A new transtracheal catheter for ventilation and resuscitation.

Oxygenation and ventilation during cardiopulmonary resuscitation utilizing continuous oxygen delivery via a modified pharyngeal-tracheal lumened airway.

Use of continuous transtracheal oxygen delivery systems combined with rhythmic chest compressions can provide excellent oxygenation and ventilation during cardiopulmonary resuscitation. However, occasional displacement of the transtracheal catheter results in life-threatening pneumomediastinal complications. We investigated using the pharyngeal lumen of a pharyngeal-tracheal lumened airway (PtL...

Transtracheal high frequency jet ventilation for endoscopic airway surgery: a multicentre study.

Serious complications during high frequency jet ventilation (HFJV) are rare and have been documented in animals and in case reports or short series of patients with a difficult airway. We report complications of transtracheal HFFJV in a prospective multicentre study of 643 patients having laryngoscopy or laryngeal laser surgery. A transtracheal catheter could not be inserted in two patients (0....

Transtracheal catheter ventilation: clinical experience in 36 patients.

Aprospective randomized study comparing respiratory efficacy of percutaneous transtracheal and endotracheal, low-frequency jet ventilation during microlaryngeal surgery

 Abstract Background: Transtracheal jet ventilation is an alternative ventilatory approach in airway surgery. The purpose of this study was to compare respiratory efficacy of percutaneous transtracheal with endotracheal, low frequency jet ventilation during microlaryngeal surgery. Methods: Ninety ASA class I-II patients aged between 16 and 70 years undergoing elective microlaryngeal surgery wer...

Ventilation through a small-bore catheter: optimizing expiratory ventilation assistance.

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,...
