INTRODUCTION Confirmation of proper endotracheal tube placement is one of the most important and lifesaving issues of tracheal intubation. The present study was aimed to evaluate the accuracy of tracheal ultrasonography by emergency residents in this regard. METHOD This was a prospective, cross sectional study for evaluating the diagnostic accuracy of ultrasonography in endotracheal tube plac...

Regulation of epithelial tube size is critical for organ function. However, the mechanisms of tube size control remain poorly understood. In the Drosophila trachea, tube dimensions are regulated by a luminal extracellular matrix (ECM). ECM organization requires apical (luminal) secretion of the protein Vermiform (Verm), which depends on the basolateral septate junction (SJ). Here, we show that ...

We report on a case of difficult endotracheal intubation in a patient with marked tracheal deviation at an angle of 90 degrees combined with stenosis due to kyphoscoliosis with vertebral body fusion. After induction of general anesthesia, a proper laryngeal view was easily obtained using a videolaryngoscope. But a tracheal tube could not be advanced more than 3 cm beyond the vocal cords due to ...

  Introduction: Tracheal stenosis is normally caused by trauma, infection, benign and malignant tumors, prolonged intubation or tracheostomy. The best treatment for tracheal stenosis is resection and anastomosis of trachea. Yet the major surgical complication of tracheal surgery is postoperative stenosis. The goal of this paper is to study the result of tracheal stenting as a replacement therap...

BACKGROUND Cyclic redistribution of air within the cuff during respiratory pressure changes creates a self-sealing mechanism which allows tracheal sealing, despite tracheal airway pressure being above baseline cuff inflation pressure. The aim of the present study was to investigate the effect of continuous automated cuff pressure regulation on tracheal sealing during cyclic respiratory pressure...

BACKGROUND A common complaint after endotracheal tube use is sore throat, which may be due to abrasion, ischemia-reperfusion injury, or an inflammatory reaction. Few studies have evaluated localized tracheal inflammation as part of the response to intubation. METHODS Inflammation of the trachea due to intubation was assessed in a swine model by following indicators of inflammation over time i...

I tracheobronchial injuries are fatal complications requiring immediate diagnosis and treatment. Unintentional one sided intubation, endotracheal tube cuff over-inflation, direct trauma with guides or boogie’s, double-lumen tube employment, tube replacement without cuff deflation and coughing against closed or blocked ventilation circuits are the possible causes.1, 2 Emergency or difficult intu...

BACKGROUND We evaluated the effects of conventional tracheal tube orientation on success of intubation through an intubating laryngeal mask airway (ILMA) in Mallampati class 3 or 4 patients. METHODS Two hundred adults, ASA I-II, Mallampati class 3 or 4, undergoing elective surgery under general anaesthesia were enrolled. All the patients were randomly allocated to either normal or reverse gro...

To the Editor: The tracheal tube introducer (bougie) is widely used to facilitate difficult intubation. However, single-use introducers, compared to reusable ones, appear to be more traumatic [1-3]. A 61-year-old woman with esophageal reflux and no predictive signs of difficult intubation received rapidsequence induction with application of cricoid pressure. Direct laryngoscopy revealed a Corma...

An 88-year-old woman with advanced Parkinson's disease (stage V on the Yahr scale) had difficulty in expectoration and underwent tracheostomy in 1999. In July 2004, granulation tissue was formed in the tracheal lumen at the tip of the tracheostomy tube, and a standard type silicone T-tube was inserted. Thereafter, she was cared for at home, where she was doing well until early March 2009, when ...
