To the Editor:
I read with interest a paper written by Suzuki et al. [1]. In that article, they evaluated the advantage of Parker Flex-tip Tube™ in endotracheal intubation using AirwayScope™ videolaryngoscope (AWS; Hoya, Tokyo, Japan) in patients without difficulty. I agree with the authors’ conclusion that the use of the Parker tube in combination with the AWS is an optional technique on some occasions. However, there is no evidence to the advantage of their means of inserting the blade tip of the AWS behind the epiglottis in patients with difficulty. Indeed, it is crucial to examine such an advantage only in patients with unsuccessful endotracheal intubation using the AWS at the first attempt [2]. Therefore, we must await additional studies to confirm the conclusion drawn by Suzuki et al.
