Posterior tracheal wall rupture following uneventful general endotracheal anaesthesia

Studies on the effects of air ions on the functional efficiency of the extirpated tracheal strip have been extended to the trachea of the living rabbit, rat, and mouse. Animals exposed to high mobility (+) air ions administered via a tracheotomy aperture displayed: (a) Decreased ciliary activity. (b) Decline in mucus flow rate, sometimes reversed by prolonged exposure to (+) ions; a frequent drop in the volume of mucous secretion. (c) Contraction of the membranous posterior tracheal wall. (d) Increased vulnerability to trauma of cilia and mucosal blood vessels. Similar treatment with (-) air ions reversed (+) ion effects on ciliary activity, mucus flow, contraction of the tracheal smooth muscle. Continued (-) ion treatment raised the ciliary rate (invariably) and the mucus flow rate (often) above their initial levels. (+) Air ions administered to unoperated resting mice and rats increased the respiratory rate; (-) ions reversed this effect. Long exposure of unoperated ambulatory mice to (+) air ions produced: (a) Decreased ciliary activity. (b) No clear cut effect on mucus flow. (c) Contraction of the posterior tracheal wall. (d) Increased vulnerability of the mucosa to trauma. (-) Air ions increased ciliary activity but had no clear-cut effect on the mucus flow rate.

Tracheal Puncture

The objective of this study was to investigate a new technique for tracheal puncture during percutaneous dilatational tracheotomy (PDT). A new invention, known as SafeTrach, was used: this instrument allows exact localization of the puncture site with built-in protection of the posterior tracheal wall. Surgery was performed on 17 patients with this technique, and our experience is described in this report. The results showed that this new technique minimizes known risk factors compared with existing PDT techniques, including patients with disadvantageous anatomy.

Posterior Tracheal Wall

Objective: To describe the retrograde removal of a tracheoesophageal (TE) prosthesis embedded in the common wall between the trachea and esophagus with preservation of the original tracheoesophageal puncture (TEP) tract with subsequent placement of new tracheoesophageal prosthesis for voice restoration. Methods: The Blom-Singer TEP Set (InHealth Technologies, Carpinteria, CA) was used to facilitate this procedure. The coated wire leader cable was threaded through the small opening in the posterior tracheal wall and into the lumen of the old TE prosthesis. The wire was pulled through the mouth in retrograde fashion - bringing the old TE prosthesis out with it and dilating the existing TEP tract. A new prosthesis was then placed over the end of the wire and returned through the stoma, delivering the prosthesis through the TE tract and into the stoma. Results: Safe, voice restoration with avoidance of need for multiple procedures. Conclusion: Removal of an embedded prosthesis and simultaneous replacement of a new prosthesis was safely and efficiently achieved using a retrograde technique which maintained the patency of the prior TE tract and restored voice.
