High frequency jet ventilation for microlaryngeal laser surgery

Abstract

SummaryThe use ? f a triple lumen central venous catheter, which can be shielded from laser irradiation by metal tape, as a conduit for high ,frequency jet ventilation in six children, is described. The problems of anaesthesia for laryngeal laser surgery and the advantages of the technique described in this paper are discussed.

Difficult airways: a reliable “Plan B”

“…3 Patel used a commercially available 12-G venous access device [inner diameter (ID) 2.8 mm)], or a special transtracheal catheter (6 F, ID 2 mm), and expressed concern that regular catheters are thin-walled and kink easily. The use of a CVC to establish translaryngeal jet ventilation was first described in children, 4 and the use of the CVC has subsequently been described to establish transtracheal jet ventilation. 5 The CVC is less likely to kink or become displaced, and is easily secured.…”

A tubeless anaesthetic technique for paediatric laryngeal laser surgery

“…The risk of barometric damage to the distal airways has been minimised by high frequency jet ventilation via a triple lumen catheter. Dhara et al [13] used ventilation applied by the distal lumen, the middle attached to the airway pressure measurement port of the ventilator, and the proximal lumen used to monitor end-tidal carbon dioxide tension. The third lumen was only of use in patients aged over 9 years as the opening of the proximal lumen had to be occluded in smaller patients because, it lay too close to the glottis.…”

Double‐lumen central venous catheter for pediatric airway management in laryngeal papillomatosis: an old technique reborn?

“…I would refer both sets of authors to the article published 22 years ago in Anaesthesia which described the use of a foil wrapped triple‐lumen CVC for the delivery of high‐frequency jet ventilation in microlaryngeal laser surgery in children as young as 6‐month old.…”
