To the Editor:—

I read with interest Dr. Feingold's technique for using the LTA® cannula (Abbott Laboratories, North Chicago, IL) to facilitate a difficult intubation. 1What I do not understand is, after the cannula is through the vocal cords and in the trachea, why not use it as a stylet guide over which the endotracheal tube is advanced into the trachea? We originally described this technique in 1977. 2Cahen independently described the same technique in 1991. 3Others 4have reported using our technique many times to “save the day.”
