AbstractAirway management in patients presenting with severe airway obstruction can present a challenge to the anaesthetist, as conventional difficult airway pathways are often inappropriate. The use of a transtracheal jet cannula is an alternative means of airway securement, but lack of familiarity has limited its use in general tertiary hospitals. We report a retrospective audit of the use of transtracheal jet ventilation in a general tertiary healthcare centre over the past seven years, with a total of 50 patients with severe airway compromise undergoing pharyngolaryngeal surgery. Transtracheal jet ventilation was successful in 98% of patients, and was the definitive means of airway management in 43 cases. In six cases, the technique was a useful temporising measure while the airway was secured by other means. Minor complications occurred in 12% of patients. No major morbidities or mortalities were recorded. We conclude that transtracheal jet ventilation for high-risk pharyngolaryngeal surgery can be performed using a high frequency jet ventilator, with a high rate of success and only minor complications. Cannulation of the trachea below the cricothyroid membrane is feasible but more challenging. Low-flow apnoeic oxygenation through the transtracheal jet ventilation cannula maintains oxygenation during initial surgical airway manipulation.
