Labor patterns of spontaneous first-stage labor in Chinese women with normal neonatal outcomes.

BACKGROUND: Friedman's standards, developed almost 50 years ago, may no longer align with the needs of today's obstetric population and current pregnancy management practices. This study aims to analyze contemporary labor patterns and estimate labor duration in China, focusing on first-stage labor data from Chinese parturients with a spontaneous onset of labor. METHODS: This retrospective observational study utilized data from electronic medical records of a tertiary hospital in Changsha, Hunan. Out of a total of 2,689 parturients, exclusions were made for multiple gestations, preterm, post-term, or stillbirth, cesarean delivery, non-vertex presentation, and neonatal intensive care unit admission. Average labor curves were constructed by parity using repeated-measure analysis, and labor duration was estimated through interval-censored regression, stratified by cervical dilation at admission. We performed an analysis to assess the impact of oxytocin augmentation and amniotomy on labor progression and conducted a sensitivity analysis using women with complicated outcomes. RESULTS: Nulliparous women take over 180 minutes for cervical dilation from 3 to 4 cm, and the duration from 5 to 6 cm exceeds 145 minutes. Multiparous women experience shorter labor durations than nulliparous. Labor acceleration is observed after 5 cm in nulliparous, but no distinct inflection point is evident in the average labor curve. In the second stage of labor, the 95th percentile for nulliparous, with and without epidural analgesia, is 142 minutes and 127 minutes, respectively. CONCLUSIONS: These findings provide valuable insights for the reassessment of labor and delivery processes in contemporary obstetric populations, including current Chinese obstetric practice.

Maternal excessive weight gain as a potential risk factor for prolonged labor in Japanese pregnant women: The Japan Environment and Children's Study.

AIM: This study aimed to determine whether excessive maternal weight gain during pregnancy was associated with a higher risk of prolonged labor. METHODS: We analyzed the data regarding maternal weight gain during pregnancy for the participants of Japan Environment and Children's Study (JECS), which is an ongoing nationwide prospective birth cohort study in Japan. After excluding participants with multiple pregnancies, with deliveries before 37 or beyond 42 weeks of gestation, or who had undergone cesarean section, 71,154 (nulliparous, n = 28,442) Japanese women were included. Prolonged labor was defined by a cutoff ranking at the 95th percentile and consequently defined as labor duration exceeding 12.7 h in multiparous women and exceeding 23.2 h in nulliparous women. These classifications were made according to labor curves established by the Japanese Society of Obstetrics and Gynecology Perinatal Committee developed in June 2021. Considering that no studies have conducted an investigation based on this new guideline, we analyzed the association between excessive maternal weight gain during pregnancy and prolonged labor by parity. RESULTS: The overall incidence of prolonged labor was 10.2% (2,907/28,442) in nulliparous women and 6.1% (2,597/42,712) in multiparous women. Multivariable analysis indicated that excessive maternal weight gain was significantly associated with prolonged labor in nulliparous (adjusted odds ratio, 1.21; 95% confidence interval, 1.10-1.32) and multiparous women (adjusted odds ratio, 1.15; 95% confidence interval, 1.05-1.27). Kaplan-Meier survival analysis showed that as labor progressed, the percentage of women who had not yet delivered was higher among those with excessive maternal weight gain than among those with normal maternal weight gain in both the nulliparous (median labor duration 12.9 h vs 12.2 h, p<0.001) and multiparous (median labor duration 6.2 h vs 5.8 h, p<0.001) groups. CONCLUSION: Excessive maternal weight gain was significantly associated with prolonged labor in Japanese women.

Case Report of Hyponatremic Seizures in a Term Neonate Attributed to Excessive Maternal Coconut Water Ingestion During Labor.

We report the case of a term neonate who was somnolent at birth with ventilatory distress and experienced 2 seizures shortly after delivery. Laboratory tests revealed the neonate had a serum sodium of 113 mmol/L. The seizures stopped after treatment with midazolam, and the sodium was corrected slowly with 3% hypertonic saline without further sequelae. The severe neonatal hyponatremia and seizures were attributed to maternal consumption of excessive amounts of coconut water during labor. This case demonstrates the importance of careful consideration of both fluid volume and fluid electrolyte composition during labor to prevent adverse maternal and neonatal outcomes.

Effects of different anesthesia methods on labor process and postpartum serum estrogen and progesterone levels in primiparas with painless labor.

OBJECTIVE: To look into the effects of different anesthesia methods on the labor process and the expression of serum estrogen and progesterone in primiparas with painless labor. METHODS: 60 primiparas receiving painless labor were selected as the research objects, and they were divided into either a Spinal & Continuous epidural anesthesia group (n = 30) or a continuous epidural anesthesia group (n = 30), anesthesia is administered using the corresponding anesthesia method. The authors compared serum estrogen and progesterone, inflammatory index expression, pain degree and neonatal health status in different periods. RESULTS: At T2 and T3, serum P, LH, FSH and E2 levels in the Spinal & Continuous epidural anesthesia group were signally lower than those in the Spinal & Continuous epidural anesthesia group (p < 0.05). Spinal & Continuous epidural anesthesia group harbored faster onset and longer duration of sensory block and motor block than the Continuous epidural anesthesia group (p < 0.05). SAS and SDS scores of the Spinal & Continuous epidural anesthesia group were clearly lower than those of the Continuous epidural anesthesia group (p < 0.05). VAS score and serum TNF-α, IL-6 levels of pregnant women in the Spinal & Continuous epidural anesthesia group were memorably lower than those in the Continuous epidural anesthesia group at T2 and T3 (p < 0.05). The total incidence of postoperative complications in the Spinal & Continuous epidural anesthesia group was distinctively lower than that in the Continuous epidural anesthesia group (p < 0.05). CONCLUSION: Spinal anesthesia combined with continuous epidural anesthesia has a better anesthesia effect in the painless labor of primiparas, which can effectually ameliorate the labor process and the expression of serum estrogen and progesterone.

Programmed Intermittent Epidural Bolus Reduces Workloads in Labor Analgesia: A Single Center's Experience.

Background and Objectives: Labor epidural analgesia can be maintained through programmed intermittent epidural bolus (PIEB), continuous epidural infusion (CEI), or patient-controlled epidural analgesia (PCEA). Our department changed from CEI+PCEA to PIEB+PCEA as the maintenance method. The higher hourly dose setting in the current regimen brought to our concern that side effects would increase with proportional staff workloads. This study aimed to investigate the validity of our proposal that PIEB+PCEA may function as a feasible tool in reducing the amount of work in the obstetrics anesthesia units. Materials and methods: This 2-year retrospective review included parturients with vaginal deliveries under epidural analgesia. We compared the staff burden before and after the switch from CEI (6 mL/h, PCEA 6 mL lockout 15 min, group A) to PIEB (8 mL/h, PCEA 8 mL lockout 10 min, group B). The primary outcome was the difference of proportion of parturients requiring unscheduled visits between groups. Side effects and labor and neonatal outcomes were compared. Results: Of the 694 parturients analyzed, the proportion of those requiring unscheduled visits were significantly reduced in group B (20.8% vs. 27.7%, chi-square test, p = 0.033). The multivariate logistic regression showed that PIEB was associated with fewer unscheduled visits than CEI (OR = 0.53, 95% CI [0.36-0.80], p < 0.01). Group B exhibited a significantly lower incidence of asymmetric blockade, as well as motor blockade. In nulliparous subjects, obstetric anal sphincter injury occurred less frequently when PIEB+PCEA was used. Significantly more multiparous women experienced vacuum extraction delivery in group B than in group A, and they had a longer second stage of labor. Conclusions: The PIEB+PCEA protocol in our study reduced workloads in labor epidural analgesia as compared to CEI+PCEA, despite that a higher dose of analgesics was administered. Future studies are warranted to investigate the effect of manipulating the PIEB settings on the labor outcomes.

Effect of dural puncture epidural block technique on fetal heart rate variability during labor analgesia.

PURPOSE: To explore the effect of dural puncture epidural (DPE) block technique on fetal heart rate variability (HRV) during labor analgesia. METHODS: Sixty full-term primiparas who were in our hospital from April 2021 to October 2021 were selected and randomized into epidural analgesia (CEA) and dural puncture epidural analgesia (DPEA) groups (n = 30). After a successful epidural puncture, routine epidural catheter (EC) was performed in CEA group, and spinal anesthesia needle (as an EC) was used to puncture the dura mater to subarachnoid space in DPE group. Anesthetics were injected through EC. The time when the temperature sensation plane reached T10 (W1) and visual analog pain score (VAS), baseline heart rate score, amplitude variation score, cycle variation score, acceleration score, deceleration score, and total score of the first contraction after W1 were recorded. Apgar scores at 1 min, 5 min, and 10 min of neonates after delivery were recorded. RESULTS: The onset time of anesthesia in CEA group was significantly longer than that in DPEA group (p < .05). However, there are no significant differences in W1, VAS, baseline heart rate score, amplitude variation score, cycle variation score, acceleration score, deceleration score, and total score of the first contraction after W1 between the two groups (p > .05). Moreover, the Apgar scores at 1 min, 5 min and 10 min of neonates after delivery were not notably different between the two groups (p > .05). CONCLUSION: Compared with CEA, DPE block technique in labor analgesia relieves maternal pain without adverse effects on fetal HRV and newborns.

The application of DPE, CSEA, and EA in labor analgesia for nulliparous women and their impact on maternal and infant safety.

This work compared the effects of dural puncture epidural (DPE), combined spinal epidural analgesia (CSEA) and epidural analgesia (EA) on labor analgesia for primiparae and their impacts on maternal and infant safety. A total of 204 primiparae in need of labor analgesia for vaginal delivery were allocated to DPE, CSEA and EA groups. At 10 min, 30 min and 1 h after analgesia, the DPE and CSEA groups showed lower VAS scores and quicker onset of action than EA group. There was no significant difference in the duration of analgesia and labor and fetal decelerations among the 3 groups. At 1 min and 5 min after childbirth, the neonatal Apgar scores showed no significant difference between the 3 groups. The Bromage scores of DPE and EA groups were lower than those of CSEA group. The incidence of pruritus, hypotension, and postpartum headache in DPE and EA groups were lower than those in CSEA group. To sum up, the efficacy of DPE in labor analgesia for primiparae is similar to that of CSEA, with no obvious effect on labor stage and neonatal Apgar score, no additional complications and less LLMB, pruritus, hypotension and postpartum headache.

Labor Support during the Early Months of the COVID-19 Pandemic in the United States.

PURPOSE: To describe the experiences of registered nurses and certified nurse midwives who provided labor support and care in the early months of the COVID-19 pandemic. STUDY DESIGN AND METHODS: A descriptive, qualitative approach was used to explore nurses' and midwives' perceptions via in-depth interviews. Data were analyzed via thematic analysis. RESULTS: Thirteen nurses, four of whom were also midwives, participated in semi-structured interviews. All provided care during the first 9 months of the pandemic and represented seven states across the United States. The analysis revealed an overarching theme, A New World but still a Celebration. This overarching theme encompasses participants' accounts of trying to provide the same support, presence, and celebration while dealing with constant policy changes, the impact of limited family presence in labor, and their own fears and risks. Four sub-themes were identified: The Impact of Nursing during COVID-19; Challenges, Changes, and Consequences; Unexpected Benefits; and The Cost. CLINICAL IMPLICATIONS: The first year of the COVID-19 pandemic saw unprecedented challenges for nurses. Practice changes due to these changing policies had negative and positive effects. Negative practices affected family support, decreased interprofessional collaboration, and caused shorter hospital stays for new mothers. Some positive aspects of practice changes included additional time for mother-newborn bonding due to restrictive visitation policies, increased initiation of breastfeeding, and focused patient education. Nurses across the United States are still coping with practice changes from the pandemic. Our study highlights the need to support nurses in adapting care in the midst of practice changes.

Epidural analgesia in labour: separating fact from fiction for autism and neurodevelopment.

Having epidural analgesia in labour has been associated with a later diagnosis of autism spectrum disorder in the offspring, resulting in concerns about childhood wellbeing. Neurodevelopmental changes are inconsistently reported in the literature, creating challenges in the interpretation of these findings. Here we explore the limitations of the current evidence base, and why findings differ between studies, concluding that the current body of evidence does not support a causal association between use of epidural analgesia in labour and autism spectrum disorder.

Patterns of oxytocin use for induction and augmentation of labour among healthcare providers in Nigeria.

BACKGROUND: The practice of intrapartum use of oxytocin for induction and augmentation of labour is increasing worldwide with documented wide variations in clinical use, especially dose administrations. There is also evidence of intrapartum use by unauthorized cadre of staff. AIM: This study assessed the patterns - frequency of intrapartum use of oxytocin, the doses and routes of administration for induction and augmentation of labour, and identified the predictors of oxytocin use for induction and augmentation of labour by healthcare providers in Nigeria. METHODS: This was a cross-sectional study conducted among healthcare providers - doctors, nurses/midwives and community health workers (CHWs) in public and private healthcare facilities across the country's six geopolitical zones. A multistage sampling technique was used to select 6,299 eligible healthcare providers who use oxytocin for pregnant women during labour and delivery. A self-administered questionnaire was used to collect relevant data and analysed using STATA 17 statistical software. Summary and inferential statistics were done and further analyses using multivariable regression models were performed to ascertain independent predictor variables of correct patterns of intrapartum oxytocin usage. The p-value was set at < 0.05. RESULTS: Of the 6299 respondents who participated in the study, 1179 (18.7%), 3362 (53.4%), and 1758 (27.9%) were doctors, nurses/midwives and CHWs, respectively. Among the respondents, 4200 (66.7%) use oxytocin for augmentation of labour while 3314 (52.6%) use it for induction of labour. Of the 1758 CHWs, 37.8% and 49% use oxytocin for induction and augmentation of labour, respectively. About 10% of the respondents who use oxytocin for the induction or augmentation of labour incorrectly use the intramuscular route of administration and about 8% incorrectly use intravenous push. Being a doctor, and a healthcare provider from government health facilities were independent positive predictors of the administration of correct dose oxytocin for induction and augmentation of labour. The CHWs were most likely to use the wrong route and dose administration of oxytocin for the induction and augmentation of labour. CONCLUSION: Our study unveiled a concerning clinical practice of intrapartum oxytocin use by healthcare providers in Nigeria - prevalence of intrapartum use of oxytocin, inappropriate routes of administration for induction and augmentation of labour, varied and inappropriately high start dose of administration including unauthorized and high intrapartum use of oxytocin among CHWs.

Management of Spontaneous Vaginal Delivery.

Pregnancy dating is determined by the patient's last menstrual period or an ultrasound measurement. A full-term pregnancy is considered 37 weeks' gestation or more. Spontaneous labor begins when regular painful uterine contractions result in a cervical change. Active labor begins at 6 cm dilation and is marked by more predictable, accelerated cervical change. In the absence of pregnancy complications, intermittent fetal auscultation may be considered as an alternative to continuous electronic fetal monitoring, which is associated with a high false-positive rate. Intravenous antibiotic prophylaxis is indicated in patients with group B streptococcus colonization or those at high risk to prevent newborn early-onset group B streptococcus. The likelihood of vaginal delivery is increased by providing continuous nonmedical support during labor, encouraging mobility, and using a peanut ball with epidural analgesia. Neuraxial analgesia is more effective for pain control than systemic opioids and is associated with fewer adverse effects. Delayed pushing during the second stage of labor has risks but does not affect the mode of delivery. Routine oropharyngeal suctioning of the newborn is not recommended, even with meconium-stained amniotic fluid. Delayed cord clamping reduces newborn anemia. Prevention of postpartum hemorrhage in patients at risk includes prophylactic uterotonic administration and controlled cord traction. Perineal lacerations that alter anatomy or are not hemostatic should be repaired. (Am Fam Physician. 2024;109(6):525-532.

Codesign and refinement of an optimised antenatal education session to better inform women and prepare them for labour and birth.

OBJECTIVE: Our objective was to codesign, implement, evaluate acceptability and refine an optimised antenatal education session to improve birth preparedness. DESIGN: There were four distinct phases: codesign (focus groups and codesign workshops with parents and staff); implementation of intervention; evaluation (interviews, questionnaires, structured feedback forms) and systematic refinement. SETTING: The study was set in a single maternity unit with approximately 5500 births annually. PARTICIPANTS: Postnatal and antenatal women/birthing people and birth partners were invited to participate in the intervention, and midwives were invited to deliver it. Both groups participated in feedback. OUTCOME MEASURES: We report on whether the optimised session is deliverable, acceptable, meets the needs of women/birthing people and partners, and explain how the intervention was refined with input from parents, clinicians and researchers. RESULTS: The codesign was undertaken by 35 women, partners and clinicians. Five midwives were trained and delivered 19 antenatal education (ACE) sessions to 142 women and 94 partners. 121 women and 33 birth partners completed the feedback questionnaire. Women/birthing people (79%) and birth partners (82%) felt more prepared after the class with most participants finding the content very helpful or helpful. Women/birthing people perceived classes were more useful and engaging than their partners. Interviews with 21 parents, a midwife focus group and a structured feedback form resulted in 38 recommended changes: 22 by parents, 5 by midwives and 11 by both. Suggested changes have been incorporated in the training resources to achieve an optimised intervention. CONCLUSIONS: Engaging stakeholders (women and staff) in codesigning an evidence-informed curriculum resulted in an antenatal class designed to improve preparedness for birth, including assisted birth, that is acceptable to women and their birthing partners, and has been refined to address feedback and is deliverable within National Health Service resource constraints. A nationally mandated antenatal education curriculum is needed to ensure parents receive high-quality antenatal education that targets birth preparedness.

'Giving birth on a beach': Women's experiences of using virtual reality in labour.

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

Influence of non-pharmacological methods on duration of labor: a systematic review.

The article aims to verify the influence of MNFs on the duration of the birth process. A systematic review was carried out in the MEDLINE, Web of Science and LILACS databases, through a combination of terms that cover the topic addressed, from 1996 to 2021/April. The Excel spreadsheet was used to collect data to extract information regarding each selected article, in turn, data analysis included the evaluation and classification of quality, reliability and risk of bias, thus, the following tools were used: Cochrane RoB 2, Checklist and Newcastle-Ottawa Scale. Warm bath, walking, exercises with a birthing ball, breathing techniques, supine position, acupuncture, acupressure and water birth reduced labor time. While spontaneous pushing, massage and immersion baths prolonged labor. Non-pharmacological methods capable of reducing the duration of labor were hot/warm shower, walking, birth ball exercises, breathing techniques, maternal mobility, dorsal position, acupuncture, acupressure and water birth, as well. associated applied techniques such as hot/warm bath, ball exercises and lumbosacral massage, as well as immersion bath, ball exercises, aromatherapy, vertical postures and maternal mobility with alternating vertical postures, shortened the birth time.

Quality of hospital labour and delivery care: A multilevel analysis in Southern Nations and Nationalities People's Region of Ethiopia.

BACKGROUND: Ethiopia has one of the highest maternal mortality ratios in Africa. Few have examined the quality of labour and delivery (L&D) care in the country. This study evaluated the quality of routine L&D care and identified patient-level and hospital-level factors associated with the quality of care in a subset of government hospitals. MATERIALS AND METHODS: This was a facility-based, cross-sectional study using direct non-participant observation carried out in 2016. All mothers who received routine L&D care services at government hospitals (n = 20) in one of the populous regions of Ethiopia, Southern Nations Nationalities and People's Region (SNNPR), were included. Mixed effects multilevel linear regression modeling was employed in two stages using hospital as a random effect, with quality of L&D care as the outcome and selected patient and hospital characteristics as independent variables. Patient characteristics included woman's age, number of previous births, number of skilled attendants involved in care process, and presence of any danger sign in current pregnancy. Hospital characteristics included teaching hospital status, mean number of attended births in the previous year, number of fulltime skilled attendants in the L&D ward, whether the hospital had offered refresher training on L&D care in the previous 12 months, and the extent to which the hospital met the 2014 Ethiopian Ministry of Health standards regarding to resources available for providing quality of L&D care (measured on a 0-100% scale). These standards pertain to availability of human resource by category and training status, availability of essential drugs, supplies and equipment in L&D ward, availability of laboratory services and safe blood, and availability of essential guidelines for key L&D care processes. RESULTS: On average, the hospitals met two-thirds of the standards for L&D care quality, with substantial variation between hospitals (standard deviation 10.9 percentage points). While the highest performing hospital met 91.3% of standards, the lowest performing hospital met only 35.8% of the standards. Hospitals had the highest adherence to standards in the domain of immediate and essential newborn care practices (86.8%), followed by the domain of care during the second and third stages of labour (77.9%). Hospitals scored substantially lower in the domains of active management of third stage of labour (AMTSL) (42.2%), interpersonal communication (47.2%), and initial assessment of the woman in labour (59.6%). We found the quality of L&D care score was significantly higher for women who had a history of any danger sign (ß = 5.66; p-value = 0.001) and for women who were cared for at a teaching hospital (ß = 12.10; p-value = 0.005). Additionally, hospitals with lower volume and more resources available for L&D care (P-values < 0.01) had higher L&D quality scores. CONCLUSIONS: Overall, the quality of L&D care provided to labouring mothers at government hospitals in SNNPR was limited. Lack of adherence to standards in the areas of the critical tasks of initial assessment, AMTSL, interpersonal communication during L&D, and respect for women's preferences are especially concerning. Without greater attention to the quality of L&D care, regardless of how accessible hospital L&D care becomes, maternal and neonatal mortality rates are unlikely to decrease substantially.

Protocol of Birth in Brazil II: National Research on Abortion, Labor and Childbirth. / Protocolo do Nascer no Brasil II: Pesquisa Nacional sobre Aborto, Parto e Nascimento.

Brazil has made advances in obstetric care in public and private hospitals; however, weaknesses in this system still require attention. The Brazilian Ministry of Health, aware of this need, funded the second version of the Birth in Brazil survey. This study aimed to evaluate: prenatal, labor and birth, postpartum, and abortion care, comparing the results with those of Birth in Brazil I; and analyze the main determinants of perinatal morbidity and mortality; evaluate the care structure and processes of obstetrics and neonatology services in maternity hospitals; analyze the knowledge, practices, and attitudes of health professionals who provide birth and abortion care; and identify the main barriers and facilitators related to care of this nature in Brazil. With a national scope and a 2-stage probability sample: 1-hospitals and 2-women, stratified into 59 strata, 465 hospitals were selected with a total planned sample of around 24,255 women - 2,205 for abortion reasons and 22,050 for labor reasons. Data collection was conducted using six electronic instruments during hospital admission for labor or abortion, with two follow-up waves, at two and four months. In order to expand the number of cases of severe maternal morbidity, maternal and perinatal mortality, three case control studies were incorporated into Birth in Brazil II. The fieldwork began in November 2021 and is scheduled to end in 2023. It will allow a comparison between current labor and birth care results and those obtained in the first study and will evaluate the advances achieved in 10 years.

Com o passar do tempo, o Brasil vem apresentando avanços na assistência obstétrica em hospitais públicos e privados; no entanto, ainda existem pontos frágeis que necessitam de atenção. O Ministério da Saúde, ciente dessa necessidade, financiou a segunda versão da pesquisa Nascer no Brasil. Os objetivos gerais são: avaliar a assistência pré-natal, ao parto e nascimento, ao puerpério e ao aborto, comparando com os resultados do Nascer no Brasil I, e analisar os principais determinantes da morbimortalidade perinatal; avaliar a estrutura e processos assistenciais dos serviços de obstetrícia e neonatologia das maternidades; analisar os conhecimentos, atitudes e práticas de profissionais de saúde que prestam assistência ao parto e ao aborto; e identificar as principais barreiras e facilitadores para essa assistência no país. Com escopo nacional e amostra probabilística em dois estágios (1-hospitais e 2-mulheres), dividida em 59 estratos, foram selecionados 465 hospitais com total planejado de, aproximadamente, 24.255 mulheres, 2.205 por motivo de aborto e 22.050 por motivo de parto. A coleta de dados, realizada por meio de seis instrumentos eletrônicos, ocorre durante a internação hospitalar para o parto ou aborto, com duas ondas de seguimento, aos dois e quatro meses. Com o intuito de expandir o número de casos de morbidade materna grave, mortalidade materna e perinatal, três estudos caso controle foram incorporados ao Nascer no Brasil II. O trabalho de campo foi iniciado em novembro de 2021 com término previsto para 2023. Os resultados permitirão comparar a atenção atual ao parto e ao nascimento com a retratada no primeiro inquérito e, com isso, avaliar os avanços alcançados no decorrer desses 10 anos.

Aunque Brasil ha presentado avances en la atención obstétrica en hospitales públicos y privados, todavía hay puntos débiles que necesitan atención. El Ministerio de Salud, consciente de esta necesidad, financió la segunda versión de la encuesta Nacer en Brasil. Los objetivos generales son: evaluar la atención prenatal, el parto y el nacimiento, el puerperio y el aborto, comparando con los resultados del Nacer en Brasil I, y analizar los principales determinantes de la morbimortalidad perinatal; evaluar la estructura y los procesos de atención de los servicios de obstetricia y neonatología en las maternidades; analizar los conocimientos, prácticas y actitudes de los profesionales de la salud que brindan atención para el parto y el aborto; e identificar las principales barreras y facilitadores para esta atención en el país. Tiene un alcance nacional y muestra probabilística en dos etapas (1-hospitales y 2-mujeres), la cual se dividió en 59 estratos; y se seleccionaron 465 hospitales con un total planificado de aproximadamente 24.255 mujeres, de las cuales 2.205 tuvieron procedimientos por aborto y 22.050 por parto. Para la recolección de datos se aplicó seis instrumentos electrónicos, que se realizó durante la hospitalización por parto o aborto, con dos rondas de seguimiento, a los dos y cuatro meses. Con el fin de ampliar el número de casos de morbilidad materna grave, mortalidad materna y perinatal, se incorporaron tres estudios de casos y controles en Nacer en Brasil II. El trabajo de campo comenzó en noviembre de 2021 y finalizará en 2023. Los resultados nos permitirán evaluar la atención al parto y al nacimiento actual con lo que se retrató en la primera encuesta, de esta manera se podrá evaluar los avances alcanzados a lo largo de estos 10 años.

Tending to the machine: The impact of intrapartum fetal surveillance on women in Australia.

Qualitative research about women and birthing people's experiences of fetal monitoring during labour and birth is scant. Labour and birth is often impacted by wearable or invasive monitoring devices, however, most published research about fetal monitoring is focused on the wellbeing of the fetus. This manuscript is derived from a larger mixed methods study, 'WOmen's Experiences of Monitoring Baby (The WOMB Study)', aiming to increase understanding of the experiences of women and birthing people in Australia, of being monitored; and about the information they received about fetal monitoring devices during pregnancy. We constructed a national cross-sectional survey that was distributed via social media in May and June, 2022. Responses were received from 861 participants. As far as we are aware, this is the first survey of the experiences of women and birthing people of intrapartum fetal monitoring conducted in Australia. This paper comprises the analysis of the free text survey responses, using qualitative and inductive content analysis. Two categories were constructed, Tending to the machine, which explores participants' perceptions of the way in which clinicians interacted with fetal monitoring technologies; and Impressions of the machine, which explores the direct impact of fetal monitoring devices upon the labour and birth experience of women and birthing people. The findings suggest that some clinicians need to reflect upon the information they provide to women and birthing people about monitoring. For example, freedom of movement is an important aspect of supporting the physiology of labour and managing pain. If freedom of movement is important, the physical restriction created by a wired cardiotocograph is inappropriate. Many participants noticed that clinicians focused their attention primarily on the technology. Prioritising the individual needs of the woman or birthing person is key to providing high quality woman-centred intrapartum care. Women should be provided with adequate information regarding the risks and benefits of different forms of fetal monitoring including how the form of monitoring might impact her labour experience.

Changes of serum cortisol during pregnancy and labor initiation: an onsite cross-sectional study.

Background: Increased maternal cortisol secretion has been observed during pregnancy and labor. However, due to the limitations in diagnostic methods, the dynamic change of cortisol during the short period between threatened labor and labor is unknown. In this study, we aim to evaluate the changes in serum cortisol during late pregnancy and full-term labor initiation, verifying if cortisol could serve as a biomarker for the diagnosis of labor initiation from threatened labor. Methods: This cross-sectional onsite study involved 564 participants of 6 different gestational stages (C: Control; T1: Trimester 1; T3: Trimester 3; E: expectant; TL: threatened labor; L: labor), all patients in the E, TL, and L groups were at full term. The serum cortisol concentration was quantified with a point-of-care test (POCT), and the gestation, age, parity, and BMI of participants were documented. Morning serum cortisol was collected between 8:00 and 10:00 a.m., except for the TL and L group women who were tested upon arrival or during latent labor. With cortisol levels or all five variables, L was distinguished from TL using machine learning algorithms. Results: Significant elevation of cortisol concentration was observed between T1 and T3, or TL and L group (P< 0.001). Women belonging to the E and TL group showed similar gestation week and cortisol levels. Diagnosis of labor initiation using cortisol levels (cutoff = 21.46 µg/dL) yielded sensitivity, specificity, and AUC of 86.50%, 88.60%, and 0.934. With additional variables, a higher specificity (89.29%) was achieved. The diagnostic accuracy of all methods ranged from 85.93% to 87.90%. Conclusion: Serum cortisol could serve as a potential biomarker for diagnosis of L form TL. The rapid onsite detection of serum cortisol with POCT could facilitate medical decision-making for admission and special treatments, either as an additional parameter or when other technical platforms are not available.

An online survey of women's views of respectful and disrespectful pregnancy and early labour care in the Czech Republic.

OBJECTIVE: To ascertain and explore the views of women and their partners, giving birth in the Czech Republic, of the level of respectful or disrespectful care provided during pregnancy and early labour. DESIGN: Ethical approval was granted for a descriptive, online anonymous survey of 65 questions, with quantitative and qualitative responses. SETTING: The Czech Republic.The survey was completed by 8,767 women and 69 partners in 2018. MEASUREMENTS AND FINDINGS: Descriptive statistics and thematic analysis were used to present results. The majority of women were aged 26-35 years. Most had birthed in one of 93 hospitals, with 1.5% home births. Almost 40% never had an abdominal examination.in pregnancy. Quantitative data analysis revealed that less than half were given information on place of birth, or how to keep labour normal or non-interventionist. Almost 60% did not get information on positions for birth. Most (68%) commenced labour naturally, 25% had labour induced, 40% of them before term, and 7% had an elective caesarean section; 55% stated they had not been given any choice in the decision. Over half of those who had a membrane sweep said permission had not been sought. Half (54%) only had 'checking' visits from the midwife in labour. KEY CONCLUSIONS: Findings reveal a lack of information-giving, discussion and shared decision-making from healthcare professionals during pregnancy and early labour. Some practices were non-evidenced-based, and interventions were sometimes made without consent. IMPLICATIONS FOR PRACTICE: The examples of disrespectful care described in this study caused women distress during childbirth, which may result in an increased fear of childbirth or an increase in free-birthing.

Role of mitochondrial DNA level in epidural-related maternal fever: a single-centre, observational, pilot study.

INTRODUCTION: Epidural analgesia has been associated with intrapartum maternal fever development. Epidural-related maternal fever (ERMF) is believed to be based on a non-infectious inflammatory reaction. Circulating cell-free mitochondrial deoxyribonucleic acid (mtDNA) is one of the possible triggers of sterile inflammatory processes; however, a connection has not been investigated so far. Therefore, this study aimed to investigate cell-free mtDNA alterations in women in labour with ERMF in comparison with non-febrile women. MATERIAL AND METHODS: A total of 60 women in labour were assessed for maternal temperature every 4 h and blood samples were obtained at the beginning and after delivery. Depending on the analgesia and the development of fever (axillary temperature ≥ 37.5 °C), the women were allocated either to the group of no epidural analgesia (n = 17), to epidural analgesia no fever (n = 34) or to ERMF (n = 9). Circulating cell-free mtDNA was analysed in the maternal plasma for the primary outcome whereas secondary outcomes include the evaluation of inflammatory cytokine release, as well as placental inflammatory signs. RESULTS: Of the women with epidural analgesia, 20% (n = 9) developed ERMF and demonstrated a decrease of circulating mtDNA levels during labour (p = 0.04), but a trend towards higher free nuclear DNA. Furthermore, women with maternal pyrexia showed a 1.5 fold increased level of Interleukin-6 during labour. A correlation was found between premature rupture of membranes and ERMF. CONCLUSIONS: The pilot trial revealed an evident obstetric anaesthesia phenomenon of maternal fever due to epidural analgesia in 20% of women in labour, demonstrating counterregulated free mtDNA and nDNA. Further work is urgently required to understand the connections between the ERMF occurrence and circulating cell-free mtDNA as a potential source of sterile inflammation.
