L'intubation oro-trachéale par voie rétrograde

Evaluation of intubating conditions using stylet by conventional through-tube technique and through Murphy′s eye in patients with high Mallampati scores

“…[5] The use of Murphy's eye has earlier been described in a case of retrograde intubation by threading the guide wire through the Murphy's eye and thus intubation was successfully done. [67] Though the use of Murphy's eye with the bougie has been described in a case of difficult intubation but the use of stylet through Murphy's eye in difficult airway and its efficacy in cases of difficult intubation has not been tested in literature till date. [8] In this study, the use of the Murphy's eye for passing stylet during difficult airway maneuver was done in 30 patients with Mallampatti class III.…”

Retrograde tracheal intubation: beyond fibreoptic endotracheal intubation

“…Puncture of the infracricoid membrane instead of the cricothyroid membrane seems to increase the success rate since it facilitates the passage of the tracheal tube within the larynx (17,18). Another common modification is introduction of the guide into a rigid tube, pushing the tracheal tube down over it, to avoid dislodgement of the endotracheal tube tip into the arytenoid cartilages, the vocal cords, the piriform sinus, or the vallecula (19)(20)(21).…”

“…This can prevent entrapment of the tip in the epiglottis or the arytenoids (17). Pulling techniques, either by creating a loop around the side eye or simply knotting an epidural catheter with the Murphy's eye, apparently increase the success rate of RTI (22,23).…”
