Current classifications of the laryngeal view during laryngoscopy are criticized for being
subjective.
The modified CL classification is criticized as it does not predict difficult intubation and
especially grade 2 is operator dependent and partial view is not well defined. The numerical
expression of the percentage of the glottic aperture (POGO = percentile of glottic opening)
is another score. In this score, A POGO score of 100% accounts for full visualization of the
larynx starting from anterior commissure to the posterior cartilage, while 0% indicated a
complete absence of glottic opening. Previous validation studies reported on the reliability
of POGO; however, accuracy was not evaluated.
The use of a standard and effective classification method will facilitate and accelerate
communication between anesthetists in difficult life-threatening situations such as difficult
airway / difficult intubation / difficult ventilation and contribute to patient safety. The
use of common terminology can also facilitate the evaluation of the performance of intubation
tools. The aim of this study was to evaluate the accuracy and intra and inter rater
reliability of the POGO score
