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 throug...

The Montgomery T-tube is a valuable tracheal stent that provides a functional airway while supporting the tracheal mucosa. It is used in benign and malignant tracheal diseases and provides symptomatic relief to the majority of the patients. T-tubes are simple to insert and rarely cause serious complications. The use of T-tubes continues to gain popularity with the increasing incidence of benign...

Background Traditionally, non-cuffed tubes have been used for tracheal intubation of children under eleven years of age. The evidence is now strongly supportive of cuffed tubes in this population. Objectives We aimed to ascertain the patterns of tracheal tube usage in paediatric anaesthesia in Ireland. Materials and methods A self-structured questionnaire was distributed at anaesthesia conferen...

The tracheal (respiratory) system of Drosophila melanogaster is a branched network of epithelial tubes that ramifies throughout the body and transports oxygen to the tissues. It forms by a series of sequential branching events in each hemisegment from T2 to A8. Here we present a cellular and initial genetic analysis of the branching process. We show that although branching is sequential it is n...

The addition of tracheal tubes to the respiratory system contributes an extra mechanical burden in terms of pressure necessary to overcome its own resistance. On the basis of experimental data from the literature and on a previously reported mathematical model of the inspirogram, we wished to study predictions of pressures, volume, flow and work of breathing during the use of tracheal tubes. Th...
