background: when we perform surgery in utero, lungs have an appropriate time to decrease magnitude of hypoplasia, with surgery in uterus. methods: six time-dated single-fetus ewes were selected to induce diaphragmatic hernia. fetal lambs were divided proportionally into 2 groups, namely group 1, diaphragmatic hernia and tracheal ligation (tl group), and group 2, diaphragmatic hernia only (nl gr...
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...
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...
The purpose of this study was the effect of epithelium damage on mechanical responses of airway smooth muscles under different resting tension. We performed acetylcholine (ACh) (10(-5) M)-induced contraction on tracheal strips from 30 rabbits in five groups (0.5, 1, 1.5, 2 and 2.5 g) before and after epithelium removal. At low resting tension (0.5-1.5 g), the epithelium removal decreased the AC...
Objective(s) Two new adjuvants from natural animal lipids (G2) and bacterial polysaccharide extracts (PC) were previously prepared by our group and showed a reduction in tracheal responsiveness. The aim of this study was to evaluate the preventive effect of recently introduced natural products (G2 and PC) on the development of asthma. Materials and Methods Asthma was induced using a standard...

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...
