The aim of this study was to determine whether an acute ozone exposure affects breathing, and the ability of pulmonary surfactant to maintain the patency of terminal conducting airways. BALB/c mice were exposed to ozone (1 part per million (ppm)) for 2, 4, 6, and 8 h. They were examined with plethysmography and with bronchoalveolar lavage (BAL) 24 h later. The BAL fluid was analysed for the pre...

Relapsing polychondritis (RP) is a rare disease that is characterized by recurrent inflammation and destruction of cartilage and connective tissues. RP can have significant airway pathology that may require procedures to maintain airway patency and thus may have serious implications for anesthesiologists. Anesthesiologists must be prepared to deal with the possible complications that may occur ...

Pediatric laryngotracheal injuries as a result of blunt neck trauma are exceedingly rare, but they have the potential for fatal consequences if not identified and managed appropriately. Two cases on the spectrum of laryngotracheal trauma are presented followed by an overview of pediatric laryngotracheal trauma with a focus on acute airway management. Special considerations must be taken into ac...

Parapharyngeal abscess is a life-threatening infection. It occurs due to spread of infection form anatomical locations in the vicinity of the space. Management of the deep neck infection is governed by the general condition of the patient, the extent of disease and patency of airway. In treatment of deep neck infections intensive antibiotic therapy and surgical drainage are complementary to eac...

Intubation of the left main bronchus via a tracheostomy tube was performed in a patient with local recurrence of lung cancer associated with invasion and obstruction of the left main bronchus after right sleeve pneumonectomy. The result was satisfactory not only for preventing asphyxia, but also for maintaining the patency of the airway after extubation of the endotracheal tube.

Background: The management of a hyperdivergent growth pattern is one the most challenging in orthodontics and different treatments are advocated. present study analyses effectiveness elastodontic therapy with AMCOP® devices treating children class II malocclusion effect on upper airway patency. Methods: group included 21 patients (10 males 11 females, mean age 8.22 ± 1.17 years) treated devices...

Mediastinal Masses have always posed as a nightmare even for the skilful anaesthesiologists. The compression effects, the proximity to major vascular and airway structures, the complex surgical approaches has altogether made both the diagnostic and therapeutic procedures a high risk event. The scenario is more troublesome if the patient is an infant or child. Here the anaesthesiologists has alm...

The upper airway is a vital part of the respiratory tract. Although the upper airway serves several functions, protection of the airway and preservation of airway patency are the most essential functions subserved by upper airway reflexes. Various types of nerve endings have been identified in and under the epithelium of the upper airway, and afferent nerve endings are the natural starting of a...
