Physiological plateaus during normal labor and birth: A novel definition.

BACKGROUND: Diagnoses of labor dystocia, and subsequent labor augmentation, make one of the biggest contributions to childbirth medicalization, which remains a key challenge in contemporary maternity care. However, labor dystocia is poorly defined, and the antithetical concept of physiological plateaus remains insufficiently explored. AIM: To generate a definition of physiological plateaus as a basis for further research. METHODS: This qualitative study applied grounded theory methods and comprised interviews with 20 midwives across Australia, conducted between September 2020 and February 2022. Data were coded in a three-phase approach, starting with inductive line-by-line coding, which generated themes and subthemes, and finally, through axial coding. RESULTS: Physiological plateaus represent a temporary slowing of one or multiple labor processes and appear to be common during childbirth. They are reported throughout the entire continuum of labor, typically lasting between a few minutes to several hours. Their etiology/function appears to be a self-regulatory mechanism of the mother-infant dyad. Physiological plateaus typically self-resolve and are followed by a self-resumption of labor. Women with physiological plateaus during labor appear to experience positive birth outcomes. DISCUSSION: Despite appearing to be common, physiological plateaus are insufficiently recognized in contemporary childbirth discourse. Consequently, there seems to be a significant risk of misinterpretation of physiological plateaus as labor dystocia. While findings are limited by the qualitative design and require validation through further quantitative research, the proposed novel definition provides an important starting point for further investigation. CONCLUSION: A better understanding of physiological plateaus holds the potential for a de-medicalization of childbirth through preventing unjustified labor augmentation.

Failure to progress or just normal? A constructivist grounded theory of physiological plateaus during childbirth.

BACKGROUND AND PROBLEM: During childbirth, one of the most common diagnoses of pathology is 'failure to progress', frequently resulting in labour augmentation and intervention cascades. However, failure to progress is poorly defined and evidence suggests that some instances of slowing, stalling and pausing labour patterns may represent physiological plateaus. AIM: To explore how midwives conceptualise physiological plateaus and the significance such plateaus may have for women's labour trajectory and birth outcome. METHODS: Twenty midwives across Australia participated in semi-structured interviews between September 2020 and February 2022. Constructivist grounded theory methodology was applied to analyse data, including multi-phasic coding and application of constant comparative methods, resulting in a novel theory of physiological plateaus that is firmly supported by participant data. FINDINGS: This study found that the conceptualisation of plateauing labour depends largely on health professionals' philosophical assumptions around childbirth. While the Medical Dominant Paradigm frames plateaus as invariably pathological, the Holistic Midwifery Paradigm acknowledges plateaus as a common and valuable element of labour that serves a self-regulatory purpose and results in good birth outcomes for mother and baby. DISCUSSION: Contemporary medicalised approaches in maternity care, which are based on an expectation of continuous labour progress, appear to carry a risk for a misinterpretation of physiological plateaus as pathological. CONCLUSION: This study challenges the widespread bio-medical conceptualisation of plateauing labour as failure to progress, encourages a renegotiation of what can be considered healthy and normal during childbirth, and provides a stimulus to acknowledge the significance of childbirth philosophy for maternity care practice.

Physiological plateaus during normal labor and birth: A scoping review of contemporary concepts and definitions.

BACKGROUND: Physiological plateaus (slowing, stalling, pausing) during normal labor and birth have been reported for decades, but have received limited attention in research and clinical practice. To date, heterogeneous conceptualizations and terminology have impeded effective communication and research in this area, raising concern as to whether some physiological plateaus might be misinterpreted as dystocia. To address this issue, we provide a point of orientation, mapping contemporary concepts, and terminologies of physiological plateaus during normal labor and birth. METHODS: We conducted a scoping review, considering published and unpublished reports of physiological plateaus, reported in any language, between 1990 and 2021. Database searches of CINAHL, EMBASE, Emcare, MIDIRS, MEDLINE, Scopus, and Open Grey yielded 1,953 records, with an additional 35 reports identified by hand searching. In total, 43 reports from eleven countries were included in this scoping review. RESULTS: Conceptualizations of physiological plateaus are heterogeneous and can be allocated to six conceptual groups: cervical reversal or recoil, plateaus, lulls during transition, "rest and be thankful" stage, deceleration phase, and latent phases. Across included material, we identified over 60 different terms referring to physiological plateaus. Overall, physiological plateaus are reported across the entire continuum of normal labor and birth. CONCLUSIONS: Physiological plateaus may be an essential mechanism of self-regulation of the mother-infant dyad, facilitating feto-maternal adaptation and preventing maternal and fetal distress during labor and birth.

Learning objectives of cultural immersion programs: A scoping review.

BACKGROUND: Cultural immersion as a learning activity provides students with the opportunity to experience diversity and develop cultural safety. Both, 'Study Abroad Programs' and 'Internationalisation at Home' (IaH) aim to provide a cultural immersion experience for students. However, explicit learning objectives are essential for quality pedagogy and for students to develop cultural safety from their learning experience. OBJECTIVE: To identify the learning objectives of study abroad and Internationalisation at Home (IaH) programs in higher education health profession programs. DESIGN: A scoping review was undertaken according to recommendations by the Joanna Briggs Institute (Peters et al., 2020) and PRISMA guidelines. DATA SOURCES: The electronic databases CINAHL, MEDLINE, PsychINFO and PubMed and were searched in November 2019 and updated September 2020. The search was limited to qualitative studies, text and opinion pieces, English language, published between 2015 and 2019. REVIEW METHODS: Inclusion criteria using the participants, concept, and context (PCC framework) was utilised and search terms such as study abroad and Internationalisation at Home were combined with learning objectives to identify articles. The articles were screened for eligibility by title, abstract, and full text review by two independent reviewers. A data extraction tool was utilised to extract and synthesise data into categories that represent the core learning objectives of cultural immersion programs reviewed. RESULTS: Fourteen of the 66 initially identified studies were included in this scoping review. Qualitative synthesis yielded five broad categories of learning objectives used in cultural immersion programs: cultural competence, internationalisation, pedagogy, collegiality, and personal growth. CONCLUSION: A minimum set of essential learning outcomes was derived from this review that will be of interest to developers and implementers of cultural immersion programs.

Exploring concepts and definitions of plateaus during normal labor and birth: a scoping review protocol.

OBJECTIVE: In this scoping review, contemporary concepts and definitions of phenomena during normal labor and birth, wherein the process appears to plateau (slow, stall, or pause) but remains within physiological limits, will be mapped. INTRODUCTION: During labor and birth, it is frequently perceived as pathological if contractions, cervical dilation, or fetal descent plateau. However, there is evidence to suggest that some plateaus during labor may be physiological, and a variety of concepts and terms refer to this phenomenon. Where a physiological plateau is perceived as pathological arrest, this may contribute to undue interventions, such as augmentation of labor. Therefore, it is important to advance understanding of physiological labor patterns, including potentially physiological labor plateaus. INCLUSION CRITERIA: Publications mentioning any plateaus of the processes of normal human labor and birth will be considered. This may also include phenomena where labor is perceived to "reverse," for example, a closing cervix or a rise of the presenting fetal part. Publications where plateaus are defined as pathological will be excluded. METHODS: All types of evidence, published and unpublished, will be considered. The search strategy will be applied to the databases MEDLINE, Embase, MIDIRS, Emcare, CINAHL, and Scopus, and will be limited to the past 30 years. Gray literature will be searched via Open Grey, reference list screening, and contacting authors. Data extraction will comprise information on concept boundaries, terminology, precedents, consequences, concept origin, and types of evidence that report this phenomenon. Results will be presented in tabular, diagrammatical, and narrative manner.

Association between increased antenatal vaginal pH and preterm birth rate: a systematic review.

Background Worldwide, 14.9 million infants (11%) are born preterm each year. Up to 40% of preterm births (PTBs) are associated with genital tract infections. The vaginal pH can reflect changes in the vaginal milieu and, if elevated, indicates an abnormal flora or infection. Objective The aim of the study was to investigate whether an increased antenatal vaginal pH >4.5 in pre-labour pregnant women is associated with an increased PTB rate <37 completed weeks gestation. Search strategy Key databases included SCOPUS, EMBASE, MEDLINE, PsycInfo and the Cochrane Central Register of Controlled Trials, complemented by hand search, up to January 2017. Selection criteria Primary research reporting vaginal pH assessment in pre-labour pregnant women and PTB rate. Data collection and analysis Data extraction and appraisal were carried out in a pre-defined standardised manner, applying the Newcastle-Ottawa scale (NOS) and Cochrane risk of bias tool. Analysis included calculation of risk difference (RD) and narrative synthesis. It was decided to abstain from pooling of the studies due to missing information in important moderators. Main results Of 986 identified records, 30 were included in the systematic review. The risk of bias was considered mostly high (40%) or moderate (37%). Fifteen studies permitted a calculation of RD. Of these, 14 (93%) indicated a positive association between increased antenatal vaginal pH and PTB (RD range: 0.02-0.75). Conclusion An increased antenatal vaginal pH >4.5 may be associated with a higher risk for PTB. It is recommended to conduct a randomised controlled trial (RCT) to investigate the effectiveness of antenatal pH screening to prevent PTB. Tweetable abstract Pregnant women with an increased vaginal pH >4.5 may be at higher risk to experience preterm birth.

A concept analysis of the term migrant women in the context of pregnancy.

AIM: This paper explores the concept of migrant women as used in European healthcare literature in context of pregnancy to provide a clearer understanding of the concept for use in research and service delivery. METHODS: Walker and Avant's method of concept analysis. RESULTS: The literature demonstrates ambiguity around the concept; most papers do not provide an explicit or detailed definition of the concept. They include the basic idea that women have moved from an identifiable region/country to the country in which the research is undertaken but fail to acknowledge adequately the heterogeneity of migrant women. The paper provides a definition of the concept as a descriptive theory and argues that research must include a clear definition of the migrant specific demographics of the women. This should include country/region of origin and host, status within the legal system of host country, type of migration experience, and length of residence. CONCLUSION: There is a need for a more systematic conceptualization of the idea of migrant women within European literature related to pregnancy experiences and outcomes to reflect the heterogeneity of this concept. To this end, the schema suggested in this paper should be adopted in future research.
