Retrosternal Percutaneous Tracheostomy: An Approach for Predictably Impossible Classic Tracheostomy
Percutaneous tracheostomy is a routine procedure in intensive care
units. In cases of very low position of the larynx, cervical spine
deformation, morbid obesity, or neck tumor, performance of the
classic tracheostomy is inapplicable. Retrosternal approach to
tracheostomy in such 20 patients is herein reported. After
preoperative neck computerized tomography to define the neck
anatomy, a small suprasternal incision followed by a short
retrosternal tissue dissection to expose the trachea was done; the
trachea was then catheterized at the level of the 2nd ring in the
usual tracheostomy manner. The immediate and late (≥6 months) outcomes were similar to that of the standard tracheostomy. Thus,
percutaneous retrosternal tracheostomy is safe in patients with
abnormal positioning of the trachea or neck constitution. It is a
bedside applicable technique, that, however, requires caution to
avoid hazardous vascular complications
Anesthetic consideration for patients with severe tracheal obstruction caused by thyroid cancer -A report of 2 cases-
To achieve safe airway management, it is essential first to predict whether there will be difficulties in intubating or ventilating the patient's airway. An enlarged thyroid mass can produce a tracheal obstruction by compression or intraluminal invasion or both. We report two patients with thyroid cancer that obstructed the trachea by compression or invasion. There was no difficulty in endotracheal intubation of the patients with marked thyroid enlargement or in securing passage of the endotracheal tube through the compressed or narrowed portion of the trachea
Ischemia of the lung causes extensive long-term pulmonary injury: an experimental study
Background: Lung ischemia-reperfusion injury (LIRI) is suggested to be a major risk factor for development of primary acute graft failure (PAGF) following lung transplantation, although other factors have been found to interplay with LIRI. The question whether LIRI exclusively results in PAGF seems difficult to answer, which is partly due to the lack of a long-term experimental LIRI model, in which PAGF changes can be studied. In addition, the long-term effects of LIRI are unclear and a detailed description of the immunological changes over time after LIRI is missing. Therefore our purpose was to establish a long-term experimental model of LIRI, and to study the impact of LIRI on the development of PAGF, using a broad spectrum of LIRI parameters including leukocyte kinetics.Methods: Male Sprague-Dawley rats (n = 135) were subjected to 120 minutes of left lung warm ischemia or were sham-operated. A third group served as healthy controls. Animals were sacrificed 1, 3, 7, 30 or 90 days after surgery.
