Intrapartum compromise

INTRODUCTION: Sufficient contractions are necessary for a successful delivery but each contraction temporarily constricts the oxygenated blood flow to the fetus. Individual fetal or placental characteristics determine how the fetus can withstand this temporary low oxygen saturation. However, only a few studies have examined the impact of uterine activity on neonatal outcome and even less attention has been paid to parturients' individual characteristics. Our objective was therefore to find out whether fetuses compromised by maternal or intrapartum risk factors are more vulnerable to excessive uterine activity...

Background : This systematic review aimed to clarify the association between the cerebroplacental ratio (CPR) and emergency cesarean sections (CSs) due to intrapartum fetal compromise (IFC). Methods : Datasets of PubMed, ScienceDirect, CENTRAL, Embase, and Google Scholar were searched for studies published up to January 2024 regarding the relationship between the CPR and the rate of CS for IFC, as well as the predictive value of the CPR. Results : The search identified 582 articles, of which 16 observational studies were finally included, most of them with a prospective design...

OBJECTIVE: Consent in ante-natal and birthing contexts is often challenging, controversial and poorly understood. Increasing evidence indicates that ethnic minority women's overall experiences of ante-natal care are unsatisfactory, but little is known about their involvement in the consent process. This study aims to explore the views and experiences of ethnic minority women when making decisions requiring their consent. DESIGN: Qualitative interview study SETTING: A national study conducted in the UK SAMPLE: Seventeen self-selecting ethnic minority women who had given birth in a UK hospital in the previous 12 months...

Childbirth is a defining moment in anyone's life, and it occurs 140 million times per year. Largely a physiologic process, parturition does come with risks; one mother dies every two minutes. These deaths occur mostly among healthy women, and many are considered preventable. For each death, 20 to 30 mothers experience complications that compromise their short- and long-term health. The risk of birth extends to the newborn, and, in 2020, 2.4 million neonates died, 25% in the first day of life. Hence, intrapartum care is an important priority for society...

BACKGROUND: The evidence-based management of human labor includes the antepartum identification of patients at risk for intrapartum hypoxia. However, available evidence has shown that most of the hypoxic-related complications occur among pregnancies classified at low-risk for intrapartum hypoxia, thus suggesting that the current strategy to identify the pregnancies at risk for intrapartum fetal hypoxia has limited accuracy. OBJECTIVE: To evaluate the role of the combined assessment of the cerebroplacental ratio (CPR) and uterine arteries (UtA) Doppler in the prediction of obstetric intervention (OI) for suspected intrapartum fetal compromise (IFC) within a cohort of low-risk singleton term pregnancies in early labor...

INTRODUCTION: Perinatal asphyxia, a condition that results from compromised placental or pulmonary gas exchange during the birth process, is rare but can lead to serious neonatal and long-term consequences. The visual analysis of cardiotocography (CTG) is designed to avoid perinatal asphyxia, but its interpretation can be difficult. Our aim was to test the impact of an e-learning training program for interpreting CTG on the rate of avoidable perinatal asphyxia at term. METHOD: We conducted a retrospective multicenter before-after study comparing two periods, before and after the implementation of e-learning training program from July 1, 2016 to December 31, 2016, in CTG interpretation for midwives and obstetricians in five maternity hospitals in the Paris area, France...

INTRODUCTION: Cerebroplacental ratio (CPR) has been shown to be an independent predictor of adverse perinatal outcome at term and a marker of failure to reach the growth potential (FRGP) regardless of fetal size, being abnormal in compromised fetuses with birthweight above the 10th centile. The main aim of this study was to propose a risk-based approach for the management of pregnancies with normal estimated fetal weight (EFW) and abnormal CPR near term. MATERIAL AND METHODS: This was a retrospective study of 943 pregnancies, that underwent an ultrasound evaluation of EFW and CPR at or beyond 34 weeks...

OBJECTIVE: To evaluate the capacity of fetal Doppler, maternal, and obstetric characteristics for the prediction of cesarean section due to intrapartum fetal compromise (IFC), a 5-min Apgar score < 7, and an adverse perinatal outcome (APO), in a high-risk population. MATERIALS AND METHODS: This was a prospective cohort study involving 613 singleton pregnant women, admitted for labor induction or at the beginning of spontaneous labor, who underwent Doppler ultrasound within the last 72 h before delivery...

INTRODUCTION: Fetuses with large lung lesions including congenital cystic adenomatoid malformations (CCAMs) are at risk for cardiopulmonary compromise. Prenatal maternal betamethasone and cyst drainage for micro- and macrocystic lesions respectively have improved outcomes yet some lesions remain large and require resection before birth (open fetal surgery, OFS), at delivery via an Ex Utero Intrapartum Treatment (EXIT), or immediately post cesarean section (section-to-resection, STR). We sought to compare prenatal characteristics and outcomes in fetuses undergoing OFS, EXIT, or STR to inform decision-making and prenatal counseling...

The measurement and analysis of fetal heart rate (FHR) and uterine contraction (UC) patterns, known as cardiotocography (CTG), is a key technology for detecting fetal compromise during labour. This technology is commonly used by clinicians to make decisions on the mode of delivery to minimise adverse outcomes. A range of computerised CTG analysis techniques have been proposed to overcome the limitations of manual clinician interpretation. While these automated techniques can potentially improve patient outcomes, their adoption into clinical practice remains limited...

Irritable bowel syndrome (IBS) is a prevalent functional gastrointestinal disorder worldwide. Extensive research has identified multiple factors contributing to its development, including genetic predisposition, chronic infection, gut dysbiosis, aberrant serotonin metabolism, and brain dysfunction. Recent studies have emphasized the critical role of the early life stage as a susceptibility window for IBS. Current evidence suggests that diet can heighten the risk of IBS in offspring by influencing the microbiota composition, intestinal epithelium structure, gene expression, and brain-gut axis...

OBJECTIVE: To compare cost-effectiveness of oral sildenafil citrate, administered after onset of labor, with standard care to health system funders in the UK and Australia. METHODS: We conducted a modeled cost-effectiveness analysis, measuring costs and quality adjusted life years (QALYs), using a decision-analytic model covering onset of labor to 1 month post-birth. The relative risk of emergency cesarean section and operative vaginal birth was taken from a Phase 2 placebo controlled double blinded randomized control trial...

Postpartum femoral neuropathy has a reported incidence of less than 1% and its total recovery time extends up to 6 months to a year. A multidisciplinary approach is vital to rule out permanent disability and to assure a correct diagnosis and earlier rehabilitation. We report a case of a 37-year-old puerperal woman with a history of intrapartum epidural analgesia, who presented post-labor unilateral lower-limb motor weakness and sensory loss, with functional compromise on independent gait. A multidisciplinary team consisting of an anesthesiologist, a physiatrist, a neurologist, and an obstetrician was then established...

OBJECTIVES: Apparently uncomplicated low-risk pregnancies, especially first time births, account for a significant proportion of adverse birth outcomes. Improved risk stratification with a simple bedside scan on admission in early labor could potentially reduce adverse intrapartum outcomes. The aim of this feasibility study was to assess a cohort of low-risk subjects with admission ultrasonography at the onset of labor with a view to conducting a future randomized controlled trial (RCT)...

OBJECTIVES: To determine emergency delivery rates for fetal compromise after epidural analgesia and to study whether these rates are increased in fetuses with reduced placental function reserve compared to alternative or no analgesia use. METHODS: A nationwide cohort of the Dutch national birth registry including 629,951 singleton pregnancies between 36+0 and 42+0 weeks of gestation with either epidural analgesia (n=120,426), alternative analgesia (n=86,957) or no analgesia (n=422,568) during labor...

OBJECTIVES: To report on the association of epidural analgesia with emergency delivery for fetal compromise compared to remifentanil patient-controlled analgesia and describe the association with birthweight for gestational age. METHODS: A post hoc per-protocol analysis of the RAVEL study, a multicentre randomised controlled equivalence trial. Singleton, non-anomalous pregnancies between 36+0 and 42+6 weeks of gestation were at pain relief request randomised to either epidural analgesia or remifentanil patient-controlled analgesia...

The success of in-utero or intrapartum treatment for congenital diaphragmatic hernia (CDH) can be impacted by poor placental function; however, this relationship has not yet been studied. To analyze placental histomorphology in CDH, the frequencies of 24 independent clinical and 48 placental phenotypes were compared. Slides from 103 CDH placentas (group 1) and 133 clinical umbilical cord (UC) compromise/anatomical UC abnormality placentas without CDH (group 2) were subjected to hematoxylin/eosin staining and CD34 immunostaining and then examined...

INTRODUCTION: Neonates with cardiorespiratory compromise at delivery are at substantial risk of hypoxic neurologic injury and death. Though mitigation strategies such as ex-utero intrapartum treatment (EXIT) exist, the competing interests of neonatal beneficence, maternal non-maleficence, and just distribution of resources require consideration. Due to the rarity of these entities, there are few systematic data to guide evidence-based standards. This multi-institutional, interdisciplinary approach aims to elucidate the current scope of diagnoses that might be considered for such treatments and examine if treatment allocation and/or outcomes could be improved...

The onset of regular, strong, and progressive uterine contractions may result in both mechanical (compression of the fetal head and/or umbilical cord) and hypoxic (repetitive and sustained compression of the umbilical cord or reduction in uteroplacental oxygenation) stresses to a human fetus. Most fetuses are able to mount effective compensatory responses to avoid hypoxic-ischemic encephalopathy and perinatal death secondary to the onset of anaerobic metabolism within the myocardium, culminating in myocardial lactic acidosis...
