Pulmonary capillary hemangiomatosis is a rare entity characterized by the proliferation of capillaries into alveolar walls, interlobular septa, pleura and pulmonary interstitium, without malignant characteristics, with almost constant association with pulmonary hypertension. Until now two cases of congenital presentation have been reported in the literature. This is the third case in a newborn; he has not followed the usual pattern associated with pulmonary hypertension as occurs in most patients with this pathology; the highest incidence is among 20-40 years old...

OBJECTIVE: Providing skin-to-skin care (SSC) to preterm infants is standard practice in many neonatal intensive care units. There are conflicting reports on the stability of oxygen saturation (SpO2) during SSC, which may create a barrier to a wider implementation of SSC to infants receiving respiratory support. Regional cerebral oxygenation (rcO2) measured using near-infrared spectroscopy can serve as a surrogate parameter for cerebral oxygen delivery and consumption. We hypothesised that rcO2 during SSC would be similar to standard care in preterm infants receiving respiratory support...

BACKGROUND: Tolerating higher partial pressures of carbon dioxide (PCO2) in mechanically ventilated extremely low birthweight infants to reduce ventilator-induced lung injury may have long-term neurodevelopmental side effects. This study analyses the results of neurodevelopmental follow-up of infants enrolled in a randomised multicentre trial. METHODS: Infants (n=359) between 400 and 1000 g birth weight and 23 0/7-28 6/7 weeks gestational age who required endotracheal intubation and mechanical ventilation within 24 hours of birth were randomly assigned to high PCO2 or to a control group with mildly elevated PCO2 targets...

BACKGROUND: In recent years, early nasal continuous positive airway pressure (nCPAP) as respiratory support for preterm infants is being advocated as an alternative to prophylactic surfactant and treatment with mechanical ventilation. A number of infants treated with early nCPAP do not need treatment with surfactant, but few studies provide data on this. Since the 1990s, the first approach to respiratory support to preterm infants in Denmark has been early nCPAP combined with surfactant administration by the INSURE method by which the infant is intubated and surfactant administration is followed by rapid extubation to nCPAP if possible...

BACKGROUND: Severe bronchopulmonary dysplasia (BPD) often leads to prolonged mechanical ventilation lasting several months. Cyanotic episodes frequently occur in these patients, which necessitate long-term sedation and/or intermittent muscle paralysis. Neurally adjusted ventilatory assist (NAVA) might provide precisely the amount of support that these patients need without sedation. METHODS: We reviewed the medical records of preterm infants who underwent a tracheostomy and required mechanical ventilation for more than 6 months during a period of 6 years...

Nasal continuous positive airway pressure (nCPAP) is a widely accepted technique of non-invasive respiratory support in spontaneously-breathing premature infants with respiratory distress syndrome (RDS). Surfactant administration techniques compatible with nCPAP ventilation strategy are actively investigated. Our aim is to set up and validate a respiratory distress animal model that can be managed on nCPAP suitable for surfactant administration techniques studies. Surfactant depletion was induced by bronchoalveolar lavages (BALs) on 18 adult rabbits...

BACKGROUND: Prematurity is often complicated by respiratory support, including invasive mechanical ventilation (IMV) and non-invasive support (NIS). Compared to IMV, NIS reduces injury to the lung and brain. Prematurity may also disrupt glomerular architecture. Whether NIS differentially affects glomerular architecture is incompletely understood. We hypothesized that IMV would lead to greater disruption of glomerular architecture than NIS. METHODS: This is a secondary analysis of kidneys from moderately preterm lambs delivered at ~131d gestation (term ~150d) that had antenatal steroid exposure and surfactant treatment before resuscitation by IMV...

BACKGROUND: Nasal continuous positive airway pressure (NCPAP) is a strategy for maintaining positive airway pressure throughout the respiratory cycle through the application of bias flow of respiratory gas to an apparatus attached to the nose. Treatment with NCPAP is associated with decreased risk of mechanical ventilation and might be effective in reducing chronic lung disease. Nasal intermittent positive pressure ventilation (NIPPV) is a form of noninvasive ventilation during which patients are exposed intermittently to higher levels of airway pressure, along with NCPAP through the same nasal device...

BACKGROUND: Chronic lung disease (CLD) occurs frequently in preterm infants. Bronchodilators have the potential effect of dilating small airways with muscle hypertrophy. Increased compliance and tidal volume and decreased pulmonary resistance have been documented with the use of bronchodilators in infants with CLD. Therefore, bronchodilators might have a role in the prevention and treatment of CLD. OBJECTIVES: To determine the effect of bronchodilators given as prophylaxis or as treatment for CLD on mortality and other complications of preterm birth in infants at risk for or identified as having CLD...

Importance: Clinicians aim to extubate preterm infants as early as possible, to minimize the risks of mechanical ventilation. Extubation is often unsuccessful owing to lung disease or inadequate respiratory drive. Objective: To conduct a systematic review and meta-analysis of interventions to improve rates of successful extubation in preterm infants. Data Sources: Searches were undertaken in PubMed and The Cochrane Library. Study Selection: The review was conducted using the methods of the Cochrane Collaboration and Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines...

Bronchopulmonary dysplasia (BPD) is the most common complication of preterm birth, with appreciable morbidity and mortality in a neonatal intensive care setting. Much interest has been shown in the identification of pathogenic pathways that are amenable to pharmacological manipulation (1) to facilitate the development of novel therapeutic and medical management strategies and (2) to identify the basic mechanisms of late lung development, which remains poorly understood. A number of animal models have therefore been developed and continue to be refined with the aim of recapitulating pathological pulmonary hallmarks noted in lungs from neonates with BPD...

The artificial placenta (AP) has for many decades captured the imagination of scientists and authors with popular fiction including The Matrix and Aldous Huxley's "Brave New World", depicting a human surviving ex-utero in an artificial uterine environment (AUE). For scientists this has fascinated as a way forward for extremely preterm infants (EPIs) born less than 28 weeks of gestation. Early successes with mechanical ventilation (MV) for infants born above 28 weeks of gestation meant that AP research lost momentum...

Respiratory transition at birth involves rapidly clearing fetal lung liquid and preventing efflux back into the lung while aeration is established. We have developed a sustained inflation (SIOPT) individualized to volume response and a dynamic tidal positive end-expiratory pressure (PEEP) (open lung volume, OLV) strategy that both enhance this process. We aimed to compare the effect of each with a group managed with PEEP of 8 cmH2O and no recruitment maneuver (No-RM), on gas exchange, lung mechanics, spatiotemporal aeration, and lung injury in 127 ± 1 day preterm lambs...

BACKGROUND: A 2005 consensus conference led by the National Association for Medical Direction of Respiratory Care (NAMDRC) defined prolonged mechanical ventilation (PMV) for adults as invasive and/or noninvasive mechanical ventilation (NIV) for ≥ 21 consecutive days for ≥ 6 h/d. In children, no such consensus definition exists. This results in substantial variability in definitional criteria, making study of the impact and outcomes of PMV across and within settings problematic. The objective of this work was to identify how PMV for children and neonates is described in the literature and to outline pediatric/neonatal considerations related to PMV, with the goal of proposing a pediatric/neonatal adaptation to the NAMDRC definition...
