Effects of Multi-Mechanism Complementary Therapy on Pain and Anxiety During Labor Latency in Primiparous Women

Objective: Evaluate the efficacy of single and mixed complementary therapies, with different analgesic mechanisms, in relieving pain and anxiety during the late labor period. Design and method: In this study, 145 primiparous women with 2-3 cm dilation of the cervix were randomly assigned to one of five groups: control group (psychological comfort), comprehensive group, aroma group, auricular acupuncture group, and music group. The groups were distributed equally (1:1:1:1 ratio), and pain and anxiety scores were assessed at 30, 60, and 120 minutes post-intervention in each group. Outcomes and measures: Compared to the control group, all intervention groups showed lower pain scores. The comprehensive group had the largest reduction in pain scores at 30, 60, and 120 minutes post-intervention. The auricular point, aroma, and music groups also demonstrated significant reductions in pain scores at different time points. Only the comprehensive group had a statistically significant reduction in anxiety at 30 minutes post-intervention compared to the control group. However, at 60 and 120 minutes post-intervention, all intervention groups showed lower anxiety scores compared to the control group. Conclusion: The optimal effects of each therapy varied in terms of timing and duration. Combination therapy showed a greater effect size than single complementary therapy.

Navigating intensive altered states of consciousness: How can the set and setting key parameters promote the science of human birth?

The subjective childbirth experience is crucial from a public health standpoint. There is a correlation between a negative childbirth experience and a poor mental state after birth, with effects that go far beyond the postpartum (PP) period. This paper offers a new approach as to how birthing experiences, and birth in general, can be navigated. The theory of set and setting proves that psychedelic experiences are shaped, first and foremost, by the mindset of an individual entering a psychedelic experience (set) and by the surroundings in which the experience happens (setting). In research on altered states of consciousness during psychedelic experiences, this theory explains how the same substance can lead to a positive and life-changing experience or to a traumatic and frightening experience. Because recent studies suggest that birthing women enter an altered state of consciousness during physiological birth ("birthing consciousness"), I suggest analyzing the typical modern birthing experience in terms of set and setting theory. I argue that the set and setting key parameters can help design, navigate, and explain many psychological and physiological elements of the human birth process. Thus, an operative conclusion that emerges from the theoretical analysis presented in this paper is that framing and characterizing the birth environment and birth preparations in terms of set and setting is a central tool that could be used to promote physiological births as well as subjective positive birthing experiences, which is currently a primary, yet unreached goal, in modern obstetrics and public health.

Routine vaginal examinations compared to other methods for assessing progress of labour to improve outcomes for women and babies at term

BACKGROUND

Routine vaginal examinations are undertaken at regular time intervals during labour to assess whether labour is progressing as expected. Unusually slow progress can be due to underlying problems, described as labour dystocia, or can be a normal variation of progress. Evidence suggests that if mother and baby are well, length of labour alone should not be used to decide whether labour is progressing normally. Other methods to assess labour progress include intrapartum ultrasound and monitoring external physical and behavioural cues. Vaginal examinations can be distressing for women, and overdiagnosis of dystocia can result in iatrogenic morbidity due to unnecessary intervention. It is important to establish whether routine vaginal examinations are effective, both as an accurate measure of physiological labour progress and to distinguish true labour dystocia, or whether other methods for assessing labour progress are more effective. This Cochrane Review is an update of a review first published in 2013.

OBJECTIVES

To compare the effectiveness, acceptability, and consequences of routine vaginal examinations compared with other methods, or different timings, to assess labour progress at term.

SEARCH METHODS

For this update, we searched Cochrane Pregnancy and Childbirth Trials Register (which includes trials from CENTRAL, MEDLINE, Embase, CINAHL, and conference proceedings) and ClinicalTrials.gov (28 February 2021). We also searched the reference lists of retrieved studies.

SELECTION CRITERIA

We included randomised controlled trials (RCTs) of vaginal examinations compared with other methods of assessing labour progress and studies assessing different timings of vaginal examinations. Quasi-RCTs and cluster-RCTs were eligible for inclusion. We excluded cross-over trials and conference abstracts.

DATA COLLECTION AND ANALYSIS

Two review authors independently assessed all studies identified by the search for inclusion in the review. Four review authors independently extracted data. Two review authors assessed risk of bias and certainty of the evidence using GRADE.

MAIN RESULTS

We included four studies that randomised a total of 755 women, with data analysed for 744 women and their babies. Interventions used to assess labour progress were routine vaginal examinations, routine ultrasound assessments, routine rectal examinations, routine vaginal examinations at different frequencies, and vaginal examinations as indicated. We were unable to conduct meta-analysis as there was only one study for each comparison.  All studies were at high risk of performance bias due to difficulties with blinding. We assessed two studies as high risk of bias and two as low or unclear risk of bias for other domains. The overall certainty of the evidence assessed using GRADE was low or very low.  Routine vaginal examinations versus routine ultrasound to assess labour progress (one study, 83 women and babies) Study in Turkey involving multiparous women with spontaneous onset of labour. Routine vaginal examinations may result in a slight increase in pain compared to routine ultrasound (mean difference -1.29, 95% confidence interval (CI) -2.10 to -0.48; one study, 83 women, low certainty evidence) (pain measured using a visual analogue scale (VAS) in reverse: zero indicating 'worst pain', 10 indicating no pain). The study did not assess our other primary outcomes: positive birth experience; augmentation of labour; spontaneous vaginal birth; chorioamnionitis; neonatal infection; admission to neonatal intensive care unit (NICU). Routine vaginal examinations versus routine rectal examinations to assess labour progress (one study, 307 women and babies) Study in Ireland involving women in labour at term. We assessed the certainty of the evidence as very low. Compared with routine rectal examinations, routine vaginal examinations may have little or no effect on: augmentation of labour (risk ratio (RR) 1.03, 95% CI 0.63 to 1.68; one study, 307 women); and spontaneous vaginal birth (RR 0.98, 95% CI 0.90 to 1.06; one study, 307 women). We found insufficient data to fully assess: neonatal infections (RR 0.33, 95% CI 0.01 to 8.07; one study, 307 babies); and admission to NICU (RR 1.32, 95% CI 0.47 to 3.73; one study, 307 babies). The study did not assess our other primary outcomes: positive birth experience; chorioamnionitis; maternal pain. Routine four-hourly vaginal examinations versus routine two-hourly examinations (one study, 150 women and babies) UK study involving primiparous women in labour at term. We assessed the certainty of the evidence as very low. Compared with routine two-hourly vaginal examinations, routine four-hourly vaginal examinations may have little or no effect, with data compatible with both benefit and harm, on: augmentation of labour (RR 0.97, 95% CI 0.60 to 1.57; one study, 109 women); and spontaneous vaginal birth (RR 1.02, 95% CI 0.83 to 1.26; one study, 150 women). The study did not assess our other primary outcomes: positive birth experience; chorioamnionitis; neonatal infection; admission to NICU; maternal pain. Routine vaginal examinations versus vaginal examinations as indicated (one study, 204 women and babies)  Study in Malaysia involving primiparous women being induced at term. We assessed the certainty of the evidence as low. Compared with vaginal examinations as indicated, routine four-hourly vaginal examinations may result in more women having their labour augmented (RR 2.55, 95% CI 1.03 to 6.31; one study, 204 women). There may be little or no effect on: • spontaneous vaginal birth (RR 1.08, 95% CI 0.73 to 1.59; one study, 204 women); • chorioamnionitis (RR 3.06, 95% CI 0.13 to 74.21; one study, 204 women); • neonatal infection (RR 4.08, 95% CI 0.46 to 35.87; one study, 204 babies); • admission to NICU (RR 2.04, 95% CI 0.63 to 6.56; one study, 204 babies). The study did not assess our other primary outcomes of positive birth experience or maternal pain.

AUTHORS' CONCLUSIONS

Based on these findings, we cannot be certain which method is most effective or acceptable for assessing labour progress. Further large-scale RCT trials are required. These should include essential clinical and experiential outcomes. This may be facilitated through the development of a tool to measure positive birth experiences. Data from qualitative studies are also needed to fully assess whether methods to evaluate labour progress meet women's needs for a safe and positive labour and birth, and if not, to develop an approach that does.

Challenges in using Mental Contrasting with Implementation Intentions (MCII) for preparation for natural birth: A feasibility study

OBJECTIVE

Women who plan a natural birth can benefit from strategies and/or resources that help them prepare for and cope with labour pain. This study aims to identify the feasibility of using Mental Contrasting with Implementation Intentions (MCII) for preparation of primiparous women for natural childbirth. Secondary aims are to test the acceptability of a health-focused information leaflet, and to describe how participants with high natural birth intentions cognitively prepare for birth.

METHODS

In third trimester, ten primiparous women participated in this interventional study with follow-up. A health-focused information leaflet on physiological childbirth, MCII, a mental strategy that helps people achieve a desired goal by envisioning obstacles and how to overcome them, and a researcher-developed questionnaire which contained the CBSEI-C32, was used. Survey data were analysed using a combination of descriptive statistics and deductive theoretical thematic analysis.

RESULTS

The health-focused leaflet was exclusively judged positively. Nine women did not use MCII as instructed, they did not find it helpful for childbirth preparation and wished to have a more positive, health-focused approach towards childbirth. Two themes emerged from the participants' responses: 'the ability to give birth' which was supported through childbirth preparedness, coping strategies, confidence and external supports and 'the uncertainty of giving birth' which included fears and worries about possible adverse events and the baby's health.

CONCLUSION

MCII was not a promising tool for natural childbirth preparation among primiparous women in Germany. Our findings show that women prefer a positive, health-focused approach, rather than thinking about overcoming obstacles, when they prepare for childbirth.

The birthing brain: A lacuna in neuroscience

During pregnancy, maternal brain neuroplasticity indicates vast neurofunctional and neuroanatomical changes. Recent findings documented a similarly massive readjustment after pregnancy. Currently, these brain changes are interpreted as preparation for and adjustment of the maternal brain to motherhood. Yet, this perspective leaves many questions unsolved. Neuroscientific studies have not yet been conducted to determine the brain areas that function during natural childbirth even though physiological birth is the natural process of women who have reproduced successfully throughout two million years of evolution of the genus Homo. It is rational to believe that the female brain is an active and crucial actor during birth and that birth, itself, is a process that requires brain neuroplasticity. Lack of studies of the birthing brain and brain preparation for birth is a significant lacuna in neuroscience research. I demonstrate theoretically that a new hypothesis for complementary interpretation of maternal brain neuroplasticity is reasonable: Certain maternal brain changes during pregnancy can be interpreted asbrain preparation for birth and certain maternal brain changes after birth can be interpreted asbrain recovery after the tremendous event of birth. This essay can be a starting point for new directions in neuroscience studies.

The AEDUCATE Collaboration. Comprehensive antenatal education birth preparation programmes to reduce the rates of caesarean section in nulliparous women. Protocol for an individual participant data prospective meta-analysis

INTRODUCTION

Rates of medical interventions in normal labour and birth are increasing. This prospective meta-analysis (PMA) proposes to assess whether the addition of a comprehensive multicomponent birth preparation programme reduces caesarean section (CS) in nulliparous women compared with standard hospital care. Additionally, do participant characteristics, intervention components or hospital characteristics modify the effectiveness of the programme? METHODS AND ANALYSIS: Population: women with singleton vertex pregnancies, no planned caesarean section (CS) or epidural.Intervention: in addition to hospital-based standard care, a comprehensive antenatal education programme that includes multiple components for birth preparation, addressing the three objectives: preparing women and their birth partner/support person for childbirth through education on physiological/hormonal birth (knowledge and understanding); building women's confidence through psychological preparation (positive mindset) and support their ability to birth without pain relief using evidence-based tools (tools and techniques). The intervention could occur in a hospital-based or community setting.Comparator: standard care alone in hospital-based maternity units.

OUTCOMES

Primary: CS.Secondary: epidural analgesia, mode of birth, perineal trauma, postpartum haemorrhage, newborn resuscitation, psychosocial well-being.Subgroup analysis: parity, model of care, maternal risk status, maternal education, maternal socio-economic status, intervention components.

STUDY DESIGN

An individual participant data (IPD) prospective meta-analysis (PMA) of randomised controlled trials, including cluster design. Each trial is conducted independently but share core protocol elements to contribute data to the PMA. Participating trials are deemed eligible for the PMA if their results are not yet known outside their Data Monitoring Committees.

ETHICS AND DISSEMINATION

Participants in the individual trials will consent to participation, with respective trials receiving ethical approval by their local Human Research Ethics Committees. Individual datasets remain the property of trialists, and can be published prior to the publication of final PMA results. The overall data for meta-analysis will be held, analysed and published by the collaborative group, led by the Cochrane PMA group.

Birth as a neuro-psycho-social event: An integrative model of maternal experiences and their relation to neurohormonal events during childbirth

BACKGROUND

Psychological aspects of labor and birth have received little attention within maternity care service planning or clinical practice. The aim of this paper is to propose a model demonstrating how neurohormonal processes, in particular oxytocinergic mechanisms, not only control the physiological aspects of labor and birth, but also contribute to the subjective psychological experiences of birth. In addition, sensory information from the uterus as well as the external environment might influence these neurohormonal processes thereby influencing the progress of labor and the experience of birth.

METHODOLOGY

In this new model of childbirth, we integrated the findings from two previous systematic reviews, one on maternal plasma levels of oxytocin during physiological childbirth and one meta-synthesis of women´s subjective experiences of physiological childbirth.

FINDINGS

The neurobiological processes induced by the release of endogenous oxytocin during birth influence maternal behaviour and feelings in connection with birth in order to facilitate birth. The psychological experiences during birth may promote an optimal transition to motherhood. The spontaneous altered state of consciousness, that some women experience, may well be a hallmark of physiological childbirth in humans. The data also highlights the crucial role of one-to-one support during labor and birth. The physiological importance of social support to reduce labor stress and pain necessitates a reconsideration of many aspects of modern maternity care.

CONCLUSION

By listening to women's experiences and by observing women during childbirth, factors that contribute to an optimized process of labor, such as the mothers' wellbeing and feelings of safety, may be identified. These observations support the integrative role of endogenous oxytocin in coordinating the neuroendocrine, psychological and physiological aspects of labor and birth, including oxytocin mediated. decrease of pain, fear and stress, support the need for midwifery one-to-one support in labour as well as the need for maternity care that optimizes the function of these neuroendocrine processes even when birth interventions are used. Women and their partners would benefit from understanding the crucial role that endogenous oxytocin plays in the psychological and neuroendocrinological process of labor.

Using Acupuncture in Labor Pain and Childbirth-Related Issues: A Narrative Review

BACKGROUND

Latent threats, such as prolonged labor duration and postpartum hemorrhage, endanger women and newborns during and post childbirth, which produce burdens on natal care and public health expenditures. Acupuncture, a traditional Chinese medical practice, has increasingly been used for labor delivery in various countries to cope with these problems.

METHOD

This narrative review searched 29 English and Chinese electronic databases. Thirty-one empirical studies, carried out in Asia, America, Africa, the Middle East, Europe, and Australia were reviewed according to inclusion and exclusion criteria.

RESULTS

Acupuncture is adopted with positive signs toward labor pain relief, delivery mode, labor duration, postpartum hemorrhage, APGAR score (an evaluation for a neonatal evaluation), and birth weight.

DISCUSSION

With support of earlier studies, the satisfactory effects of acupuncture on labor delivery reviewed in this research have been noted by obstetric researchers and scholars, physicians, nurses, and midwives.

CONCLUSION

This review recommends the use of acupuncture in obstetric profession with respect to maternal-related healthcare.

Nursing Support During Latent Phase Labor: A Scoping Review

PURPOSE

The purpose of this scoping review was to synthesize the literature on nursing support during the latent phase of the first stage of labor. In 2014, the definition of the beginning of active labor changed from 4 centimeters (cm) to 6 cm cervical dilation. More women may have an induction of labor based on results of recent research showing no causal increase in risk of cesarean birth with elective induction of labor for low-risk nulliparous women. Therefore, in-hospital latent phase labor may be longer, increasing the need for nursing support.

DESIGN

Scoping review of the literature from 2009 to present.

METHODS

We conducted the review using key words in PubMed, CINAHL, and Scopus. Search terms included different combinations of "latent or early labor," "birth," "support," "nursing support," "obstetrics," and "onset of labor." Peer-reviewed research and quality improvement articles from 2009 to present were included if they had specific implications for nursing care during the latent phase of labor. Articles were excluded if they were not specific to nursing, focused exclusively on tool development, or were from the perspective of pregnant women or providers only.

RESULTS

Ten articles were included. Results were synthesized into six categories; support of physiologic labor and birth, the nurse's own personal view of labor, birth environment, techniques and tools, decision-making, and importance of latent labor discussion during the prenatal period.

CLINICAL IMPLICATIONS

Support for physiologic labor and birth is an important consideration for use of nonpharmacological methods during latent labor. The nurse's own personal view on labor support can influence the support that laboring women receive. Nurses may need additional education on labor support methods.

Rationalism and the disembodiment of modern childbirth: the case for an ecology of childbirth

The paper proposes a genealogy of the biomedical paradigm surrounding childbirth, with the aim of deconstructing the principles of rationalism that led to the objectification of the body and to the consequent commodification of birth. We intend to demonstrate how such a conception of the body and of sensibility determines the birth process, which leads us to consider it an event that is relational in nature. Methodologically, this deconstruction is carried out through a critical-descriptive genealogy of the theoretical assumptions of the rationalist conception of the body. By developing the concept of ecology of childbirth, we intend to call into question this relational nature of the body and to recover the value of corporeality and embodiment as a language of proximity, within a theoretical framework of the ethics of difference. This vindication of the ecological-relational nature of sensibility has the potential to establish a dynamic of responsibility and cooperation capable of subverting the rationalist logic of control and the dominion of the current biomedical paradigm.

Investigation of the impact of birth by cesarean section on fetal and maternal metabolism

PURPOSE

Elective cesarean section (CS) was related to long-term adverse health effects in the offspring, but little is known about underlying mechanisms. Our study investigates the metabolic changes in both maternal and cord blood associated with CS in comparison to vaginal delivery (VD) to explore potential causal pathways.

METHODS

Samples obtained from PREOBE study participants were subjected to LC-MS/MS-targeted metabolomics comprising > 200 metabolites.

RESULTS

Elective CS showed an impact on both maternal and cord blood metabolomes. In maternal blood, the CS group showed lower levels of phospholipids (PL), principally ether-linked phosphatidylcholines (aaPC), pyruvic acid, branched chain keto-acids (BCKA), and other gluconeogenic substrates, but since the CS group showed different HDL levels in comparison to the VD group, we could not exclude contribution of the latter in the findings. In cord blood, the most remarkable finding in the CS group was the high levels of Cys; conversely, the lower levels of non-esterified fatty acids (NEFA), some tricarboxylic acid (TCA) cycle metabolites, gluconeogenic substrates, markers of β-oxidation, and the sum of hexoses were lower in CS-born babies in addition to tendentially lower levels of PL.

CONCLUSIONS

We speculate that lower levels of maternal and fetal corticosteroids in CS, due to less stressful condition, cause metabolic perturbations at birth initiating future negative health outcomes. This further supports the early programming hypothesis.

The Effect of Massage Therapy Using Frangipani Aromatherapy Oil to Reduce the Childbirth Pain Intensity

BACKGROUND

Pain during labor is one of the worst pains experienced by women. If the woman cannot adapt to it, it may lead to uncoordinated uterine contractions causing a long-complicated labor with the possibility of death of the mother and baby.

PURPOSE

The aim of the study is to observe the effect of massage treatment using frangipani aromatherapy oil to reduce the childbirth pain intensity.

SETTING

Pembantu Dauh Puri Health Center Denpasar, Bali, Indonesia.

PARTICIPANTS

Pregnant women in labor.

RESEARCH DESIGN

A quasi-experimental research design was used with pretreatment and posttreatment groups and a control. The respondents were 70 pregnant women in labor in Pembantu Dauh Puri Health Center Denpasar, Bali, Indonesia. Data were collected during scheduled observation and were analyzed using the Mann-Whitney statistical test.

INTERVENTION

The participants in the treatment group were massaged with frangipani aromatherapy oil by rubbing and pressing the hand palms to the back region at thoracic vertebrae 10, 11, 12 and lumbar 1 levels. The women in the control group were massaged with virgin coconut oil in the same manner as that done to the treatment group.

MAIN OUTCOME MEASURE

This study aimed to investigate the potential of frangipani aromatherapy oil to be used as maternity care in helping pregnant women become more comfortable in the process of normal birthing, based on modified midwife examination form, which contain Numeric Rating Score (NRS), and interviews with the participants to measure the pain intensity.

RESULT

Before the massage treatment, most of the respondents experienced severe pain. While receiving massage without aromatherapy, respondents mostly still experienced severe pain. However, after a massage treatment using frangipani oil aromatherapy, most respondents experienced reduced pain. There was a statistically significant effect of massage treatment using frangipani aromatherapy oil on the childbirth pain intensity (p < .001).

CONCLUSION

In this study, massage treatment using frangipani oil aromatherapy decreased the childbirth pain intensity.

Women's psychological experiences of physiological childbirth: a meta-synthesis

OBJECTIVE

To synthesise qualitative studies on women's psychological experiences of physiological childbirth.

DESIGN

Meta-synthesis.

METHODS

Studies exploring women's psychological experiences of physiological birth using qualitative methods were eligible. The research group searched the following databases: MEDLINE, CINAHL, PsycINFO, PsycARTICLES, SocINDEX and Psychology and Behavioural Sciences Collection. We contacted the key authors searched reference lists of the collected articles. Quality assessment was done independently using the Critical Appraisal Skills Programme (CASP) checklist. Studies were synthesised using techniques of meta-ethnography.

RESULTS

Eight studies involving 94 women were included. Three third order interpretations were identified: 'maintaining self-confidence in early labour', 'withdrawing within as labour intensifies' and 'the uniqueness of the birth experience'. Using the first, second and third order interpretations, a line of argument developed that demonstrated 'the empowering journey of giving birth' encompassing the various emotions, thoughts and behaviours that women experience during birth.

CONCLUSION

Giving birth physiologically is an intense and transformative psychological experience that generates a sense of empowerment. The benefits of this process can be maximised through physical, emotional and social support for women, enhancing their belief in their ability to birth and not disturbing physiology unless it is necessary. Healthcare professionals need to take cognisance of the empowering effects of the psychological experience of physiological childbirth. Further research to validate the results from this study is necessary.

'I thought they were going to handle me like a queen but they didn't': A qualitative study exploring the quality of care provided to women at the time of birth

OBJECTIVE

To explore experiences of care during labour and birth from the perspectives of both the healthcare provider and women receiving care, to inform recommendations for how the quality of care can be improved and monitored, and, to identify the main aspects of care that are important to women.

DESIGN

A descriptive phenomenological approach. 53 interviews and 10KII as per table 1 took place including in-depth interviews (IDI), focus group discussions (FGD) and key informant interviews (KII) conducted with women, healthcare providers, managers and policy makers. Following verbatim transcription thematic framework analysis was used to describe the lived experience of those interviewed.

SETTING

11 public healthcare facilities providing maternity care in urban Tshwane District, Gauteng Province (n = 4) and rural Waterberg District, Limpopo Province (n = 7), South Africa.

PARTICIPANTS

Women who had given birth in the preceding 12 weeks (49 women, 7 FGD and 23 IDI); healthcare providers working in the labour wards (33 healthcare providers; nurses, midwives, medical staff, 5 FGD, 18 IDI; managers and policy makers (10 KII).

FINDINGS

Both women and healthcare providers largely feel alone and unsupported. There is mutual distrust between women and healthcare providers exacerbated by word of mouth and the media. A lack of belief in women's ability to make appropriate choices negates principles of choice and consent. Procedure- rather than patient-centred care is prioritised by healthcare providers. Although healthcare providers know the principles of good quality care, this was not reflected in the care women described as having received. Beliefs and attitudes as well as structural and organisational problems make it difficult to provide good quality care. Caring behaviour and environment as well as companionship are the most important needs highlighted by women. Professional hierarchy is rarely seen as supportive by healthcare providers but when present, good leadership changes the culture and experience of women and care providers. The use of mobile phones to provide feedback regarding care was positively viewed by women.

CONCLUSION

Clarity regarding what a healthcare facility can (or cannot provide) is important in order to separate practice issues from structural and organisational constraints. Improvements in quality that focus on caring as well as competence should be prioritised. Increased dialogue between healthcare providers and users should be encouraged and prioritised.

IMPLICATIONS FOR PRACTICE

A renewed focus is needed to ensure companionship during labour and birth is facilitated. Training in respectful maternity care needs to prioritise caring behaviour and supportive leadership.

A Nurse's Guide to Supporting Physiologic Birth

Physiologic birth promotes the practice of normal labor and birth, in which a woman's innate power is supported and unnecessary interventions are avoided. Nurses are in a unique position to support physiologic birth because they attend almost all births. Several resources are available to assist nurses in promoting physiologic birth, including BirthTOOLS.org, a new online resource developed by the American College of Nurse-Midwives in collaboration with other organizations. By using resources such as BirthTOOLS.org and others, nurses can become familiar with the evidence surrounding physiologic birth and can contribute to improved patient safety and quality of care by supporting physiologic birth. http://dx.doi.org/10.1016/j.nwh.2015.12.009.

Pronurturance Plus at birth: A risk reduction strategy for preventing postpartum haemorrhage

BACKGROUND

Postpartum haemorrhage (PPH) rates continue to rise in the developed world. A recent study found that any skin-to-skin contact and breastfeeding within 30min of birth was associated with an almost 50% reduction in PPH rates. Improved oxytocin release is the biological reason proposed to explain this. The combination of skin-to-skin contact and breastfeeding within 30min of birth is termed 'Pronurturance'. Midwifery theory and research claims that optimal third stage care is more holistic than simple Pronurturnace which suggests that further reductions in PPH rates may be possible.

QUESTION

What can midwives and women do to minimise blood loss in the third and fourth stages of labour?

METHOD

We present a new theory that describes and explains how to optimise the woman's reproductive psychophysiology in the third and fourth stages of labour to ensure a well contracted uterus which inhibits excessive bleeding regardless of risk status or whether active management was used. In developing the Pronurturance Plus theory we expand upon what is already known about oxytocin in relation to simple pronurturance to integrate concepts from birth territory theory, cognitive neuroscience, mindfulness psychology and the autonomic nervous system to develop an holistic understanding of how to optimise care and minimise PPH.

CONCLUSION

Pronurturance Plus is a psycho-biologically grounded theory which is consistent with existing evidence. It is free, natural and socially desirable.

Effects of skin-to-skin contact and breastfeeding at birth on the incidence of PPH: A physiologically based theory

BACKGROUND

The importance of optimising maternal/baby psychophysiology has been integrated into contemporary midwifery theories but not in the detail required to really understand the underpinning biological basis.

METHOD

The functioning of the autonomic nervous system, as it relates to the uterus is reviewed. The physiology of myometrial cell contraction and relaxation is outlined. The main focus is on the factors that affect the availability and uptake of oxytocin and adrenaline/noradrenaline in the myometrial cells. These are the two key neuro-hormones, active in the 3rd and 4th stages of labour, that affect uterine contraction and retraction and therefore determine whether the woman will have an atonic PPH or not.

DISCUSSION

The discussion explains and predicts the physiological functioning of the uterus during the 3rd and 4th stages of labour when skin-to-skin contact and breastfeeding occurs and when it does not.

CONCLUSION

This biologically based theory hypothesises that to achieve and maintain eutony and eulochia, midwives and birthing women should ensure early, prolonged and undisturbed skin-to-skin contact for mother and baby at birth including easy access for spontaneous breastfeeding.
