Breastfeeding outcomes in late preterm infants: A multi-centre prospective cohort study.

To describe (1) infant feeding practices during initial hospitalisation and up to 6 months corrected age (CA) in infants born late preterm with mothers intending to breastfeed, (2) the impact of early feeding practices on hospital length of stay and (3) maternal and infant factors associated with duration of breastfeeding. We conducted a prospective cohort study of infants born at 34+0 to 36+6 weeks gestational age during 2018-2020. Families were followed up until the infant reached 6 months of age (corrected for prematurity). Feeding practices during the birth hospitalisation, length of initial hospital stay, and the prevalence of exclusive or any breastfeeding at 6 weeks, 3 months, and 6 months CA were examined. Associations between maternal and infant characteristics and breastfeeding at 6 weeks, 3 months and 6 months CA were assessed using multivariable logistic regression models. 270 infants were enrolled, of these, 30% were multiple births. Overall, 78% of infants received only breastmilk as their first feed, and 83% received formula during the hospitalisation. Seventy-four per cent of infants were exclusively breastfed at discharge, 41% at 6 weeks CA, 35% at 3 months CA, and 29% at 6 months CA. The corresponding combined exclusive and partial breastfeeding rates (any breastfeeding) were 72%, 64%, and 53% of babies at 6 weeks CA, 3 months CA, and 6 months CA, respectively. The mean duration of hospitalisation was 2.9 days longer (95% confidence interval (CI) 0.31, 5.43 days) in infants who received any formula compared with those receiving only breastmilk (adjusted for GA, maternal age, multiple birth, site, and neonatal intensive care unit admission). In multivariable models, receipt of formula as the first milk feed was associated with a reduction in exclusive breastfeeding at 6 weeks CA (odds ratio = 0.22; 95% CI 0.09 to 0.53) and intention to breastfeed >6 months with an increase (odds ratio = 4.98; 95% CI 2.39 to 10.40). Intention to breastfeed >6 months remained an important predictor of exclusive breastfeeding at 3 and 6 months CA. Our study demonstrates that long-term exclusive breastfeeding rates were low in a cohort of women intending to provide breastmilk to their late preterm infants, with approximately half providing any breastmilk at 6 months CA. Formula as the first milk feed and intention to breastfeed >6 months were significant predictors of breastfeeding duration. Improving breastfeeding outcomes may require strategies to support early lactation and a better understanding of the ongoing support needs of this population.

Pregnancy outcomes in breech presentation at term: a comparison between 2 third level birth center protocols

Medical literature supports planned cesarean delivery for breech presentation at term because of observed reductions in neonatal morbidity and mortality compared with vaginal breech delivery. This study aimed to compare perinatal outcomes of singleton pregnancies with breech presentation at term according to the different delivery protocols of 2 teaching hospitals, where vaginal breech delivery (protocol 1) or cesarean delivery (protocol 2) is routinely offered, respectively. A retrospective matched cohort study was conducted between January 2015 and May 2021. A total of 1079 women were eligible for analysis. After matching for possible confounding factors, the final analysis was performed on 257 patients in each group. The primary outcomes were a composite of adverse obstetrical outcomes and a composite of neonatal adverse outcomes. Overall, 1079 women were eligible for analysis. After matching for possible confounding factors, the final analysis was performed on 257 patients in each group. The composite of adverse obstetrical outcomes was similar in the 2 groups (24.1% vs 24.5%; P=1.000); however, the composite of neonatal adverse outcomes was significantly higher for protocol 1 (17.9% vs 1.2%; P<.001). No neonatal death or birth trauma was reported in either group. The rates of neonatal intensive care unit admission (4.3% vs 0.4%; P=.004), respiratory distress at birth (17.5% vs 1.2%; P<.001), and Apgar scores of <7 after 5 minutes (5.8% vs 0.4%; P<.001) were significantly higher for protocol 1. Short-term, nonsevere adverse neonatal outcomes were significantly increased in the protocol 1 group. These must be balanced against the possible negative effects of cesarean delivery on long-term infant and maternal health.

Complementary and Integrative Health Practices in a Brazilian Freestanding Birth Center: A Cross-Sectional Study.

The study aimed to analyze the use of complementary and integrative health practices (CIHPs) during labor and birth in a freestanding birth center. A total of 28 different CIHPs were applied with or used by laboring women. The most adopted CIHPs were mind-body practices (99.9%) and natural products (35.5%), mostly used by primiparous women (P <.05). Adopting CIHPs can increase care quality, increase positive experiences during childbirth, and promote evidence-based choices.

The experience of obstetric nursing students in an innovative maternal care programme in Chiapas, Mexico: a qualitative study

In Mexico, over the last decade, more non-physician medical professionals have been participating in birth care according to recent federal regulations. So far, very few sites have been able to implement birth care models where midwives and obstetric nurses participate. We describe the experience of a group of intern obstetric nurses participating in a model that provides respectful birth care to rural populations, managed by an international NGO in partnership with the Ministry of Health of Chiapas, Mexico. We conducted a case study including individual interviews and focus group discussions with obstetric nurse interns participating in the Compañeros En Salud programme over four years from 2016 to 2019. We applied targeted content analysis to the qualitative data. There were 28 participants from 4 groups of interns. Informants expressed their opinions in four areas: (a) training as a LEO, (b) training experience at CES, (c) LEO role in health care delivery; and (d) LEOs' perspectives about respectful maternity care. Interns identified gaps in their training including a higher load of theoretical content vs practical experience, as well as little supervision of clinical care in public hospitals. Their adaptation to the health services model has increased over time, and recent classes acknowledge the difficulties that earlier ones had to confront, including the challenging interactions with hospital staff. Interns have incorporated the value of respectful birth care and their role to protect this right in rural populations. Findings could be useful to call for the expansion of the model in public birth centres.

Episiotomy for Medical Indications during Vaginal Birth-Retrospective Analysis of Risk Factors Determining the Performance of This Procedure.

The WHO (World Health Organization) recommends that the percentage of perineal incisions should not exceed 10%, indicating that this is a good goal to achieve, despite the fact that it is still a frequently used medical intervention in Poland. The risk factors for perineal incision that have been analyzed so far in the literature allow, among others, to limit the frequency of performing this procedure. Are they still valid? Have there been new risk factors that we should take into account? We have conducted this study to find the risk factors for performing perineal incision that would reduce the frequency of this procedure. The aim of the study was to check whether the risk factors that were analyzed in the literature are still valid, to find new risk factors for perineal incisions and to compare them among Polish women. This was a single-center retrospective case-control study. The electronic patient records of Saint Sophia’s Hospital in Warsaw, Poland, a tertiary hospital was used to create an anonymous retrospective database of all deliveries from 2015 to 2020. The study included the analysis of two groups, the study group of patients who had had an episiotomy, and the control group-patients without an episiotomy in cases where an episiotomy was indicated. A logistic regression model was developed to assess the risk factors for perineal laceration. Independent risk factors for episiotomy in labor include oxytocin use in the second stage of labor (OR (Odds Ratio) = 6.00; 95% CI (Confidence Interval): 4.76–7.58), the supply of oxytocin in the first and the second stage of labor (OR = 3.18; 95% CI: 2.90–3.49), oxytocin use in the first stage of labor (OR = 2.72; 95% CI: 2.52–3.51), state after cesarean section (OR = 2.97; 95% CI: 2.52–3.51), epidural anesthesia use (OR = 1.77; 95% CI: 1.62–1.93), male gender (OR = 1.10; 95% CI: 1.02–1.19), and prolonged second stage of labor (OR = 1.01; 95% CI: 1.01–1.01). A protective factor against the use of an episiotomy was delivery in the Birth Centre (OR = 0.43; 95% CI: 0.37–0.51) and mulitpara (OR = 0.31; 95% CI: 0.27–0.35). To reduce the frequency of an episiotomy, it is necessary consider the risk factors of performing this procedure in everyday practice, e.g., limiting the use of oxytocin or promoting alternative places of delivery.

A hybrid type I, multi-center randomized controlled trial to study the implementation of a method for Sustained cord circulation And VEntilation (the SAVE-method) of late preterm and term neonates: a study protocol

BackgroundAn intact umbilical cord allows the physiological transfusion of blood from the placenta to the neonate, which reduces infant iron deficiency and is associated with improved development during early childhood. The implementation of delayed cord clamping practice varies depending on mode of delivery, as well as gestational age and neonatal compromise. Emerging evidence shows that infants requiring resuscitation would benefit if respiratory support were provided with the umbilical cord intact. Common barriers to providing intact cord resuscitation is the availability of neonatal resuscitation equipment close to the mother, organizational readiness for change as well as attitudes and beliefs about placental transfusion within the multidisciplinary team. Hence, clinical evaluations of cord clamping practice should include implementation outcomes in order to develop strategies for optimal cord management practice.MethodsThe Sustained cord circulation And Ventilation (SAVE) study is a hybrid type I randomized controlled study combining the evaluation of clinical outcomes with implementation and health service outcomes. In phase I of the study, a method for providing in-bed intact cord resuscitation was developed, in phase II of the study the intervention was adapted to be used in multiple settings. In phase III of the study, a full-scale multicenter study will be initiated with concurrent evaluation of clinical, implementation and health service outcomes. Clinical data on neonatal outcomes will be recorded at the labor and neonatal units. Implementation outcomes will be collected from electronic surveys sent to parents as well as staff and managers within the birth and neonatal units. Descriptive and comparative statistics and regression modelling will be used for analysis. Quantitative data will be supplemented by qualitative methods using a thematic analysis with an inductive approach.DiscussionThe SAVE study enables the safe development and evaluation of a method for intact cord resuscitation in a multicenter trial. The study identifies barriers and facilitators for intact cord resuscitation. The knowledge provided from the study will be of benefit for the development of cord clamping practice in different challenging clinical settings and provide evidence for development of clinical guidelines regarding optimal cord clamping.Trial registrationClinicaltrials.gov, NCT04070560.

The effect on the birth experience of women and partners of giving birth in a “birth environment room”: A secondary analysis of a randomised controlled trial

ObjectiveTo evaluate women and partners' experience of birth in a "birth environment room" compared to a standard birth room. DesignA single centre parallel randomised controlled trial. Women and partners were enrolled during a 3-year period (May 2015 to March 2018). SettingThe Department of Obstetrics and Gynaecology at Herning Hospital, Denmark. Participants and interventionA total of 680 Danish speaking nulliparous women, more than 18 years old, with a singleton pregnancy in cephalic presentation, and a spontaneous onset of labour, and their partners were randomly assigned to give birth in a “birth environment room” (n = 340) or in a standard birth room (n = 340) on arrival at the birth unit. Measurements and findingsOutcomes were the overall birth experience and overall satisfaction with care, measured on a Likert scale, obtained in the postpartum questionnaire sent to the women 6 weeks after birth and to their partners 1/2 weeks after birth. Other outcomes were “staff support for partner”, “undisturbed contact with new-born”, “feeling of being listened to”, “level of information”, “attention to psychological needs”, “suggestions for pain-relief”, “participation in decision-making”, “midwife present when wanted”, “support from midwife”, “birth wishes were met”, “loss of internal control” (only women), “loss of external control”, “support from partner” (partners: “being supportive for partner”), “importance of physical environment for birth” and “importance of physical environment for staff´s ability to involve the women” (only women). All outcomes were prespecified. We applied Mann Whitney U test for comparing the two groups. Data were collected from 326 women and 236 partners in the intervention group and from 315 women and 209 partners in the control group. The intention-to-treat analysis revealed no difference in the overall experience of birth for women or partners (p 0.81 and p 0.17, respectively). Partners in the intervention group reported more overall satisfaction with care compared to partners in the control group (p 0.048). In the intervention group, fewer women and partners responded they had not had the opportunity for undisturbed contact with their new-born in the first hours after birth (RR 0.19 (95% CI 0.04-0.87) and OR 0.00 CI (0.00–0.83), respectively). Otherwise, there were no differences between groups. The thematic analysis revealed that many women and partners felt they were not able to benefit from the features in “the birth environment room” in the most intense hours of birth. Key conclusion and implications for practice"The birth environment room" did not improve the overall experience of birth for women and partners. Partners in the intervention group were overall more satisfied with care. These findings are of importance in the developing of physical birth environments that support the mental/emotional process of labour.

A true choice of place of birth? Swiss women's access to birth hospitals and birth centers.

While the place of birth plays a crucial role for women's birth experiences, the interest in out-of-hospital births has increased during the Covid-19 pandemic. Related to this, various international policies recommend enabling women to choose where to give birth. We aimed to analyze Swiss women's choice between birth hospitals and birth centers. Employing spatial accessibility analysis, we incorporated four data types: highly disaggregated population data, administrative data, street network data, addresses of birth hospitals and birth centers. 99.8% of Swiss women of childbearing age were included in the analysis (N = 1.896.669). We modelled car travel times from a woman's residence to the nearest birth hospital and birth center. If both birth settings were available within 30 minutes, a woman was considered to have a true choice. Only 58.2% of women had a true choice. This proportion varied considerably across Swiss federal states. The main barrier to a true choice was limited accessibility of birth centers. Median travel time to birth hospitals was 9.8 (M = 12.5), to birth centers 23.9 minutes (M = 28.5). Swiss women are insufficiently empowered to exercise their reproductive autonomy as their choice of place of birth is significantly limited by geographical constraints. It is an ethical and medical imperative to provide women with a true choice. We provide high-resolution insights into the accessibility of birth settings and strong arguments to (re-)examine the need for further birth centers (and birth hospitals) in specific geographical areas. Policy-makers are obligated to improve the accessibility of birth centers to advance women's autonomy and enhance maternal health outcomes after childbirth. The Covid-19 pandemic offers an opportunity to shift policy.

Adoption of Consensus Guidelines for Safe Prevention of the Primary Cesarean Delivery by Freestanding Birth Centers.

Slow or arrested progress in labor is the most frequent (64%) indication for nonemergent transfer of laboring people from freestanding birth centers to the hospital. After the 2014 publication of the Consensus Statement on Safe Prevention of Primary Cesarean Delivery (Consensus Statement), many freestanding birth centers changed their clinical practice guidelines to allow more time for active labor in the birth center prior to hospital transfer. The result of these changes has not been evaluated in birth centers. Evaluation of adoption of guidelines based on the Consensus Statement in hospitals has shown inconsistent results. Birth centers were contacted to determine whether they changed clinical practice guidelines in response to the Consensus Statement. A before-after analysis compared outcomes for the 2 calendar years before and the 2 calendar years after adoption of new guidelines with a retrospective analysis of deidentified client-level data collected in the American Association of Birth Centers Perinatal Data Registry. A third of responding birth centers (11 of 33) changed their clinical practice guidelines, mostly redefining the onset of active labor as beginning at 6 cm cervical dilatation and allowing 4 hours of arrest of dilatation in active labor before transfer to the hospital. These changes were associated with fewer diagnoses of prolonged first stage of labor (13.8% vs 8.0%, P &lt; .01) but not with fewer intrapartum transfers (14.0% vs 14.7%, P = .55) or cesarean births (5.0 vs 4.1%, P = .26.) DISCUSSION: We found no evidence that making these practice changes was associated with better outcomes. Two hours of a lack of documented cervical change in active labor is likely long enough to diagnose arrested progress in labor. Research on proportion of morbidity and mortality associated with prolonged labor could inform practice guidelines for transfers.

Outcomes of Cannabis Use During Pregnancy Within the American Association of Birth Centers Perinatal Data Registry 2007-2020: Opportunities Within Midwifery-Led Care.

Healthcare providers require data on associations between perinatal cannabis use and birth outcomes. This observational secondary analysis come from the largest perinatal data registry in the United States related to the midwifery-led birth center model care (American Association of Birth Centers Perinatal Data Registry; N = 19 286). Births are planned across all birth settings (home, birth center, hospital); care is provided by midwives and physicians. Population data show that both early and persistent self-reports of cannabis use were associated with higher rates of preterm birth, low-birth-weight, lower 1-minute Apgar score, gestational weight gain, and postpartum hemorrhage. Once controlled for medical and social risk factors using logistic regression, differences for childbearing people disappeared except that the persistent use group was less likely to experience "no intrapartum complications" (adjusted odds ratio [aOR] = 0.49; 95% confidence interval [CI], 0.32-0.76; P < .01), more likely to experience an indeterminate fetal heart rate in labor (aOR = 3.218; 95% CI, 2.23-4.65; P < .05), chorioamnionitis (aOR = 2.8; 95% CI, 1.58-5.0; P < .01), low-birth-weight (aOR = 1.8; 95% CI, 1.08-3.05; P < .01), and neonatal intensive care unit (NICU) admission (aOR = 2.4; 95% CI, 1.30-4.69; P < .05). Well-controlled data demonstrate that self-reports of persistent cannabis use through the third trimester are associated with an increased risk of low-birth-weight and NICU admission.

A Descriptive Study of Maternal Choices for Labor Pain Relief.

In a setting with a wider than usual variety of available labor pain relief methods, a prospective, descriptive study was conducted of labor pain relief methods desired by low-risk women prenatally, during labor, and at delivery. Of all women registering for care between 2017 and 2020, a total of 2562 women were screened for low-risk status and then offered study participation, if eligible. Of 1185 eligible women, 512 remained at low risk until admission in labor and completed the study. Pain relief methods chosen were compared with the type of labor, type of delivery, and between delivery sites. Hydrotherapy and a "none/unmedicated" labor were favored by a majority of subjects, regardless of ultimate method used. Multiple labor pain relief methods were used by 54.5% of subjects. Epidural analgesia most often occurred with augmented labor. Hydrotherapy was used more by those with spontaneous labors, water birth deliveries, and birth center births. Effectiveness of all pain relief measures was rated above average. Differences between planned hospital and planned birth center births were clear on most variables. Results can be used by childbirth educators, health professionals, and administrators to respect and improve the individualization of care and satisfaction of laboring women.

Prenatal diagnosis of congenital soft tissue hemangioma of the fetal back

Congenital hemangiomas are benign vascular lesions found in fetuses. Congenital hemangiomas develop in utero, have a maximum size at birth (in the absence of subsequent bleeding). Such hemangiomas occur in 1–2% of newborns. Prenatal ultrasound diagnostics and magnetic resonance imaging occupy an important place in the diagnosis, which determines the tactics of management and treatment of the patient. To present a clinical case of prenatal diagnosis of congenital soft tissue hemangioma of the fetal back. A pregnant woman A., 34, was sent to St. Petersburg State Public Health Institution «Diagnostic Center» (medical and genetic) with suspected spina bifida of the fetus after screening in late pregnancy period in one of the Birth Centres. Performed prenatal ultrasound (US) pregnant A. for a period of 34 weeks. According to ultrasound data in the region of the spine at the level of XI–XII thoracic vertebrae, an ovoid formation with clear even contours, a fairly homogeneous solid structure, with a clear capsule, 33×24×30 mm in size (volume 12.4 cm3) is determined subcutaneously. The diagnosis made: hemangioma of the soft tissues of the fetal back. Prenatal screening plays a key role in the diagnosis of congenital hemangiomas. Timely detection of this benign formation affects the tactics of management and delivery.

Technical Report: Breastfeeding and the Use of Human Milk.

Breastfeeding and human milk are the normative standards for infant feeding and nutrition. The short- and long-term medical and neurodevelopmental advantages of breastfeeding make breastfeeding or the provision of human milk a public health imperative. The American Academy of Pediatrics (AAP) recommends exclusive breastfeeding for approximately 6 months after birth. Furthermore, the AAP supports continued breastfeeding, along with appropriate complementary foods introduced at about 6 months, as long as mutually desired by mother and child for 2 years or beyond. These recommendations are consistent with those of the World Health Organization (WHO). Medical contraindications to breastfeeding are rare. The AAP recommends that birth hospitals or centers implement maternity care practices shown to improve breastfeeding initiation, duration, and exclusivity. The Centers for Disease Control and Prevention and The Joint Commission monitor breastfeeding practices in United States hospitals. Pediatricians play a critical role in hospitals, their practices, and communities as advocates of breastfeeding and, thus, need to be trained about the benefits of breastfeeding for mothers and children and in managing breastfeeding. Efforts to improve breastfeeding rates must acknowledge existing disparities and the impact of racism in promoting equity in breastfeeding education, support, and services.

How to Foster Effective Midwife-Obstetrician Collaboration on Labor and Birth Units: Qualitative Analysis of Experiences of Clinicians in the United States.

Effective collaboration between midwives and obstetricians on labor and birth units in hospitals has been shown to improve birth outcomes and quality of care. Guidelines for collaborative care in the United States exist; however, studies describing the actual lived experiences of midwives and obstetricians in collaborative practice are lacking. The goal of this study was to explore the experiences and perspectives of midwives and obstetricians working in collaborative practices on labor and birth units across the United States and to identify strategies that foster effective collaboration between them. We performed qualitative analyses of open-ended comments obtained in an instrument validation survey assessing collaboration between midwives and obstetricians on labor and birth in the United States. Certified nurse-midwives, certified midwives, attending general obstetricians, maternal-fetal medicine attending physicians, and fellows across the United States were included in this study, herein called midwives and obstetricians. The final sample in the original validation survey included 232 midwives and 471 obstetricians (n = 703). Of these, 79 midwives and 132 obstetricians (n = 211) provided narrative comments on their perspectives and experiences with collaborative practice on labor and birth units in the United States. The narrative comments were analyzed using inductive techniques derived from grounded theory. Four themes around how to foster effective collaboration were identified: (1) developing trust and respect, (2) promoting effective communication, (3) individual variability and need for clear guidelines, and (4) balancing autonomy. The midwives and obstetricians shared lived experiences that they perceived affected their work satisfaction and clinical outcomes in collaborative practices. These findings hold potential to inform clinicians and health care leaders on ways to foster effective collaboration between midwives and obstetricians on labor and birth units. This in turn can improve quality of care for birthing persons, perinatal outcomes and clinician job satisfaction.

Association between SARS-CoV-2 Infection and Adverse Perinatal Outcomes in a Large Health Maintenance Organization.

This study aimed to examine whether severe acute respiratory syndrome-coronavirus-2 (SARS-CoV-2) infection during pregnancy is associated with increased odds of perinatal complications and viral transmission to the infant. A retrospective cohort study of women who delivered at Kaiser Permanente Southern California hospitals (April 6, 2020-February 28, 2021) was performed using data extracted from electronic health records (EHRs). During this time polymerize chain reaction (PCR)-based tests for SARS-CoV-2 was universally offered to all pregnant women at labor and delivery admission, as well as earlier in the pregnancy, if they were displaying symptoms consistent with SARS-CoV-2 infection or a possible exposure to the virus. Adjusted odds ratio (aOR) was used to estimate the strength of associations between positive test results and adverse perinatal outcomes. Of 35,123 women with a singleton pregnancy, 2,203 (6%) tested positive for SARS-CoV-2 infection with 596 (27%) testing positive during the first or second trimester and 1,607 (73%) during the third trimester. Women testing positive were younger than those who tested negative (29.7 [5.4] vs. 31.1 [5.3] years; mean [standard deviation (SD)]; p < .001). The SARS-CoV-2 infection tended to increase the odds of an abnormal fetal heart rate pattern (aOR: 1.10; 95% confidence interval [CI]: 1.00, 1.21; p = 0.058), spontaneous preterm birth (aOR: 1.28; 95% CI: 1.03, 1.58; p = 0.024), congenital anomalies (aOR: 1.69; 95% CI: 1.15, 2.50; p = 0.008), and maternal intensive care unit admission at delivery (aOR: 7.44; 95% CI: 4.06, 13.62; p < 0.001) but not preeclampsia/eclampsia (aOR: 1.14; 95% CI: 0.98, 1.33; p = 0.080). Eighteen (0.8%) neonates of mothers who tested positive also had a positive SARS-CoV-2 test after 24 hours of birth, but all were asymptomatic during the neonatal period. These findings suggest that prenatal SARS-CoV-2 infection increases the odds of some adverse perinatal outcomes. The likelihood of vertical transmission from the mother to the fetus was low (0.3%), suggesting that pregnancy complications resulting from SARS-CoV-2 infection pose more risk to the baby than transplacental viral transmission. · SARS-CoV-2 infection is associated with increased odds of adverse perinatal outcomes.. · The odds of specific adverse outcomes were greater when a mother was infected earlier in pregnancy.. · The proportion of vertical transmission from mother to fetus was 0.3%.

Use of external cephalic version for breech presentation at term: A national survey of Norwegian birth units

IntroductionInternational guidelines recommend that external cephalic version (ECV) be offered to all women with single fetuses in breech presentation at term. In Norway, ECV is not offered routinely; the national clinical guidelines advice that birth units capable of offering ECV for breech pregnancies make their own practice decisions. This study was performed to determine the extent to which Norwegian birth units offer ECV to pregnant women with fetuses in breech presentations at term, and to identify factors that might influence the use of ECV. Material and methodsA survey of all 39 obstetric birth units providing ECV in Norway was conducted using a self‐reporting questionnaire about ECV availability, attitudes, clinical procedures, perceived competence, and outcome expectations. ResultsChief obstetricians from all birth units responded. Twenty-six (67%) respondents reported that their units offered ECV for breech presentation at term to a large degree. Thirty-one (80%) respondents reported a large degree of competence in performing ECV. Thirty-three (85%) units followed local ECV procedures. Nineteen (49%) units provided standardized information about the procedure to pregnant women. The respondents had different views about who should be offered ECV, and varying knowledge about ECV outcomes. ConclusionsThe majority of Norwegian birth units offer ECV to pregnant women with fetuses in breech position to a large extent. However, the survey results reveal challenges related to ECV information provision to pregnant women, determination of women’s eligibility for ECV attempts, and familiarity and agreement with the knowledge base regarding ECV.

Fetal station at caesarean section and risk of subsequent preterm birth - A cohort study

ObjectivesAn increased risk of preterm birth (PTB) following a caesarean section (CS) in the second stage of labor has been demonstrated. We aimed to investigate the relationship between the station of the presenting fetal part and the surgical technique at first CS, and the risk of subsequent PTB. Study designThis was a cohort study of 11,850 women in Sweden, delivered by CS in 2001–2007 at any of 23 birth units, with a second delivery in 2001–2009. Clinical information was retrieved from electronic birth records linked to national health registers. The risk of subsequent PTB was analyzed by fetal station, defined as low (at or below the ischial spines) or high (above the ischial spines), and aspects of the surgical technique at index CS. Associations were explored with logistic regression and results are presented as odds ratios (ORs) with 95% confidence intervals (CIs), by type and severity (very early < 32 gestational weeks and moderate preterm 32–36 gestational weeks) of PTB. Multiple logistic regression included adjustments for maternal age, gestational age at first delivery, and inter-delivery interval. ResultsOut of 11,850 women delivered by CS, 1,016 (8.6%) delivered preterm in their subsequent pregnancy. There was an increased likelihood of spontaneous PTB, but not with medically indicated PTB, after an index CS with the fetal presenting part at a low station (aOR 1.61, 95% CI 1.23–2.11). CS performed at a low station was associated with birth < 32 gestational weeks (aOR 1.73, 95% CI 1.05–2.84) and birth at 32–36 gestational weeks (aOR 1.29, 95% CI 1.00–1.65), compared with high fetal station. Thickness of the uterine wall, incision type, and closure of the uterus at index CS did not affect the risk. ConclusionA primary CS at a low station was associated with a subsequent spontaneous PTB, but not medically indicated PTB. Surgical technique at index CS did not alter the risk.

Choosing a Birth Setting: A Shared Decision-Making Approach.

Perinatal outcomes vary widely depending on individual birth settings (birth center, home, and hospital). The purpose of this case study is to explore a patient-centered, shared decision-making approach to achieve an informed, values-based choice about birth settings. Engaging in a shared decision-making approach regarding birth setting options would support people to have the information and ability to judge for themselves how benefits and risks across birth center, home, and hospital settings would best fit with their values and personal health. A patient decision aid about birth setting options could facilitate increased equity regarding access to birth settings that offer improved perinatal health outcomes, helping to reduce perinatal health disparities in the United States.

The duration of spontaneous active and pushing phases of labour among 75,243 US women when intervention is minimal: A prospective, observational cohort study

SummaryBackgroundFriedman's curve, despite acknowledged limitations, has greatly influenced labour management. Interventions to hasten birth are now ubiquitous, challenging the contemporary study of normal labour. Our primary purpose was to characterise normal active labour and pushing durations in a large, contemporary sample experiencing minimal intervention, stratified by parity, age, and body mass index (BMI).MethodsThis is a secondary analysis of the national, validated Midwives Alliance of North America 4·0 (MANA Stats) data registry (n = 75,243), prospectively collected between Jan 1, 2012 and Dec 31, 2018 to describe labour and birth in home and birth center settings where common obstetric interventions [i.e., oxytocin, planned cesarean] are not available. The MANA Stats cohort includes pregnant people who intended birth in these settings and prospectively collects labour and birth processes and outcomes regardless of where birth or postpartum care ultimately occurs. Survival curves were calculated to estimate labour duration percentiles (e.g. 10th, 50th, 90th, and others of interest), by parity and sub-stratified by age and BMI.FindingsCompared to multiparous women (n = 32,882), nulliparous women (n = 15,331) had significantly longer active labour [e.g., median 7.5 vs. 3.3 h; 95th percentile 34.8 vs. 12.0 h] and significantly longer pushing phase [e.g., median 1.1 vs. 0.2 h; 95th percentile 5.5 vs. 1.1 h]. Among nulliparous women, maternal age >35 was associated with longer active first stage of labour and longer pushing phase, and BMI >30 kg/m² was associated with a longer active first stage of labour but a shorter pushing phase. Patterns among multiparous women were different, with those >35 years of age experiencing a slightly more rapid active labour and no difference in pushing duration, and those with BMI >30 kg/m² experiencing a slightly longer active labour but, similarly, no difference in pushing duration.InterpretationNulliparous women had significantly longer active first stage and pushing phase durations than multiparous women, with further variation noted by age and by BMI. Contemporary US women with low-risk pregnancies who intended birth in settings absent common obstetric interventions and in spontaneous labour with a live, vertex, term, singleton, non-anomalous fetus experienced labour durations that were often longer than prior characterizations, particularly among nulliparous women. Results overcome prior and current sampling limitations to refine understanding of normal labour durations and time thresholds signaling ‘labour dystocia’.FundingOHSU Nursing Innovation and OHSU University Shared Resources.
