Introduction: Tracheal chondrosarcoma (TCS) is a rare malignancy, with only 19 cases described in the literature to date. Case presentation: Herein, we presented the third-largest TCS with such an airway compromise that neither orotracheal intubation nor jet ventilation or even tracheostomy was possible. So, extracorporeal circulation was needed to excise the tumor in a one-stage procedure. Th...

Emergence from general anesthesia can be associated with coughing, agitation, and hemodynamic disturbances. Remifentanil may attenuate these responses. We have examined the effect of remifentanil on the hemodynamic response to the emergence from anesthesia and tracheal extubation. In a double-blind, randomized trial, we enrolled 50 adult patients undergoing abdominal surgery. All patients recei...

BACKGROUND The impact of cardiac surgery using cardiopulmonary bypass (CPB) on the respiratory mucociliary function is unknown. This study evaluated the effects of CPB and interruption of mechanical ventilation on the respiratory mucociliary system. METHODS Twenty-two pigs were randomly assigned to the control (n = 10) or CPB group (n = 12). After the induction of anesthesia, a tracheostomy w...

BACKGROUND The Airtraq laryngoscope is designed to allow visualization of the glottis without alignment of the oral, pharyngeal, and laryngeal axes. We hypothesized that this new airway device would facilitate tracheal intubation of morbidly obese patients. We compared tracheal intubation performance of standard Macintosh laryngoscope with the Airtraq laryngoscope in morbidly obese patients. ...

RATIONALE The occurrence of congenital cystic adenomatoid malformation (CCAM) and vascular ring (VR) is extremely rare. PATIENT CONCERNS We present a case of left CCAM with VR consisting of a left aortic arch and right descending aorta with left tracheal compression causing atelectasis. DIAGNOSES A high-risk male neonate with the diagnosis of left CCAM was diagnosed at 20 weeks gestational ...

Data on the management of perioperative airway and ventilatory support in children undergoing craniofacial surgery are limited. The purpose of this study was to review the authors' experience with airway management and ventilatory support during the perioperative period in children undergoing craniofacial surgery. Ninety-five consecutive children underwent 99 craniofacial procedures from July 1...

Endotracheal intubation is a procedure whereby a tube is inserted into the trachea to warrant and maintain adequate ventilation with good respiratory gas exchange in patients who undergo anesthesia for surgery or require invasive mechanical ventilation.Since 1967 the flexible fiberoptic bronchoscope was considered as an advanced device to intubate patients with difficult airway having surgery,“...

a twenty-year-old girl was referred with tracheal stenosis (ts) which was a consequence of prolonged intubation after head injury because of previous car accident. the patient was aphasic and had normal respiration. fiberoptic bronchoscopy showed complete tracheal obstruction at second tracheal ring level. distal trachea was normal through tracheostomy tube. removal of the tracheostomy tube and...

a 62-yr-old woman with a history of papillary carcinoma of thyroid who had undergone thyroidectomy and tracheostomy 5 years prior to admission, presented with bleeding from the site of tracheostomy. attempts to control the bleeding failed, and the patient was immediately transported to the operating room. awake intubation was performed and the endotracheal tube was sutured to the skin. a tear i...

The accuracy of tracheal temperature as a measure of core temperature is relatively poor during high-flow ventilation (6 litre min-1 fresh-gas flow). It is unknown if accuracy improves when lower fresh-gas flow rates are used. We tested the hypothesis that tracheal temperature accuracy would improve with low-flow ventilation (1 litre min-1). We studied 20 ASA Physical Status I and II patients u...
