How does fetal inflammatory response syndrome change fetal response to hypoxia? An experimental study in a fetal sheep model.

Introduction: Fetal inflammatory response syndrome associated with acidosis during labor is a high-risk situation for the fetus. This study evaluated hemodynamic, gasometric, and heart rate variability changes during acute fetal inflammatory response syndrome associated with hypoxia, compared with isolated hypoxia.

Material And Methods: Acute fetal inflammatory response syndrome was obtained via an intravenously injection of lipopolysaccharide derived from Escherichia coli.

[Fetal monitoring: Current limitations and new approaches based on analysis of the fetal autonomic nervous system].

Objective: Currently, fetal monitoring during labor is based on visual analysis of the fetal heart rate (FHR). This test is imperfect, with high intra- and inter-observer variability and a moderate to poor prediction of the occurrence of neonatal acidosis or anoxic-ischaemic encephalopathy. In situations where there is an intermediate risk of acidosis, it is possible to use second-line tests such as blood scalp sampling (with pH or lactate measurement) or ST segment analysis of the fetal ECG.

Anomalous hepatic drainage and platypnea-orthodeoxia in cyanotic children.

The aetiology of cyanosis could be unclear in children, even for specialised paediatricians. Two cases were reported: first, a 6-year-old child with features of left isomerism and Fallot was fortuitously diagnosed with anomalous hepatic venous drainage before complete repair. Second, a newborn with an antenatal diagnosis of ductus venosus agenesis had an isolated intermittent right-to-left atrial shunt when upright, with favourable outcome, in contrast to the association with significant heart malformations including inferior caval vein interruption.

Intact cord resuscitation in newborns with congenital diaphragmatic hernia: insights from a lamb model.

Introduction: Congenital diaphragmatic hernia (CDH) is a rare condition characterized by pulmonary hypoplasia, vascular dystrophy, and pulmonary hypertension at birth. Validation of the lamb model as an accurate representation of human CDH is essential to translating research findings into clinical practice and understanding disease mechanisms. This article emphasizes the importance of validating the lamb model to study CDH pathogenesis and develop innovative therapeutics.

Diastolic ventricular function in persistent pulmonary hypertension of the newborn.

Background: Persistent pulmonary hypertension of the newborn (PPHN) is usually considered a consequence of impaired pulmonary circulation. However, little is known regarding the role of cardiac dysfunction in PPHN. In this study, we hypothesized that the tolerance for pulmonary hypertension in newborn infants depends on the biventricular function.

Surgical Risk Factors for Delayed Oral Feeding Autonomy in Patients with Left-Sided Congenital Diaphragmatic Hernia.

Background: Congenital diaphragmatic hernia (CDH) is a rare disease associated with major nutritional and digestive morbidities. Oral feeding autonomy remains a major issue for the care and management of these patients. The aim of this study was to specify the perinatal risk factors of delayed oral feeding autonomy in patients treated for CDH.

Fetal Lung Volume Appears to Predict Respiratory Morbidity in Congenital Diaphragmatic Hernia.

Congenital diaphragmatic hernia (CDH) is associated with pulmonary hypoplasia and respiratory morbidity. To assess whether respiratory morbidity during the first 2 years of life in infants with left-sided CDH is associated with fetal lung volume (FLV) evaluated by the observed-to-expected FLV ratio (o/e FLV) on antenatal magnetic resonance imaging (MRI). In this retrospective study, o/e FLV measures were collected.

Systemic Inflammation Is Associated with Pulmonary Hypertension in Isolated Giant Omphalocele: A Population-Based Study.

Our objective is to determine perinatal factors contributing to the development of pulmonary hypertension (PH) in patients with isolated giant omphaloceles (GO). All cases of omphaloceles that underwent prenatal and postnatal care at the University Hospital of Lille between 1996 and 2021 were reviewed. We included all infants with isolated GO, including at least a part of the liver, who were treated by delayed surgical closure.

Antenatal Assessment of the Prognosis of Congenital Diaphragmatic Hernia: Ethical Considerations and Impact for the Management.

Congenital diaphragmatic hernia (CDH) is associated with abnormal pulmonary development, which is responsible for pulmonary hypoplasia with structural and functional abnormalities in pulmonary circulation, leading to the failure of the cardiorespiratory adaptation at birth. Despite improvement in treatment options and advances in neonatal care, mortality remains high, at close to 15 to 30%. Several risk factors of mortality and morbidities have been validated in fetuses with CDH.

High-frequency oscillatory ventilation versus conventional ventilation in the respiratory management of term neonates with a congenital diaphragmatic hernia: a retrospective cohort study.

Unlabelled: Conventional mechanical ventilation (CMV) has been recommended as the first-line mode of respiratory support for neonates born with a congenital diaphragmatic hernia (CDH). However, older studies suggested that protective high-frequency oscillatory ventilation (HFOV) with low-mean airway pressure (MAP) may limit lung injury. We aimed to compare low-MAP HFOV with CMV in neonates with CDH in terms of patient outcomes.

Case report: risk of skin necrosis related to injectable vancomycin in critically ill newborn infants.

Background: Vancomycin is commonly used as part of empiric antibiotic therapy in the preterm infants who develop signs and symptoms of infection. Although skin necrosis has been noted to occur following injection of vancomycin into a peripheral vein in an adult patient, this complication has not been previously described in a preterm infant.

Case Presentation: We report the case of a very low birthweight male infant born at 30 weeks gestational age who developed skin necrosis, most likely as a complication of vancomycin administration via a peripheral venous catheter.

Efficacy of Intact Cord Resuscitation Compared to Immediate Cord Clamping on Cardiorespiratory Adaptation at Birth in Infants with Isolated Congenital Diaphragmatic Hernia (CHIC).

Resuscitation at birth of infants with Congenital Diaphragmatic Hernia (CDH) remains highly challenging because of severe failure of cardiorespiratory adaptation at birth. Usually, the umbilical cord is clamped immediately after birth. Delaying cord clamping while the resuscitation maneuvers are started may: (1) facilitate blood transfer from placenta to baby to augment circulatory blood volume; (2) avoid loss of venous return and decrease in left ventricle filling caused by immediate cord clamping; (3) prevent initial hypoxemia because of sustained uteroplacental gas exchange after birth when the cord is intact.

Prostaglandin E1 in infants with congenital diaphragmatic hernia (CDH) and life-threatening pulmonary hypertension.

Background: Suprasystemic pulmonary hypertension (PH) is highly predictive of pulmonary morbidity and death in infants with congenital diaphragmatic hernia (CDH).

Objectives: To report the effects and tolerability of Prostaglandin E (PGE) in newborns with severe CDH and life-threatening PH.

Methods: Newborn infants with isolated CDH and life-threatening PH defined by an acute worsening of the cardiorespiratory function, and bidirectional or exclusive right-to-left shunting across the ductus arteriosus (DA) with an acceleration of the blood flow >1.
