A classification method describing the larynx appearance during laryngoscopy accepted by all
anesthetists has not been defined yet. In one study, it was shown that anesthetists mis
classed the glottis image by 50%. The most commonly used classification method is the Cormack
Lehane (CL) classification. This classification classifies the larynx appearance during
direct laryngoscopy form 1 to 4. 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.
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.
