Changes in Salivary Oxytocin Level of Term Pregnant Women after Aromatherapy Footbath for Spontaneous Labor Onset: A Non-Randomized Experimental Study.

BACKGROUND: Aromatherapy is usually used to stimulate labor. However, its specific physiological effects have been scarcely examined. We evaluated whether an aromatherapy footbath increases oxytocin levels in term pregnant women. METHODS: In this quasi-experimental study, low-risk term pregnant women in Japan underwent aromatherapy using a footbath (1) infused with clary sage and lavender essential oils, (2) infused with jasmine oil, or (3) with no infused oils (control group). The primary outcome was the salivary oxytocin level. The secondary outcomes were uterine contractions and cortisol levels. RESULTS: In the clary sage and lavender group (n = 28), the oxytocin level increased significantly after the footbath (p = 0.035). The jasmine group (n = 27) and control group (n = 27) exhibited trends toward a respective increase and decrease in the oxytocin level; however, the changes in the oxytocin levels between the clary sage and lavender group and the control group showed no significance difference. There were no significant differences in the changes in the uterine contractions and cortisol levels between the experiment and control groups. CONCLUSIONS: The changes in the oxytocin levels in the clary sage and lavender group did not differ significantly with those in the control group, possibly because of the small sample size. Further studies are required to examine the effects of repeated aromatherapy footbaths to stimulate labor.

Intrapartum and neonatal mortality in low-risk term women in midwife-led care and obstetrician-led care at the onset of labor: A national matched cohort study.

INTRODUCTION: Midwife-led models of care have been the subject of debate for many years. We conducted a study to compare intrapartum and neonatal mortality rates in midwife-led (primary) vs obstetrician-led (secondary) care at the onset of labor in low-risk term women. MATERIAL AND METHODS: We performed an unmatched and a propensity score matched cohort study using data from the national perinatal audit registry (PAN) and from the national perinatal registry (PERINED) of the Netherlands. We included women with singleton pregnancies (without congenital anomalies or antepartum fetal death) who gave birth at term between 2010 and 2012. We excluded the following major risk factors: non-vertex position of the fetus, previous cesarean birth, hypertension, diabetes mellitus, prolonged rupture of membranes (≥24 hours), vaginal bleeding in the second half of pregnancy, nonspontaneous start of labor and post-term pregnancy (≥42 weeks). The primary outcome was intrapartum or neonatal mortality up to 28 days after birth. Secondary outcome measures were mode of delivery and a 5-minute Apgar score <7. RESULTS: We included 259 211 women. There were 100/206 642 (0.48‰) intrapartum and neonatal deaths in the midwife group and 23/52 569 (0.44‰) in the obstetrician group (odds ratio [OR] 1.11, 95% CI 0.70-1.74). Propensity score matched analysis showed mortality rates of 0.49‰ (26/52 569) among women in midwife-led care and 0.44‰ (23/52 569) for women in obstetrician-led care (OR 1.13, 95% CI 0.65-1.98). In the midwife group there were significantly lower rates of vaginal instrumental deliveries (8.4% vs 13.0%; matched OR 0.65, 95% CI 0.62-0.67) and intrapartum cesarean sections (2.6% vs 8.2%; matched OR 0.32, 95% CI 0.30-0.34), and fewer neonates with low Apgar scores (<7 after 5 minutes) (0.69% vs 1.11%; matched OR 0.61, 95% CI 0.53-0.69). CONCLUSIONS: Among low-risk term women, there were comparable intrapartum and neonatal mortality rates for women starting labor in midwife-led vs obstetrician-led care, with lower intervention rates and fewer low Apgar scores in the midwife group.

Oxytocin levels in low-risk primiparas following breast stimulation for spontaneous onset of labor: a quasi-experimental study.

BACKGROUND: Breast stimulation is performed to self-induce labor. However, there are apparently no reports on hormonal evaluation during stimulation for consecutive days in relation to induction effect. We evaluated the salivary oxytocin level following 3 consecutive days of own breast stimulation for 1 h each day compared with no breast stimulation. METHODS: We used a quasi-experimental design. The participants were low-risk primiparas between 38 and 39 gestational weeks. Eight saliva samples per participant were collected at preintervention and 30, 60, and 75 min postintervention on the first and third days. The primary outcome was change in the salivary oxytocin level on the third day after 3 consecutive days of breast stimulation for 1 h each day compared with no breast stimulation. The secondary outcomes were the rate of spontaneous labor onset and negative events including uterine hyperstimulation and abnormal fetal heart rate. RESULTS: Between February and September 2016, 42 women were enrolled into the intervention group (n = 22) or control group (n = 20). As there were differences in the basal oxytocin levels between the 2 groups, to estimate the change in the oxytocin level from baseline, we used a linear mixed model with a first-order autoregressive (AR1) covariance structure. The dependent variable was change in the oxytocin level from baseline. The independent variables were gestational weeks on the first day of intervention, age, education, rs53576 and rs2254298, group, time point, and interaction of group and time. After Bonferroni correction, the estimated change in the mean oxytocin level at 30 min on the third day was significantly higher in the intervention group (M = 20.2 pg/mL, SE = 26.2) than in the control group (M = - 44.4 pg/mL, SE = 27.3; p = 0.018). There was no significant difference in the rate of spontaneous labor onset. Although there were no adverse events during delivery, uterine tachysystole occurred in 1 case during the intervention. CONCLUSIONS: The estimated change in the mean oxytocin level was significantly higher 30 min after breast stimulation on the third day. Thus, consecutive breast stimulation increased the salivary oxytocin level. Repeated stimulations likely increase the oxytocin level.

An Assessment of the Effects of Hydrotherapy During the Active Phase of Labor on the Labor Process and Parenting Behavior.

This study was conducted to assess the effect on labor process and parenting behavior of hydrotherapy applied during the active phase of labor. This quasi-experimental study was conducted by using an equivalent comparison group (n = 40). The participants in the experimental group whose cervical dilation was 5 cm were taken to the hydrotherapy tub. This application continued until cervical dilation reached 10 cm. The Participants Questionnaire, The Birth Follow-up Questionnaire, The Postpartum ]collection tools. The duration of the active phase and second stage of labor was extremely short in the experimental group in comparison with the equivalent comparison group (p = .001). The Visual Analogue Scale (VAS) scores of the experimental group were lower than those of the equivalent comparison group when cervical dilation was 6 cm and 10 cm (p = .001). The experimental group also displayed more positive parenting behavior and positive labor feeling (p = .001).

Decision Making about Hospital Arrival among Low-Risk Nulliparous Women after Spontaneous Labor Onset at Home.

INTRODUCTION: Postponing hospital admission until the active phase of labor is a recommended strategy to safely reduce the incidence of primary cesarean births. Success of this strategy depends on women's decisions about when to transfer from home to the hospital, a process that is largely absent from research about childbirth. This study aimed to determine the decision-making criteria used by women about when to go to the hospital after the self-identification of labor onset at home. METHODS: A qualitative study was conducted at an academic medical center with a sample of 21 nulliparous women who went into spontaneous labor at home and had term, singleton, and vertex-presentation births. The purposive sample consisted of women who decided to stay at home or go to the hospital in early labor. Birth narratives from in-depth interviews conducted in the postpartum period using a semistructured interview guide were subjected to content analysis. The verbatim transcriptions of the interviews were coded and categorized into a set of decision criteria. RESULTS: Criteria used by women in deciding to go to the hospital or stay at home in early labor included the degree of certainty with the self-identification of labor onset, ability to cope with labor pain, influence of social network members, health care provider advice, and concerns about travel to the hospital. Perception of childbirth risk and the need for reassurance about the normalcy of symptoms and fetal well-being also influenced women's decisions. DISCUSSION: Women use a common set of criteria in deciding when to arrive at the hospital during labor. Antenatal education and telephone triage interventions that incorporate the considerations of women deciding to seek or delay hospital admission in childbirth may facilitate health seeking in more advanced labor. Symptom recognition education about early labor onset and progression could reduce decisional uncertainty.

Massage, reflexology and other manual methods for pain management in labour.

BACKGROUND: Many women would like to avoid pharmacological or invasive methods of pain management in labour, and this may contribute towards the popularity of complementary methods of pain management. This review examined the evidence currently available on manual methods, including massage and reflexology, for pain management in labour. This review is an update of the review first published in 2012. OBJECTIVES: To assess the effect, safety and acceptability of massage, reflexology and other manual methods to manage pain in labour. SEARCH METHODS: For this update, we searched Cochrane Pregnancy and Childbirth's Trials Register (30 June 2017), the Cochrane Central Register of Controlled Trials (CENTRAL; 2017, Issue 6), MEDLINE (1966 to 30 June 2017, CINAHL (1980 to 30 June 2017), the Australian New Zealand Clinical Trials Registry (4 August 2017), Chinese Clinical Trial Registry (4 August 2017), ClinicalTrials.gov, (4 August 2017), the National Center for Complementary and Integrative Health (4 August 2017), the WHO International Clinical Trials Registry Platform (ICTRP) (4 August 2017) and reference lists of retrieved trials. SELECTION CRITERIA: We included randomised controlled trials comparing manual methods with standard care, other non-pharmacological forms of pain management in labour, no treatment or placebo. We searched for trials of the following modalities: massage, warm packs, thermal manual methods, reflexology, chiropractic, osteopathy, musculo-skeletal manipulation, deep tissue massage, neuro-muscular therapy, shiatsu, tuina, trigger point therapy, myotherapy and zero balancing. We excluded trials for pain management relating to hypnosis, aromatherapy, acupuncture and acupressure; these are included in other Cochrane reviews. DATA COLLECTION AND ANALYSIS: Two review authors independently assessed trial quality, extracted data and checked data for accuracy. We contacted trial authors for additional information. We assessed the quality of the evidence using the GRADE approach. MAIN RESULTS: We included a total of 14 trials; 10 of these (1055 women) contributed data to meta-analysis. Four trials, involving 274 women, met our inclusion criteria but did not contribute data to the review. Over half the trials had a low risk of bias for random sequence generation and attrition bias. The majority of trials had a high risk of performance bias and detection bias, and an unclear risk of reporting bias. We found no trials examining the effectiveness of reflexology.MassageWe found low-quality evidence that massage provided a greater reduction in pain intensity (measured using self-reported pain scales) than usual care during the first stage of labour (standardised mean difference (SMD) -0.81, 95% confidence interval (CI) -1.06 to -0.56, six trials, 362 women). Two trials reported on pain intensity during the second and third stages of labour, and there was evidence of a reduction in pain scores in favour of massage (SMD -0.98, 95% CI -2.23 to 0.26, 124 women; and SMD -1.03, 95% CI -2.17 to 0.11, 122 women). There was very low-quality evidence showing no clear benefit of massage over usual care for the length of labour (in minutes) (mean difference (MD) 20.64, 95% CI -58.24 to 99.52, six trials, 514 women), and pharmacological pain relief (average risk ratio (RR) 0.81, 95% CI 0.37 to 1.74, four trials, 105 women). There was very low-quality evidence showing no clear benefit of massage for assisted vaginal birth (average RR 0.71, 95% CI 0.44 to 1.13, four trials, 368 women) and caesarean section (RR 0.75, 95% CI 0.51 to 1.09, six trials, 514 women). One trial reported less anxiety during the first stage of labour for women receiving massage (MD -16.27, 95% CI -27.03 to -5.51, 60 women). One trial found an increased sense of control from massage (MD 14.05, 95% CI 3.77 to 24.33, 124 women, low-quality evidence). Two trials examining satisfaction with the childbirth experience reported data on different scales; both found more satisfaction with massage, although the evidence was low quality in one study and very low in the other.Warm packsWe found very low-quality evidence for reduced pain (Visual Analogue Scale/VAS) in the first stage of labour (SMD -0.59, 95% CI -1.18 to -0.00, three trials, 191 women), and the second stage of labour (SMD -1.49, 95% CI -2.85 to -0.13, two trials, 128 women). Very low-quality evidence showed reduced length of labour (minutes) in the warm-pack group (MD -66.15, 95% CI -91.83 to -40.47; two trials; 128 women).Thermal manual methodsOne trial evaluated thermal manual methods versus usual care and found very low-quality evidence of reduced pain intensity during the first phase of labour for women receiving thermal methods (MD -1.44, 95% CI -2.24 to -0.65, one trial, 96 women). There was a reduction in the length of labour (minutes) (MD -78.24, 95% CI -118.75 to -37.73, one trial, 96 women, very low-quality evidence). There was no clear difference for assisted vaginal birth (very low-quality evidence). Results were similar for cold packs versus usual care, and intermittent hot and cold packs versus usual care, for pain intensity, length of labour and assisted vaginal birth.Music One trial that compared manual methods with music found very low-quality evidence of reduced pain intensity during labour in the massage group (RR 0.40, 95% CI 0.18 to 0.89, 101 women). There was no evidence of benefit for reduced use of pharmacological pain relief (RR 0.41, 95% CI 0.16 to 1.08, very low-quality evidence).Of the seven outcomes we assessed using GRADE, only pain intensity was reported in all comparisons. Satisfaction with the childbirth experience, sense of control, and caesarean section were rarely reported in any of the comparisons. AUTHORS' CONCLUSIONS: Massage, warm pack and thermal manual methods may have a role in reducing pain, reducing length of labour and improving women's sense of control and emotional experience of labour, although the quality of evidence varies from low to very low and few trials reported on the key GRADE outcomes. Few trials reported on safety as an outcome. There is a need for further research to address these outcomes and to examine the effectiveness and efficacy of these manual methods for pain management.

Effects of breast stimulation for spontaneous onset of labor on salivary oxytocin levels in low-risk pregnant women: A feasibility study.

OBJECTIVES: This preliminary study aimed to 1) determine changes in the salivary oxytocin (OT) level during breast stimulation for promoting the spontaneous onset of labor in low-risk term pregnancies, and 2) clarify the feasibility of the breast stimulation intervention protocol in terms of practicality and acceptability. METHODS: We used a single arm trial design. Sixteen low-risk pregnant women between 38 and 40 weeks of gestation with cephalic presentation participated. They performed breast stimulation for 3 days with an attendant midwife in a single maternity hospital. Each breast was stimulated for 15 minutes for a total of 1 hour per day. Saliva was collected 10 minutes before the intervention and 15, 30, 60, 75, and 90 minutes after the intervention, yielding 18 samples per woman. RESULTS: Among a total of 282 saliva samples from the 16 participants, OT level was measured in 142 samples (missing rate: 49.6%). The median OT level showed the highest values on day 3 of the breast stimulation, with a marked increase 30 min after the intervention. In the mixed models after multiple imputation for missing data, the OT level on the first day of intervention was significantly lower than that on the third day of intervention. Fatigue from breast stimulation decreased on subsequent days, and most of the women (75%) felt no discomfort with the protocol. Uterine hyperstimulation was not observed. CONCLUSION: Following a 3-day breast stimulation protocol for spontaneous onset of labor, the mean OT level showed the highest values on day 3. The breast stimulation intervention protocol showed good feasibility in terms of practicality and acceptability among the pregnant women. Additional large-scale studies are warranted to confirm the protocol's effectiveness.

Comparing Different Partograph Designs for Use in Standard Labor Care: A Pilot Randomized Trial.

Backgound Partographs are used in many labour settings to provide a pictorial overview of a woman's cervical dilation pattern in the first stage of labor and to alert clinicians to slow progress possibly requiring intervention. Recent reviews called for large trials to establish the efficacy of partographs to improve birth outcomes whilst highlighting issues of clinician compliance with use. Previous studies have also reported issues with participant recruitment related to concerns regarding the possibility of a longer labour. Objectives We sought to compare a standard partograph with an action line, to a newly designed partograph with a stepped line, to determine the feasibility of recruitment to a larger clinical trial. Methods A pragmatic, single-blind randomised trial wherein low-risk, nulliparous women in spontaneous labour at term were randomized to an action-line or stepped-line partograph. First stage labour management was guided by the allocated partograph. Primary outcomes included the proportion of eligible women recruited, reasons for failed recruitment and compliance with partograph use. Secondary outcomes included rates of intervention, mode of birth, maternal and neonatal outcomes. Results Of the 384 potentially eligible participants, 38% (149/384) were approached. Of these 77% (116/149) consented, with 85% (99/116) randomized, only nine women approached (6%) declined to participate. A further 9% (14/149) who were consented antenatally were not eligible at onset of labor and 7% (10/149) of women approached in the birth suite but did not meet the inclusion criteria. Compliance with partograph completion was 65% (action) versus 84% (dystocia line). Conclusions for Practice Participant recruitment to a larger randomized controlled trial comparing new labour management guidelines to standard care is feasible. Effective strategies to improve partograph completion compliance would be required to maintain trial fidelity.

Castor oil for induction of labor in post-date pregnancies: A randomized controlled trial.

BACKGROUND: Castor oil is a substance used for labor induction in an inpatient setting. However, its efficacy as an agent for the induction of labor, for post-date pregnancies in an outpatient setup is unknown. OBJECTIVE: Efficacy of castor oil as an agent for the induction of labor, for post-date pregnancies in outpatient settings. METHODS: Eighty-one women with a low-risk post-date singleton pregnancy with a Bishop score≤7, without effective uterine contractions were randomized to the intervention, 60ml of castor oil, or the control, 60ml of sun-flower oil. The primary outcome was proportion of women entering the active phase of labor 24, 36, 48h after ingestion. Secondary outcomes included meconium stained amniotic fluid, abnormal fetal heart rate tracing, cesarean section rate, instrumental deliveries, birth weight, 5min Apgar score, chorioamnionitis, hypertensive complications, retained placenta, and post-partum hemorrhage. FINDINGS: Intervention and control groups included 38 and 43 women, respectively. No differences in baseline characteristics, except for age were noted. The observed interaction between castor oil and parity was significant (pinteraction=0.02). Multiparous women in the intervention group exhibited a significant beneficial effect on entering active labor within 24, 36 and 48h after castor oil consumption compared with the placebo (Hazard Ratio=2.93, p=0.048; Hazard Ratio=3.29, p=0.026; Hazard Ratio=2.78, p=0.042 respectively). This effect was not noted among primiparous women. No differences in rate of obstetric complications or adverse neonatal outcomes were noted. CONCLUSION: Castor oil is effective for labor induction, in post-date multiparous women in outpatient settings.

Castor oil as a natural alternative to labor induction: A retrospective descriptive study.

AIM: To describe birthing outcomes among women who consumed castor oil cocktail as part of a freestanding birth center labor induction protocol. METHODS: De-identified data from birth logs and electronic medical records were entered into SPSS Statistics 22.0 for analysis for all women who received the castor oil cocktail (n=323) to induce labor between January 2008 and May 2015 at a birth center in the United States. Descriptive statistics were analyzed for trends in safety and birthing outcomes. RESULTS: Of the women who utilized the castor oil cocktail to stimulate labor, 293 (90.7%) birthed vaginally at the birth center or hospital. The incidence of maternal adverse effects (e.g., nausea, vomiting, extreme diarrhea) was less than 7%, and adverse effects of any kind were reported in less than 15% of births. An independent sample t-test revealed that parous women were more likely to birth vaginally at the birth center after using the castor oil cocktail than their nulliparous counterparts (p<.010), while gestational age (p=.26), woman's age (p=.23), and body mass index (p=.28) were not significantly associated. CONCLUSIONS: Nearly 91% of women in the study who consumed the castor oil cocktail to induce labor were able to give birth vaginally with little to no maternal or fetal complications. Findings indicate further research is needed to compare the safety and effectiveness of natural labor induction methodologies, including castor oil, to commonly used labor induction techniques in a prospective study or clinical trial.

Timing of hospital admission in labour: latent versus active phase, mode of birth and intrapartum interventions. A correlational study.

BACKGROUND: Hospitalization of women in latent labour often leads to a cascade of unnecessary intrapartum interventions, to avoid potential disadvantages the recommendation should be to stay at home to improve women's experience and perinatal outcomes. AIM: The primary aim of this study was to investigate the association between hospital admission diagnosis (latent vs active phase) and mode of birth. The secondary aim was to explore the relationship between hospital admission diagnosis, intrapartum intervention rates and maternal/neonatal outcomes. METHODS: A correlational study was conducted in a large Italian maternity hospital. Data from January 2013 to December 2014 were collected from the hospital electronic records. 1.446 records of low risk women were selected. These were dichotomized into two groups based on admission diagnosis: 'latent phase' or 'active phase' of labour. FINDINGS: 52.7% of women were admitted in active labour and 47.3% in the latent phase. Women in the latent phase group were more likely to experience a caesarean section or an instrumental birth, artificial rupture of membranes, oxytocin augmentation and epidural analgesia. Admission in the latent phase was associated with higher intrapartum interventions, which were statistically correlated to the mode of birth. CONCLUSIONS: Women admitted in the latent phase were more likely to experience intrapartum interventions, which increase the probability of caesarean section. Maternity services should be organized around women and families needs, providing early labour support, to enable women to feel reassured facilitating their admission in labour to avoid the cascade of intrapartum interventions which increases the risk of caesarean section.

Pregnant women and health professional's perceptions of complementary alternative medicine, and participation in a randomised controlled trial of acupressure for labour onset.

UNLABELLED: Feasibility randomised controlled trials of complementary medicine are important to evaluate acceptability and practicality. This study examined participants' and health professionals' perceptions of CAM and participation in a feasibility RCT of acupressure for labour onset. METHODS: A qualitative study incorporated within an RCT. Data were collected from postnatal women via questionnaires and health professionals via focus groups. RESULTS: Four themes emerged from the women's views: "Using CAM to start labour", "Feeling empowered through action", "Desiring randomisation to acupressure group", and "Welcoming the opportunity to assist in research". Five themes emerged from the health professionals' views: "Personal awareness and attitudes towards CAM"; "Supporting and empowering women"; "Complements the wellness model of pregnancy and childbirth"; "Need for evidenced based practice"; and "Randomisation 'doing it on the sly'". CONCLUSIONS: Themes from the groups were similar. The study protocol will be refined with a placebo group to improve equipoise with a powered RCT planned.

Being in a safe and thus secure place, the core of early labour: A secondary analysis in a Swedish context.

BACKGROUND: Early labour is the very first phase of the labour process and is considered to be a period of time when no professional attendance is needed. However there is a high frequency of women who seek care at the delivery wards during this phase. When a woman is admitted to the delivery ward, one role for midwives is to determine whether the woman is in established labour or not. If the woman is assessed as being in early labour she will probably then be advised to return home. This recommendation is made due to past research that found that the longer a woman is in hospital the higher the risk for complications for her and her child. Women have described how this situation leaves them in a vulnerable situation where their preferences are not always met and where they are not always included in the decision-making process. AIM: The aim of this study was to generate a theory based on where a woman chooses to be during the early labour process and to increase our understanding about how experiences can differ from place to place. METHODS: The method was a secondary analysis with grounded theory. The data used in the analysis was from two qualitative interview studies and 37 transcripts. CONCLUSION: The findings revealed a substantive theory that women needed to be in a safe and thus secure place during early labour. This theory also describes the interplay between how women ascribed their meaning of childbirth as either a natural live event or a medical one, how this influenced where they wanted to be during early labour, and how that chosen place influenced their experiences of labour and birth.

A feasibility randomised controlled trial of acupressure to assist spontaneous labour for primigravid women experiencing a post-date pregnancy.

OBJECTIVE: this Australian feasibility study aimed to determine; the willingness of women experiencing a post-date pregnancy to participate in a randomised controlled trial (RCT) of acupressure and compliance with the study protocol. The study also aimed to determine the effect size of the primary outcome in order to calculate a sample size for a future appropriately powered RCT. DESIGN: a two-arm randomised controlled trial. Staff providing clinical care were blinded to group allocation unless the participant disclosed study participation. SETTING: maternity services at two outer metropolitan public hospitals in New South Wales, Australia PARTICIPANTS: sixty seven healthy primigravid women experiencing a singleton cephalic pregnancy at 40 weeks±2 days gestation were assessed as eligible to participate and were provided with study information. INTERVENTION: both groups received standard clinical care, with the intervention group also receiving verbal and written instructions on the self-administration of three acupoints (Spleen 6, Large Intestine 4, and Gall Bladder 21) to be used until spontaneous or induced labour began. MEASUREMENTS: assessment of feasibility included determining recruitment rate and acceptability of an RCT for a CAM modality, and acupressure treatment compliance, via participant surveys. The primary clinical outcome was spontaneous onset of labour. FINDINGS: from the 67 women eligible during the timeframe for the study, 44 women (65.6%) agreed to participate and were randomised. There was no statistically significant difference in rate of spontaneous onset of labour (50% acupressure vs 41% control). Twenty nine participant surveys were returned (65.9%). In the intervention group there was a high compliance with the acupressure protocol (83%) and the use of the three acupoints (94%). CONCLUSIONS AND IMPLICATIONS FOR PRACTICE: this feasibility study revealed that pregnant women are interested in the use of CAM, and acupressure in particular, for the initiation of labour. Most women found it acceptable to be randomised to receive the intervention. While the 9% difference in the primary outcome was not statistically significant it is the best estimate of the treatment effect for calculating a sample size of 994 for a future RCT with 80% power, alpha 0.05.

Pilot Study of Physiologic Partograph Use Among Low-Risk, Nulliparous Women With Spontaneous Labor Onset.

INTRODUCTION: Neal and Lowe developed a physiologic partograph to give clinicians an evidence-based, uniform approach to assessing active labor progress and diagnosing dystocia in high-resource settings. The aim of this pilot study was to examine the feasibility of implementing the Neal and Lowe partograph for in-hospital labor assessment. METHODS: A descriptive study of low-risk, nulliparous women with spontaneous labor onset was performed at an academic medical center. Eight certified nurse-midwives from a single practice used the Neal and Lowe partograph for the assessment of labor progress. Descriptive statistics were used to summarize characteristics, interventions, and outcomes for women with partograph-assessed labors. Labors assessed by nurse-midwives (n = 83) or obstetricians (n = 75) using their usual assessment strategies were also described for the year prior to partograph introduction to contextualize partograph-assessed labor findings. Inferential statistical tests were not performed. RESULTS: Thirty-one of 34 (91.2%) partographs were used correctly. Seventy-one percent (n = 22) of these women progressed to complete dilatation within expected physiologic time frames while the remaining women (n = 9) experienced labor dystocia. Similar proportions of women in the partograph and usual labor assessment groups received oxytocin during labor. The cesarean rate was lower in the partograph group than in the usual care groups. No cesareans were performed for dystocia in active labor for women whose labors were assessed via partograph. DISCUSSION: Implementation of the Neal and Lowe partograph for in-hospital labor assessment is feasible. Incorrect plotting and/or interpretation of the partograph may be further minimized by providing clinicians opportunities for ongoing partograph training after implementation or through partograph software development. The Neal and Lowe partograph may assist clinicians in safely and significantly decreasing primary cesarean births performed for active labor dystocia in high-resource settings. Larger scale, hypothesis-testing studies of partograph implementation are now warranted.

Herbal therapies in pregnancy: what works?

PURPOSE OF REVIEW: The aim of this article is two-fold: to report the prevalence of herbal products used by pregnant women and to evaluate the evidence of efficacy and safety of the most popular remedies. RECENT FINDINGS: Of the 671 articles identified, 15 randomized controlled trials (RCTs) and 16 non-RCTs were eligible. Ginger was the most investigated remedy and it was consistently reported to ameliorate nausea and vomiting in pregnancy. Although raspberry, blue cohosh, castor oil, and evening primrose oil are believed to facilitate labor in traditional medicine, very few scientific data support such indication. Moreover, they have been associated with severe adverse events. Data on the safety of Hypericum perforatum in pregnancy or lactation are reassuring, whereas efficacy was demonstrated only in nonpregnant individuals. There is still insufficient evidence regarding the efficacy and safety of Echinacea, garlic, and cranberry in pregnancy. SUMMARY: Epidemiological studies reported a wide range of use of herbal remedies in pregnancy. Too few studies have been devoted to the safety and efficacy of singular herbs. With the exception of ginger, there are no consistent data to support the use of any other herbal supplement during pregnancy. Severe adverse events have been reported using blue cohosh and evening primrose oil.

Dutch women in midwife-led care at the onset of labour: which pain relief do they prefer and what do they use?

BACKGROUND: Pain experienced during labour is more extreme than many other types of physical pain. Many pregnant women are concerned about labour pain and about how they can deal with this pain effectively.The aim of this study was to examine the associations among low risk pregnant women's characteristics and their preferred use and actual use of pain medication during labour. METHODS: Our study is part of the DELIVER study: a dynamic prospective multi-centre cohort study. The data for this study were collected between September 2009 and March 2011, from women at 20 midwifery practices throughout the Netherlands. Inclusion criteria for women were: singleton pregnancies, in midwife-led care at the onset of labour and speaking Dutch, English, Turkish or Arabic. Our study sample consisted of 1511 women in primary care who completed both questionnaire two (from 34 weeks of pregnancy up to birth) and questionnaire three (around six week post partum). These questionnaires were presented either online or on paper. RESULTS: Fifteen hundred and eleven women participated. Prenatally, 15.9% of women preferred some method of medicinal pain relief. During labour 15.2% of the total sample used medicinal pain relief and 25.3% of the women who indicated a preference to use medicinal pain relief during pregnancy, used pain medication. Non-Dutch ethnic background and planned hospital birth were associated with indicating a preference for medicinal pain relief during pregnancy. Primiparous and planned hospital birth were associated with actual use of the preferred method of medicinal pain relief during labour. Furthermore, we found that 85.5% of women who indicated a preference not to use pain medication prenatally, did not use any medication. CONCLUSIONS: Only a small minority of women had a preference for intrapartum pain medication prenatally. Most women did not receive medicinal pain relief during labour, even if they had indicated a preference for it.Care providers should discuss the unpredictability of the labour process and the fact that actual use of pain medication often does not match with women's preference prenatally.

Influence of timing of admission in labour and management of labour on method of birth: results from a randomised controlled trial of caseload midwifery (COSMOS trial).

OBJECTIVE: to explore the relationship between the degree to which labour is established on admission to hospital and method of birth. BACKGROUND: a recent randomised controlled trial found fewer caesarean sections (CS) in women allocated to caseload midwifery (19.4%) compared with standard care (24.9%). There is interest in exploring what specific aspects of the care might have resulted in this reduction. SETTING: a large tertiary-level maternity service in Melbourne, Australia. PARTICIPANTS: English-speaking women with no previous caesarean section at low risk of complications in pregnancy were recruited to a randomised controlled trial. Trial participants whose management did not include a planned caesarean and who were admitted to hospital in spontaneous labour were included in this secondary analysis of trial data (n=1532). METHODS: this secondary analysis included women admitted to hospital in spontaneous labour who were randomised to caseload midwifery compared with those randomised to standard care with regard to timing of admission in labour, augmentation of labour and use of epidural analgesia. In a further analysis randomised groups were pooled to examine predictors of caesarean section for first births only using multiple logistic regression. RESULTS: nulliparous women randomised to standard care were more likely to have labour augmented than those having caseload care (54.2% and 45.5% respectively, p=0.008), but were no more likely to use epidural analgesia. They were admitted earlier in labour, spending 1.1 hours longer than those in the caseload arm in hospital before the birth (p=0.003). Parous women allocated to standard care were more likely than those in the caseload arm to use epidural analgesia (10.0% and 5.3% respectively, p=0.047), but were no more likely to have labour augmented. They were also admitted earlier in labour, with a median cervical dilatation of 4 cm compared with 5 cm in the caseload arm (p=0.012). Pooling the two randomised groups of nulliparous women, and after adjusting for randomised group, maternal age and maternal body mass index, early admission to hospital was strongly associated with caesarean section. Admission before the cervix was 5 cm dilated increased the odds 2.4-fold (95%CI 1.4, 4.0; p=0.001). Augmentation of labour and use of epidural analgesia were each strongly associated with caesarean section (adjusted odds ratios 3.10 (95%CI 2.1, 4.5) and 5.77 (95%CI 4.0, 8.4) respectively. CONCLUSION: these findings that women allocated to caseload care were admitted to hospital later in labour, and that earlier admission was strongly associated with birth by caesarean section, suggest that remaining at home somewhat longer in labour may be one of the mechanisms by which caseload care was effective in reducing caesarean section in the COSMOS trial.
