The study was undertaken to assess the airway function and its response to carbachol and salbutamol in infants recovering from wheezy bronchitis. In 82 children aged 3-33 mths, free from wheeze at the time of testing, and in 14 healthy infants, airway resistance (Raw) and thoracic gas volume (TGV) were measured using a body plethysmograph. Specific airway resistance (sRaw = Raw x TGV) was calcu...

Exogenous surfactant treatment inhibits antigen-induced airway obstruction in sensitized guinea-pigs. Aerosolized surfactant also improves respiratory function in asthmatic patients. The aim of the present study was to determine whether aerosolized surfactant inhibits nonallergic airway obstruction induced by acetylcholine. Anaesthetized Wistar rats were treated by aerosol with the beta2-adreno...

Previous studies of different samples have demonstrated associations between craniocervical angulation and craniofacial morphology, between airway obstruction by adenoids and craniofacial morphology, and between airway obstruction and craniocervical angulation. A hypothesis to account for the different sets of associations was suggested by Solow and Kreiborg in 1977. In the present study, the t...

mendations about external diameter.2 While internal diameter is important for the airway resistance, the magnitude of the external diameter may play a role in the development of postintubation airway edema, postintubation croup and subglottic stenosis in pediatric patients. Therefore, when choosing a certain size of tracheal tube in children, both internal and external diameters should be taken...

A modified nasopharyngeal tube is described that does not add airway dead space and resistance, is well tolerated, highly successful, and allows simultaneous use of oxygen prongs. This potentially reduces the need for surgical intervention to relieve high upper airway obstruction from Pierre-Robin syndrome and other causes.

Paradoxical breathing or “paradoxical inward rib cage movements” without frank sleep apnea is a clinical description of the “upper airway resistance syndrome”. Upper airway resistance syndrome is thought to be a distinct entity and not just a part of the continuum of obstructive sleep apnea; paradoxical breathing in children appears to be a separate entity from the classic patient with marked a...

Obstructive sleep apnea syndrome (OSAS) is a common and serious cause of metabolic, cardiovascular, and neurocognitive morbidity in children. Children with OSAS have increased upper airway resistance during sleep due to a combination of soft tissue hypertrophy, craniofacial dysmorphology, neuromuscular weakness, or obesity. Consequently, children with OSAS encounter a combination of oxidative s...
