OBJECTIVE: To test the hypothesis that intrauterine hyperoxemia is associated with an increased risk of neonatal morbidity. METHODS: This was a secondary analysis of a prospective study of singleton, nonanomalous deliveries at or beyond 37 weeks of gestation at an institution with a universal umbilical cord gas policy from 2010 to 2014. The primary outcome was a composite of neonatal morbidity including neonatal death, meconium aspiration syndrome, intubation, mechanical ventilation, hypoxic-ischemic encephalopathy, and hypothermic therapy...

In 2006, the American Academy of Pediatrics and the American Heart Association published the 2005 guidelines on neonatal resuscitation. Before the 2005 guidelines, management of a newborn with meconium-stained amniotic fluid included suctioning of the oropharynx and nasopharynx on the perineum after the delivery of the head but before the delivery of the shoulders. The 2005 guidelines did not support this practice because routine intrapartum suctioning does not prevent or alter the course of meconium aspiration syndrome in vigorous newborns...

BACKGROUND: Extracorporeal membrane oxygenation (ECMO) was used in neonates with severe cardiopulmonary failure who failed to respond to conventional therapy. We started to apply neck venoarterial ECMO (VA-ECMO) in neonatal patients from 2000. In this study, we have focused on neonates who received ECMO support and described the current status of ECMO in neonates for both cardiac and pulmonary support and the risk factors associated with their outcomes. METHODS: Data were retrieved from our ECMO database for the neonates (age < 28 days) who received neck VA-ECMO support from January 2005 to June 2015...

BACKGROUND: Cesarean delivery (CD) rates have risen globally with nearly 50% of the non-indicated CDs worldwide in China and Brazil. In China's One Child Policy era (1979-2015) most deliveries were women having their only child. Family size is a major determinant of the safety of medically non-indicated CD or CD on maternal request. The goal of this study is to document CD rates, indications, and analyze the relative safety of non-indicated CD compared to SVD and intrapartum CD. METHODS: Univariate and multivariate logistic regression analyses of the association between mode of delivery and short-term maternal and perinatal outcomes were performed on a cross-section of all deliveries at 39 hospitals in 14 provinces of China in 2011, presented as adjusted odds ratio (aOR), 99% confidence intervals (CI)...

Meconium aspiration syndrome (MAS) triggers inflammatory and oxidative pathways which can inactivate both pulmonary surfactant and therapeutically given exogenous surfactant. Glucocorticoid budesonide added to exogenous surfactant can inhibit inflammation and thereby enhance treatment efficacy. Neonatal meconium (25 mg/ml, 4 ml/kg) was administered intratracheally (i.t.) to rabbits. When the MAS model was prepared, animals were treated with budesonide i.t. (Pulmicort, 0.25 mg/kg, M+B); with surfactant lung lavage (Curosurf®, 10 ml/kg, 5 mg phospholipids/ml, M+S) followed by undiluted Curosurf® i...

OBJECTIVES: Inhaled nitric oxide (iNO) is effective in conjunction with tracheal intubation (TI) and mechanical ventilation (MV) for treating arterial pulmonary hypertension and hypoxemic respiratory failure (HRF) in near-term and term newborns. Non-invasive respiratory support with nasal continuous positive airway pressure (CPAP) is increasingly used to avoid morbidity associated with TI and MV, yet the effectiveness of iNO delivery via nasal CPAP remains unknown. To evaluate the effectiveness of iNO delivered via the bubble nasal CPAP system in term and preterm newborns with HRF...

BACKGROUND: There have been few reports on the outcome of extracorporeal membrane oxygenation (ECMO) in newborn Japanese infants. METHODS: A review was carried out of 61 neonates with ECMO between January 1995 and December 2015 at a single center. ECMO was used in neonates with oxygenation index >20 after conventional treatment. Background factors, such as etiology, vascular access mode (veno-venous [VV] or veno-arterial [VA]), number of days with ECMO, and early ECMO (within 24 h after birth), were analyzed in relation to outcome with respect to survival to hospital discharge (SHD)...

BACKGROUND: Although respiratory distress syndrome (RDS) is considered a disease of prematurity, there is evidence to suggest heterogeneity between early and late gestation RDS. We examined the epidemiologic features of RDS occurring at early and late gestation. METHODS: We conducted a retrospective cohort study including live births in the United States in 2005-06, with information obtained from the National Center for Health Statistics. Early (<32 weeks) and late gestation RDS (≥39 weeks) were contrasted in terms of risk factors and associations with pregnancy complications, obstetric intervention and co-morbidity...

Treatment of gastroschisis often requires multiple surgical procedures to re-establish abdominal domain, reduce abdominal contents, and eventually close the abdominal wall. In patients who have concomitant respiratory failure requiring extracorporeal membrane oxygenation (ECMO), this process becomes further complicated. This situation is rare and only five such cases have been reported in the ECMO registry database. Management of three of the five patients along with results and implications for future care of similar patients is discussed here...

Meconium aspiration syndrome (MAS) is characterized by surfactant inactivation and inflammation. As lung epithelial cells up-regulate nitric oxide (NO) in response to inflammation, the NO production following meconium exposition was examined in relation to expression of Deleted in Malignant Brain Tumors 1 (DMBT1), a protein with functions in innate immunity and inflammatory regulation. Here, DMBT1 expression was analyzed by immunohistochemistry in postmortem lung sections from patients with MAS. The lung epithelial cell line A549, stably transfected with a DMBT1 (DMBT1+ cells) expression plasmid or with an empty expression plasmid (DMBT1- cells), was exposed to meconium...

INTRODUCTION: Inhaled nitric oxide (iNO) is the standard therapy for infants with persistent pulmonary hypertension of the newborn (PPHN). Recently, sildenafil has been evaluated as an alternative or adjunctive pulmonary vasodilator. OBJECTIVE: To assess the effectiveness of adding sildenafil as an early adjunctive therapy together with iNO when treating newborns with PPHN and/or hypoxemic respiratory failure. METHODS: This is a randomized placebo trial on newborns with gestational age > 34 weeks, postnatal age < 48 hours, and diagnosed with PPHN (oxygen index (OI) ≥ 20)...
