Ability of an obstetric hemorrhage risk assessment tool to predict quantitative peripartum blood loss.

OBJECTIVES: Hemorrhage risk assessment tools have been studied using estimated blood loss. We study the association between peripartum hemorrhage risk assessment score and peripartum quantified blood loss (QBL) in term vaginal and cesarean deliveries. METHODS: This is a retrospective analysis conducted on 3,657 patients who underwent term vaginal and cesarean deliveries at a public hospital in New York City. Utilizing the risk assessment tool developed by the Association of Women's Health, Obstetric and Neonatal Nurses (AWHONN), patients were categorized into low-, medium-, or high-risk groups for postpartum hemorrhage. RESULTS: Medium-risk (B=0.08, SE=0.01, p<0.001) and high-risk (B=0.12, SE=0.02, p<0.001) AWHONN scores were associated with significantly higher QBL as compared to low-risk AWHONN score. Medium-risk approached significance (OR: 1.67, 95 % CI: 1.00, 2.79, p=0.050) and high-risk AWHONN score was significantly associated (OR: 1.95, 95 % CI: 1.09, 3.48, p=0.02) with increased odds for postpartum hemorrhage (≥1,000 mL). Each individual factor comprising the AWHONN score whose percentage in our sample was seen in greater than 2.7 % of patients was independently significantly associated with increased QBL (six of nine factors) and postpartum hemorrhage (four of nine factors). CONCLUSIONS: The AWHONN measure previously validated with estimated blood loss predicted obstetric blood loss with QBL. Although not on the basis of the data shown in our study, we believe that QBL should be routinely used to measure obstetric blood loss.

Clinical implications of a Couvelaire uterus with placental abruption: A retrospective study.

OBJECTIVE: This study aimed to clarify the maternal and neonatal outcomes based on the presence or absence of a Couvelaire uterus with placental abruption. METHODS: This single-center retrospective study was conducted at a tertiary perinatal center in Japan, including patients diagnosed with acute placental abruption who delivered live births via cesarean section between 2016 and 2023. Patients were divided into two groups based on the presence or absence of a Couvelaire uterus during surgery: the Couvelaire and normal uterus groups. Maternal and neonatal outcomes were assessed. RESULTS: This study included 76 patients: 24 in the Couvelaire group and 52 in the normal uterus group. No patients underwent hysterectomies. The Couvelaire group had significantly higher intraoperative blood loss (median 1152 vs 948 g, P = 0.010), blood transfusion rates (58% vs 31%, P = 0.022), fibrinogen administration rates (38% vs 13%, P = 0.038), intensive care unit/high care unit admission rates (29% vs 7.7%, P = 0.013), and disseminated intravascular coagulation complication rates (25% vs 7.7%, P = 0.038). There were no differences in birth weight, gestational age (median 2387 vs 2065 g, P = 0.082), Apgar score <4 at 5 min (4.2% vs 3.9%, P = 0.95), umbilical artery blood pH <7.1 (25% vs 22%, P = 0.82), and neonatal death (4.2% vs 1.9%, P = 0.57). CONCLUSION: A Couvelaire uterus indicated adverse maternal outcomes but not neonatal ones. Its presence necessitates preparation for blood transfusions and/or intensive patient follow-up.

Tranexamic acid versus oxytocin prophylaxis in reducing post-partum blood loss, in low-risk pregnant women: TRANOXY STUDY, a phase III randomized clinical trial.

Background: To assess the equivalence of tranexamic acid (TRAN) versus synthetic oxytocin (OXY) in reducing post-partum blood loss, in full-term patients (37-42 weeks), at low risk of post-partum hemorrhage, with vaginal childbirth. Methods: Phase III, randomized (1:1), open-label, longitudinal, multi-center, prospective clinical trial (Prot. n 63209, ClinicalTrials.gov Identifier: NCT02775773). From January 7, 2020, to June 30, 2023, a total of 256 women were enrolled at two general urban community hospitals in Italy, serving a multi-ethnic patient population with National Health Insurance. The primary outcome was to explore a potential equivalence between the two treatments (OXY and TRAN) in preventing total blood loss. Therefore, we randomized 231 women into two groups: Group A (OXY), 127 women who were administered 10UI intramuscularly within 5 min from childbirth; Group B (TRAN), 104 women to whom 1-g slow intravenous infusion was administered within 5 min from childbirth. Findings: At the time of delivery, mean blood loss for OXY group versus TRAN group was 269.12 mL versus 263.88 mL, respectively, with equivalence between the two groups. Similarly, there was equivalence in total blood loss between the OXY and the TRAN group (397.66 mL versus 405.64 mL, respectively. No statistical differences between Hb levels at admission and discharge in the two groups were reported. No difference was found in terms of additional uterotonic and surgical therapies between the two groups of patients. Neither group showed thrombotic complications at check-up performed after 7 days or after a questionnaire regarding adverse effects, subjected after 40 days. Interpretation: The study shows the equivalence of tranexamic acid versus synthetic oxytocin in post-partum blood loss prophylaxis in term patients at low risk of PPH with vaginal childbirth. The safety profiles of OXY and TRAN were similar. Funding: None.

Spatiotemporal Characteristics and Risk Factors for All and Severity-Specific Preterm Births in Southern China, 2014-2021: Large Population-Based Study.

BACKGROUND: The worldwide incidence of preterm births is increasing, and the risks of adverse outcomes for preterm infants significantly increase with shorter gestation, resulting in a substantial socioeconomic burden. Limited epidemiological studies have been conducted in China regarding the incidence and spatiotemporal trends of preterm births. Seasonal variations in risk indicate the presence of possible modifiable factors. Gender influences the risk of preterm birth. OBJECTIVE: This study aims to assess the incidence rates of preterm birth, very preterm birth, and extremely preterm birth; elucidate their spatiotemporal distribution; and investigate the risk factors associated with preterm birth. METHODS: We obtained data from the Guangdong Provincial Maternal and Child Health Information System, spanning from January 1, 2014, to December 31, 2021, pertaining to neonates with gestational ages ranging from 24 weeks to 42 weeks. The primary outcome measures assessed variations in the rates of different preterm birth subtypes over the course of the study, such as by year, region, and season. Furthermore, we examined the relationship between preterm birth incidence and per capita gross domestic product (GDP), simultaneously analyzing the contributing risk factors. RESULTS: The analysis incorporated data from 13,256,743 live births. We identified 754,268 preterm infants and 12,502,475 full-term infants. The incidences of preterm birth, very preterm birth, and extremely preterm birth were 5.69 per 100 births, 4.46 per 1000 births, and 4.83 per 10,000 births, respectively. The overall incidence of preterm birth increased from 5.12% in 2014 to 6.38% in 2021. The incidence of extremely preterm birth increased from 4.10 per 10,000 births in 2014 to 8.09 per 10,000 births in 2021. There was a positive correlation between the incidence of preterm infants and GDP per capita. In more developed economic regions, the incidence of preterm births was higher. Furthermore, adjusted odds ratios revealed that advanced maternal age, multiple pregnancies, and male infants were associated with an increased risk of preterm birth, whereas childbirth in the autumn season was associated with a protective effect against preterm birth. CONCLUSIONS: The incidence of preterm birth in southern China exhibited an upward trend, closely linked to enhancements in the care capabilities for high-risk pregnant women and critically ill newborns. With the recent relaxation of China's 3-child policy, coupled with a temporary surge in advanced maternal age and multiple pregnancies, the risk of preterm birth has risen. Consequently, there is a pressing need to augment public health investments aimed at mitigating the risk factors associated with preterm birth, thereby alleviating the socioeconomic burden it imposes.

Video analysis of real-life shoulder dystocia to assess technical and non-technical performance.

INTRODUCTION: Managing obstetric shoulder dystocia requires swift action using correct maneuvers. However, knowledge of obstetric teams' performance during management of real-life shoulder dystocia is limited, and the impact of non-technical skills has not been adequately evaluated. We aimed to analyze videos of teams managing real-life shoulder dystocia to identify clinical challenges associated with correct management and particular non-technical skills correlated with high technical performance. MATERIAL AND METHODS: We included 17 videos depicting teams managing shoulder dystocia in two Danish delivery wards, where deliveries were initially handled by midwives, and consultants were available for complications. Delivery rooms contained two or three cameras activated by Bluetooth upon obstetrician entry. Videos were captured 5 min before and after activation. Two obstetricians assessed the videos; technical performances were scored as low (0-59), average (60-84), or high (85-100). Two other assessors evaluated non-technical skills using the Global Assessment of Team Performance checklist, scoring 6 (poor) to 30 (excellent). We used a spline regression model to explore associations between these two score sets. Inter-rater agreement was assessed using interclass correlation coefficients. RESULTS: Interclass correlation coefficients were 0.71 (95% confidence interval 0.23-0.89) and 0.82 (95% confidence interval 0.52-0.94) for clinical and non-technical performances, respectively. Two teams had low technical performance scores; four teams achieved high scores. Teams adhered well to guidelines, demonstrating limited head traction, McRoberts maneuver, and internal rotation maneuvers. Several clinical skills posed challenges, notably recognizing shoulder impaction, applying suprapubic pressure, and discouraging women from pushing. Two non-technical skills were associated with high technical performance: effective patient communication, with teams calming the mother and guiding her collaboration during internal rotational maneuvers, and situation awareness, where teams promptly mobilized all essential personnel (senior midwife, consultant, pediatric team). Team communication, stress management, and task management skills were not associated with high technical performance. CONCLUSIONS: Videos capturing teams managing real-life shoulder dystocia are an effective tool to reveal challenges with certain technical and non-technical skills. Teams with high technical performance are associated with effective patient communication and situational awareness. Future training should include technical skills and non-technical skills, patient communication, and situation awareness.

Gambian Mothers Lack Obstetric Danger Sign Knowledge, But Educational Intervention Shows Promise.

Background: The Gambia has the 12th highest maternal mortality rate in the world, with 80% of deaths resulting from avoidable causes. Unawareness of pregnancy danger signs (DS) has been shown to be a barrier to seeking obstetric care, while app-based education intervention has shown promise. Objective: We aim to assess patient awareness of DS, identify barriers to awareness, and evaluate potential for implementing smartphone-based technologies for education. Methods: A cross-sectional semi-structured survey was administered to Gambian women (n = 100) across five hospitals/health centers. Data and informed consent were collected via an online survey portal. Analysis included bivariate analysis and descriptive statistics with p < 0.05 significance level. Recall of 0-2 DS per category was classified as "low" knowledge, 3-5 as "moderate" knowledge, and 6+ as "sufficient" knowledge. Cross-category recall was quantified for overall awareness level (0-6 = "low", 7-12 = "moderate", 13+ = "sufficient". N = 28 total DS). Findings: Although 75% of participants (n = 100) self-perceived "sufficient" knowledge of DS, the average recall was only two (SD = 2, n = 11) pregnancy DS, one labor and delivery DS (SD = 1, n = 8), and one postpartum DS (SD = 1, n = 9). Twenty-one women were unable to recall any danger signs. "Low" awareness was identified in 77% of women, while 23%, and 0% of women showed "moderate" and "sufficient" overall awareness, respectively. Education level was significantly correlated with overall danger sign recall (ρ(98) = .243, p = .015) and awareness level (ρ(98) = .265, p = .008). Monthly income was significantly correlated with awareness level (ρ(97) = .311, p = .002). Smartphone ownership was reported by 76% of women, and 97% expressed interest in using app-based video (94%) or provider (93%) teaching. Conclusions: Women had low knowledge of obstetric danger signs, and true awareness of danger signs was remarkably lower than self-perceived knowledge. However, patients exhibited proper healthcare-seeking behavior when danger signs arose. Findings suggest that video- or messaging-based education from local healthcare providers may be effective DS educational interventions.

Childbirth experiences of women with a history of physical, sexual, and child abuse: a cross-sectional study of 2,575 Russian women.

BACKGROUND: A substantial number of women who subsequently become pregnant and give birth have a history of physical, sexual, and/or child abuse. This study investigated the associations of these types of traumas and their cumulative effect with childbirth experiences, namely, mode of birth, maternal and child complications during pregnancy/childbirth, preterm birth, medical procedures, and obstetric violence during labour. METHODS: A group of Russian women (n = 2,575) who gave birth within the previous 12 months, completed a web-based survey, where they provided demographic information, details about their childbirth experiences, and a history of trauma. RESULTS: Women with any type of past abuse were at higher risk for maternal complications during pregnancy/childbirth (exp(ß) < 0.73, p < 0.010 for all). More specific to the type of trauma were associations of physical abuse with caesarean birth, child abuse with complications during pregnancy/childbirth for the baby, and physical and child abuse with obstetric violence (exp(ß) < 0.54, p < 0.022 for all). There was a cumulative effect of trauma for all the outcomes except for medical procedures during childbirth and preterm birth. CONCLUSION: This study provides insights into potential different individual effects of physical, sexual, and/or child abuse as well as their cumulative impact on the childbirth experiences. The robust findings about maternal complications during pregnancy/childbirth and obstetric violence highlight the importance of trauma-informed care, supportive policies, and interventions to create safe and empowering birthing environments that prioritise patient autonomy, dignity, and respectful communication.

The Use of Evening Primrose Oil for Cervical Ripening in Low-Risk Women with Term Pregnancy: A Randomized Double-Blinded Controlled Trial.

BACKGROUND: Several methods have been developed for cervical ripening. The data regarding the efficiency of evening primrose oil (EPO) are inconsistent. The purpose of this study was to investigate the outcomes of EPO use on cervical ripening in low-risk women with term pregnancy. PATIENTS AND METHODS: Low-risk term pregnant women referred to the obstetrics clinic of Imam Hossein Hospital in Tehran who were eligible according to the inclusion were randomized either to the case or control group. The case group received 1,000 mg vaginal EPO capsule, and the other group received a vaginal placebo capsule daily, similar to the original drug. The primary outcome was Bishop score, while the duration of labor phases and the inducing procedures were the secondary outcomes. RESULTS: Forty-eight participants were randomized to each group and were considered for data analysis. Although Bishop score was not statistically different before the intervention, it was significantly higher in case group compared to the placebo group after the intervention (EPO = 5.83 ± 1.68, placebo = 5.19 ± 1.52, p value = 0.002). Four participants in the case group and two in the control group underwent cesarean section (p value = 0.677). The need for labor induction was significantly higher in the placebo group than EPO group (oxytocin injection: 10.4% vs. 31.3%, p value = 0.012, amniotomy: 75% vs. 41.7, p value = 0.001). CONCLUSION: The vaginal use of EPO could be considered as a safe and efficient approach for cervical ripening in low-risk term pregnant women.Es wurden verschiedene Methoden zur Zervixreifung entwickelt. Die Daten zur Wirksamkeit von Nachtkerzenöl (evening primrose oil, EPO) sind uneinheitlich. Mit dieser Studie sollen die Ergebnisse der Anwendung von EPO zur Zervixreifung bei Frauen mit niedrigem Risiko und termingerechter Schwangerschaft untersucht werden.Schwangere Frauen mit niedrigem Risiko und termingerechter Schwangerschaft, die in die Geburtsklinik des Imam-Hossein-Krankenhauses in Teheran eingewiesen wurden und gemäss den Einschlusskriterien für die Teilnahme infrage kamen, wurden randomisiert der Fall- oder der Kontrollgruppe zugewiesen. Die Fallgruppe erhielt 1.000 mg EPO als Vaginalkapseln, während die andere Gruppe täglich eine vaginale Placebokapsel erhielt, die dem Originalpräparat ähnelte. Primäres Zielkriterium war der Bishop-Score und sekundäre Zielkriterien waren die Dauer der Wehenphasen sowie die Verfahren zur Geburtseinleitung.Jeder Gruppe wurden randomisiert 48 Teilnehmerinnen zugewiesen und bei der Datenanalyse berücksichtigt. Während vor der Intervention kein statistisch signifikanter Unterschied im Bishop-Score bestand, fiel dieser nach der Intervention in der Fallgruppe signifikant höher aus als in der Placebogruppe (EPO = 5,83 ± 1,68, Placebo = 5,19 ± 1,52, p-Wert = 0,002). Bei vier Teilnehmerinnen in der Fallgruppe und zwei in der Kontrollgruppe wurde ein Kaiserschnitt durchgeführt (p-Wert = 0,677). Die Notwendigkeit einer Weheneinleitung war in der Placebogruppe signifikant höher als in der EPO-Gruppe (Oxytocin-Injektion: 10,4% vs. 31,3%, p-Wert = 0,012, Amniotomie: 75% vs. 41,7%, p-Wert = 0,001).Die vaginale Anwendung von EPO kann als sicherer und wirksamer Ansatz zur Zervixreifung bei Frauen mit niedrigem Risiko und termingerechter Schwangerschaft angesehen werden.

Scoping Review of Fall Risk Assessment Tools for Women Who Receive Maternity Care.

OBJECTIVE: To identify and describe fall risk assessment tools used for women who receive maternity care. DATA SOURCES: PubMed, CINAHL Complete, MEDLINE Complete, Cochrane Library, Scopus, SciELO, and Repositórios Científicos de Acesso Aberto de Portugal (RCAAP). STUDY SELECTION: We considered reports published until November 28, 2022, that included women during pregnancy, childbirth, or the postpartum period; involved the use of fall risk assessment tools, regardless of context; and were published in English, French, Portuguese, or Spanish. DATA EXTRACTION: We extracted the following data from the included reports: author(s)/year/country, aim/sample, research design/type of report, tool (i.e., the fall risk assessment tool used), findings, reliability, and validity. DATA SYNTHESIS: We found 13 reports in which the authors addressed nine fall risk assessment tools. Seven of these tools were applied during pregnancy (Kyle's tool, Pregnant Women Information Form and Assessment Scale for Risk of Falling in Pregnant Women, Obstetric Fall Risk Assessment System), labor (Obstetric Fall Risk Assessment System), the postpartum period (Cooksey-Post Obstetric Delivery Fall Risk Assessment, Kyle's tool, Risk of Falling in Post-partum Women (SLOPE), Obstetric Fall Risk Assessment System, Post-epidural Fall Risk Assessment Score, and Maternal Fall Risk Assessment Scale). The Dionne's Egress Test and the Motor Strength Scale do not address the characteristics of the women who receive maternity care. Psychometric characteristics were available for the Pregnant Women Information Form and Assessment Scale for Risk of Falling in Pregnant Women, Post-epidural Fall Risk Assessment Score, Maternal Fall Risk Assessment Scale, and Risk of Falling in Post-partum Women. CONCLUSION: Some fall risk assessment tools are used to assess women who receive maternity care without proper validation in this specific population. The use of fall risk assessment tools that are validated for women who receive maternity care may help nurses make clinical judgments when assessing fall risk and implement measures for fall prevention.

Influence of different volumes and frequency of programmed intermittent epidural bolus in labor on maternal and neonatal outcomes: A systematic review and network meta-analysis.

STUDY OBJECTIVE: In labor, programmed intermittent epidural bolus (PIEB) can be defined as the bolus administration of epidural solution at scheduled time intervals. Compared to continuous epidural infusion (CEI) with or without patient controlled epidural analgesia (PCEA), PIEB has been associated with decreased pain scores and need for rescue analgesia and increased maternal satisfaction. The optimal volume and dosing interval of PIEB, however, has still not been determined. DESIGN: Systematic review and network meta-analysis registered with PROSPERO (CRD42022362708). SETTINGS: Labor. PATIENTS: Pregnant patients. INTERVENTIONS: Central, CINAHL, Global Health, Ovid Embase, Ovid Medline and Web of Science were searched for randomized controlled trials that examined pregnant patients in labor who received CEI or PIEB with or without a PCEA component. Network meta-analysis was performed with a frequentist method, facilitating the indirect comparison of PIEB with different volumes and dosing intervals through the common comparator of CEI and substituting or supplementing direct comparisons with these indirect ones. Continuous and dichotomous outcomes were presented as mean differences and odds ratios, respectively, with 95% confidence intervals. The risk of bias was evaluated using the Cochrane risk of bias 2 tool. MAIN RESULTS: Overall, 30 trials were included. For the first primary endpoint, need for rescue analgesia, PIEB delivered at a volume of 4 ml and frequency of 45 min (4/45) was inferior to PIEB 8/45 (OR 3.55; 95% CI 1.12-11.33), PIEB 10/60 was superior to PIEB 2.5/15 (OR 0.36; 95% CI 0.16-0.82), PIEB 4/45 (OR 0.14; 95% CI 0.03-0.71) and PIEB 5/60 (OR 0.23; 95% CI 0.08-0.70), and PIEB 5/30 was not inferior to PIEB 10/60 (OR 0.61; 95% CI 0.31-1.19). For the second primary endpoint, maternal satisfaction, no differences were present between the various PIEB regimens. The quality of evidence for these multiple primary endpoints was low owing to the presence of serious limitations and imprecision. Importantly, PIEB 5/30 decreased the pain score at 4 h compared to PIEB 2.5/15 (MD 2.45; 95% CI 0.13-4.76), PIEB 5/60 (MD -2.28; 95% CI -4.18--0.38) and PIEB 10/60 (MD 1.73; 95% CI 0.31-3.16). Mean ranking of interventions demonstrated PIEB 10/60 followed by PIEB 5/30 to be best placed to reduce the cumulative dose of local anesthetic, and this resulted in an improved incidence of lower limb motor blockade for PIEB 10/60 in comparison to CEI (OR 0.30; 95% CI 0.14-0.67). No differences in neonatal outcomes were found. Some concerns were present for the risk of bias in two thirds of trials and the risk of bias was shown to be high in the remaining one third of trials. CONCLUSIONS: Future research should focus on PIEB 5/30 and PIEB 10/60 and how the method of analgesia initiation, nature and concentration of local anesthetic, design of epidural catheter and rate of administration might influence outcomes related to the mother and neonate.

Relations between maternal height, shoe size, and the success of vaginal delivery in birth weight over 4000 g.

OBJECTIVE: Macrosomia is associated with increased risk of fetal and maternal complications such as trauma during birth, cesarean delivery, postpartum hemorrhage, and shoulder dystocia. Sonographic estimation of fetal weight is imprecise particularly in excessively large fetuses, prompting the need for additional measures to assess the feasibility of vaginal delivery of a macrosomic newborn and thus improve prenatal consultation. MATERIALS AND METHODS: This retrospective case-control study included women who delivered a singleton macrosomic newborn (birth weight>4,000 g), either vaginally (N = 762) or by urgent cesarean delivery during labor (N = 109). Using multivariable analysis, we examined correlations of maternal height≥170 cm and shoe size≥40 with successful vaginal delivery. RESULTS: Women who delivered vaginally had lower mean intrapartum BMI (p < 0.001) and lower rate of gestational diabetes (p = 0.003). Women with a shoe size≥40 were 2.2 times more likely to give birth vaginally. Cesarean section rate was 5.9 % among women with height≥170 cm and shoe size≥40; and 16.5 % among women with height<170 cm and shoe size<40. Multivariable analysis, adjusted for gestational diabetes, parity, and BMI, revealed that shoe size≥40 and maternal height≥170 cm correlated with success in vaginal delivery, OR = 3.1 (95%CI 1.3-7.3, p = 0.009). CONCLUSION: Shoe size and maternal height may help predict success of vaginal birth of the macrosomic newborns.

Factores de riesgo relacionados con las complicaciones de la hemorragia obstétrica

Introducción: La hemorragia obstétrica es considerada una causa mayor de mortalidad materna. El reconocimiento de las mujeres con riesgo de desarrollar complicaciones durante la hemorragia obstétrica, es la primera acción para promover un tratamiento optimizado y evitar la muerte. Objetivo: Identificar los factores de riesgo de complicaciones en pacientes con hemorragia obstétrica. Métodos: Estudio observacional, analítico de casos y controles, con 12 casos (con complicaciones) y 24 controles (sin complicaciones). Se aplicó las medidas resúmenes para cada tipo de variables y la determinación de los factores de riesgos mediante la aplicación del odds ratio (OR), se utilizó el paquete estadístico SPSS versión 26.0, con un intervalo de confianza (IC) del 95 %. Resultados: La combinación del choque hipovolémico, más la insuficiencia renal aguda, fue la complicación más frecuente para un 13,8 %. Predominó la atonía uterina para un 50,0 % como causa de hemorragia. Las variables predictivas de complicaciones fueron: el valor de creatinina ≥ 113 µmol/L (OR= 19,08; IC: 2,75-138,36), índice internacional normalizado ≥ 2 (OR= 4,66; IC: 1,46-14,90), hematocrito < 0,23 (OR= 4,00; IC: 1,76-9,08) y hemoglobina < 70 g/L (OR= 2,22; IC: 1,25-3,95). Conclusiones: La creatinina ≥ 113 µmol/L, índice internacional normalizado ≥ 2, hematocrito < 0,23 y hemoglobina < 70 g/L son los principales factores de riesgo identificados para el desarrollo de complicaciones durante la hemorragia obstétrica.

Introduction: Obstetric hemorrhage is considered a major cause of maternal mortality. Recognition of women at risk of developing complications during obstetric hemorrhage is the first action to promote optimized treatment and avoid death. Objective: Identify risk factors for complications in patients with obstetric hemorrhage. Methods: Observational, analytical case-control study, with 12 cases (with complications) and 24 controls (without complications). The summary measures were applied for each type of variables and the determination of the risk factors by applying the odds ratio (OR), the SPSS statistical package version 26.0 was used, with a confidence interval (CI) of 95%. Results: The combination of hypovolemic shock, plus acute renal failure, was the most frequent complication for 13.8%. Uterine atony predominated for 50.0% as the cause of hemorrhage. The predictive variables of complications were: creatinine value ≥ 113 µmol/L (OR= 19.08; CI: 2.75-138.36), international normalized ratio ≥ 2 (OR= 4.66; CI: 1. 46-14.90), hematocrit < 0.23 (OR= 4.00; CI: 1.76-9.08) and hemoglobin < 70 g/L (OR= 2.22; CI: 1.25-3.95). Conclusions: Creatinine ≥ 113 µmol/L, international normalized ratio ≥ 2, hematocrit < 0.23 and hemoglobin < 70 g/L are the main risk factors identified for the development of complications during obstetric hemorrhage.

Perinatal Outcome in Overweight Women: An Audit.

BACKGROUND: Obesity in pregnancy is associated with a myriad of well-documented complications. However, the outcomes of pregnancy in overweight females, who are not classified as obese, have not been studied. The aim of the study was to assess foeto-maternal outcomes in primigravida who are overweight and compare them to normal-weight patients. MATERIAL AND METHODS: This was a prospective observational cohort study and included primigravida with full-term gestation (between 38 and 42 weeks), with a single live foetus in vertex presentation, who were admitted for labour induction. Based on pre-pregnancy weight, patients were divided into normal weight (body mass index, BMI<23kg/m2) and overweight (BMI≥23kg/m2 and<25kg/m2) categories labelled as groups A and B, respectively. Data was collected for gestational age, demographics (age, education, occupation), and obstetric and labour-related parameters per pre-designed proforma. Parameters included were the reason for induction, number of doses of prostaglandin E2 (PGE2) gel used, duration of labour, induction to delivery interval, and mode of birth- operative/ non-operative. Data was also collected for peri-partum maternal complications, neonatal Apgar score, and need for Neonatal Intensive Care Unit (NICU) admissions. RESULTS: One hundred and fifty patients were recruited in the study and divided based on weight into two groups- 115 in Group A (normal weight) and 35 in Group B (overweight). Compared to Group A, a higher proportion of patients in Group B needed a third dose of PGE2 gel (n=24, 20.8% vs n=18, 51.4%). Also, more patients in Group B had an induction to delivery time of longer than 30 hours (n=7, 20% vs n=5, 4.3%) and had a higher incidence of failed induction needing caesarean section (n=9, 25.7% vs n=13, 11.3%). Neonates born to overweight mothers had a poor Apgar score at 1 min. However, on reassessment, Apgar improved at 5 minutes, and no statistically significant difference was seen for admission to NICU- 5.7% (n=2) in Group B vs 1.7% (n=2) in Group A Conclusion: Pregnancy in overweight females is associated with prolonged labour, higher instances of failed induction, and poor neonatal outcomes at initial assessment. Thus, perinatal counselling and management should focus on weight control while also planning appropriate strategies for monitoring and treating pregnancy-related complications if weight control measures fail. Although obesity is the main focus of research, we suggest including overweight but non-obese females in such studies as they have similar adverse outcomes and complications.

Sociodemographic determinants and mortality of premature newborns in a medium and low-income population in Colombia, 2017-2019. / Factores determinantes sociodemográficos y de mortalidad en recién nacidos prematuros en población de medianos y bajos ingresos en Colombia, 2017-2019

Introduction: The birth of premature babies is a public health problem with a high impact on infant morbidity and mortality. About 40% of mortality in children under five years occurs in the first month of life. Objective: To identify the association between maternal sociodemographic factors, premature birth, and mortality in newborns under 37 weeks in Santiago de Cali, 2017-2019. Materials and methods: We conducted a descriptive, cross-sectional study. We evaluated the records of Cali's Municipal Public Health Office. We calculated the crude and adjusted odd ratios and confidence intervals (95%) using the logistic regression model, data processing in Stata 16, and georeferencing the cases in the QGIS software. Results: From 2017 to 2019, premature babies in Cali corresponded to 11% of births. Poor prenatal care increased 3.13 times the risk of being born before 32 weeks (adjusted OR = 3.13; 95% CI = 2.75 - 3.56) and 1.27 times among mothers from outside the city (adjusted OR = 1.27; 95% CI = 1.15-1.41). Mortality was 4.29 per 1,000 live births. The mortality risk in newborns weighing less than 1,000 g increased 3.42 times (OR = 3.42; 95% CI = 2.85-4.12), delivery by cesarean section in 1.46 (OR = 1.46; CI 95% = 1.14-1.87) and an Apgar score - five minutes after birth- lower than seven in 1.55 times (OR = 1.55; CI 95% = 1.23-1.96). Conclusions: We found that less than three prenatal controls, mothers living outside Cali, afro-ethnicity, and cesarean birth were associated with prematurity of less than 32 weeks. We obtained higher mortality in newborns weighing less than 1,000 g.

Cultural Adaptation, Validation and Evaluation of the Psychometric Properties of an Obstetric Violence Scale in the Spanish Context.

Obstetric violence refers to dehumanized or derogative treatment of women in their pregnancy, childbirth or postpartum periods and may be manifested in different ways. Currently, there is no tool validated in Spain to measure women's perception of obstetric violence. The objective of this study was to carry out the cultural adaptation and validation of an existing 14-item obstetric violence scale in the Spanish context and to evaluate its psychometric properties. The research was conducted in two phases: first, a methodological study designed to evaluate content validity, through assessments by eight experts (calculating the Aiken V coefficient) and face validity in a sample of 20 women; second, a cross-sectional study to evaluate construct validity (through confirmatory factor analysis and Rasch analysis), divergent validity against a scale of birth satisfaction, known-groups validity and, finally, reliability. In Phase 1, Aiken V values higher than 0.71 were obtained for all items. Phase 2 was conducted on a sample of 256 women and the fit values for the unidimensional model were RMSEA: 0.070 (95% CI: 0.059-0.105) and GFI: 0.982 (95% CI: 0.823-0.990). The Rasch analysis indicated poor performance of item 2, which was removed. The Omega and Cronbach's Alpha coefficients were 0.863 and 0.860, respectively. A final 13-item version of the Obstetric Violence Scale was produced, with a total score ranging from 0 (no obstetric violence perception) to 52 (maximum obstetric violence perception). The Obstetric Violence Scale is a reliable and useful tool to measure women's perception of obstetric violence. This study was not registered.

Does a preterm labor-assessment algorithm improve preterm labor-related knowledge, clinical practice confidence, and educational satisfaction?: a quasi-experimental study.

PURPOSE: Preterm birth is increasing, and obstetric nurses should have the competency to provide timely care. Therefore, training is necessary in the maternal nursing practicum. This study aimed to investigate the effects of practice education using a preterm-labor assessment algorithm on preterm labor-related knowledge and clinical practice confidence in senior nursing students. METHODS: A pre-post quasi-experimental design with three groups was used for 61 students. The preterm-labor assessment algorithm was modified into three modules from the preterm-labor assessment algorithm by March of Dimes. We evaluated preterm labor-related knowledge, clinical practice confidence, and educational satisfaction. Data were analyzed with the paired t-test and repeated-measures analysis of variance. RESULTS: The practice education using a preterm-labor assessment algorithm significantly improved both preterm labor-related knowledge and clinical practice confidence (paired t=-7.17, p<.001; paired t=-5.51, p<.001, respectively). The effects of the practice education using a preterm-labor assessment algorithm on knowledge lasted until 8 weeks but decreased significantly at 11 and 13 weeks after the program, while the clinical practice confidence significantly decreased at 8 weeks post-program. CONCLUSION: The practice education using a preterm-labor assessment algorithm was effective in improving preterm labor-related knowledge and clinical practice confidence. The findings suggest that follow-up education should be conducted at 8 weeks, or as soon as possible thereafter, to maintain knowledge and clinical confidence, and the effects should be evaluated.

Providing Emotional Support and Physical Comfort During a Time of Social Distancing: A Thematic Analysis of Doulas' Experiences During the Coronavirus Pandemic.

Doulas are trained, non-clinical professionals that provide a continuum of support for mothers. An interpretive phenomenological approach was used to explore the professional experiences of doulas (n = 17) during the COVID-19 pandemic in the US. Data were collected using brief intake surveys, in-depth semi-structured interviews, and an online discussion group. After a list of significant statements was created and grouped during emergent themes analysis, the reflections were summarized into three themes, (1) Doula Resilience, (2) Experiencing Vulnerability, and (3) Concern for Client Vulnerability that encapsulate the experiences of doulas during the COVID-19 pandemic. We conclude that as part of the COVID-19 recovery process, policy makers should look to non-clinical interventions for improving maternal health, such as promoting and supporting synergy between doulas and other maternal health service providers.

Long-term trends in the incidence and management of shoulder dystocia in a tertiary obstetric unit in Hong Kong.

INTRODUCTION: Because there have been changes in the management of macrosomic pregnancies and shoulder dystocia in the past decade, this study was conducted to compare the incidences of shoulder dystocia and perinatal outcomes between the periods of 2000-2009 and 2010-2019. METHODS: This retrospective study was conducted in a tertiary obstetric unit. All cases of shoulder dystocia were identified using the hospital's electronic database. The incidences, maternal and fetal characteristics, obstetric management methods, and perinatal outcomes were compared between the two study periods. RESULTS: The overall incidence of shoulder dystocia decreased from 0.23% (134/58 326) in 2000-2009 to 0.16% (108/65 683) in 2010-2019 (P=0.009), mainly because of the overall decline in the proportion of babies with macrosomia (from 3.3% to 2.3%; P<0.001). The improved success rates of the McRoberts' manoeuvre (from 31.3% to 47.2%; P=0.012) and posterior arm extraction (from 52.9% to 92.3%; P=0.042) allowed a greater proportion of affected babies to be delivered within 2 minutes (from 59.0% to 79.6%; P=0.003). These changes led to a significant reduction in the proportion of fetuses with low Apgar scores: <5 at 1 minute of life (from 13.4% to 5.6%; P=0.042) and <7 at 5 minutes of life (from 11.9% to 4.6%; P=0.045). CONCLUSION: More proactive management of macrosomic pregnancies and enhanced training in the acute management of shoulder dystocia led to significant improvements in shoulder dystocia incidence and perinatal outcomes from 2000-2009 to 2010-2019.

A comparison of neonatal outcomes after taking progesterone pills and progesterone intramuscular injections in preterm labor: An RCT.

Background: Approximately two-thirds of infant mortality within the first year of life are caused by preterm labor (PL). Objective: This study aimed to investigate the effects of progesterone-based compounds to prevent PL. Materials and Methods: This randomized clinical trial study was conducted on 146 pregnant women admitted to Department of Obstetrics and Gynecology, Afzalipour hospital in Kerman University of Medical Sciences, Kerman, Iran in June 2019. The participants with PL received Tocolytic and 12 mg Betamethasone in 2 doses over 2 days to mature the fetus's lungs. Stopping PL was considered a 12-hr period without any contractions after finishing the Tocolytic. Following the successful cessation of PL, the participants were monitored for 48 hr. Subsequently, the participants were divided into 2 groups. Participants received 200 mg Lutogel capsules orally per day in group A while group B received a weekly dose of 250 mg Proluton in the form of intramuscular injection, respectively. Treatment in groups continued until the 36th wk of delivery. The participants were followed-up weekly, and if any signs of PL were detected, an obstetrician carried out a vaginal examination. Results: The incidence of PL was the same in both groups. There was no significant difference in the latent phase, average birth weight, and the neonatal intensive care unit admission frequency (p = 0.07, 0.17, 0.58, respectively) between groups. Conclusion: No difference in the results obtained from theneonataloutcomes evaluated in groups. Both medications similarly led to recovering pregnancy and neonatal outcomes caused by PL. Applying the oral form with similar beneficial effects were pointed out in this study, which can be a solution to the issues caused by numerous injections that are inevitable in the injected administration of this medicine.

Sociodemographic determinants and mortality of premature newborns in a medium and low-income population in Colombia, 2017-2019 / Factores determinantes sociodemográficos y de mortalidad en recién nacidos prematuros en población de medianos y bajos ingresos en Colombia, 2017-2019

Introduction. The birth of premature babies is a public health problem with a high impact on infant morbidity and mortality. About 40% of mortality in children under five years occurs in the first month of life. Objective. To identify the association between maternal sociodemographic factors, premature birth, and mortality in newborns under 37 weeks in Santiago de Cali, 2017-2019. Materials and methods. We conducted a descriptive, cross-sectional study. We evaluated the records of Cali's Municipal Public Health Office. We calculated the crude and adjusted odd ratios and confidence intervals (95%) using the logistic regression model, data processing in Stata 16, and georeferencing the cases in the QGIS software. Results. From 2017 to 2019, premature babies in Cali corresponded to 11% of births. Poor prenatal care increased 3.13 times the risk of being born before 32 weeks (adjusted OR = 3.13; 95% CI = 2.75 - 3.56) and 1.27 times among mothers from outside the city (adjusted OR = 1.27; 95% CI = 1.15-1.41). Mortality was 4.29 per 1,000 live births. The mortality risk in newborns weighing less than 1,000 g increased 3.42 times (OR = 3.42; 95% CI = 2.85-4.12), delivery by cesarean section in 1.46 (OR = 1.46; CI 95% = 1.14-1.87) and an Apgar score - five minutes after birth- lower than seven in 1.55 times (OR = 1.55; CI 95% = 1.23-1.96). Conclusions. We found that less than three prenatal controls, mothers living outside Cali, afro-ethnicity, and cesarean birth were associated with prematurity of less than 32 weeks. We obtained higher mortality in newborns weighing less than 1,000 g.
