introduction: postoperative sore throat is a common complaint in patients with endotracheal intubation and has potentially dangerous complications. this randomized controlled trial study investigated the incidence of postoperative sore throat after general anesthesia when betamethasone gel is applied to a tracheal tube compared with when iv dexamethasone is prescribed.   materials and methods: ...

BACKGROUND The Entropy Module anaesthesia monitor displays two spectral entropy-based indices, response entropy (RE) and state entropy (SE). The difference between RE and SE (RE-SE), which mainly reflects electromyography activation, is thought to indicate the adequacy of antinociception. Little is known, however, about the effects of neuromuscular blocking agents on the RE-SE. We investigated ...

Cells at the tips of budding branches in the Drosophila tracheal system generate two morphologically different types of seamless tubes. Terminal cells (TCs) form branched lumenized extensions that mediate gas exchange at target tissues, whereas fusion cells (FCs) form ring-like connections between adjacent tracheal metameres. Each tracheal branch contains a specific set of TCs, FCs, or both, bu...

UNLABELLED Tracheal secretion leakage might lead to ventilator-associated pneumonia. Standard tracheal tube cuffs are cylindrical in shape. Bronchial tree aspiration is observed in the presence of leakage past tracheal tube cuffs. The new TaperGuard tracheal tube has a cuff in the shape of a cone, preventing from the development of microtubules and microaspiration. The aim of the study was to c...

Tracheal rupture is a rare condition, and its most common cause is head and neck injury. Nontraumatic disruption of the anterolateral fibrocartilaginous trachea is an exceptional complication following thyroidectomy with few cases reported in literature. We report a case of upper tracheal necrosis arising 15 days after uneventful total thyroidectomy and resulted in pneumomediastinum and subcuta...

BACKGROUND beta1-Adrenoceptor antagonists suppress the haemodynamic and arousal responses to tracheal intubation. The Entropy Module shows two spectral entropy-based indices, response entropy (RE) and state entropy (SE). The difference between RE and SE (RE-SE) may reflect nociception during general anaesthesia. In the present study, we investigated the effect of landiolol on entropy indices in...

STUDY OBJECTIVE To determine the usefulness of routinely inserting a hollow airway exchange catheter (jet stylet) prior to tracheal extubation of adult patients with risk factors for difficult tracheal intubation. DESIGN Prospective, 1-year study of 40 consecutive patients undergoing mechanical ventilation who had one or more risk factors for difficult tracheal reintubation. SETTING Surgica...

BACKGROUND Oxygenation via the cricothyroid membrane (CTM) may be required in emergencies, but inadvertent tracheal cannulation may occur. In this study, we compared airway injury between the tracheal and CTM sites using different techniques for airway access. METHODS Anesthesiologists performed 4 airway access techniques on excised porcine tracheas. The techniques were 1) wire-guided (WGT), ...
