Comparison of Aintree and Fastrach techniques for low-skill fibreoptic intubation in patients at risk of secondary cervical injury

Abstract

Fibreoptic intubation using the Aintree system was more successful than the Fastrach technique in our population of patients in a neutral position wearing a soft cervical collar. The differences in the time to successful intubation between the two groups are unlikely to be clinically relevant.

Fibreoptic‐guided tracheal intubation through i‐gel® and LMA® ProtectorTM supraglottic airway devices ‐ a randomised comparison

“…We found no significant difference in time to fibreoptic‐guided tracheal intubation between the two groups. These findings compare favourably with studies looking at fibreoptic‐guided tracheal intubation via other SADs (including the i‐gel) .…”

Conversion of I-gel to definitive airway in a cervical immobilized manikin: Aintree intubation catheter vs long endotracheal tube

“…The iLMA has a stiff angled shank and a wide internal diameter for ETT insertion, as does the LMA Fastrach™. It is also shorter than other LMAs and has a stabiliser rod that pushes the ETT [14]. A previous study compared the efficacy of the iLMA with that of a combination of the AIC and classic LMA (cLMA) during insertion of a 7.0 mm ID ETT.…”

“…A previous study compared the efficacy of the iLMA with that of a combination of the AIC and classic LMA (cLMA) during insertion of a 7.0 mm ID ETT. They reported that not only was iLMA insertion more difficult than cLMA, but it also resulted in a poor glottis view in 26% of cases, even after insertion [14]. Furthermore, the iLMA is less widely available than the cLMA [9] and has a steeper learning curve, hampering its routine use [18] Thus, the iLMA does not appear to improve upon the combination of the AIC and cLMA [14,19].…”

“…After each procedure, the participants rated intubation difficulty using a numeric scale from 1 (extremely easy) to 10 (extremely difficult). Each participant also recorded their preference between the two methods and the reason for their preference [14].…”

“…Ainsi, en plus de permettre une intubation primaire, l'Aintree peut être utilisé pour l'échange de TET tout en étant positionné par fibroscopie. Comme il s'adapte au travers d'un dispositif supra-glottique, il peut également servir de guide à l'intubation trachéale tout en administrant de l'oxygène au patient[30][31][32]. Son développement a été intimement lié à la volonté de permettre une intubation assisté par la fibre optique, tout en gardant à tout moment un contrôle de la voie aérienne.…”
