RESUMEN

BACKGROUND: Women use a range of non-pharmacological pain relief methods to reduce labour pain intensity and to help manage labour pain. AIMS: The purpose of this intervention study was to determine whether virtual reality would have an effect on labour pain intensity. Virtual reality has been shown to be effective in reducing pain in other acute pain settings. MATERIALS AND METHODS: This study was an intervention study in labour in a cross-over within-subjects design (Clinical Trials Registry Number: ACTRN12618001776291P). Fourteen participants reported their pain and had their heart rate and blood pressure measured during active labour while using and not using virtual reality. RESULTS: There were significantly lower reported pain scores (6.14 compared to 7.61, P < 0.001) and maternal heart rate (79.86 beats per minute compared to 85.57, P = 0.033) and mean arterial pressure (88.78 mmHg compared to 92.61 mmHg, P = 0.022) were lower when using virtual reality compared to when not using virtual reality during active labour. CONCLUSION: This study makes an important contribution to the field of virtual reality in labour and birth. It is consistent with other recent findings of reduced pain in labour and links decreased pain scales to heart rate and blood pressure, the physiological markers of pain.

RESUMEN

BACKGROUND: In a randomized placebo-controlled trial, we previously found that the probiotic Lactobacillus rhamnosus HN001 (HN001) taken by mothers from 35 weeks of gestation until 6 months post-partum if breastfeeding and their child from birth to age 2 years halved the risk of eczema during the first 2 years of life. We aimed to test whether maternal supplementation alone is sufficient to reduce eczema and compare this to our previous study when both the mother and their child were supplemented. METHODS: In this 2-centre, parallel double-blind, randomized placebo-controlled trial, the same probiotic as in our previous study (HN001, 6 × 109 colony-forming units) was taken daily by mothers from 14-16 weeks of gestation till 6 months post-partum if breastfeeding, but was not given directly to the child. Women were recruited from the same study population as the first study, where they or their partner had a history of treated asthma, eczema or hay fever. RESULTS: Women were randomized to HN001 (N = 212) or placebo (N = 211). Maternal-only HN001 supplementation did not significantly reduce the prevalence of eczema, SCORAD ≥ 10, wheeze or atopic sensitization in the infant by 12 months. This contrasts with the mother and child intervention study, where HN001 was associated with reductions in eczema (hazard ratio (HR): 0.39, 95% CI 0.19-0.79, P = .009) and SCORAD (HR = 0.61, 95% 0.37-1.02). However, differences in the HN001 effect between studies were not significant. HN001 could not be detected in breastmilk from supplemented mothers, and breastmilk TGF-ß/IgA profiles were unchanged. CONCLUSION: Maternal probiotic supplementation without infant supplementation may not be effective for preventing infant eczema.

RESUMEN

The study aims to assess whether supplementation with the probiotic Lactobacillus rhamnosus HN001 (HN001) can reduce the prevalence of gestational diabetes mellitus (GDM). A double-blind, randomised, placebo-controlled parallel trial was conducted in New Zealand (NZ) (Wellington and Auckland). Pregnant women with a personal or partner history of atopic disease were randomised at 14-16 weeks' gestation to receive HN001 (6×109 colony-forming units) (n 212) or placebo (n 211) daily. GDM at 24-30 weeks was assessed using the definition of the International Association of Diabetes and Pregnancy Study Groups (IADPSG) (fasting plasma glucose ≥5·1 mmol/l, or 1 h post 75 g glucose level at ≥10 mmol/l or at 2 h ≥8·5 mmol/l) and NZ definition (fasting plasma glucose ≥5·5 mmol/l or 2 h post 75 g glucose at ≥9 mmol/l). All analyses were intention-to-treat. A total of 184 (87 %) women took HN001 and 189 (90 %) women took placebo. There was a trend towards lower relative rates (RR) of GDM (IADPSG definition) in the HN001 group, 0·59 (95 % CI 0·32, 1·08) (P=0·08). HN001 was associated with lower rates of GDM in women aged ≥35 years (RR 0·31; 95 % CI 0·12, 0·81, P=0·009) and women with a history of GDM (RR 0·00; 95 % CI 0·00, 0·66, P=0·004). These rates did not differ significantly from those of women without these characteristics. Using the NZ definition, GDM prevalence was significantly lower in the HN001 group, 2·1 % (95 % CI 0·6, 5·2), v. 6·5 % (95 % CI 3·5, 10·9) in the placebo group (P=0·03). HN001 supplementation from 14 to 16 weeks' gestation may reduce GDM prevalence, particularly among older women and those with previous GDM.

RESUMEN

BACKGROUND: Worldwide there is increasing interest in the manipulation of human gut microbiota by the use of probiotic supplements to modify or prevent a range of communicable and non-communicable diseases. Probiotic interventions administered during pregnancy and breastfeeding offer a unique opportunity to influence a range of important maternal and infant outcomes. The aim of the Probiotics in Pregnancy Study (PiP Study) is to assess if supplementation by the probiotic Lactobacillus rhamnosus HN001 administered to women from early pregnancy and while breastfeeding can reduce the rates of infant eczema and atopic sensitisation at 1 year, and maternal gestational diabetes mellitus, bacterial vaginosis and Group B Streptococcal vaginal colonisation before birth, and depression and anxiety postpartum. METHODS/DESIGN: The PiP Study is a two-centre, randomised, double-blind placebo-controlled trial in Wellington and Auckland, New Zealand. Four hundred pregnant women expecting infants at high risk of allergic disease will be enrolled in the study at 14-16 weeks gestation and randomised to receive either Lactobacillus rhamnosus HN001 (6 × 10(9) colony-forming units per day (cfu/day)) or placebo until delivery and then continuing until 6 months post-partum, if breastfeeding. Primary infant outcomes are the development and severity of eczema and atopic sensitisation in the first year of life. Secondary outcomes are diagnosis of maternal gestational diabetes mellitus, presence of bacterial vaginosis and vaginal carriage of Group B Streptococcus (at 35-37 weeks gestation). Other outcome measures include maternal weight gain, maternal postpartum depression and anxiety, infant birth weight, preterm birth, and rate of caesarean sections. A range of samples including maternal and infant faecal samples, maternal blood samples, cord blood and infant cord tissue samples, breast milk, infant skin swabs and infant buccal swabs will be collected for the investigation of the mechanisms of probiotic action. DISCUSSION: The study will investigate if mother-only supplementation with Lactobacillus rhamnosus HN001 in pregnancy and while breastfeeding can reduce rates of eczema and atopic sensitisation in infants by 1 year, and reduce maternal rates of gestational diabetes mellitus, bacterial vaginosis, vaginal carriage of Group B Streptococcus before birth and maternal depression and anxiety postpartum. TRIAL REGISTRATION: Australian New Zealand Clinical Trials Registration: ACTRN12612000196842. Date Registered: 15/02/12.

RESUMEN

BACKGROUND: Maternal perception of decreased fetal movements is a specific indicator of fetal compromise, notably in the context of poor fetal growth. There is currently no agreed numerical definition of decreased fetal movements, with the subjective perception of a decrease on the part of the mother being the most significant definition clinically. Both qualitative and quantitative aspects of fetal activity may be important in identifying the compromised fetus.Yet, how pregnant women perceive and describe fetal activity is under-investigated by qualitative means. The aim of this study was to explore normal fetal activity, through first-hand descriptive accounts by pregnant women. METHODS: Using qualitative descriptive methodology, interviews were conducted with 19 low-risk women experiencing their first pregnancy, at two timepoints in their third trimester. Interview transcripts were later analysed using qualitative content analysis and patterns of fetal activity identified were then considered along-side the characteristics of the women and their birth outcomes. RESULTS: This paper focuses on a novel finding; the description by pregnant women of fetal behaviour indicative of hunger and satiation. Full findings will be presented in later papers. Most participants (74% 14 of 19) indicated mealtimes were a time of increased fetal activity. Eight participants provided detailed descriptions of increased activity around meals, with seven (37% 7 of 19) of these specifying increased fetal activity prior to meals or in the context of their own hunger. These movements were interpreted as a fetal demand for food often prompting the mother to eat. Interestingly, the women who described increased fetal activity in the context of hunger subsequently gave birth to smaller infants (mean difference 364 gm) than those who did not describe a fetal response to hunger. CONCLUSIONS: Food seeking behaviour may have a pre-birth origin. Maternal-fetal interaction around mealtimes could constitute an endocrine mediated communication, in the interests of maintaining optimal intrauterine conditions. Further research is warranted to explore this phenomenon and the potential influence of feeding on the temporal organisation of fetal activity in relation to growth.

RESUMEN

BACKGROUND: Research-informed fetal monitoring guidelines recommend intermittent auscultation (IA) for fetal heart monitoring for low-risk women. However, the use of cardiotocography (CTG) continues to dominate many institutional maternity settings. METHODS: A mixed methods intervention study with before and after measurement was undertaken in one secondary level health service to facilitate the implementation of an initiative to encourage the use of IA. The intervention initiative was a decision-making framework called Intelligent Structured Intermittent Auscultation (ISIA) introduced through an education session. RESULTS: Following the intervention, medical records review revealed an increase in the use of IA during labour represented by a relative change of 12%, with improved documentation of clinical findings from assessments, and a significant reduction in the risk of receiving an admission CTG (RR 0.75, 95% CI, 0.60-0.95, p = 0.016). CONCLUSION: The ISIA informed decision-making framework transformed the practice of IA and provided a mechanism for knowledge translation that enabled midwives to implement evidence-based fetal heart monitoring for low risk women.

RESUMEN

INTRODUCTION: Birth is a normal physiological process, and many women want a natural birth. Women use a range of non-pharmacological pain relief methods to reduce labour pain intensity, to help manage labour pain and to induce relaxation. The purpose of this study was to explore the experiences of women using Virtual Reality as a non-pharmacological method of pain relief in labour. Virtual Reality has been shown to be an effective distraction technique in other acute pain settings which also reduces anxiety. METHODS: This study conducted qualitative in-depth interviews postnatally with women who used Virtual Reality in labour. Thematic analysis was used to analyse the qualitative data. RESULTS: Nineteen women used Virtual Reality in labour. Results from interviews with nineteen women in the postnatal period identified three main themes: impact of virtual reality on experience of labour, managing the pain of labour and challenges of using virtual reality in labour. CONCLUSION: This study identified that Virtual Reality was effective as a relaxation technique and helped in pain management by the use of self-efficacy techniques. Women in this study also identified preferred virtual environments specifically to use during labour and birth. This study provides a unique and original contribution to the field of Virtual Reality in labour and birth. It also identifies Virtual Reality as an acceptable and positive experience in the management of anxiety and labour pain.

RESUMEN

PROBLEM: COVID-19 guidance from professional and health organisations created uncertainty leading to professional and personal stress impacting on midwives providing continuity of care in New Zealand (NZ). The COVID-19 pandemic resulted in massive amounts of international and national information and guidance. This guidance was often conflicting and not suited to New Zealand midwifery. AIM: To examine and map the national and international guidance and information provided to midwifery regarding COVID-19 and foreground learnt lessons for future similar crises. METHODS: A systematic scoping review informed by Arksey and O'Malley's five-stage framework. A range of sources from grey and empirical literature was identified and 257 sources included. FINDINGS: Four categories were identified and discussed: (1) guidance for provision of maternity care in the community; (2) guidance for provision of primary labour and birth care; (3) Guidance for midwifery care to women/wahine with confirmed/suspected COVID-19 infection, including screening processes and management of neonates of infected women/wahine (4) Guidance for midwives on protecting self and own families and whanau (extended family) from COVID-19 exposure. CONCLUSION: Guidance was mainly targeted and tailored for hospital-based services. This was at odds with the NZ context, where primary continuity of care underpins practice. It is evident that those providing continuity of care constantly needed to navigate an evolving situation to mitigate interruptions and restrictions to midwifery care, often without fully knowing the personal risk to themselves and their own families. A key message is the need for a single source of evidence-based guidance, regularly updated and timestamped to show where advice changes over time.

RESUMEN

BACKGROUND: There is an overuse of cardiotocography for intrapartum fetal monitoring for low-risk women in high-income countries, despite recommendations from evidence-based guidelines. AIM: To understand why midwives use cardiotocography for low-risk women despite evidence-based recommendations and to understand the roles of the cardiotocograph machine. METHOD: This qualitative study used focus groups for data collection. Thirty-one midwives and three student midwives participated from four different countries: New Zealand, Australia, Denmark, and Norway. Constant comparative analysis, informed by an actor-network theory framework, was the method of data analysis. FINDINGS: Cardiotocography was multifaceted and influenced all attendants in the birth environment. The cardiotocograph itself is assigned different roles within the complex networks surrounding childbirth. The cardiotocograph's roles were as a babysitter, the midwives' partner, an agent of shared responsibility, a protector that 'covers your back', a disturber of normal birth, and a requested guest. DISCUSSION: The application of the actor-network theory enabled us to understand how midwives perceive cardiotocography. The assigned roles of the cardiotocograph shape its everyday use more than evidence-based guidelines. Discussion of these inconsistencies must inform the use of cardiotocography in the care of women with low-risk pregnancies. CONCLUSION: We found that the cardiotocograph is a multifaceted actant that influences practice by performing different roles. Drawing on this study, we suggest that actor-network theory could be a helpful theoretical perspective to critically reflect upon the increasing use of technologies within maternity care.

RESUMEN

OBJECTIVE: In most high-income countries, the cardiotocography and handheld Doppler device have replaced the Pinard stethoscope for intrapartum foetal monitoring. As a result, the skills required to use the Pinard are rapidly disappearing from midwifery. The aim of this study was thus to illuminate the knowledge before it is lost, by exploring the practice, skills and experience of Norwegian midwives familiar with the Pinard for intrapartum foetal monitoring. We included midwives who still regularly use the Pinard in their current practice in a variety of birth settings, and those who used the Pinard in the era prior to the introduction of the CTG. DESIGN: This study followed a qualitative descriptive design based on mainly focus group interviews, but also including one individual interview. The interviews explored the participants` perspective on their practice, skills and experience regarding the use of the Pinard for intrapartum foetal monitoring. Reflexive thematic analysis captured common patterns across the data, and contextualism was used as research paradigm. SETTING AND PARTICIPANTS: In total, 21 midwives with experience using the Pinard for intrapartum foetal monitoring were interviewed. The midwives were either retired and had experience using the Pinard from before the CTG became widespread; worked in an alongside midwifery unit that only oversees low-risk births; or worked in an obstetric unit in a university hospital with an active policy of using the Pinard for intrapartum foetal monitoring. FINDINGS: The analysis resulted in four main themes: "Practice and experience with the Pinard are related to context", "Skills with the Pinard come with work experience", "The Pinard reveals certain characteristics of foetal sound" and "Midwives` experience with the benefits of using the Pinard". The midwives considered the context for using the Pinard for intrapartum foetal monitoring relevant. The e availability of technology and applicable situations for using the Pinard influenced how and when they use the Pinard. They further underpinned training and work experience as important for feeling secure when using the Pinard, and this experience made them recognize normal and abnormal foetal sounds. Defining and characterizing these sounds appeared difficult for the midwives, however, and they hesitated and imitated the sound. The midwives felt that the Pinard is beneficial for both the labouring woman and the midwife, as the Pinard's features bring them closer to the labouring woman and help calm the birth suite. They also felt that the Pinard adds further information about the birth and birth process, such as foetal lie, rotation and descent. KEYCONCLUSIONS: Norwegian midwives' practice, and experiences in using the Pinard for intrapartum foetal monitoring are connected to context as technological development and applicable situations. The midwives explained that knowledge obtained through experience gives them skills to differentiate between normal and abnormal foetal sound characteristics, though they found it difficult to define the characteristics themselves. Using the Pinard stethoscope during birth calms the birth suite and brings the midwife closer to the labouring woman.

RESUMEN

OBJECTIVE: Freedom of movement and choice of positioning in labour and birth is known to enhance physiological processes and positive experiences for women during childbirth. Continuous foetal monitoring technologies that enable mobility in labour for women with complex pregnancies, such as wireless CTG, have been marketed for clinical use in most high resource settings since 2003 but there is a paucity of midwifery literature about its clinical use. The aim of this survey was to determine how often, and for whom, wireless and beltless technologies are being used in maternity settings across Australia and New Zealand and to identify any barriers to their uptake. DESIGN: A survey tool developed by Watson et al. (2018) for use in the United Kingdom was adapted for the Australian/New Zealand context. One Maternity Unit Manager or key midwifery clinician from each of 208 public and private hospitals across Australia and New Zealand was invited by email to participate in an online survey between October 2019 and January 2020. Descriptive statistics were used to describe the characteristics of the facilities and the frequency of availability of the monitors. Free text responses were thematically analysed. FINDINGS: The survey received a high (71%) response rate from a range of public and private hospitals in urban and rural settings. Women's freedom of movement and sense of choice and control in labour were seen by most respondents to be positively influenced by wireless monitoring technology. Most facilities reported having at least one wireless or beltless foetal monitor available, however, results suggest that many women consenting to continuous monitoring still do not have access to technology that enables freedom of movement. KEYCONCLUSIONS: Further research is required to explore the barriers and facilitators to enabling freedom of movement and positioning to all women in childbirth, including those women with complex pregnancies who may consent to continuous foetal monitoring.

RESUMEN

New Zealand's response to COVID-19 was go hard and go early into Level 4 lockdown on 25th March 2020. This rapid response has resulted in low rates of infection and deaths. For New Zealand midwives, the sudden changes to how they work with women and families during pregnancy, birth and postnatally, especially in the community, required unprecedented innovation and adaptation. The volume of information coming from many different sources, and the speed with which it was changing and updating, added further stress to the delivery of a midwifery model of care underpinned by partnership, collaboration, informed choice, safety and relational continuity. Despite the uncertainties, midwives continued their care for women and their families across all settings. In the rapidly changing landscape of the pandemic, news media provided a real time account of midwives' and families' challenges and experiences. This article provides background and discussion of these events and reports on a content analysis of media reporting the impact on the maternity system in New Zealand during the initial surge of the COVID-19 pandemic. We found that the New Zealand midwife was a major influencer and initiator for relational care to occur uninterrupted at the frontline throughout the COVID-19 lockdown, despite the personal risk. The initial 5-week lockdown in March 2020 involved stringent restrictions requiring all New Zealanders, other than essential workers such as midwives, to remain at home. Midwives kept women, their families and communities central to the conversation throughout lockdown whilst juggling their concerns about keeping themselves and their own families safe. Insights gained from the media analysis suggest that despite the significant stress and upheaval experienced by midwives and wahine/women, relational continuity facilitates quality and consistent care that honors women's choices and cultural needs even during situations of national crisis.

RESUMEN

BACKGROUND: A new wireless and beltless monitoring device utilising fetal and maternal electrocardiography (ECG) and uterine electromyography, known as 'non-invasive fetal ECG' (NIFECG) was registered for clinical use in Australia in 2018. The safety and reliability of NIFECG has been demonstrated in controlled settings for short periods during labour. As far as we are aware, at the time our study commenced, this was globally the first trial of such a device in an authentic clinical setting for the entire duration of a woman's labour. METHODS: This study aimed to assess the feasibility of using NIFECG fetal monitoring for women undergoing continuous electronic fetal monitoring during labour and birth. Women were eligible to participate in the study if they were at 36 weeks gestation or greater with a singleton pregnancy, planning to give birth vaginally and with obstetric indications as per local protocol (NSW Health Fetal Heart Rate Monitoring Guideline GL2018_025. 2018) for continuous intrapartum fetal monitoring. Written informed consent was received from participating women in antenatal clinic prior to the onset of labour. This single site clinical feasibility study took place between January and July 2020 at the Royal Hospital for Women in Sydney, Australia. Quantitative and qualitative data were collected to inform the analysis of results using the NASSS (Non-adoption, Abandonment, Scale up, Spread and Sustainability) framework, a validated tool for analysing the implementation of new health technologies into clinical settings. RESULTS: Women responded positively about the comfort and freedom of movement afforded by the NIFECG. Midwives reported that when no loss of contact occurred, the device enabled them to focus less on the technology and more on supporting women's physical and emotional needs during labour. Midwives and obstetricians noticed the benefits for women but expressed a need for greater certainty about the reliability of the signal. CONCLUSION: The NIFECG device enables freedom of movement and positioning for labouring women and was well received by women and the majority of clinicians. Whilst measurement of the uterine activity was reliable, there was uncertainty for clinicians in relation to loss of contact of the fetal heart rate. If this can be ameliorated the device shows potential to be used as routinely as cardiotocography (CTG) for fetal monitoring. This is the first time the NASSS framework has been used to synthesise the implementation needs of a health technology in the care of women during labour and birth. Our findings contribute new knowledge about the determinants for implementation of a complex technology in a maternity care setting. TRIAL REGISTRATION: The Universal Trial Number is reU1111-1228-9845 and the Australian and New Zealand Clinical Trial Registration Number is 12619000293167p. Trial registration occurred on the 20 February, 2019. The trial protocol may be viewed at http://www.anzctr.org.au/Trial/Registration/TrialReview.aspx?id=377027.

RESUMEN

We have previously shown that probiotic supplementation with Lactobacillus rhamnosus HN001 (HN001) led to a reduced incidence of gestational diabetes mellitus (GDM). Here we investigate whether HN001 supplementation resulted in alterations in fasting lipids, insulin resistance, or bile acids (BAs) during pregnancy. Fasting plasma samples collected at 24-30 weeks' gestation, from 348 women randomised at 14-16 weeks' gestation to consume daily probiotic HN001 (n = 172) or a placebo (n = 176) were analysed for lipids, insulin, glucose and BAs. Women supplemented with HN001 had lower fasting glucose compared with placebo (p = 0.040), and lower GDM. Significant differences were found in fasting insulin, HOMA-IR, low density lipoprotein-cholesterol (LDL-c), high density lipoprotein (HDL)-c, triglycerides, total cholesterol, and BAs by GDM status. Lower fasting conjugated BAs were seen in women receiving HN001. A significant decrease of glycocholic acid (GCA) was found in older (age ≥ 35) women who received HN001 (p = 0.005), while GDM women showed significant reduced taurodeoxycholic acid (TDCA) (p = 0.018). Fasting conjugated BA was positively correlated with fasting glucose (r = 0.136, p = 0.020) and fasting insulin (r = 0.113, p = 0.036). Probiotic HN001 supplementation decreases conjugated BAs and might play a role in the improvement of glucose metabolism in women with pregnancy.

RESUMEN

BACKGROUND: Intermittent auscultation (IA) is the technique of listening to and counting the fetal heart rate (FHR) for short periods during active labour and continuous cardiotocography (CTC) implies FHR monitoring for longer periods. Although the evidence suggests that IA is the best way to monitor healthy women at low risk of complications, there is no scientific evidence for the ideal device, timing, frequency and duration for IA. We aimed to give an overview of the field, identify and describe methods and practices for performing IA, map the evidence and accuracy for different methods of IA, and identify research gaps. METHODS: We conducted a systematic scoping review following the Joanna Briggs methodology. Medline, EMBASE, Cinahl, Maternity & Infant Care, Cochrane Library, SveMed+, Web of Science, Scopus, Lilacs and African Journals Online were searched for publications up to January 2019. We did hand searches in relevant articles and databases. Studies from all countries, international guidelines and national guidelines from Denmark, United Kingdom, United States, New Zealand, Australia, The Netherlands, Sweden, Denmark, and Norway were included. We did quality assessment of the guidelines according to the AGREEMENT tool. We performed a meta-analysis assessing the effects of IA with a Doppler device vs. Pinard device using methods described in The Cochrane Handbook, and we performed an overall assessment of the summary of evidence using the GRADE approach. RESULTS: The searches generated 6408 hits of which 26 studies and 11 guidelines were included in the review. The studies described slightly different techniques for performing IA, and some did not provide detailed descriptions. Few of the studies provided details of normal and abnormal IA findings. All 11 guidelines recommended IA for low risk women, although they had slightly different recommendations on the frequency, timing, and duration for IA, and the FHR characteristics that should be observed. Four of the included studies, comprising 8436 women and their babies, were randomised controlled trials that evaluated the effect of IA with a Doppler device vs. a Pinard device. Abnormal FHRs were detected more often using the Doppler device than in those using the Pinard device (risk ratio 1.77; 95% confidence interval 1.29-2.43). There were no significant differences in any of the other maternal or neonatal outcomes. Four studies assessed the accuracy of IA findings. Normal FHR was easiest to identify correctly, whereas identifying periodic FHR patterns such as decelerations and saltatory patterns were more difficult. CONCLUSION: Although IA is the recommended method, no trials have been published that evaluate protocols on how to perform it. Nor has any study assessed interrater agreements regarding interpretations of IA findings, and few have assessed to what degree clinicians can describe FHR patterns detected by IA. We found no evidence to recommend Doppler device instead of the Pinard for IA, or vice versa.

RESUMEN

PROBLEM: Decreased fetal movements is a common reason for unscheduled antenatal assessment and is associated with adverse pregnancy outcome. BACKGROUND: Fetal movement counting has not been proven to reduce stillbirths in high-quality studies. AIMS: The aim was to explore a qualitative account of fetal movements in the third trimester as perceived by pregnant women themselves. METHODS: Using qualitative descriptive methodology, interviews were conducted with 19 women experiencing an uncomplicated first pregnancy, at two timepoints in their third trimester. Interview transcripts were later analysed using qualitative content analysis. FINDINGS: Pregnant women described a sustained increase in strength, frequency and variation in types of fetal movements from quickening until 28-32 weeks. Patterns of fetal movement were consistently described as involving increased movement later in the day and as having an inverse relationship to the women's own activity and rest. At term, the most notable feature was increased strength. Kicking and jolting movements decreased whilst pushing and rolling movements increased. DISCUSSION: Maternal descriptions of fetal activity in this study were consistent with other qualitative studies and with ultrasound studies of fetal development. CONCLUSION: Pregnant women observe a complex range of fetal movement patterns, actions and responses that are likely to be consistent with normal development. Maternal perception of a qualitative change in fetal movements may be clinically important and should take precedence over any numeric definition of decreased fetal movement. Midwives may inform women that it is normal to perceive more fetal movement in the evening and increasingly strong movements as pregnancy advances.

RESUMEN

BACKGROUND: Second-degree tears are the most common form of perineal trauma occurring after vaginal birth managed by New Zealand midwives, although little is known about midwives' perineal practice. AIM: The aim of this study was to identify how midwives managed the last second-degree perineal tear they treated and the level to which their practice reflects National Institute for Health and Care Excellence guidelines. METHODS: An (anonymous) online survey was conducted over a six-week period in 2013. New Zealand midwives who self-identified as currently practising perineal management and could recall management of the last second-degree tear they treated were included in the analysis. FINDINGS: Of those invited, 645 (57.1% self-employed, 42.9% employed) were eligible and completed surveys. Self-employed midwives reported greater confidence (88.0% vs 74.4%, p<0.001) and more recent experience (85.1% vs 57.4%, p<0.001) with perineal repair than employed midwives. Midwives who left the last second-degree tear unsutured (7.3%) were more likely to report low confidence (48.9% vs 15.4%, p<0.001) and less recent experience with repair (53.2% vs 24.7%, p<0.001), and were less likely to report a digital-rectal examination (10.6% vs 49.0%, p<0.001), compared to midwives who sutured. Care consistent with evidence-based guidelines (performing a digital-rectal examination, 59.4% vs 49.3% p=0.005; optimal suturing techniques, 62.2% vs 48.7%, p=0.001) was associated with recent perineal education. CONCLUSIONS: Midwives' management of the last second-degree perineal tear is variable and influenced by factors including: employment status, experience, confidence, and perineal education. There is potential for improvement in midwives' management through increased uptake of evidence-based guidelines and through ongoing education.

RESUMEN

The tensions of uncertainty: midwives managing risk in and of their practice. There has been a fundamental shift in past decades in the way midwifery is enacted. The midwifery attributes of skilful practice and conscious alertness seem to have been replaced by the concept of risk with its connotations of control, surveillance and blame. How midwifery manages practice in this risk framework is of concern. Taking a critical realist approach this paper reports on a theoretically and empirically derived model of midwifery undertaken with New Zealand midwives. The model is a three legged birth stool for the midwife which describes how she makes sense of risk in practice. The seat of the stool is being with women and the legs are 'being a professional', 'working the system' and 'working with complexity'. The struts which hold the stool together are 'story telling'. Risk theory is reviewed in light of the empirical study and a theoretical gap of uncertainty and complexity are identified.

RESUMEN

BACKGROUND: Fetal monitoring guidelines recommend intermittent auscultation for the monitoring of fetal wellbeing during labour for low-risk women. However, these guidelines are not being translated into practice and low-risk women birthing in institutional maternity units are increasingly exposed to continuous cardiotocographic monitoring, both on admission to hospital and during labour. When continuous fetal monitoring becomes routinised, midwives and obstetricians lose practical skills around intermittent auscultation. To support clinical practice and decision-making around auscultation modality, the intelligent structured intermittent auscultation (ISIA) framework was developed. AIM: The purpose of this discussion paper is to describe the application of intelligent structured intermittent auscultation in practice. DISCUSSION: The intelligent structured intermittent auscultation decision-making framework is a knowledge translation tool that supports the implementation of evidence into practice around the use of intermittent auscultation for fetal heart monitoring for low-risk women during labour. An understanding of the physiology of the materno-utero-placental unit and control of the fetal heart underpin the development of the framework. CONCLUSION: Intelligent structured intermittent auscultation provides midwives with a robust means of demonstrating their critical thinking and clinical reasoning and supports their understanding of normal physiological birth.
