Weckend M, McCullough K, Duffield C, Bayes S, Davison C. Physiological plateaus during normal labor and birth: A novel definition. Birth 2024. [PMID: 38800984 DOI: 10.1111/birt.12843] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/07/2023] [Revised: 01/24/2024] [Accepted: 05/02/2024] [Indexed: 05/29/2024]
Abstract
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.

Abstract
OBJECTIVE This study aimed to examine maternal and neonatal factors in cesarean deliveries due to dystocia, including cephalopelvic disproportion, latent-phase prolongation, and fetal malposition or malpresentation. Additionally, we sought to compare the differences between the dystocia subgroups. METHOD AND MATERIALS This retrospective case-control study included women who delivered between January 2010 and June 2021 after 37 weeks of pregnancy and underwent abdominal-pelvic CT scans within 5 years before and after delivery. Neonatal factors were extracted from medical charts immediately after delivery. RESULTS Among the 292 women studied, those with cesarean deliveries for dystocia were older (mean ± SD, 34.2 ± 4.27 vs. 32.2 ± 3.8, p-value = 0.002), had higher pre-pregnancy BMI (22.7 ± 3.67 vs. 21.4 ± 3.48, p-value = 0.012) and term-BMI (27.4 ± 3.72 vs. 25.9 ± 3.66, p-value = 0.010), shorter interspinous distance (ISD, the distance between ischial spine) (10.8 ± 0.76 vs. 11.2 ± 0.85 cm, p-value = 0.003), and longer head circumference (HC) (35 ± 1.47 vs. 34.4 ± 1.36 cm, p-value = 0.003) compared to those who had vaginal deliveries. Univariate logistic regression for dystocia revealed associations between HC/maternal height and HC/ISD ratios (OR, 2.02 [95% confidence interval, CI, 1.4 ~ 2.92], 12.13 [3.2 ~ 46.04], respectively). Multivariate logistic analysis indicated that maternal age, ISD, and HC were significant factors for dystocia (OR, 1.11 [95% CI, 1.01 ~ 1.21], 0.49 [0.26 ~ 0.91], 1.53 [1.07 ~ 2.19], respectively). The subgroup with latent-phase prolongation exhibited the lowest birthweight/term-BMI ratio (124 ± 18.8 vs. 113 ± 10.3 vs. 134 ± 19.1, p-value = 0.013). CONCLUSION The HC/ISD ratio emerged as a crucial predictor of dystocia, suggesting that reducing term-BMI could potentially mitigate latent-phase prolongation. Further research assessing the maternal mid-pelvis during pregnancy and labor is warranted, along with efforts to reduce BMI during pregnancy.

Weckend M, McCullough K, Duffield C, Bayes S, Davison C. Failure to progress or just normal? A constructivist grounded theory of physiological plateaus during childbirth. Women Birth 2024; 37:229-239. [PMID: 37867094 DOI: 10.1016/j.wombi.2023.10.003] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/22/2023] [Revised: 10/08/2023] [Accepted: 10/09/2023] [Indexed: 10/24/2023]
Abstract
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.

SEXUAL & REPRODUCTIVE HEALTHCARE 2023; 36:100855. [PMID: 37210774 DOI: 10.1016/j.srhc.2023.100855] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/12/2022] [Revised: 03/30/2023] [Accepted: 05/02/2023] [Indexed: 05/23/2023]
Abstract
OBJECTIVE To identify maternal factors associated with labor dystocia in low-risk nulliparous women. METHODS MEDLINE, Embase, ClinicalTrials.gov, Cochrane, and CINAHL were searched for intervention studies and observational studies published from January 2000 to January 2022. Low-risk was defined as nulliparous women with a singleton, cephalic birth in spontaneous labor at term. Labor dystocia was defined by national or international criteria or treatment. Countries were restricted to OECD members. Two authors independently screened 11,374 titles and abstracts, extracted data, and assessed risk of bias using the Newcastle-Ottawa Scale. Results were presented narratively and by meta-analysis when compatible. RESULTS Seven cohort studies were included. Overall, the certainty of the evidence was moderate. Three studies found that higher maternal age was associated with an increased frequency of labor dystocia (relative risk 1.68; 95% CI 1.43-1.98). Further three studies found that higher maternal BMI was associated with increased frequency of labor dystocia (relative risk 1.20; 95% CI 1.01-1.43). Maternal short stature, fear of childbirth, and high caffeine intake were also associated with an increased frequency of labor dystocia, while maternal physical activity was associated with a decreased frequency. CONCLUSION Maternal factors associated with an increased frequency of labor dystocia were mainly maternal age, physical characteristics, and fear of childbirth. Maternal physical activity was associated with a decreased frequency. Intervention studies targeting these maternal factors would need to be initiated before or early in pregnancy to test the causality of the identified factors and labor dystocia.

Abstract
OBJECTIVE To explore and synthesise women's views and experiences of augmentation of labour with synthetic oxytocin infusion. DESIGN A qualitative evidence synthesis was conducted. The SPIDER acronym was used to develop the search terms and determine the inclusion criteria. Six bibliographic databases: MEDLINE, CINAHL, EMBASE, PsycINFO, Maternity and Infant Care and Web of Science Core Collection were searched in October 2021. Grey literature sources, EThOS, DART-Europe, and the World Health Organization's Clinical Trials Registry were searched, and reference lists of included studies were reviewed. Methodological quality of included studies was assessed using the Evidence for Policy and Practice Information and Co-ordinating (EPPI) Centre assessment tool. Data were synthesised thematically. The confidence of each review finding was assessed using the Grading of Recommendations Assessment, Development and Evaluation-Confidence in the Evidence from Reviews of Qualitative research (GRADE-CERQual). Research ethical approval was not required. SETTING AND PARTICIPANTS Women of any age, parity, and cultural background who underwent augmentation of labour with synthetic oxytocin infusion were included. FINDINGS A total of 9306 citations were retrieved. Twenty-five studies conducted across 14 countries met the inclusion criteria and contributed data. Three principal analytical themes emerged: feeling stuck; past and present shaping the future; and cause and effect of augmentation of labour. The decision to augment women's labour was often performed without their informed consent. Women's views and experiences of augmentation of labour were shaped according to their knowledge, beliefs and support received during labour. Irrespective of the context, women consistently associated augmentation of labour with pain. KEY CONCLUSIONS AND IMPLICATIONS FOR PRACTICE Clinical guidelines on augmentation of labour need to be informed by research that includes women's views and experiences as a main outcome. Future research exploring the experience of augmentation of labour rather than the experience of labour dystocia would be beneficial. Increasing women's awareness and knowledge of augmentation of labour may help to ensure that their informed consent is obtained. Healthcare providers should discuss the effects, side effects and implications of augmentation of labour with women, ideally before labour.

Abstract
Introduction
Since Friedman’s seminal publication on laboring women, numerous publications have sought to define normal labor progress. However, there is paucity of data on contemporary labor cervicometry incorporating both maternal and neonatal outcomes. The objective of this study is to establish intrapartum prediction models of unfavorable labor outcomes using machine-learning algorithms.
Materials and methods
Consortium on Safe Labor is a large database consisting of pregnancy and labor characteristics from 12 medical centers in the United States. Outcomes, including maternal and neonatal outcomes, were retrospectively collected. We defined primary outcome as the composite of following unfavorable outcomes: cesarean delivery in active labor, postpartum hemorrhage, intra-amniotic infection, shoulder dystocia, neonatal morbidity, and mortality. Clinical and obstetric parameters at admission and during labor progression were used to build machine-learning risk-prediction models based on the gradient boosting algorithm.
Results
Of 228,438 delivery episodes, 66,586 were eligible for this study. Mean maternal age was 26.95 ± 6.48 years, mean parity was 0.92 ± 1.23, and mean gestational age was 39.35 ± 1.13 weeks. Unfavorable labor outcome was reported in 14,439 (21.68%) deliveries. Starting at a cervical dilation of 4 cm, the area under receiver operating characteristics curve (AUC) of prediction models increased from 0.75 (95% confidence interval, 0.75–0.75) to 0.89 (95% confidence interval, 0.89–0.90) at a dilation of 10 cm. Baseline labor risk score was above 35% in patients with unfavorable outcomes compared to women with favorable outcomes, whose score was below 25%.
Conclusion
Labor risk score is a machine-learning–based score that provides individualized and dynamic alternatives to conventional labor charts. It predicts composite of adverse birth, maternal, and neonatal outcomes as labor progresses. Therefore, it can be deployed in clinical practice to monitor labor progress in real time and support clinical decisions.

Abstract
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.

Abstract
Background: Augmentation of labour (AOL) is the most common intervention to treat labour dystocia. Previous research reported extensive disparities in AOL rates across countries and institutions. Despite its widespread use, women’s views on and experiences of intrapartum augmentation with infused synthetic oxytocin are limited. Methods: A qualitative evidence synthesis on women’s views and experiences of AOL with synthetic oxytocin after spontaneous onset of labour will be conducted. Qualitative studies and studies employing a mixed methods design, where qualitative data can be extracted separately, will be included, as will surveys with open-ended questions that provide qualitative data. A systematic search will be performed of the databases: MEDLINE, CINAHL, EMBASE, PsycINFO, Maternity and Infant Care and Web of Science Core Collection from the date of inception. The methodological quality of included studies will be assessed using the Evidence for Policy and Practice Information and Co-ordinating Centre’s appraisal tool. A three-stage approach, coding of data from primary studies, development of descriptive themes and generation of analytical themes, will be used to synthesise findings. Confidence in findings will be established by the Grading of Recommendations Assessment, Development and Evaluation-Confidence in the Evidence from Reviews of Qualitative research. Discussion: This qualitative evidence synthesis may provide valuable information on women’s experiences of AOL and contribute to a review of clinical practice guidelines for maternity care providers.

Abstract
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.

Abstract
Background: Augmentation of labour (AOL) is the most common intervention to treat labour dystocia. Previous research reported extensive disparities in AOL rates across countries and institutions. Despite its widespread use, women’s views on and experiences of intrapartum augmentation with infused synthetic oxytocin are limited. Methods: A qualitative evidence synthesis on women’s views and experiences of AOL with synthetic oxytocin after spontaneous onset of labour will be conducted. Qualitative studies and studies employing a mixed methods design, where qualitative data can be extracted separately, will be included, as will surveys with open-ended questions that provide qualitative data. A systematic search will be performed of the databases: MEDLINE, CINAHL, EMBASE, PsycINFO, Maternity and Infant Care and Web of Science Core Collection from the date of inception. The methodological quality of included studies will be assessed using the Evidence for Policy and Practice Information and Co-ordinating Centre’s appraisal tool. A three-stage approach, coding of data from primary studies, development of descriptive themes and generation of analytical themes, will be used to synthesise findings. Confidence in findings will be established by the Grading of Recommendations Assessment, Development and Evaluation-Confidence in the Evidence from Reviews of Qualitative research. Discussion: This qualitative evidence synthesis may provide valuable information on women’s experiences of AOL and contribute to a review of clinical practice guidelines for maternity care providers.

Abstract
INTRODUCTION Obesity is a globally growing problem. Labor dystocia is associated with obstetric complications, especially among obese pregnant women. Previous studies have shown an association between the level of lactate produced by uterine myocytes during contractions and the level of lactate in the amniotic fluid (AFL). A relationship between a high level of AFL and labor dystocia has also been demonstrated. However, it is still unknown whether the observation applies to all women with labor dystocia, regardless of body mass index (BMI). Aims: This study investigated whether there was any difference in the level of AFL in the three BMI groups and whether there was a difference in labor outcomes between high and low AFL in the different groups. MATERIALS AND METHODS This cross-sectional study included 1683 women from three different countries. Healthy nulliparous women in active labor were included, and they were grouped according to BMI as normal weighted (<25), overweight (≥25-29), and obese (≥30), respectively. AFL was categorized as high (≥10.1 mmol/l) and low (<10.1 mmol/l). The main outcome was the frequency of cesarean section. RESULTS No difference in AFL levels was found between the three BMI groups at delivery (mean values of 8.2 vs. 8.3 vs. 8.4 mmol/l, p = .3). Obese women with high AFL had a higher frequency of cesarean section than normal-weighted women (16.2 vs. 20.7 vs. 29.2%). Other risk factors associated with cesarean section varied among the different BMI groups. CONCLUSIONS This study showed no difference in the mean level of AFL between women with different BMIs. Further, high AFL was associated with a higher frequency of cesarean section in all three BMI groups, suggesting that the level of AFL can in the future be used as a predictor of labor outcome among women with labor dystocia despite their BMI.

Abstract
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.

Abstract
BACKGROUND/OBJECTIVE To evaluate the association between the duration of the latent phase of labor and subsequent processes and outcomes. METHODS Secondary analysis of prospectively collected data among 1,189 women with low-risk pregnancies and spontaneous labor. RESULTS Longer latent phase duration was associated with labor dystocia (eg, nulliparous ≥ mean [compared with < mean] aOR 3.95 [2.70-5.79]; multiparous ≥ mean [compared with < mean] aOR 5.45 [3.43-8.65]), interventions to ameliorate dystocia, and epidurals to cope or rest (eg, oxytocin augmentation: nulliparous > 80th% [compared with < 80th%] aOR 6.39 [4.04-10.12]; multiparous ≥ 80th% [compared with < 80th%] aOR 6.35 [3.79-10.64]). Longer latent phase duration was also associated with longer active phase and second stage. There were no associations between latent phase duration and risk for cesarean delivery or postpartum hemorrhage in a practice setting with relatively low rates of primary cesarean. Newborns born to multiparous women with latent phase of labor durations at and beyond the 80th% were more frequently admitted to the NICU (≥80th% [compared with < 80th%] aOR 2.7 [1.22-5.84]); however, two-thirds of these NICU admissions were likely for observation only. CONCLUSIONS Longer duration of the spontaneous latent phase of labor among women with low-risk pregnancies may signal longer total labor processes, leading to an increase in diagnosis of dystocia, interventions to manage dystocia, and epidural use. Apart from multiparous neonatal NICU admission, no other maternal or child morbidity outcomes were elevated with longer duration of the latent phase of labor.

Abstract
Norms used to describe and evaluate the first stage of labor have been historically based upon data from the middle of the twentieth century. More recent data has characterized the normal first stage of labor differently including that the latent phase of labor is longer not transitioning from latent to active labor until about 6 cm of cervical dilation in a majority of women, regardless of parity or whether labor was spontaneous or induced. Additionally, the amount of time that can take for progress to be made in active labor be longer than previously understood. These two factors would lead to a change in management with the diagnosis of arrest of the first stage of labor being made at 6 cm cervical dilation or beyond in the setting of ruptured membranes and no cervical change for at least 4 h of adequate contractions or 6 h of inadequate contractions.

Abstract
Objective In Africa, 80% of women ingest traditional medicine (TM) during pregnancy. Although widely used in Cameroon, no study in has either demonstrated its safety or effectiveness. Hence, we sought to determine the effects of TM ingestions during the peri-partum period on maternal and foetal outcomes. A cohort study was conducted from January to April 2016 in two referral maternity departments of Cameroon. We consecutively enrolled all consenting parturients with gestational age above 28 weeks. We divided them into two groups; exposed and unexposed. The exposure studied was ingestion of TM within 72 h prior to delivery. Variables studied were socio-demographic characteristics, type and frequency of TM ingested and details of labour. Results We enrolled a total of 603 parturients of whom 147 in the exposed group and 456 in the non-exposed group. The most frequently used TM were honey and Triumfetta pentandra A. Ingestion of TM in the peri-paritum period was associated with intra-partum vaginal bleeding, dystocic labour, tachysystole and uterine atony. No adverse neonatal outcome was observed. Overall, these findings could help guide the direction of future research into the safety and potential benefits of peri-partum TM use, as well as serving as a preliminary reference for counselling.

Abstract
AIMS To assess cervical dilation rates of nulliparous and multiparous women in the active first stage of labor and to evaluate significant impact factors. METHODS In a retrospective cohort study between January 2007 and July 2014 at the University Hospital of Zurich in Switzerland, we analyzed 8378 women with singleton pregnancies in vertex presentation with a vaginal delivery at 34+0 to 42+5 gestational weeks. Median cervical dilation rates were calculated and different impact factors evaluated. RESULTS Cervical dilation rates increase during labor progress with faster rates in multiparous compared with nulliparous women (P<0.001). Dilation rates exceed 1 cm/h at a dilatation of 6-7 cm, but are very individual. Accelerating impact factors are multiparity, a greater amount of cervical dilation and fetal occipitoanterior position, whereas the use of epidural anesthesia, a higher fetal weight and head circumference decelerate dilation (P<0.001). CONCLUSION Cervical dilation is a hyperbolic increasing process, with faster dilation rates in multiparous compared to nulliparous women and a reversal point of labor around 6-7 cm, respectively. Besides, cervical dilation is highly individual and affected by several impact factors. The diagnosis of labor arrest or prolonged labor should therefore be based on such rates and on the individual evaluation of every woman.

Abstract
OBJECTIVE to investigate the effects of antenatal reflexology on labour outcomes. DESIGN secondary analysis of a pilot three-armed randomised controlled trial conducted between July 2012 and September 2013. SETTING a large UK inner city hospital maternity department. PARTICIPANTS ninety primiparous women with a singleton pregnancy experiencing low back and / or pelvic girdle pain. INTERVENTIONS six weekly 30-minute reflexology treatments compared to sham (footbath) treatments or usual antenatal care only. MEASUREMENTS labour outcome data including labour onset, duration of the second stage of labour, epidural and Entonox usage, and mode of delivery. Participant feedback was collected prior to each treatment. FINDINGS labour outcomes were collected for 61 women (95.3%) who completed the study. The second stage of labour duration data, available for 42 women (62.5%) who had vaginal births, showed a mean reduction of 44minutes in the reflexology group (73.56minutes; SD= 53.78) compared to the usual care (117.92minutes; SD=56.15) (p<0.05) and footbath groups (117.4minutes; SD=68.54) (p=0.08). No adverse effects were reported. KEY CONCLUSIONS in this trial antenatal reflexology reduced labour duration for primiparous women who had experienced low back and/ or pelvic girdle pain during their pregnancy, compared with usual care and footbaths. IMPLICATIONS FOR PRACTICE reflexology is suitable for use during pregnancy, is safe and enjoyable and may reduce labour duration. Midwives may wish to recommend reflexology to promote normal childbirth and facilitate women centred care. TRIAL REGISTRATION this trial was listed with the International Standard Randomised Controlled Trial Number Register (ISRCTN26607527).
