We discuss a case of difficult extubation, due to inadequate deflation of the tracheal tube cuff, despite collapse of the pilot balloon, on its aspiration. This was caused by inadvertent kinking of the pilot balloon tubing due to inappropriate tape fixation of the endotracheal tube.

Background and aims: To compare intubating conditions and cardiovascular changes followinduction of anesthesia and tracheal intubation in patients receiving either lidocaine-remifentanilpropofolor lidocaine-remifentanil-sevoflurane prior to induction.Methods and materials: In a randomized, double-blind study 75 healthy children patientswere assigned to one of two groups: lidocaine 1.5 mg·kg-1, ...

Crocin, a component of saffron, showed hypotensive which is perhaps due to vascular smooth muscle relaxant effect. The relaxant effects of saffron on tracheal smooth muscle also could be due to its constituent, crocin. In the present study, the relaxant effects of crocin and its possible mechanisms on rat tracheal smooth muscle were investigated. The relaxant effects of three cumulative concent...

Drosophila tracheal terminal branches are plastic and have the capacity to sprout-out projections towards oxygen-starved areas, in a process analogous to mammalian angiogenesis. It was previously shown that this sprouting response involves the upregulation of the FGF homolog Branchless in hypoxic tissues, which binds its receptor Breathless on tracheal cells, thereby attracting the outgrowth of...

BACKGROUND Tracheal stenosis or tracheal injury is a troublesome disease. Traditional temporary tracheostomy and reconstruction can resolve some problems. However other problems such as subglottic stenosis and supracarinal stenosis, cannot be resolved by simple tracheostomy. The silicone tracheal T-tube presents a substitute for stent of this complicated disease. METHODS Eleven patients with ...

a 3 month- old boy was admitted with recurrent severe respiratory distress and refractory to therapeutic options. patient underwent a helical multidetector ct examination. axial, coronal and three- dimensional imaging, revealed tracheal bronchus, stenosis, diverticulum and bronchiectasis. in this situation, ct scanning, perfectly 3d imaging is recommend for rule out congenital tracheobronchial ...

Inhaled sodium metabisulphite (MBS) causes bronchoconstriction, cough and microvascular leakage. We have studied its effects on tracheal blood flow, potential difference (PD) and the permeability from tracheal lumen to venous blood of a low molecular weight hydrophilic tracer, 99mtechnetium-labelled diethylenetriamine penta-acetic acid (99mTc-DTPA) in anaesthetized sheep. Flow was measured in t...

OBJECTIVES/HYPOTHESIS In this study, a bioengineered trachea composed of autologous chondrocytes was developed, and its effect on cartilaginous regeneration was evaluated by implantation into tracheal defects in rabbits. STUDY DESIGN Prospective controlled trial in an animal model. METHODS The tracheal prosthesis used in this study was composed of polypropylene (the frame) and collagen spon...

The volume of a tracheal system influences breath-holding capacity and provides an index of an insect's investment in its respiratory system. Here, we describe a new, generally applicable method to measure tracheal volume that enables repeatable determinations on live animals. Animals are isolated in a closed chamber of a known volume and equilibrated with a helium:oxygen gas mixture. The chamb...
