A New Tube for Microlaryngeal Surgery

Abstract

A technique of anaesthesia for micro laryngeal surgery is described lItilizing a new catheter and the venturi jet injector. Access and exposure for the surgeon are excellent and the laser can be used without special precalltions. The central position and lack of movement of the distal end of the tube in the trachea prevent the potential complication of rupture of the trachea or of a bronchus.

Anaesthesia for microlaryngeal and laser laryngeal surgery: impact of subglottic jet ventilation

“…Benjamin and Gronow developed a technique of anaesthesia for microlaryngeal surgery using a subglottic jet ventilation catheter and a Venturi jet injector. 8 Tubes for subglottic jet ventilation were subsequently developed by Hunsaker, and at our own institution by Bridger and Maver. 9,10 Over the last 20 years, subglottic jet ventilation tubes have improved.…”

“…Komesaroff and McKie's work highlighted the importance of tracheal pressure measurements, which were recorded via a fine polyethylene catheter attached to the outer wall of the bronchoscope. Benjamin and Gronow developed a technique of anaesthesia for microlaryngeal surgery using a subglottic jet ventilation catheter and a Venturi jet injector 8 . Tubes for subglottic jet ventilation were subsequently developed by Hunsaker, and at our own institution by Bridger and Maver 9 , 10…”

“…Over the last 20 years, subglottic jet ventilation tubes have improved. The current Prince of Wales Hospital jet ventilation tube is a fourth generation device; the previous three generations include the Hunsaker Mon-Jet, the Ben Jet and the first generation Prince of Wales Hospital tube 8 – 12 …”

Recurrent respiratory papillomatosis: A 10 year study

“…Intubation with a small diameter conventional endotracheal tube was used occasionally in cases where obstruction was severe; temporary intubation was necessary to stabilize the anaesthesia. In adults, a relaxant technique with jet ventilation using a 2.8 mm external diameter tube in the lumen of the midtrachea was used (Benjamin and Gronow, 1979). This tube is suitable for laser surgery as it can be easily positioned in the anterior or posterior larynx so that the laser beam can be used at a safe distance from the tube (Fig.…”

THRIVE: a different approach in microlaryngeal surgeries

“…

Micro-laryngeal surgeries (MLS) are typically performed under general anaesthesia either by employing a microlaryngeal tube or by providing apnoeic oxygenation without endotracheal intubation using high frequency jet ventilation. [1][2][3] Though the micro-laryngeal tube impedes surgical access less than conventional endotracheal tubes (ETT), it does not provide an unobstructed view of the larynx.Jet ventilation used as alternative to endotracheal anaesthesia, but it may cause movement of vocal cords, barotrauma and tumour implantation in trachea. 4 THRIVE is a technique that uses rapidly insufflate, heated, humidified gases administered via high flow nasal cannula (HFNC) to achieve apnoeic oxygenation.
