Abstract   Background: Iatrogenic airway injury after endotracheal intubation and tracheotomy   remains a serious clinical problem. In this study we reviewed post-intubation and traumatic tracheal stenosis in 47 patients with a special attention to the cause, hense surgical treatment of the stenosis was performed and the results compared with the literatures.   Methods: Since February 1995 th...

STUDY OBJECTIVE To compare the surgical findings of tracheal stenosis caused by percutaneous tracheostomy (PCT) and surgical tracheostomy (SGT). DESIGN AND SETTING A combined prospective (from 2001 to 2003) and retrospective (from 1993 to 2001) observational study of the patients undergoing tracheal resection and reconstruction for treatment of tracheal stenosis following PCT or SGT in a nati...

BACKGROUND AND OBJECTIVES Injuries of tracheal mucosa in contact with tracheal tube cuff is a function of cuff pressure and exposure time. This study aimed at analyzing injuries of tracheal mucosa in contact with tracheal tube cuff inflated to reach "seal" pressure or limit 25 cmH2O pressure, below critical 30 cmH2O, to prevent tracheal damage. METHODS This study involved 16 dogs submitted to...

BACKGROUND Storage mites are a source of aeroallergens that affect patients with allergic rhinitis and asthma. Tyrophagus putrescentiae is a causative factor of airway hypersensitivity, but the mechanisms and pathogenesis of Tputrescentiae-induced allergy are not well understood. OBJECTIVE This study aimed to develop a murine model of T putrescentiae-induced allergic asthma. METHODS Immune ...

BACKGROUND Tracheal necrosis is a severe complication of total pharyngolaryngectomy (TPL). The purpose of this retrospective study was to identify risk factors for tracheal necrosis after TPL. METHODS We performed a retrospective chart review of 177 patients who had undergone TPL. The preoperative, operative, and postoperative variables were examined, and possible risk factors for tracheal ne...

Difficulty of tracheal intubation is caused by many reasons and among them tracheal rupture is an infrequent factor. Tracheal rupture leads to higher mortality and poorer prognosis especial for closed tracheal rupture which is hard to early diagnose and is generally fatal. We described a case of a 34-year-old narcose man after a car accident that accepted twice unsuccessful tracheal intubation ...

BACKGROUND The effects of dexmedetomidine on the propofol-sparing effect and intraoperative hemodynamics during remifentanil-based propofol-supplemented anesthesia have not been well investigated. METHODS Twenty patients undergoing breast surgery were randomly allocated to receive dexmedetomidine (group DEX) or placebo (group C). In the DEX group, dexmedetomidine was loaded (1 µg/kg) before a...

STUDY OBJECTIVE Previous studies suggest improved patient outcomes for providers who perform high volumes of complex medical procedures. Out-of-hospital tracheal intubation is a difficult procedure. We seek to determine the association between rescuer procedural experience and patient survival after out-of-hospital tracheal intubation. METHODS We analyzed probabilistically linked Pennsylvania...

The incidence of myocardial ischaemia during tracheal intubation and extubation was compared using ambulatory ECG monitoring in 60 patients undergoing a variety of different surgical operations. Seven patients had myocardial ischaemia after tracheal intubation and seven patients during tracheal extubation. The patients who developed myocardial ischaemia during tracheal extubation had significan...

OBJECTIVES To evaluate the histological changes of tracheal cartilage and epithelium caused by tracheal occlusion at different gestational ages in a fetal rat model. METHODS Rat fetuses were divided into two groups: a) External control, composed of non-operated rats, and b) Interventional group, composed of rats operated upon on gestational day 18.5 (term = 22 days), divided into triads: 1) T...
