identify the primary domain of the midwife, a sphere of practice that is clearly defined as separate from the technological or medical interventions associated with complications, identified here by the World Health Organization (WHO):
The midwife appears to be the most appropriate and cost effective type of care provider to be assigned to the care of normal pregnancy and birth, including risk assessment and the recognition of complications. (WHO 1996, p 6)
Fulfilling this role is not as straightforward as it might seem. Midwives in Western countries often work in hospitals where computerised summaries identifying ‘normal birth’ do not necessarily reflect physiological processes or the efforts of practitioners to promote physiological birth. This was identified in an important epidemiological study of 1464 births in five consultant maternity units in the United Kingdom (Downe et al 2001). Once women who had artificial rupture of membranes, induction and acceleration of labour, epidural anaesthesia or episiotomy were removed from the equation, only 16.9% of women having their first baby and 30.1% of women having a second or subsequent baby could be classified as having a ‘normal’ birth. This study shrinks the domain of midwives as ‘guardians of the normal’ and raises questions as to whether we are ‘failing’ in this role (Beech 1997). Furthermore, there are mounting concerns about the limited learning opportunities for practitioners where the promotion of physiological birth is limited by ‘technocratic’ approaches in institutions (Davis-Floyd 2001; Kitzinger 2000; Leap 2002).
THE MIDWIFE AS ‘GUARDIAN OF THE NORMAL’
A long history of interprofessional rivalry lies behind the 1996 WHO statement quoted above and the contemporary rhetorical notion of the midwife as ‘guardian of the normal’. Before men entered the birthing arena, most women in European countries were attended at home by women they knew, one of whom might well be referred to as ‘the midwife’ due to her acknowledged role and expertise (Wilson 1995). If problems occurred, it was not unusual for a more experienced midwife to be called to help out. As described in the diaries of Catherine Schrader, a 17th century midwife who was called to complicated births in Holland, this often involved internal podalic version and bringing the baby out by its feet (Marland 1987).
A core professionalising strategy used by midwives in Western countries in the 18th and 19th centuries was the relinquishing of complicated (and lucrative) birth practice to the medical profession in return for the domain of ‘normal childbirth’ (Donnison 1977; Leap & Hunter 1993). This strategy responded to, and set up, a dynamic that has had far-reaching consequences in terms of gender and class inequalities and the collective psychological effects of subordination (Witz 1992). Pathology was the pivotal factor for role division, and doctors were presented as the superior professionals, educated at a higher level than midwives in order to carry out rescuing manoeuvres associated with the complications of childbirth. In comparison, the midwife’s role was shrunk to that of ‘caring’ for women who did not need interventions, and to recognising problems and calling for a doctor to ‘correct’ the situation and intervene in a timely fashion.
The fraught negotiations that led to the role delineation between midwives and doctors have given way to a situation with its own set of interprofessional tensions. While fulfilling the imperative to adopt good collaborative relationships with obstetricians in the interests of women and safe practice, the midwife often defines the boundaries of ‘normal’ in situations that are intricate and unclear. She2 engages with women and makes decisions in a culture dominated by the ideologies of authoritative medical science and its quest for certainty. Evidence-based protocols and policies often do not ‘fit’ with the complexity of individual women’s psychological and social situations and the impact of the environment. This has led to a childbirth culture in which it is increasingly difficult to find consensus on what constitutes ‘normal birth’ other than an absence of technical intervention (Downe & McCourt 2008).
THE RATIONALE FOR PROMOTING PHYSIOLOGICAL BIRTH
The boundaries of what is considered ‘normal’ are at the heart of the passionate discussions that happen whenever midwives get together. In recent years, midwives have been addressing these issues by identifying the complexity of their role in being ‘with woman’ and promoting physiological birth. This is often explained in terms of the potentially self-transformative nature of birth and the profound long-term consequences of empowerment for women, their families and society (Leap 2004; Leap & Anderson 2008). The promotion of physiology begins in early pregnancy and is about far more than aiming for an uncomplicated birth. It is concerned with a journey to motherhood that will have profound consequences
SCENARIO
The birth of Jack Taylor at St Average Hospital
Daniel didn’t faint. He is in awe of Michelle and thanks God for the ‘life-saving wonders of modern medicine’. Michelle and Daniel are very grateful to the staff of St Average and give them a huge box of chocolates when they go home with Jack four days after his birth.
Thus begins the new life of Michelle and Daniel as proud parents of little Jack Taylor …
for each individual woman in terms of how she feels about herself, her body and her capabilities (Thompson 2004). Whether or not she eventually gives birth without intervention, a woman who feels powerful is in a good situation to take on becoming a new mother.
Birth is not only about making babies. Birth is also about making mothers—strong, competent, capable mothers who trust themselves and know their inner strength. (Katz Rothman 1996, pp 253–254)
Sadly, the opposite is also true—women can end up feeling disempowered and emotionally fragile as a result of an experience of childbirth that rendered them passive in the face of intervention (Kitzinger 2000). This chapter explores some of these issues, relating them to the practicalities of midwifery practice and initiatives that optimise women’s potential to feel good about their experiences of pregnancy, giving birth and nurturing a new baby. Some strategies are suggested that might help to promote physiology, even in situations where midwives are ‘swimming against the tide’ of interventionist thinking. The word ‘interventionist’ rather than ‘medicalised’ is used in an attempt to acknowledge that it is not only doctors who can hinder physiological birth.
PROMOTING PHYSIOLOGICAL BIRTH
Access to midwifery care
From the scenario, some might question the usefulness of midwife-led care, given that Michelle and Daniel appear grateful and happy about the birth of their son, Jack. Although the members of staff at St Average were all strangers to Michelle and Daniel, they were friendly, kind and competent, which is what women say is important to them (Green et al 1998; Lee 1997).
Such challenges raise complex questions about how to evaluate women’s experiences of birth in terms of their ‘satisfaction’ and how midwifery and the promotion of physiological birth might be implicated. It can be argued that women have a vested interest in evaluating their experience positively in the postnatal period and that, in many situations, it is impossible for women to know how their experience might have been otherwise. For example, research in South Australia has shown that women like Sophie choose private obstetric care because they have no knowledge of midwifery. However, once such women are exposed to midwife-led care, they identify that they would choose it in subsequent pregnancies (Zadoroznyj 2000).
This is an important consideration because midwives can play a crucial role in promoting psychosocial wellbeing. This was identified by Anne Oakley and colleagues (Oakley et al 1990, 1996) in a randomised controlled trial, which showed that the effect of midwives making themselves available, in a ‘listening ear’ capacity throughout pregnancy, had profound long-term consequences for the relationships and social lives of women, their children and their families.
Midwifery continuity of care
The anxiety of pregnant women who do not know which midwife will be there in labour for them, and whether this makes a difference to outcomes, has not been well captured by researchers on the whole. Confusion about the term ‘midwifery continuity of care’ and what it actually means in practice has added to the difficulty of making comparisons in research studies, particularly in exploring how women feel about their care (Sandall et al 2008). Furthermore, the notion of randomising women in studies does not lend itself to enquiry into choices, processes and relationships. A Cochrane Review, however, has identified that midwifery-led care has the potential to make a significant difference to the promotion of physiological birth when comparisons are made with standard care from physicians and midwives, as identified in Box 19.1 (Hatem et al 2008).
Box 19.1 Midwifery-led vs other models of care for childbearing women
Cochrane Review
Women who had midwife-led care were:
• less likely to be admitted to hospital antenatally
• less likely to use regional analgesia
• less likely to have babies needing resuscitation
• less likely to have an episiotomy
• less likely to have an instrumental birth
• less likely to experience the loss of their baby before 24 weeks gestation
Women who had midwife-led care were:
• more likely to experience no intrapartum analgesia/anaesthesia
• more likely to have a spontaneous vaginal birth
• more likely to feel in control during labour and birth
• more likely to be attended by a known midwife
• more likely to initiate breastfeeding
• more likely to be pleased with their antenatal, intrapartum and postnatal care
• more likely to experience their babies having a shorter length of hospital stay.

Midwifery caseload practice
An increasing body of literature identifies the need for studies to look specifically at the midwifery continuity of care provided in a caseload practice model. Non-randomised studies of this form of care suggest that there are improved outcomes for women where they are able to establish relationships with midwives during pregnancy (Benjamin et al 2001; Cornwell et al 2008; Fereday et al 2009; McCourt & Stevens 2005; Page et al 2001; Sandall et al 2001; Turnbull et al 2009).
The Albany Midwifery Group Practice in the United Kingdom is held up as an example of a community-based midwifery group practice that operates a caseload practice model and makes a difference to outcomes in a disadvantaged community (Huber & Sandall 2006, 2008; Reed 2002a, 2002b). An evaluation of this group practice identified the fact that the midwives were very successful at facilitating normality in pregnancy and birth (Sandall et al 2001). Significant differences in outcomes were reported in terms of: increased satisfaction and rates of normal vaginal birth, home birth and breastfeeding; and reduced rates of induction, caesarean section, use of pharmacological pain relief, and perineal trauma (Sandall et al 2001).
Preliminary evaluations of the Northern Women’s Community Midwifery Project (NWCMP) in the northern suburbs of Adelaide suggest that similar positive outcomes for women can be achieved through replicating the model in other contexts (Nixon et al 2003). The NWCMP has similar features to the Albany Midwifery Group Practice, in that the midwives:
