We examined the relationship between C-fiber-mediated, ozone-induced rapid shallow breathing and airway epithelial cell injury at different airway sites within the lower respiratory tract of conscious Wistar rats (n = 24). We combined an acute 8-h ozone inhalation with vagal perineural capsaicin treatment, a selective C-fiber conduction block, and 5-bromo-2'-deoxyuridine (BrdU) labeling as an i...

Imaging plays a role in the anatomic assessment of the airway and adjacent structures. This article discusses the use of 3-dimensional (3D) imaging (cone beam computed tomography [CBCT]) to evaluate the airway and selected regional anatomic variables that may contribute to obstructive sleep-disordered breathing (OSDB) in patients. CBCT technology uses a cone-shaped x-ray beam with a special ima...

O R IG IN A L A R T IC L E INTRODUCTION Adequate postoperative analgesia is considered to be a major key for reducing pul monary morbidity and improving the outcome. Thoracic epidural anesthesia (TEA) has been proposed as a reliable analgesic method following thoracic surgery. Most of these benefi ts, however, relate to the postoperative or to the so-called perioperative period. Some case repor...

A 21-year-old male (body mass index: 28.3) with a history of asthma and reactive airway disease since childhood underwent left shoulder arthroscopy and labral repair surgery under monitored anesthesia care. Because the procedure was performed in the beach chair position, access to the patient's airway was limited throughout. To avoid general anesthesia and to limit potential complications assoc...

The elective surgical airway is the definitive management for a tracheal stenotic lesion that is not a candidate for tracheal resection, or who has failed multiple-tracheal dilations. This case report details the management of a patient who has failed an elective awake tracheostomy secondary to the inability to be intubated as well as severe scar tissue at the surgical site. A combination of re...

There are three main types of anaesthesia General anaesthesia: the patient is sedated, using either intravenous medications or gaseous substances, and occasionally muscles paralysed, requiring control of breathing by mechanical ventilation Regional anaesthesia: this can be described as central where anaesthetic drugs are administered directly in or around the spinal cord, blocking the nerves of...

[1] We use data from campaign and continuous GPS sites in southeast Alaska and the neighboring region of Canada to constrain a regional tectonic block model that estimates block angular velocities and derives a self‐consistent set of fault slip rates from the block motions. Present‐day tectonics in southeast Alaska is strongly influenced by the collision of the Yakutat block. Our model predicts...

Sympathetic ganglion block (SGB) or intravenous regional block (IVRB) has been recommended for pain management in patients with complex regional pain syndrome type I (CRPS-I). Forty-five patients were initially selected but only 43 were accepted for the study. The present study evaluated the efficacy of IVRB produced by combining 70 mg lidocaine with 30 µg clonidine (14 patients, 1 male/13 fema...

Regional anaesthesia may affect respiratory muscle function, pulmonary bronchial tone and postoperative pulmonary dysfunction. These effects on respiratory function depend on the concentration of the local anaesthetic used and, mostly, on the location of the regional block. Most peripheral nerve blocks have no effect on respiratory function and are, therefore, often recommended as the technique...
