Tracheal stenosis is the most common late airway complication of tracheostomy. Severe tracheal stenosis resulted in hemodynamic deterioration and impairment of respiratory system mechanics. We cared for an 86-year-old man with severe tracheal stenosis due to prolonged placement of a tracheostomy tube for 42-months. At the distal tip of the tracheostomy tube, bronchoscopy revealed severe trachea...

Introduction: In the present study, the prophylactic effect of vitamin C, as a potent anti-oxidant, on tracheal responsiveness to methacholine and ovalbumin, bronchoalveolar lavage fluid white blood cell (WBC) count and differential count, and also lung pathology in chronic obstructive pulmonary disease (COPD) -guinea pigs (cigarette exposed guinea pigs) were examined. In addition, the relax...

Receptor affinity and drug delivery to the receptor sites could be determinant factors for the increased bronchial responsiveness seen in asthma. Competitive antagonism blockade which is measured as dose ratio-l (DR-I) depends only on these two factors. Therefore, in this study we have examined histamine HI blockade by chlorpheniramine on isolated tracheal chains of asthmatic compared to co...

● Tracheal tube—commonly called an endotracheal tube. Note that a tracheal tube may be incorrectly placed in the esophagus, so the term does not mean a correctly positioned tube in the trachea. Moreover, a tracheostomy tube is not the same as a tracheal tube as used in these guidelines, even though both tubes are placed in the trachea. The procedure of placing a tracheal tube is still called en...

BACKGROUND Computed tomography (CT) is used to evaluate the human tracheobronchial tree because of its unsurpassed ability to visualize the airway and surrounding structures. To establish an ideal animal model for studying subglottic stenosis, we assessed the size and morphology of the normal rabbit's laryngotracheal airway by helical CT. We measured luminal dimensions at the levels of the aryt...

Tracheal agenesis is a rare cause of respiratory distress in the neonatal period. Temporary survival depends on ventilation through the esophagus. Thirty-eight case reports of tracheal agenesis (including one from this institution) have appeared in the literature. In this paper, we present the case reports of our 2 patients and review the literature. Tracheal agenesis is associated with a wide ...

Value of automated detection and assessment swallows during long-term measurement in tracheal cannula management

Tracheal stenosis represents a significant challenge. Surgeons continue to search for appropriate reconstructive techniques and grafting materials long tracheal segment reconstruction. Grafts can be classified as synthetic, allogenic, autogenic, transplant, engineered. Although none of these grafts have provided overwhelming success, acellular composite engineered shown early promise applied in...
