OBJECTIVE To determine the prevalence of synchronous airway lesions and esophagitis in children younger than 18 months undergoing adenoidectomy for adenoid hypertrophy and upper airway obstruction. DESIGN Retrospective review spanning 4.5 years. SETTING Tertiary care children's hospital. PATIENTS All children younger than 18 months who underwent adenoidectomy for upper airway obstruction ...

Respiratory failure in infants and children is a common cause of ICU admission, and diseases that jeopardize the airway are the most frequent cause of cardiac arrest in neonatal and pediatric patients.1,2 In neonates specifically, there are numerous causes for respiratory distress, with upper-airway obstruction being an important source of morbidity and mortality.3,4 This case will discuss the ...

Various sites along the upper airway (UA) are prone to narrow and collapse in patients affected by obstructive sleep apnoea. Sleep stages may eventually alter these sites. The present study was designed to determine the site(s) of UA obstruction and the influence of sleep stage on the pattern of obstruction. Twenty eight obstructive sleep apnoea patients underwent UA pressure measurements durin...

Surgical success for obstructive sleep apnea (OSA) depends on identifying sites of obstruction in the upper airway. In this study, we investigated sites of obstruction by evaluating dynamic changes in the upper airway using drug-induced sleep computed tomography (DI-SCT) in patients with OSA. Thirty-five adult patients with OSA were prospectively enrolled. Sleep was induced with propofol under ...

Our study was to assess whether there were differential effects of nasal continuous positive airway pressure (nCPAP) on different kinds of obstruction in either upper or lower airways in patients with chronic obstructive pulmonary disease (COPD). nCPAP (6 cmH2O for ten minutes) was applied to 7 patients with reversible extrathoracic upper airway obstruction (RUAO) and 3 patients with fixed extr...

Airway management of patients with tracheal stenosis is highly challenging and even establishing a surgical airway may be difficult in these patients. A 24 year old female developed pinhole restenosis after undergoing web resection reconstruction. After other modes ventilation had failed, we used the Manual jet ventilator endotracheal tube assembly as rescue device performed intermittent low-fr...

Congenital central hypoventilation syndrome (CCHS) is the failure of the autonomic system to control adequate ventilation while asleep with preserved ventilatory response while awake. We report a case of a patient with CCHS who presented with intrathoracic and extrathoracic airway obstruction after tracheostomy tube decannulation and phrenic nerve pacer placement. Nocturnal polysomnography (NPS...

This study examines the role of endothelial leukocyte adhesion molecule-1 (ELAM-1) in the development of the acute airway inflammation (cell influx) and late-phase airway obstruction in a primate model of extrinsic asthma. In animals sensitive to antigen, a single inhalation exposure induced the rapid expression of ELAM-1 (6 h) exclusively on vascular endothelium that correlated with the influx...

Poiseuille’s law is central to the understanding and management of all airway obstructions in children, with the clinical impact of even a small reduction in radius being compounded by the inverse relationship of the resistance to the radius to the power 4. Indeed deterioration from a ‘mild’ obstruction to life threatening airway compromise may be heralded by slight decrease in airway diameter ...
