RESUMO

Cervical assessment on the Bishop scale prior to induction of labor (IOL) is one of the strongest prognostic criteria in relation to the success of the procedure. The commonly used preinduction methods are mainly aimed at reducing the percentage of cesarean sections. Our study has analyzed obstetric results of patients who had unripe cervix (Bishop score <7) before IOL and used preinduction (Foley catheter or misoprostol vaginal insert releasing 7 mcg of misoprostol per hour for 24 hours) with obstetric results of patients in whom, due to favourable cervix, only a low-dose infusion of oxytocin was used. We reviewed the medical records of 1010 single pregnancies in whom IOL was performed. We divided the patients into two groups: group A (where preinduction was used) and group B (Bishop score ≥7 points) where preinduction was not used. Patients in group A were more likely to complete the delivery by caesarean section (OR = 4.58, 95% CI 3.22-6.51), and more likely to have events that were indications for operative delivery: unreassuring fetal heart rate trace (OR = 3.29, 95% CI 2.07-5.23) and arrested labor or failed induction (OR = 3.4, 95% CI 2.06-5.62). The groups did not differ in the percentage of vacuum extraction, postpartum haemorrhage, and meconium stained amniotic fluid. In group B, more infants were born with umbilical cord blood pH <7.1 (1.38% vs. 0%), both groups included no deliveries of newborns with Apgar score ≤3 points, the groups did not differ in terms of the percentage of newborns with Apgar score between 4 and 7 at birth (OR = 0.66, 95% CI 0.29-1.49). The immature cervix and the need to use labor preinduction is a risk factor for caesarean section. The necessity of preinduction does not impair neonatological results.

RESUMO

Background: Episiotomy is the most common obstetric procedure, performed when the clinical circumstances place the patient at a high risk of high-degree laceration. However, episiotomy should be done with judicious indication to lower perineal laceration with fewer complications. Despite its adverse effects, the magnitude of episiotomy is increasing due to different factors. Therefore, this study is aimed at determining the recent magnitude of episiotomy and at identifying associated factors among women who gave delivery in Arba Minch General Hospital, Southern Ethiopia. Methods: An institution-based cross-sectional study was conducted from December 15, 2018, to January 30, 2019. A systematic random sampling technique was used to select study participants. A semistructured questionnaire was used to collect data. This was supplemented with a review of the labor and delivery records. Binary and multivariable logistic regression analyses were performed to identify factors associated with the magnitude of episiotomy. P value ≤ 0.05 was used to determine the level of statistically significant variables. Results: The magnitude of episiotomy was found to be 272 (68.0%) with 95%CI = 64.0-72.5. Women who attended secondary education [AOR = 10.24, 95%CI = 2.81-37.34], women who attended college and above [AOR = 4.61, 95%CI = 1.27-16.71], birth weight ≥ 3000 g [AOR = 4.84, 95%CI = 2.66-8.82], primipara [AOR = 4.13, 95%CI = 2.40-7.12], being housewife occupants [AOR = 3.43, 95%CI = 1.20-9.98], married women [AOR = 2.86, 95%CI = 1.40-5.84], and body mass index < 25 kg/m2 [AOR = 2.85, 95%CI = 1.50-5.44] were independent variables found to have significant association with episiotomy. Conclusion: The magnitude of episiotomy was 68.0% which is higher than the recommended practice by WHO (10%). The study participants' occupational status, marital status, educational status, parity, birth weight, and BMI were significantly associated with the magnitude of episiotomy in the study area. Therefore, to reduce the rate of episiotomy, it is better to have periodic training for birth attendants regarding the indication of episiotomy.

RESUMO

OBJECTIVE: The aim: to study the possible role of psychosocial stressors in the emergence of anomalies of childbirth, as well as to examine their nature using the example of pregnant women who have been forcefully displaced from Donetsk and Luhansk regions of Ukraine. PATIENTS AND METHODS: Materials and methods: 115 internally displaced pregnant women from Donetsk and Luhansk regions, were surveyed. All women underwent a comprehensive neuropsychological examination of their psycho-emotional status via interviews, questioning, and psychological testing (Spielberg-Haning's Situational and Personal Anxiety Scale). The following analysis of the childbirth process' nature was conducted. RESULTS: Results: The prevalence of high level of situational and personal anxiety by the Spielberg-Haning's test were determined in the internally displaced women. This indicates a high level of social anxiety (stress) in these pregnant women. Labours in women in this group can be characterized by 3 main features: rapid (precipitated) labour with high levels of obstetric traumatism (tear of perineum) and labour medicalization (EDA). The characteristics described above are due to such labour activity anomalies as hypertensive uterine dysfunction - the cases when the speed and strength of uterine contractions significantly exceed the normative parameters. The reasons for the high level of pain in labour in displaced women could be objecttive and subjective factors: excessive nociceptor irritation due to cervical-uterine dysfunction and impaired individual perception of pain. CONCLUSION: Conclusions: Chronic psychosocial stress has an impact on labour activity in displaced women. A mandatory standard for managing such pregnancy is psychological counselling and correction of the identified disorders.

RESUMO

As the novel coronavirus disease (COVID-19) escalates globally, and no end in sight, we describe an approach for adapting swiftly to the increasing number of COVID-19 parturients admitted into labor and delivery unit. The adaptability includes physical layout, triaging, quick testing, isolating confirmed parturients, access to designated intensive care units, facilitating emergent cesarean deliveries, and educating health care personnel. It is vital that other healthy parturi-ents and healthcare providers must be protected from COVID-19. It is encouraged that institutions exchange and dis-seminate information to succeed in the global fight against this dreaded pandemic.

RESUMO

Background: This paper reports on part of a larger study, the aim of which was to develop an intervention to collaboratively develop innovative strategies to promote effective collaborative practices among midwives and medical professionals working in intrapartum care unit. Collaborative practice is a critical marker for success in improving quality of maternity care. To date, there has been limited exploration of collaborative practices between midwives and medical professionals working in intrapartum care from the African perspective. Aim: This paper reports findings of the discovery phase of appreciative inquiry (AI) set out to understand the perspectives of midwives and medical professionals on collaborative practices at Queen Elizabeth Central Hospital labour and delivery ward in Malawi. Methods: The study used an exploratory qualitative approach framed in an Appreciative Inquiry theoretical perspective. Appreciative Inquiry consists of four phases :(discovery, dream, design and destiny).The discovery phase consisted of 16 in-depth interviews and 2 focus group discussions among purposively selected midwives (4 nurse midwives, 2 midwifery unit matrons) and medical professionals (2 obstetricians, 4 registrars, 2 intern doctors, 2 clinical officers) working in the labour ward. All interviews and discussions were audiotaped and transcribed verbatim. Data were analysed using thematic analysis. Results: Five dominant themes emerged: collaborative breakdown, benefits of collaboration, the importance of positive and respectful attitude, barriers to effective collaborative practices and strategies to improve collaborative practice. Conclusion/Recommendations: Aligning the perspectives of the members of the two disciplines is significant to effective implementation of collaborative intrapartum care. Participants demonstrated that there is increased parallel working of midwives and doctors at QECH. This is not professionally healthy. Therefore, putting together the viewpoints of the professions to create a mutually agreeable professional framework of collaborative intrapartum practice is significant. Additionally, there is an obvious need to address the professional concerns of both disciplines.

RESUMO

Objective: To evaluate the effect of dual-tube epidural segmental injection of lidocaine analgesia on the delivery outcome and maternal and infant complications of persistent posterior occipital position postpartum or lateral occipital position postpartum patients with protracted active phase. Methods: The full and single-term primiparas (n=216, 37 to 42 weeks gestation, 22 to 35 years) diagnosed as persistent posterior or lateral occipital position during the active period were selected from the Department of Obstetrics of Qingdao Municipal Hospital from January 2015 to October 2019. The subjects were randomly assigned into two groups: double-tube epidural block group (n=108) and single-tube epidural block group (n=108), 1% lidocaine was used for epidural analgesia respectively under ultrasound guidance. Senior midwife or obstetricians implement new partogram, and guide women to perform position management, and push or rotate the fetal head in a timely manner. Observation indicators: general condition, the use of non-pharmacological analgesic measures, analgesia related conditions and pain visual analogue scale (VAS) score, delivery-related indicator, cesarean section indication, anesthesia-related indicator, maternal and child complications. Results: (1) General condition: the age, weight, height, gestational age, the ratio of persistent lateral or posterior occipital position, cephalic score, and neonatal birth weight between the two groups of women were not statistically significant (all P>0.05). (2) The use of non-pharmacological analgesic measures: the women's Lamaze breathing method, Doula delivery companionship, percutaneous electrical stimulation, and other measures between two groups were compared, and there were not significant differences (all P>0.05). (3) Analgesia related conditions and VAS scores of women undergoing vaginal delivery: compared with the single-tube epidural block group (n=40), the second-partum time of the women in the double-tube epidural block group (n=59) was significantly shortened [(124±44) vs (86±33) minutes, P<0.01]; after 30 minutes of analgesia (4.4±0.5 vs 0.9±0.5, P<0.01), during forced labor in the second stage of labor (5.7±0.6 vs 1.3±0.4, P<0.01), the VAS scores of pain were also significantly reduced (P<0.01). (4) Labor-related indicators: compared with the single-tube epidural block group, the natural delivery rate (21.3% vs 49.1%) and the delivery experience satisfaction rate (51.9% vs 98.1%) of women in the double-tube epidural block group were significantly increased (all P<0.01), cesarean section rate (63.0% vs 45.4%), instrument assisted rate (15.7% vs 5.6%) decreased significantly (all P<0.05). (5) Cesarean section indications: compared with the single-tube epidural block group, the cesarean section rate caused by prolonged labor or protracted active phase of women in the double-tube epidural block group was significantly reduced (38.0% vs 22.2%; P<0.05), and the fetal distress, intrauterine infection, and social factors caused by cesarean section between the two groups were compared, while the differences were not statistically significant (all P>0.05).(6) Anesthesia related indexes: the block planes of the maternal upper tube administration in the double-tube epidural block group were mostly T7, T8, T9-L2 and L3,While,the block planes in the single-tube epidural block group were mostly T10, T11-S1, S2, S3, and the modified Bromage score were all 0. (7) Maternal and child complications: compared with the single-tube epidural block group, the postpartum hemorrhage rate (18.5% vs 7.4%), the perineal lateral cut rate (20.4% vs 5.6%), the neonatal asphyxia rate (12.0% vs 3.7%), ICU rate of transferred neonates (13.9% vs 4.6%) in the double-tube epidural block group were significantly reduced (all P<0.05). Soft birth canal injury rate, puerperal disease rate and neonatal birth rate between two groups were compared, and there were not statistically significant differences (all P>0.05). Conclusion: Dual-tube epidural segmental injection of lidocaine analgesia could increase the natural delivery rate of women with posterior occipital or lateral occipital position with active stagnation, reduce the rate of cesarean section and the rate of transvaginal instruments, and reduce the complications of mother and child.

RESUMO

Objective: To analyze the perinatal outcomes of unicornuate uterus pregnancy. Methods: The clinical data of patients with unicornuate uterus pregnancy who delivered between January 2009 and December 2018 in Women's Hospital, School of Medicine, Zhejiang University, were reviewed retrospectively. Live birth was defined as the delivery of a baby after at least 28 weeks gestational age. Ninety-eight patients were diagnosed as unicornuate uterus, while 4 cases of stillbirth and 4 cases of twin pregnancy and 10 cases of incomplete data were excluded, and 80 patients with unicornuate uterus were included in the observation group. By matching the age, gestational age and delivery mode, 160 patients were randomly selected as the control group. The perinatal outcomes such as delivery mode, cesarean section indication sequence, postpartum hemorrhage, vaginal delivery time, newborn birth weight and Apgar score were analyzed retrospectively. Results: In the unicornuate uterus group, there were 10 cases of vaginal delivery and 70 cases of cesarean section, among which the primary indication of premature cesarean section and full-term cesarean section was abnormal fetal position, accounting for 7/18 and 50.0% (26/52), respectively. While in the control group, there were 20 cases of vagianl delivery and 140 cases of cesarean section, among which the main indications of premature cesarean section were placenta previa, intrahepatic cholestasis during pregnancy and scar uterus, accounting for 19.4% (7/36), and the primary indication of full-term cesarean section was abnormal fetal position, accounting for 23.1% (24/104). The postpartum hemorrhage of the vaginal delivery in the unicornuate uterus group and the control group was (319±161) and (261±152) ml, respectively, and the postpartum hemorrhage of the cesarean section delivery was (257±106) and (272±123) ml, respectively. There were no significant differences between the two groups statistically (all P>0.05). The time of the first stage of labor was (502±386) and (465±296) minutes in the unicornuate uterus group and the control group, and the time of the second stage was (74±73) and (47±30) minutes, respectively. There were no significant differences between the two groups statistically (all P>0.05). The neonatal birth weight in the unicornuate uterus group and the control group was (3 018±548) and (3 080±562) g, respectively, and there was no significant difference between the two groups statistically (P=0.42). According to preterm birth and different pre-pregnancy body mass index, the neonatal birth weight of the two groups were compared, and the differences were not statistically significant (all P>0.05). One-minute Apgar score of premature in the unicornuate uterus group and the control group were 10 (9.25-10) and 10 (10-10), 5-minute Apgar score were 10 (10-10) and 10 (10-10), respectively. One-minute Apgar score of full-term in the unicornuate uterus group and the control group were 10 (10-10) and 10 (10-10), 5-minute Apgar score were 10 (10-10) and 10 (10-10), respectively. There were no statistically significant differences between the two groups, respectively (all P>0.05). Conclusions: The patients with unicornuate uterus could give birth vaginally in the absence of other operation indications. The perinatal outcome of women with unicornuate uterus is similar to that of women with non-uterine abnormalities. It is found that the abnormal fetal position with unicornuate uterus is the main reason for cesarean section.

RESUMO

BACKGROUND: Continuous intrapartum fetal monitoring is challenging and its clinical benefits are debated. The project evaluated whether short-term-variation (STV) and other computerised fetal heart rate (FHR) parameters (baseline FHR, long-term-variation, accelerations and decelerations) predicted acidaemia at birth. The aims of the study were to assess the changes in FHR pattern during labour and determine the feasibility of undertaking a definitive trial by reporting the practicalities of using the monitoring device, participant recruitment, data collection and staff training. METHODS: 200 high-risk women carrying a term singleton, non-anomalous fetus, requiring continuous FHR monitoring in labour were consented to participate from the Jessop Wing maternity unit, Sheffield, UK. The trans-abdominal fetal ECG monitor was placed as per clinical protocol. During the monitoring session, clinicians were blinded to the computerised FHR parameters. We analysed the last hour of the FHR and its ability to predict umbilical arterial blood pH <7.20 using receiver operator characteristics (ROC) curves. RESULTS: Of 200 women, 137 cases were excluded as either the monitor did not work from the onset of labour (n = 30), clinical staff did not return or used the monitor on another patient (n = 37), umbilical cord blood not obtained (n = 25), FHR data not recorded within an hour of birth (n = 34) and other reasons (n = 11). In 63 cases included in the final analysis, the computer-derived FHR parameters did not show significant correlation with umbilical artery cord pH <7.20. Labour was associated with a significant increase in short and long term variation of FHR and number of deceleration (P<0.001). However, baseline FHR decreased significantly before delivery (P<0.001). CONCLUSIONS: The project encountered a number of challenges, with learning points crucial to informing the design of a large study to evaluate the potential place of intrapartum computerised FHR parameters, using abdominal fetal ECG monitor before its clinical utility and more widespread adoption can be ascertained.

RESUMO

The satisfaction of women with the birth experience has implications for the health and wellness of the women themselves and also of their newborn baby. The objectives of this study were to determine the factor structure of the Women's Views of Birth Labor Satisfaction Questionnaire (WOMBLSQ4) questionnaire on satisfaction with the attention received during birth delivery in Spanish women and to compare the level of satisfaction of pregnant women during the birth process with that in other studies that validated this instrument. A cross-sectional study using a self-completed questionnaire of 385 Spanish-speaking puerperal women who gave birth in the Public University Hospitals of Granada (Spain) was conducted. An exploratory factor analysis of the WOMBLSQ4 questionnaire was performed to identify the best fit model. Those items that showed commonalities higher than 0.50 were kept in the questionnaire. Using the principal components method, nine factors with eigenvalues greater than one were extracted after merging pain-related factors into a single item. These factors explain 90% of the global variance, indicating the high internal consistency of the full scale. In the model resulting from the WOMBLSQ4 questionnaire, its nine dimensions measure the levels of satisfaction of puerperal women with childbirth care. Average scores somewhat higher than those of the original questionnaire and close to those achieved in the study carried out in Madrid (Spain) were obtained. In clinical practice, this scale may be relevant for measuring the levels of satisfaction during childbirth of Spanish-speaking women.

RESUMO

INTRODUCTION: Identifying the factors contributing to maternal satisfaction is a proxy measure to improve the quality of care. It evaluates the health service provision by understanding maternal perceptions and expectations and promoting adherence to health services. This study aimed to identify the sociodemographic, obstetric, and medical factors contributing to labor satisfaction among postpartum women and examine the association between labor and postnatal satisfaction. METHODOLOGY: A cross-sectional study using systematic random sampling in a ratio of 1:5 based on the delivery list in a labor room in a tertiary hospital was applied. Information was obtained from medical records for sociodemographic characteristics and obstetric and medical histories. Face-to-face interviews were performed to obtain responses for Malay versions of the Women's Views of Birth Labour Satisfaction Questionnaire and the Women's Views of Birth Postnatal Satisfaction Questionnaire. Simple and general linear regression analyses were performed. RESULTS: A total of 110 participants responded, accounting for a response rate of 100%. High-risk color codes, the period of gestation, household income, and were significantly associated with maternal satisfaction during labor. The association between labor and postnatal satisfaction was significant. CONCLUSION: Identifying these associated factors and differences may lead to understanding and contributing to specific and targeted strategies for tackling issues related to maternal satisfaction.

RESUMO

PRÉSENTATION SOMMAIRE DE LA DEMANDE: Il a été demandé à l'INESSS de rechercher dans la littérature les données relatives à l'utilisation du protoxyde d'azote pendant l'accouchement en contexte de pandémie à la COVID-19 chez les femmes atteintes ou non du coronavirus afin d'en faire une utilisation optimale en contexte de pandémie et de crise. Le protoxyde d'azote (aussi appelé gaz hilarant ou oxyde nitreux) est un gaz incolore qui est utilisé, entre autres, en maintien de l'anesthésie générale ou comme analgésique (à dose subanesthésique) en obstétrique pendant l'accouchement. Lorsqu'il est utilisé comme analgésique, il doit être mélangé à de l'oxygène (50 %-50 %) et administré par inhalation par l'entremise d'un masque muni d'une valve à demande. Puisque ce gaz tend à dilater les cavités de l'organisme renfermant des gaz, le protoxyde d'azote serait contre-indiqué en présence d'air dans la plèvre, le péricarde ou le péritoine, de même que lors d'affection des voies aériennes chronique obstructive ou d'emphysème. MÉTHODOLOGIE: Questions d'évaluation: Quelles sont l'innocuité et les modalités d'utilisation du protoxyde d'azote pendant l'accouchement en contexte de pandémie à COVID-19? Critères de sélection: Population: Femmes atteintes ou non de la COVID-19. Intervention: Utilisation du protoxyde d'azote pendant l'accouchement Comparateur : Placebo ou autre analgésique Résultat d'intérêt : Innocuité, modalités d'utilisation. Types de documents retenus: Tout document contenant des informations pertinentes, que ce soit de la littérature scientifique ou de la littérature grise. Méthodes de recension: Date de recherch : 23 et 27 mars 2020. Une recherche rapide a été effectuée en utilisant les bases de données PubMed, MEDLINE, Embase, EBM Reviews et le moteur de recherche Google avec les mots-clés suivants: Coronavirus, pneumonia virus, 2019 ncov, COVID-19, nitrous Oxide, laughing gas, nitrogen protoxide, delivery, obstetric, childbirth, parturition, sage*-femme*, midwife*, midwives. Une recherche manuelle de la littérature a également été effectuée en consultant les sites Web des agences règlementaires, d'agences d'évaluation des technologies de la santé ainsi que ceux d'organismes gouvernementaux, d'associations ou ordres professionnels en lien avec le thème des travaux. Consultation menée: Aucune consultation d'experts n'a été menée dans le cadre de ces travaux. CONSTATS DE L'INESSS: Basé sur la documentation scientifique disponible au moment de sa rédaction, malgré l'incertitude existante dans cette documentation et dans la démarche utilisée de recension, il ressort que: Les recommandations liées à l'utilisation du protoxyde d'azote pendant l'accouchement chez les femmes confirmées ou suspectées COVID-19 sont divergentes selon les sociétés savantes ou organismes: Certains recommandent d'utiliser le protoxyde d'azote pendant l'accouchement en utilisant un filtre microbiologique pour prévenir la contamination du système d'inhalation du gaz; Certains recommandent d'utiliser le protoxyde d'azote pendant l'accouchement sans précision sur les précautions particulières; Certains recommandent d'évaluer les risques et bénéfices de l'utilisation du protoxyde d'azote pendant l'accouchement avant son utilisation vu les incertitudes entourant le nettoyage, les filtres à utiliser ainsi que le potentiel d'aérosolisation du produit; Certains ne mentionnent aucune opposition sur l'utilisation du protoxyde d'azote pendant l'accouchement puisqu'il n'existe aucune évidence que l'administration de ce médicament est une procédure pouvant générer des aérosols. Les incertitudes soulevées quant à la possibilité pour ce médicament de générer des aérosols rendent potentiellement nécessaire le port d'un équipement de protection approprié pour le personnel médical si utilisé par une personne avec statut COVID-19 positif ou suspecté. Or, ces équipements sont des ressources dont il serait judicieux de réserver l'usage pour des situations de nécessité absolue. De plus, le risque théorique de contamination par le virus du système d'administration du protoxyde d'azote est une considération importante.

RESUMO

Background: Obstructed or prolonged labor is a major cause of maternal deaths. Prolonged and obstructed labor contributed to 13% of global maternal deaths which can be reduced by proper utilization of a partograph during labor. Obstetric caregivers' use of the partograph during labor has paramount importance in identifying any deviation during labor. Even though partograph use is influenced by different factors as obtained from the literatures, the magnitude of partograph utilization and the factors associated with its use are not well determined in the health facilities of Wolaita Zone. Objective: To assess the magnitude of partograph utilization and factors that affect its utilization among obstetric caregivers in public health facilities of Wolaita Zone, Ethiopia, 2017. Methods: An institution-based cross-sectional study was conducted on obstetric caregivers. A pretested and structured questionnaire was used to collect data. Data was entered to EpiData version 3.01 and exported to SPSS version 23.0 for further analysis. Logistic regression analyses were used to see the association of different variables. Result: A total of 269 obstetric caregivers participated in the study. Among those who were utilizing the partograph, 193 (71.7%) routinely used it for all laboring mothers and 76 (28.3%) of participants reported that they do not routinely utilize it. Greater number of service years (AOR = 4.93, 95% CI: 1.53-15.88), on-the-job training (AOR = 0.16, 95% CI: 0.06-0.43), good knowledge (AOR = 3.35, 95% CI: 1.61-6.97), and favorable attitude towards partograph utilization (AOR = 2.99, 95% CI: 1.28-7.03) were significantly associated with partograph utilization. Conclusion and Recommendation. Partograph utilization among obstetric caregivers in the public health facilities was good. Greater years of work experience, in-service training, having good knowledge, and favorable attitude towards partograph utilization among obstetric caregivers independently determined partograph utilization. Provision of on-the-job training to make obstetric caregivers improve knowledge and skill on partograph utilization, maintaining caregivers' retention to decrease turnover by providing different incentives to more experienced obstetric care providers, and establishing favorable attitude could improve the proper use of the tool.

RESUMO

Many high-risk conditions of pregnancy are undetected until the time of delivery in low-income countries. We developed a point-of-care ultrasound training protocol for providers in rural Uganda to detect fetal distress or demise, malpresentation, multiple gestation, placenta previa, oligohydramnios and preterm delivery. This was a mixed-methods study to evaluate the 2-week training curriculum and trainees' ability to perform a standard scanning protocol and interpret ultrasound images. Surveys to assess provider confidence were administered pre-training, immediately after, and at 3-month follow up. Following lecture and practical demonstrations, each trainee conducted 25 proctored scans and were required to pass an observed structured clinical exam (OSCE). All images produced 8 weeks post course underwent blinded review by two ultrasound experts to assess image quality and to identify common errors. Key informant interviews further assessed perceptions of the training program and utility of point-of-care ultrasound. All interviews were audio recorded, transcribed, and reviewed by multiple readers using a content analysis approach. Twenty-three nurse/nurse midwives and two physicians from one district hospital and three health centers participated in the training curriculum. Confidence levels increased from an average of 1 point pre-course to over 6 points post-course for all measures (maximum of 7 points). Of 25 participants, 22 passed the OSCE on the first attempt (average score 89.4%). Image quality improved over time; the final error rate at week 8 was less than 5%, with an overall kappa of 0.8-1 for all measures between the two reviewers. Among the 12 key informant interviews conducted, key themes included a desire for more hands-on training and longer duration of training and challenges in balancing clinical duties with ability to attend training sessions. This study demonstrates that providers without previous ultrasound experience can detect high-risk conditions during labor with a high rate of quality and accuracy after training.

RESUMO

During gestation, uterine smooth muscle cells transition from a state of quiescence to one of contractility, but the molecular mechanisms underlying this transition at a genomic level are not well-known. To better understand these events, we evaluated the epigenetic landscape of the mouse myometrium during the pregnant, laboring, and postpartum stages. We generated gestational time point-specific enrichment profiles for histone H3 acetylation on lysine residue 27 (H3K27ac), histone H3 trimethylation of lysine residue 4 (H3K4me3), and RNA polymerase II (RNAPII) occupancy by chromatin immunoprecipitation with massively parallel sequencing (ChIP-seq), as well as gene expression profiles by total RNA-sequencing (RNA-seq). Our findings reveal that 533 genes, including known contractility-driving genes (Gap junction alpha 1 [Gja1], FBJ osteosarcoma oncogene [Fos], Fos-like antigen 2 [Fosl2], Oxytocin receptor [Oxtr], and Prostaglandin G/H synthase 2 (Ptgs2), for example), are up-regulated at day 19 during active labor because of an increase in transcription at gene bodies. Labor-associated promoters and putative intergenic enhancers, however, are epigenetically activated as early as day 15, by which point the majority of genome-wide H3K27ac or H3K4me3 peaks present in term laboring tissue is already established. Despite this early exhibited histone signature, increased noncoding enhancer RNA (eRNA) production at putative intergenic enhancers and recruitment of RNAPII to the gene bodies of labor-associated loci were detected only during labor. Our findings indicate that epigenetic activation of the myometrial genome precedes active labor by at least 4 days in the mouse model, suggesting that the myometrium is poised for rapid activation of contraction-associated genes in order to exit the state of quiescence.

RESUMO

To evaluate labor and delivery complications and delivery modes between physicians and white-collar workers in Taiwan, this retrospective population-based study used data from Taiwan's National Health Insurance Research Database. We compared 1530 physicians aged 25 to 50 years old who worked and had singleton births between 2007 and 2013 with 3060 white-collar workers matched by age groups, groups of monthly insured payroll-related premiums, previous cesarean delivery, perinatal history anemia, and gestational diabetes mellitus. The logistic regression models were used to assess the labor and delivery complications between the two groups. Multivariate analysis revealed that physicians had a significantly higher risk of placenta previa (odds ratio (OR) 1.35, 95% confidence interval (CI) 1.08-1.69) and other malpresentation (OR 1.86, 95% CI 1.45-2.39) than white-collar workers, whereas they had a significantly lower risk of placental abruption (OR 0.53, 95% CI 0.40-0.71), preterm delivery (OR 0.75, 95% CI 0.61-0.92), and premature rupture of membranes (OR 0.72, 95% CI 0.59-0.88). Increased risks of some adverse labor and delivery complications were observed among physicians, when compared to white-collar workers. These findings suggest that working women should take preventative action to manage occupational risks during pregnancy.

RESUMO

OBJECTIVE: To compare synthetic oxytocin infusion regimens used during labour, calculate the International Units (IU) escalation rate and total amount of IU infused over eight hours. DESIGN: Observational study. SETTING: Twelve countries, eleven European and South Africa. SAMPLE: National, regional or institutional-level regimens on oxytocin for induction and augmentation labour. METHODS: Data on oxytocin IU dose, infusion fluid amount, start dose, escalation rate and maximum dose were collected. Values for each regimen were converted to IU in 1000ml diluent. One IU corresponded to 1.67µg for doses provided in grams/micrograms. IU hourly dose increase rates were based on escalation frequency. Cumulative doses and total IU amount infused were calculated by adding the dose administered for each previous hour. Main Outcome Measures Oxytocin IU dose infused. RESULTS: Data were obtained on 21 regimens used in 12 countries. Details on the start dose, escalation interval, escalation rate and maximum dose infused were available from 16 regimens. Starting rates varied from 0.06 IU/hour to 0.90 IU/hour, and the maximum dose rate varied from 0.90 IU/hour to 3.60 IU/hour. The total amount of IU oxytocin infused, estimated over eight hours, ranged from 2.38 IU to 27.00 IU, a variation of 24.62 IU and an 11-fold difference. CONCLUSION: Current variations in oxytocin regimens for induction and augmentation of labour are inexplicable. It is crucial that the appropriate minimum infusion regimen is administered because synthetic oxytocin is a potentially harmful medication with serious consequences for women and babies when inappropriately used. Estimating the total amount of oxytocin IU received by labouring women, alongside the institution's mode of birth and neonatal outcomes, may deepen our understanding and be the way forward to identifying the optimal infusion regimen.

RESUMO

BACKGROUND: Psychological aspects of labor and birth have received little attention within maternity care service planning or clinical practice. The aim of this paper is to propose a model demonstrating how neurohormonal processes, in particular oxytocinergic mechanisms, not only control the physiological aspects of labor and birth, but also contribute to the subjective psychological experiences of birth. In addition, sensory information from the uterus as well as the external environment might influence these neurohormonal processes thereby influencing the progress of labor and the experience of birth. METHODOLOGY: In this new model of childbirth, we integrated the findings from two previous systematic reviews, one on maternal plasma levels of oxytocin during physiological childbirth and one meta-synthesis of women´s subjective experiences of physiological childbirth. FINDINGS: The neurobiological processes induced by the release of endogenous oxytocin during birth influence maternal behaviour and feelings in connection with birth in order to facilitate birth. The psychological experiences during birth may promote an optimal transition to motherhood. The spontaneous altered state of consciousness, that some women experience, may well be a hallmark of physiological childbirth in humans. The data also highlights the crucial role of one-to-one support during labor and birth. The physiological importance of social support to reduce labor stress and pain necessitates a reconsideration of many aspects of modern maternity care. CONCLUSION: By listening to women's experiences and by observing women during childbirth, factors that contribute to an optimized process of labor, such as the mothers' wellbeing and feelings of safety, may be identified. These observations support the integrative role of endogenous oxytocin in coordinating the neuroendocrine, psychological and physiological aspects of labor and birth, including oxytocin mediated. decrease of pain, fear and stress, support the need for midwifery one-to-one support in labour as well as the need for maternity care that optimizes the function of these neuroendocrine processes even when birth interventions are used. Women and their partners would benefit from understanding the crucial role that endogenous oxytocin plays in the psychological and neuroendocrinological process of labor.

RESUMO

BACKGROUND: Continuous epidural infusion (CEI) is commonly used for labour analgesia, but concerns over potential motor block, second-stage labour complications, and ineffective analgesia in late labour have prompted examining intermittent epidural bolus (IEB) as an alternative. However, evidence comparing these modalities is conflicting. The meta-analysis evaluates the analgesic efficacy of CEI vs IEB. METHODS: Databases were searched for trials comparing CEI to IEB for labour analgesia. The two co-primary outcomes were risk of breakthrough pain and difference in area under the curve (AUC) for pain scores during the first 4 h post-epidural initiation. Local anaesthetic consumption, maternal outcomes (i.e. delivery mode, labour duration, and maternal satisfaction), and side-effects of epidural analgesia were also evaluated. Results were pooled using random-effects modelling. Trial sequential analysis (TSA) was used to evaluate evidence reliability. RESULTS: Twenty-seven studies (3133 patients) were analysed. Compared with CEI, IEB decreased risk of breakthrough pain by 38% (risk ratio [95% confidence interval {CI}] of 0.62 [0.48, 0.81]; P=0.0004; I2=47%; 1164 patients) and reduced AUC of pain during the 4 h interval by 32.9% (mean difference [95% CI] of -16.7 mm h-1 [-18.9, -14.4]; P<0.0001; 1638 patients). Intermittent epidural bolus enhanced maternal satisfaction, shortened labour duration, decreased motor block, and reduced local anaesthetic consumption. The difference between the two groups was not statistically significant for epidural side-effects or mode of delivery. The TSA indicated adequate power for reliable inferences. CONCLUSIONS: Intermittent epidural bolus provides improved labour pain control during the first 4 h after epidural initiation with less breakthrough pain. Moderate- to high-quality evidence of intermittent epidural bolus superiority support its use as a safe and effective continuous epidural infusion alternative for labour analgesia.
