Proper preparation of the Trachlight~(TM) and endotracheal tube to facilitate intubation

摘要

While the Trachlight~(TM) (Laerdal Medical Corp., Wappingers Falls, NY, USA) has been shown to be an effective and safe device for tracheal intubation, occasionally following the retraction of the internal stiff stylet, the tip of the endotracheal tube (ETT) seems to get "hung up" and cannot be readily advanced into the trachea. This is likely due to the fact that when an ETT is loaded along its natural curvature onto the Trachlight~(TM), the tip of the ETT has a tendency to bend anteriorly upon retraction of the internal stiff stylet (Figure A). With this anterior bending, the tip of the ETT may be trapped or pushed against the anterior aspect of the cricoid ring or tracheal cartilaginous rings, making it difficult to further advance the ETT into the trachea. We would like to report two modified preparations of the Trachlight~(TM) and ETT which may help to overcome this difficulty.
