Naso‐tracheal jet ventilation for micro‐laryngeal procedures

Anaesthesia for Laryngoscopy: A Technique Using the Nuffield Anaesthetic Ventilator

“…The advantages of jet ventilation during microlaryngeal surgery have been discussed by Tobias, Nassar and Richards (1977) and the present study confirmed the findings of those and other authors (Smith, Babinski and Petruscak, 1974;Poling, Wolfson and Siker, 1975). The ventilator control module will deliver a gas flow of up to 60 litre min" 1 at a pressure of 250 kPa and it can be driven by most gases or mixtures of gases in clinical use.…”

“…The ventilator control module will deliver a gas flow of up to 60 litre min" 1 at a pressure of 250 kPa and it can be driven by most gases or mixtures of gases in clinical use. Although these flow rates and driving pressures are less than those reported in some studies (Poling, Wolfson and Siker, 1975;Tobias, Nassar and Richards, 1977) the ventilating capacity of the system (as assessed by arterial blood-gas analysis) was adequate for all the patients in this study. However, jet ventilation systems behave as pressure generators (Pybus and Adams, 1978) and The frequency of awareness during laryngoscopy when anaesthesia is maintained by i.v.…”

Complications of Venturi Jet Ventilation During Microlaryngeal Surgery

“…Careful selection of jet size and pressure gauge to suit individual patients. 5. The smaller cross-sectional diameter of the infant's trachea poten¬ tiates to higher intratracheal pres¬ sures with its sequelae.…”

Two Cases of Barotrauma Associated With Transtracheal Jet Ventilation

“…It has been advocated in situations where immediate tracheal intubation may not be possible [4] and in anaesthesia for direct laryngoscopy [5]. Tobias, Nassar and Richards reported a method of nasotracheal jet ventilation for microlaryngeal procedures using a Sanders injector [6]. TJie following year, Pybus, O'Connor and Henville devised a catheter technique using the control module of the Nuffield Anaesthetic Ventilator [7].…”
