Excerpt
Dr. Hung reported the use of a lighted stylet for tracheal intubation through the laryngeal mask [1]. He stated that "although Asai and Latto [2] suggested the use of a lightwand to assist tracheal intubation via the LMA, they did not place the tracheal tube in the patients" [2]. However, we did assess the efficacy of this technique after obtaining a formal approval from the local ethics committee and reported it separately [3], before the submission of Dr. Hung's correspondence letter [1].
In our report, we planned to compare the success rate of tracheal intubation through the laryngeal mask with and without the use of a lighted stylet (Trachlight; Laerdal Medical Corporation, Armonk, NY) [3], which is the same type of device that Dr. Hung used [1]. However, we abandoned the study after enrolling 12 patients because the trachea was intubated only in 1 of 6 patients at the first attempt even when the lighted stylet was used. This result is discrepant from those obtained by Dr. Hung, whose success rate using this technique was 8 of 10 patients [1]. We have reported some disadvantages of the use of the lighted stylet in this technique [3].
