Obstructed Labor at a Tertiary Hospital in Nigeria: A Six-Year Review

Introduction: Unlike most developed countries, obstructed labor with a dead fetus is still a reality in many developing countries, and it is a well-known cause of maternal and perinatal morbidity and mortality. Objective: To highlight the characteristics of patients presenting with obstructed labor at a tertiary hospital and determine fetomaternal outcomes. Methodology: A retrospective descriptive study of 45 cases of obstructed labor that were managed in a tertiary hospital from January 2009 to December 2014. Relevant information was extracted from patients’ case files, and the data obtained were analyzed. Results: Obstructed labor constituted 0.75% of all deliveries. All patients were referred in, and thirty (2/3) of them were nulliparous, while 25 (55.6%) were between the ages of 16 and 25. Forty-one (91.1%) of the patients were delivered by emergency caesarean section, while four patients had exploratory laparotomy with uterine repair and bilateral tubal ligation. Thirty-eight (84.5%) of the babies weighed between 2.6-4kg and five (11.1%) weighed more than 4kg. Most of the patients, 91.1%, had prolonged hospital stay with 25% staying over 3 weeks postpartum before being discharged. Eight (17.8%) suffered severe birth asphyxia, and there were five perinatal and two maternal mortalities. The commonest complication was puerperal sepsis. Conclusion: The study showed obstructed labor remains a cause of perinatal and maternal morbidity and mortality. Effective use of partographs in the peripheral centers, where all the women came from, would ensure early referral before labor became obstructed.

Impact of maternal body mass index on delivery complications and recurrent pregnancy loss (RPL)

Maternal Body Mass Index (BMI) is a crucial predictor of obstetric and delivery-related complications, significantly affecting maternal and neonatal outcomes. As global obesity rates continue to rise, the impact of elevated maternal BMI on pregnancy has garnered increasing attention. This comprehensive review examines the association between maternal BMI and various pregnancy complications, including gestational diabetes mellitus (GDM), hypertensive disorders, labor dystocia, cesarean section (C-section), postpartum hemorrhage (PPH), and adverse neonatal outcomes such as macrosomia. The aim of this review is to examine the impact of maternal Body Mass Index (BMI) on pregnancy and delivery outcomes, with a focus on identifying key complications associated with elevated maternal BMI and exploring the underlying mechanisms. As global obesity rates continue to rise, understanding the influence of maternal BMI on obstetric and neonatal outcomes is crucial for developing effective management strategies. This review synthesizes current research on the relationship between maternal BMI and complications such as gestational diabetes mellitus (GDM), hypertensive disorders, labor dystocia, cesarean section (C-section), postpartum hemorrhage (PPH), and adverse neonatal outcomes, including macrosomia. The review also delves into the physiological mechanisms, including insulin resistance, chronic inflammation, and altered uterine contractility, that contribute to these complications. Clinical implications are discussed, emphasizing the importance of preconception counselling, individualized weight management during pregnancy, and interdisciplinary care to optimize outcomes. The conclusion highlights Maternal BMI is a critical factor influencing pregnancy outcomes. Obesity increases the risk of delivery complications and RPL, while underweight status is associated with preterm birth, LBW, and RPL. Addressing maternal BMI through preconception care and continuous monitoring during pregnancy is essential for improving maternal and fetal health outcomes.

Prevalence rate, perinatal outcome and causes of obstructed labour A hospital based study

Background and objective: Obstructed labor is a serious intrapartum emergency especially seen in women deprived of modern healthcare delivery. It could be one of the major reasons of morbidity and mortality for both the mother and the newborn. This study was aimed at determine the rate, causes and perinatal outcomes of women who have obstructive labor during delivery. Methods: A cross-sectional study that was conducted on 150 delivering women having obstructed labor at Maternity Teaching Hospital, Erbil city, Kurdistan Region, Iraq from 1st of March 2021 to 1st of March 2022 The rate, socio-demographic characters (age, parity, smoking, antenatal care, residency, education level, gestational age), causes like (malposition, malpresntation, cephalo-pelvic desorption) and perinatal outcomes were recorded. Results: of 9137 labor, 150 were obstructed labor; the total rate was 1.6% during the period of the study. There was no statistically significant associated between socio-demographic characters like age, smoking, gestational age, residency, education level, antenatal care and obstructed labor except multiparity that has significant association. There was a significant association between the causes like cephalo-pelvic disproportion, malposition, malprsentation, sized baby and having fracture to spine and pelvis or trauma and obstructed labor. Also there was no statistically significant associated between Apgar score and admission to neonatal intensive care unit. Conclusion: Obstructive labor is common during labor. Malposition was most common the cause of obstructive labor and parity has association with it too. Neonatal morbidity and mortality are dependent on the type of presentation.

AIDA (Artificial Intelligence Dystocia Algorithm) in Prolonged Dystocic Labor: Focus on Asynclitism Degree.

Asynclitism, a misalignment of the fetal head with respect to the plane of passage through the birth canal, represents a significant obstetric challenge. High degrees of asynclitism are associated with labor dystocia, difficult operative delivery, and cesarean delivery. Despite its clinical relevance, the diagnosis of asynclitism and its influence on the outcome of labor remain matters of debate. This study analyzes the role of the degree of asynclitism (AD) in assessing labor progress and predicting labor outcome, focusing on its ability to predict intrapartum cesarean delivery (ICD) versus non-cesarean delivery. The study also aims to assess the performance of the AIDA (Artificial Intelligence Dystocia Algorithm) algorithm in integrating AD with other ultrasound parameters for predicting labor outcome. This retrospective study involved 135 full-term nulliparous patients with singleton fetuses in cephalic presentation undergoing neuraxial analgesia. Data were collected at three Italian hospitals between January 2014 and December 2020. In addition to routine digital vaginal examination, all patients underwent intrapartum ultrasound (IU) during protracted second stage of labor (greater than three hours). Four geometric parameters were measured using standard 3.5 MHz transabdominal ultrasound probes: head-to-symphysis distance (HSD), degree of asynclitism (AD), angle of progression (AoP), and midline angle (MLA). The AIDA algorithm, a machine learning-based decision support system, was used to classify patients into five classes (from 0 to 4) based on the values of the four geometric parameters and to predict labor outcome (ICD or non-ICD). Six machine learning algorithms were used: MLP (multi-layer perceptron), RF (random forest), SVM (support vector machine), XGBoost, LR (logistic regression), and DT (decision tree). Pearson's correlation was used to investigate the relationship between AD and the other parameters. A degree of asynclitism greater than 70 mm was found to be significantly associated with an increased rate of cesarean deliveries. Pearson's correlation analysis showed a weak to very weak correlation between AD and AoP (PC = 0.36, p < 0.001), AD and HSD (PC = 0.18, p < 0.05), and AD and MLA (PC = 0.14). The AIDA algorithm demonstrated high accuracy in predicting labor outcome, particularly for AIDA classes 0 and 4, with 100% agreement with physician-practiced labor outcome in two cases (RF and SVM algorithms) and slightly lower agreement with MLP. For AIDA class 3, the RF algorithm performed best, with an accuracy of 92%. AD, in combination with HSD, MLA, and AoP, plays a significant role in predicting labor dystocia and labor outcome. The AIDA algorithm, based on these four geometric parameters, has proven to be a promising decision support tool for predicting labor outcome and may help reduce the need for unnecessary cesarean deliveries, while improving maternal-fetal outcomes. Future studies with larger cohorts are needed to further validate these findings and refine the cut-off thresholds for AD and other parameters in the AIDA algorithm.

Novel use of the rectus abdominus muscle flap for vaginal reconstruction in complex obstetric fistula repair: A case series.

Globally, obstetric fistula is a tragic outcome following obstructed labour. Failure of complex repair and post-operative incontinence are common. We describe an innovative surgical technique incorporating the rectus abdominus flap at the time of fistula repair. Retrospective case series. Malawi, Fistula Care Centre. Patients were followed for 3 months after discharge to determine continence and healing. Five of six patients were continent at 3 months and one was lost to follow-up by dry at a one month post-operative phone call. There were no major complications. The rectus abdominus flap may be a useful adjunct to repair of complex obstetric fistula.

Evaluation of Statewide Program to Reduce Cesarean Deliveries Among Nulliparous Individuals With Singleton Pregnancies at Term Gestation in Vertex Presentation.

To evaluate the effect of statewide efforts to reduce nulliparous, term, singleton, vertex (NTSV) cesarean delivery rates in California. This was a population-based study of all NTSV births in California from 2015 to 2019. In 2015, all California hospitals with NTSV cesarean delivery rates above the 23.9% Healthy People 2020 target were invited to join a CMQCC (California Maternal Quality Care Collaborative)-sponsored, 3-year, multifaceted collaborative or a system-level quality collaborative to safely support vaginal birth. We examined the cesarean delivery rate overall and by participation or nonparticipation in a collaborative program. Secondarily, for hospitals that started with an NTSV cesarean delivery rate above 23.9%, we compared patient-level, hospital-level, and obstetric management characteristics between hospitals that met the Healthy People 2020 target (cesarean delivery rate below 23.9%) in 2019 and those that did not. There were 758,268 NTSV births at 238 hospitals. Annual mean NTSV cesarean delivery rates decreased among all racial and ethnic groups statewide and among all patients, regardless of payer, maternal age, or body mass index (BMI). The decrease in cesarean delivery was driven largely by a decrease in the frequency of cesarean delivery performed for labor dystocia (14.9% in 2015 to 12.8% in 2019) and from cesarean delivery before the onset of labor (4.2% in 2015 to 3.3% in 2019). For hospitals that started with an NTSV cesarean delivery rate above 23.9%, NTSV cesarean delivery rates among 80 hospitals participating in the CMQCC had a mean±SD decline of 6.9±5.9%, 13 hospitals participating in the system-level collaborative had a 5.0±4.5% decline, and those not participating in any collaborative had a 2.1±6.0% decline. In multivariable analysis, there was no association between meeting the Healthy People target and any of the hospital-level factors or aggregated patient-level characteristics. Rates of induction of labor increased in both groups and were not associated with a change in cesarean delivery rates. Hospitals in California between 2015 and 2019 with a wide variation in institutional and patient characteristics successfully reduced their NTSV cesarean delivery rates. Reduction in the NTSV cesarean delivery rate at hospitals that started above the Healthy People target was not associated with differences in patient characteristics but rather a reduction in cesarean deliveries for labor dystocia and cesarean deliveries performed before the onset of labor.

The global burden, risk and inequality of maternal obstructed labor and uterine rupture from 1990 to 2019

BackgroundObstructed labor (OL) and uterine rupture (UR) are common obstetric complications. This study explored the burden, risk factors, decomposition, and health inequalities associated with OL and UR to improve global maternal health.MethodsThis was a cross-sectional analysis study including data on OL and UR from the Global Burden of Diseases, and Risk Factors Study (GBD) 2019. The main outcome measures included the number and age-standardized rate (ASR) of incidence, disability-adjusted life years (DALYs), prevalence, and deaths.ResultsThe global burden of OL and UR has declined, with a decrease in incidence (number in 2019: 9,410,500.87, 95%UI 11,730,030.94 to 7,564,568.91; ASR in 2019: 119.64 per 100,000, 95%UI 149.15 to 96.21; estimated annual percentage change [EAPC] from 1990 to 2019: -1.34, 95% CI -1.41 to -1.27) and prevalence over time. However, DALYs (number in 2019: 999,540.67, 95%UI 1,209,749.35 to 817,352.49; ASR in 2019: 12.92, 95%UI 15.63 to 10.56; EAPC from 1990 to 2019: -0.91, 95% CI -1.26 to -0.57) and deaths remain significant. ASR of DALYs increased for the 10–14 year-old age group (2.01, 95% CI 1.53 to 2.5), the 15–19 year-old age group (0.07, 95% CI -0.47 to 0.61), Andean Latin America (3.47, 95% CI 3.05 to 3.89), and Caribbean (4.16, 95% CI 6 to 4.76). Iron deficiency was identified as a risk factor for OL and UR, and its impact varied across different socio-demographic indices (SDIs). Decomposition analysis showed that population growth primarily contributed to the burden, especially in low SDI regions. Health inequalities were evident, the slope and intercept for DALYs were − 47.95 (95% CI -52.87 to -43.02) and − 29.29 (95% CI -32.95 to -25.63) in 1990, 39.37 (95%CI 36.29 to 42.45) and 24.87 (95%CI 22.56 to 27.18) in 2019. Concentration indices of ASR-DALYs were − 0.2908 in 1990 and − 0.2922 in 2019.ConclusionThis study highlights the significant burden of OL and UR and emphasizes the need for continuous efforts to reduce maternal mortality and morbidity. Understanding risk factors and addressing health inequalities are crucial for the development of effective interventions and policies to improve maternal health outcomes globally.

Short stature and vaginal dinoprostone as independent predictors of composite maternal-newborn adverse outcomes in induction of labor after one previous cesarean: a retrospective cohort study

BackgroundThe rates of labor induction and cesarean delivery is rising worldwide. With the confluence of these trends, the labor induction rate in trials of labor after cesarean can be as high as 27-32.7%. Induction of labor after one previous cesarean (IOLAC) is a high-risk procedure mainly due to the higher risk of uterine rupture. Nevertheless, the American College of Obstetricians and Gynecologists considers IOLAC as an option in motivated and informed women in the appropriate care setting. We sought to identify predictors of a composite of maternal and newborn adverse outcomes following IOLAC.MethodsThe electronic medical records of women who delivered between January 2018 to September 2022 in a Malaysian university hospital were screened to identify cases of IOLAC. A case is classified as a composite adverse outcome if at least one of these 11 adverse outcomes of delivery blood loss ≥ 1000 ml, uterine scar complications, cord prolapse or presentation, placenta abruption, maternal fever (≥ 38 0C), chorioamnionitis, intensive care unit (ICU) admission, Apgar score < 7 at 5 min, umbilical artery cord artery blood pH < 7.1 or base excess ≤-12 mmol/l, and neonatal ICU admission was present. An unplanned cesarean delivery was not considered an adverse outcome as the practical management alternative for a clinically indicated IOLAC was a planned cesarean. Bivariate analysis of participants’ characteristics was performed to identify predictors of their association with composite adverse outcome. Characteristics with crude p < 0.10 on bivariate analysis were incorporated into a multivariable binary logistic regression analysis model.ResultsElectronic medical records of 19,064 women were screened. 819 IOLAC cases and 98 cases with composite adverse outcomes were identified. Maternal height, ethnicity, previous vaginal delivery, indication of previous cesarean, indication for IOLAC, and method of IOLAC had p < 0.10 on bivariate analysis and were incorporated into a multivariable binary logistic regression analysis. After adjustment, only maternal height and IOLAC by vaginal dinoprostone compared to Foley balloon remained significant at p < 0.05. Post hoc adjusted analysis that included all unplanned cesarean as an added qualifier for composite adverse outcome showed higher body mass index, short stature (< 157 cm), not of Chinese ethnicity, no prior vaginal delivery, prior cesarean indicated by labor dystocia, and less favorable Bishop score (< 6) were independent predictors of the expanded composite adverse outcome.ConclusionShorter women and IOLAC by vaginal dinoprostone compared to Foley balloon were independently predictive of composite of adverse outcome.

Investigating the Rates of Cesarean and Vaginal Deliveries Across Different Races and Ethnicities at Ascension St. Vincent Indianapolis

Background: Cesarean section remains one of the most common surgical procedures for women in the United States. Previous studies have shown higher rates in African-American and Asian women and lower rates among White and Hispanic women. The objective of this study is to investigate the rates of cesarean and vaginal deliveries across different races and ethnicities as well as languages spoken at our institution. Methods: A retrospective chart review was completed of nulliparous women with term, singleton, and vertex deliveries between 2015-2020. Factors increasing risk for cesarean or contraindications for vaginal delivery were excluded. Binomial logistic regression analysis was used to evaluate mode and delivery indications among racial and ethnic groups as well as among primary languages spoken. Results: White was the largest race reported (66.4%), followed by Black or African American (27.6%), then Asian (3.6%). “Other” or rather, “Non-Hispanic”, was the largest ethnicity reported (85.2%). Cross-tabulating race and ethnicities, the largest group was non-Hispanic White (54%), followed by Non-Hispanic Black or African American (26.5%), then Hispanic or Latino (10.8%). Primary languages were English (91.0%), followed by Spanish (5.7%), then Other (3.3%). Preliminary results showed statistically significant differences in age, BMI, insufficient prenatal care, and specific labor dystocia indications among different races and ethnicities. There were also differences among English vs Spanish vs “Other” languages but not in rates of vaginal and cesarean deliveries. The binomial logistic regression analysis showed that BMI and most labor dystocia positively correlated with cesarean delivery, whereas race/ethnicity, language, age, insufficient prenatal care, and induction status did not change the outcome. Conclusions: Racial and ethnic differences in mode of delivery have been previously documented in previous studies; although we did not find this at our institution. Our findings, however, show a positive relationship between Body Mass Index (BMI) and cesarean delivery, as has previously been documented.

Prediction of spontaneous vaginal delivery in the prolonged second stage using the delta angle of progression

It is clinically challenging to determine when to intervene in the prolonged second stage. Although individualized prediction of spontaneous vaginal delivery is crucial to avoid maternal and neonatal complications associated with operative deliveries, the approach has not been fully established. We aimed to evaluate the predictability of spontaneous vaginal delivery using the difference in angle of progression between pushing and rest, delta angle of progression, to establish a novel method to predict spontaneous vaginal delivery during the prolonged second stage in nulliparous women with epidural anesthesia. We retrospectively analyzed deliveries of nulliparous women with epidural anesthesia between September 2018 and October 2023. Women were included if their delta angle of progression during the second stage was available. Operative deliveries were defined as the cases that required forceps, vacuum, and cesarean deliveries due to labor arrest. Women requiring operative deliveries due to fetal and maternal concerns, or women with fetal occiput posterior presentation were excluded. The second stage was stratified into the prolonged second stage, the period after 3 hours in the second stage, and the normal second stage, the period from the beginning until the third hour of the second stage. The association of the delta angle of the progression measured during each stage with spontaneous vaginal delivery and operative deliveries was investigated. Furthermore, the predictability of spontaneous vaginal delivery was evaluated by combining the delta and rest angle of progression. A total of 129 women were eligible for analysis. The delta angle of progression measured during the prolonged second stage and normal second stage were significantly larger in women who achieved spontaneous vaginal delivery compared to operative deliveries (p<.001 and p<.05, respectively). During the prolonged second stage, a cutoff of 18.8 derived from the receiver operative characteristic curves in the context of the delta angle of progression predicted the possibility of spontaneous vaginal delivery (sensitivity, 81.8%; specificity, 60.0%; AUC, 0.76). Combining the rest angle of progression (>140) and delta angle of progression (>18.8) also provided quantitative prediction of spontaneous vaginal delivery (sensitivity, 86.7%; specificity, 70.0%; AUC, 0.80). The delta angle of progression alone or in combination with the rest angle of progression can be used to predict spontaneous vaginal delivery in the second stage in nulliparous women with epidural anesthesia. Quantitative analysis of the effect of pushing using the delta angle of progression provides an objective guide to assist with an assessment of labor dystocia in the prolonged second stage on an individualized basis, which may optimize labor management in the prolonged second stage by reducing neonatal and maternal complications related to unnecessary operative deliveries and prolonged second stage of labor.

PROLAPSUS GENITAUX : ASPECTS EPIDEMIOLOGIQUES DIAGNOSTIQUES ET THERAPEUTIQUES A PROPOS DE 58 CAS.

Genital prolapse is a permanent or stressful exit through the vagina of one or more components of the pelvic viscera. It is frequent in elder, multiparous and menopausal women. Its diagnosis is clinical and the treatment essentially surgical. The recurrent rate is significant. The aim of our study was to describe the epidemiological, diagnostic, therapeutic and prognostic aspects of genital prolapse in the general surgery department of Aristide Le Dantec Teaching Hospital in Dakar. Materials and method. It was a retrospective study interesting genital prolapse operated in the period of 10 years 6 months from January 1, 2008 to July 31, 2019. The studied parameters were epidemiological data, clinical data, classification, paraclinical data, surgical treatment and results. Results. We collected 58 cases of genital prolapse represented 0.55% of the surgical activity during the study period. The mean age was 59 years with extremes of 25 and 89 years. The most represented age group was 61 and 75 years of age with 25 cases (43.1%). Patients over the age of 60 represented 50.1%. We had 46 cases of multiparous (79.3%) and 11 cases of pauciparous (19%). Postmenopausal patients represented 44 cases (75.8%). The majority of our patients, 67.2%, were housewives with the notion of carrying a heavy charge. All of our patients delivered vaginally with 13.3% obstructed labor. Eight patients (13.7%) had a history of pelvic surgery. The mean duration of symptom was 8 months with extremes of 10 days and 40 years. The functional signs were dominated by the sensation of a vaginal mass in 53 cases (91.3%). We had 13 cases of urinary incontinence (22.4%) and all associated with a cystocel. The three-stage genital prolapse was the most frequent (43.1%). The grade III was the most frequent (43.3%). Pelvic ultrasound was performed in 74.1%. The vaginal route was performed in 56 cases (96%). The triple perineal intervention with hysterectomy was the most performed procedure in 23 cases or 41%. Two cases (4%) of uterine promontofixation by laparotomy was done. The mean of hospital stay was 4 days. Morbidity was 4 cases (6.8%) and was dominated by urinary tract infection. Six cases of recurrence were noted (0.3%). Conclusion:Although the clinical diagnosis is easy, management is uncodified and would require the establishment of a well questionnary. Keywords: genital prolapse, urinary incontinence, vaginal surgery

Modern Comparision of Asadhya Mudha Garbha Lakshanas and Obstructed Labour in Brif

Modern Comparision of Asadhya Mudha Garbha Lakshanas and Obstructed Labour in Brif

Obstetrical Constraints and the Origin of Extended Postnatal Brain Maturation in Hominin Evolution.

The origin of difficult birth is still a matter of debate in obstetrics. Recent studies hypothesized that early hominins already experienced obstructed labor even with reduced neonatal head sizes. The aim of this work is to test this hypothesis using an extant obstetrical sample with known delivery outcomes. Three delivery outcomes (i.e., instrument-assisted, Caesarean section, and vaginal birth) were evaluated using a discriminant analysis based on 131 mother-baby dyads and 36 feto-pelvic variables. This obstetrical sample was compared with 20 australopithecine "dyads" generated from the combination of six pelvic reconstructions (three for Australopithecus afarensis, two for A. africanus, and one for A. sediba) and three fetal head size estimations. The obstetrical analysis revealed that dystocic births can be predicted by pelvic features such as an anteroposteriorly flattened pelvic inlet. Australopithecines shared these pelvic morphologies with humans and had eutocic birth only for infants of 110 g brain size or smaller, equaling a human-like neonatal/adult brain size ratio of 25-28%. Although birth mechanism cannot be deduced, the newborn/adult brain size ratio was likely more human-like than previously thought, suggesting that australopithecines were secondarily altricial to circumvent instances of obstructed labor and subsequently require a prolonged postnatal brain growth period, implying some aspects of life history pattern similar to modern humans.

Shoulder Dystocia: A Comprehensive Literature Review on Diagnosis, Prevention, Complications, Prognosis, and Management.

The term dystocia refers to labor characterized by a slow progression with delayed rates or even pauses in the dilation of the cervix or the descent of the fetus. Dystocia describes the deviation from the limits that define a normal birth and is often used as a synonym for the term pathological birth. Shoulder dystocia, also known as the manual exit of the shoulders during vaginal delivery on cephalic presentation, is defined as the "failure of the shoulders to spontaneously traverse the pelvis after delivery of the fetal head". This means that obstetric interventions are necessary to deliver the fetus's body after the head has been delivered, as gentle traction has failed. Abnormal labor (dystocia) is expressed and represented in partograms or by the prolongation of the latent phase or by slowing and pausing in the phases of cervical dilatation and fetal descent. While partograms are helpful in visualizing the progress of labor, regular use of them has not been shown to enhance obstetric outcomes considerably, and no partogram has been shown to be superior to others in comparative trials. Dystocia can, therefore, appear in any phase of the evolution of childbirth, so it is necessary to simultaneously assess all the factors that may contribute to its abnormal evolution, that is, the forces exerted, the weight, the shape, the presentation and position of the fetus, the integrity and morphology of the pelvis, and its relation to the fetus. When this complication occurs, it can result in an increased incidence of maternal morbidity, as well as an increased incidence of neonatal morbidity and mortality. Although several risk factors are associated with shoulder dystocia, it has proven impossible to recognize individual cases of shoulder dystocia in practice before they occur during labor. Various guidelines have been published for the management of shoulder dystocia, with the primary goal of educating the obstetrician and midwife on the importance of a preplanned sequence of maneuvers, thereby reducing maternal and neonatal morbidity and mortality.

WORKING WITH MIDWIVES TO IMPROVE MATERNAL HEALTH IN RURAL GHANA

This paper describes the implementation and evaluation of a safe motherhood project in rural Ghana. This project included a partograph and emergency skills program for rural midwives, training and monitoring traditional birth attendants (TBAs), a blood bank and an emergency obstetric transport service. The midwives' roles in caring for women in rural health centres, training and monitoring traditional birth attendants (TBAs) and in emergency obstetric transport are described. In this rural area of Ghana TBAs are responsible for approximately 65% of women in the district during birth. It is important to include them in projects to improve maternal health. The results of process evaluation showed that the rural maternal health system was improved by the project activities through a good communication system, better support for rural midwives, better integration of traditional birth attendants into the health care system and more community involvement. Outcomes included an increase in the number of referrals of women with risk factors and complications to the district hospital, no cases of prolonged obstructed labour in the group of mothers cared for by rural midwives and trained TBAs, a comprehensive recording and reporting system for women cared for by TBAs, and a well established emergency obstetric transport service. Integration of the TBAs into the health care system has had positive effects on TBA practice and morale. However, some TBAs had problems receiving remuneration for their work due to cultural beliefs and practices. The authors conclude that community education and participation are key components of safe motherhood projects.

Physiological plateaus during normal labor and birth: A novel definition.

Diagnoses of labor dystocia, and subsequent labor augmentation, make one of the biggest contributions to childbirth medicalization, which remains a key challenge in contemporary maternity care. However, labor dystocia is poorly defined, and the antithetical concept of physiological plateaus remains insufficiently explored. To generate a definition of physiological plateaus as a basis for further research. This qualitative study applied grounded theory methods and comprised interviews with 20 midwives across Australia, conducted between September 2020 and February 2022. Data were coded in a three-phase approach, starting with inductive line-by-line coding, which generated themes and subthemes, and finally, through axial coding. Physiological plateaus represent a temporary slowing of one or multiple labor processes and appear to be common during childbirth. They are reported throughout the entire continuum of labor, typically lasting between a few minutes to several hours. Their etiology/function appears to be a self-regulatory mechanism of the mother-infant dyad. Physiological plateaus typically self-resolve and are followed by a self-resumption of labor. Women with physiological plateaus during labor appear to experience positive birth outcomes. Despite appearing to be common, physiological plateaus are insufficiently recognized in contemporary childbirth discourse. Consequently, there seems to be a significant risk of misinterpretation of physiological plateaus as labor dystocia. While findings are limited by the qualitative design and require validation through further quantitative research, the proposed novel definition provides an important starting point for further investigation. A better understanding of physiological plateaus holds the potential for a de-medicalization of childbirth through preventing unjustified labor augmentation.

Localization of Catecholaminergic Neurofibers in Pregnant Cervix as a Possible Myometrial Pacemaker.

In eutocic labor, the autonomic nervous system is dominated by the parasympathetic system, which ensures optimal blood flow to the uterus and placenta. This study is focused on the detection of the quantitative presence of catecholamine (C) neurofibers in the internal uterine orifice (IUO) and in the lower uterine segment (LUS) of the pregnant uterus, which could play a role in labor and delivery. A total of 102 women were enrolled before their submission to a scheduled cesarean section (CS); patients showed a singleton fetus in a cephalic presentation outside labor. During CS, surgeons sampled two serial consecutive full-thickness sections 5 mm in depth (including the myometrial layer) on the LUS and two randomly selected samples of 5 mm depth from the IUO of the cervix. All histological samples were studied to quantify the distribution of A nerve fibers. The authors demonstrated a significant and notably higher concentration of A fibers in the IUO (46 ± 4.8) than in the LUS (21 ± 2.6), showing that the pregnant cervix has a greater concentration of A neurofibers than the at-term LUS. Pregnant women's mechanosensitive pacemakers can operate normally when the body is in a physiological state, which permits normal uterine contractions and eutocic delivery. The increased frequency of C neurofibers in the cervix may influence the smooth muscle cell bundles' activation, which could cause an aberrant mechano-sensitive pacemaker activation-deactivation cycle. Stressful circumstances (anxiety, tension, fetal head position) cause the sympathetic nervous system to become more active, working through these nerve fibers in the gravid cervix. They might interfere with the mechano-sensitive pacemakers, slowing down the uterine contractions and cervix ripening, which could result in dystocic labor.

Intention to Use Mobile-Based Partograph and Its Predictors Among Obstetric Health Care Providers Working at Public Referral Hospitals in the Oromia Region of Ethiopia in 2022: Cross-Sectional Questionnaire Study.

A partograph is a pictorial representation of the relationship between cervical dilatation and the time used to diagnose prolonged and obstructed labor. However, the utilization of paper-based partograph is low and it is prone to documentation errors, which can be avoided with the use of electronic partographs. There is only limited information on the proportion of intention to use mobile-based partographs and its predictors. The objective of this study was to determine the proportion of obstetric health care providers at public referral hospitals in Oromia, Ethiopia, in 2022 who had the intention to use mobile-based partographs and to determine the predictors of their intention to use mobile-based partographs. We performed an institution-based cross-sectional study from June 1 to July 1, 2022. Census was conducted on 649 participants. A self-administered structured English questionnaire was used, and a 5% pretest was performed. Data were entered into EpiData version 4.6 and exported to SPSS version 25 for descriptive analysis and AMOS (analysis of moment structure; version 23) for structural and measurement model assessment. Descriptive and structural equation modeling analyses were performed. The hypotheses developed based on a modified Technology Acceptance Model were tested using path coefficients and P values <.05. About 65.7% (414/630; 95% CI 61.9%-69.4%) of the participants intended to use mobile-based electronic partographs, with a 97% (630/649) response rate. Perceived usefulness had a positive influence on intention to use (β=.184; P=.02) and attitude (β=.521; P=.002). Perceived ease of use had a positive influence on attitude (β=.382; P=.003), perceived usefulness (β=.503; P=.002), and intention to use (β=.369; P=.001). Job relevance had a positive influence on perceived usefulness (β=.408; P=.001) and intention to use (β=.185; P=.008). Attitude positively influenced intention to use (β=.309; P=.002). Subjective norms did not have a significant influence on perceived usefulness (β=.020; P=.61) and intention to use (β=-.066; P=.07). Two-thirds of the obstetric health care providers in our study intended to use mobile-based partographs. Perceived usefulness, perceived ease of use, job relevance, and attitude positively and significantly influenced their intention to use mobile-based electronic partographs. The development of a user-friendly mobile-based partograph that meets job and user expectations can enhance the intention to use.

Transvaginal Ultrasound Versus Bishop Score in Predicting Labour Dystocia at Full-Term Nullipara Undergoing Labour Induction.

Precise assessment of cervical conditions before labor induction is crucial for predicting the success of normal vaginal delivery. The cervix primary condition has a significant value in determining the succession of induction of labour. Traditionally, assessment of cervix before induction has been based on a cervix digital examination using Bishop's scoring method.This study compares transvaginal ultrasonographic (TVS) cervical assessment with the traditional Bishop score in nulliparous women undergoing labor induction, aiming to evaluate their predictive abilities for labor dystocia. In a prospective observational study of 200 pregnant women at Al Hussein University Hospital between October 2022 and July 2023, cervical length, funneling, and posterior cervical angle were measured using transvaginal ultrasound. The Bishop score was recorded before induction. Statistical analyses, including Student's "t"-test and ROC curve, were conducted using SPSS. 68% delivered via normal vaginal delivery (NVD) and 32% via cesarean section (CS). The NVD group exhibited significantly higher Bishop scores (6.82±1.36 vs 3.70±0.94), lower cervical length (25.46±3.99 vs 37.34±2.09), and higher cervical angle (121.39±5.70 vs 89.01±6.09), than the CS group. ROC curve analysis revealed that a Bishop score ≥4.5 had 89% sensitivity and 87.5% specificity, a cervical angle ≥ 92.5 had 98.5% sensitivity and 95.3% specificity, and a cervical length ≥31.5 had 96.9% sensitivity and 97.1% specificity for predicting NVD. The posterior cervical angle, alongside cervical length, proves to be a more sensitive indicator for predicting labor dystocia during induction compared to the traditional Bishop score.
