BACKGROUND Emergency ventilation through a small-bore transtracheal catheter can be lifesaving in a 'cannot intubate, cannot ventilate' situation. Ejectors, capable of creating suction by the Bernoulli principle, have been proposed to facilitate expiration through small-bore catheters. In this bench study, we compared a novel, purpose-built ventilation ejector (DE 5) with a previously proposed,...

Benign esophagorespiratory fistula is a rare but often lethal affection and difficult to cure. Possible treatments are surgery or esophageal stenting but may fail and cause respiratory failure. Two patients with spontaneous esophagorespiratory fistula after chemoradiotherapy for an esophageal malignancy were both treated by esophageal exclusion but esophageal stent were left in place. The esoph...

The effect of transtracheal oxygen administration by means of a 9-French (2.7 mm) percutaneous catheter was assessed in five patients with severe obstructive sleep apnea. We hypothesized that the delivery of oxygen below the site of airway obstruction should reduce the arterial oxygen desaturation during apneas and hypopneas, thereby increasing respiratory stability. Standard sleep and respirat...

Transtracheal oxygen (TTO) delivery for patients with chronic hypoxemia has been used increasingly since its introduction in 1982. Most complications have been relatively minor and usually occur in conjunction with catheter placement. This report describes two patients with long-term catheter use who developed increasing respiratory failure and cor pulmonale, at least in part, due to a large tr...

BACKGROUND Anaesthesia for laryngeal surgery may be complex and associated with complications. METHODS We conducted a national survey exploring airway management and ventilation during elective laryngeal surgery, focusing primarily on injector and jet ventilation (i.e. high-pressure source ventilation: HPSV). RESULTS Responses were received from 229 centres (75%). Several hospitals reported...

BACKGROUND Transtracheal access and subsequent jet ventilation are among the last options in a 'cannot intubate-cannot oxygenate' scenario. These interventions may lead to hypercapnia, barotrauma, and haemodynamic failure in the event of an obstructed upper airway. The aim of the present study was to evaluate the efficacy and the haemodynamic effects of the Ventrain, a manually operated ventila...

Successful natural orifice transluminal endoscopic surgery (NOTES) procedures have been reported in animal studies. However, very little is known about the optimal approach for the application of these surgeries in the thoracic cavity. This study presents the feasibility of transtracheal evaluation of pleural cavity in a canine model using the NOTES technique.
