Objective: The use of a T-tube to manage complex laryngotracheal lesions, such as tracheal stenosis, tracheomalacia and tracheal injury, has previously been reported by other surgeons in the past. However, further validation of clinical details, including operative management and postoperative care, is needed. Methods: From January 1991 to May 2000, 53 patients, including 24 with post-tracheost...

Exogenous hydrogen peroxide (H2O2) causes airway epithelial damage in vitro. We have studied the effects of luminal H2O2 in the sheep trachea in vivo on tracheal permeability to low-molecular-weight hydrophilic (technetium-99m-labeled diethylenetriamine pentaacetic acid; 99mTc-DTPA) and lipophilic ([14C]antipyrine; [14C]AP) tracers and on the tracheal vascular response to luminal capsaicin, whi...

introduction: tracheal stenosis is normally caused by trauma, infection, benign and malignant tumors, prolonged intubation or tracheostomy. the best treatment for tracheal stenosis is resection and anastomosis of trachea. yet the major surgical complication of tracheal surgery is postoperative stenosis. the goal of this paper is to study the result of tracheal stenting as a replacement therapy ...

The object of this study was to investigate how changes in the contractile state of smooth muscle would modify oscillatory mechanics of tracheal muscle and lung parenchyma during agonist challenge. Guinea pig tracheal and parenchymal lung strips were suspended in an organ bath. Measurements of length (L) and tension (T) were recorded during sinusoidal oscillations under baseline conditions and ...

The Montgomery T-tube poses a challenge to anesthesiologists because of loss of anesthetic gases through the open proximal end of the vertical limb and lack of standard anesthesia circuit connectors. Here, we present a case of a 25-year-old woman with a reported history of accidental strangulation 18 months previously. The patient had a metallic tracheostomy tube in situ due to the development ...

© 2002 Association médicale canadienne T keys to successful treatment of tracheal tears after endotracheal intubation are early recognition, control of airway, antibiotic therapy and surgical repair. Surgical approaches to the repair of iatrogenic membranous tracheal injuries depend on the extent and location of the tear. Tears of the upper two-thirds can usually be repaired through a cervical ...

Intracellular Ca(2+) transient is crucial in initiating the differentiation of mesenchymal cells into chondrocytes, but whether voltage-gated Ca(2+) channels are involved remains uncertain. Here, we show that the T-type voltage-gated Ca(2+) channel Cav3.2 is essential for tracheal chondrogenesis. Mice lacking this channel (Cav3.2(-/-)) show congenital tracheal stenosis because of incomplete for...
