RATIONALE Currently used definitions of bronchopulmonary dysplasia (BPD) lack a continuous measure of disease severity. OBJECTIVES To determine if an indirect measure of V./Q. mismatch is reliable when simplified to facilitate more widespread use for grading disease severity in BPD at 36 weeks postmenstrual age. METHODS We used prospectively collected(More)
Glue sniffing is epidemic among children living in poverty in Latin America. Previous research has shown that abused inhalants such as toluene share pharmacological properties with anxiolytic drugs, and that personality factors such as degree of anxiety have been proposed to modulate the effects of these drugs. To study this interaction in an animal model,(More)
Venoarterial (VA) extracorporeal life support (ECLS) for neonatal respiratory failure is associated with increased mortality compared to venovenous (VV) ECLS. It is unclear if this is a causal relationship or reflects differences in baseline disease severity between infants managed with these two strategies. Our objective was to identify clinical variables(More)
Continuous positive airway pressure (CPAP) has been used for respiratory support in premature infants for more than 40 years and is now a cornerstone of modern neonatal care. Clinical research on CPAP has primarily focused on understanding which devices and pressure sources best implement this therapy. In contrast, less research has examined the optimal(More)
BACKGROUND Conventional mechanical ventilation (CMV) of neonates has been used as a treatment of respiratory failure for over 30 years. While CMV facilitates gas exchange, it may simultaneously damage the lung. Positive end expiratory pressure (PEEP) has received less attention than other ventilation parameters when considering this balance of benefit and(More)
