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 were...

Conventional tracheostomies have been used for many years to deliver oxygen with the patient breathing spontaneously or in conjunction with positive pressure ventilators. The insertion of a transtracheal catheter specifically to deliver oxygen, however, dates only from Heimlich's studies published in 1982.' He showed that in dogs and man a normal oxygen saturation could be maintained by the del...

OBJECTIVE To assess the safety and efficacy of percutaneous transtracheal jet ventilation (PTJV) in the management of the difficult airway. DESIGN Retrospective case series. SETTING Academic, tertiary care medical center. PATIENTS Forty-three consecutive PTJV procedures performed on 33 patients with anticipated airway difficulty undergoing direct laryngoscopy for diagnosis and/or treatmen...

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.

The role of mycobacteria in the cavitation of large pneumoconiotic masses is well established. In other cases softness is attributed to an ischaemic or aseptic necrosis. Five cases are described in which cavitation of the pulmonary masses was caused by anaerobic bacteria, confirmed by the growth of such bacterial in cultures after transtracheal or transpleural puncture. Repeated cultures for my...

Bronchial secretions from 21 patients with moderate to severe chest infections were obtained by transtracheal aspiration. Six seriously ill patients showed greatly increased levels of amylase activity in the bronchial secretions compared with those found in the 15 less ill patients. This amylase was almost certainly derived from oropharyngeal contents and its presence suggests that aspiration m...

Laryngospasm is reversible spasm of vocal cords that common in patients who are undergoing upper airway related surgeries under general anaesthesia. It occurs mostly following extubation; requires immediate management and if these left untreated rapid decrease saturation with bradycardia may take place. Lignocaine considered effective prevention laryngospasm by both topical intravenous route. a...

A 50 percent or greater savings in oxygen usage and aesthetic benefits leading to increased compliance are reasons for increasing use of the transtracheal catheter for administration of home supplemental oxygen. Minor complications of the procedure are common and include catheter dislodgement, bronchospasm, subcutaneous emphysema, bleeding at the catheter site, as well as hemoptysis and wound i...

This prospective, blinded, observational, efficacy study is one of the first to evaluate ultrasound in detecting esophageal intubation, a significant source of morbidity and mortality. We utilized a convenience sample of patients undergoing elective surgery during July 2004 in an urban teaching hospital. Trained Emergency Physician sonographers performed transtracheal ultrasounds of intubations...
