the stimulatory effect of the extract of portulaca oleracea (p. olerace) on β-adrenoceptor of tracheal smooth muscle was examined. to examine β-adrenoceptor stimulatory effect, concentration response curve to isoprenaline was obtained in pre-contracted tracheal smooth muscle in the presence of three concentrations of aqueous-ethanolic extract, propranolol and saline. values of ec50 (the effecti...

The Montgomery tracheal tube (T-tube) is a device used as a combined tracheal stent and airway after laryngotracheoplasty for patients with tracheal stenosis. This device can present various challenges to anesthesiologists during its placement, including the potential for acute loss of the airway, inadequate administration of inhalation agents, and inadequacy of controlled mechanical ventilatio...

Tracheal rupture is a rare complication of endotracheal intubation. We present a case of tracheal rupture that was diagnosed intraoperatively after the use of an NIM EMG endotracheal tube. A 66-year-old female with a recurrent multinodular goiter was scheduled for total thyroidectomy. Induction of anesthesia was uncomplicated. Intubation was atraumatic using a 6 mm NIM EMG endotracheal tube (ET...

Obstructive fibrinous tracheal pseudomembrane is a rare, but potentially fatal complication associated with endotracheal intubation. It has been known that the formation of tracheal pseudomembrane is related with intracuff pressure during endotracheal intubation or infectious cause. But in the patient described in this case, pseudomembrane formation in the trachea was associated with subglottic...

To evaluate the potential utility of a self-expandable intratracheal nitinol stent with flared ends for the treatment of tracheal collapse in dogs, endotracheal stenting therapy was performed under fluoroscopic guidance in four dogs with severe tracheal collapse. During the 4 to 7 month followup, after stent implantation, clinical signs, including dyspnea and respiratory distress, dramatically ...

IN-LABORATORY FULL POLYSOMNOGRAPHY (PSG) WITH MANUAL ANALYSIS IS CONSIDERED TO BE THE GOLD STANDARD FOR THE DIAGNOSIS OF SLEEP APNEA-HYPOPNEA SYNDROME (SAHS).1 However the procedure is labor intensive and time consuming, and the capacity for PSG is limited considering the high prevalence of SAHS.2 Many portable recording devices intended to assess SAHS have been developed. The American Sleep Di...

A 52-year-old woman with tracheal lesions underwent tracheal resection and carina reconstruction directly because histopathologic diagnosis was not obtained before surgery. Postoperative pathological analysis confirmed a diagnosis of mucosa-associated lymphoid tissue (MALT) lymphoma. Subsequently, she suffered serious complications of tracheal stenosis, bronchial stenosis, and tracheoesophageal...

Tracheal stenosis is an uncommon but serious complication of prolonged intubation and tracheostomy patients. Treatment is often provided by otorhinolaryngologists or interventional pulmonologists, but because symptoms may not appear for weeks or months after extubation, primary care physicians are frequently the first to encounter this complication. On presentation, tracheal stenosis may be mis...

We present a case of one-stage radical surgical treatment of a 24-year-old female patient with cicatricial granulating tracheal stenosis after tracheostomy complicated by esophageal-tracheal fistula and an extensive defect of the anterior wall of the trachea after numerous unsuccessful attempts to correct the narrowing of the trachea and eliminate the fistula by endoscopic and open surgical tec...
