Evaluation of the Accuracy and Reliability of the Percentage of Glottic Opening Score - Trial NCT04244292

Timeline & Enrollment

Primary Outcome

Percentile of glottic opening

Summary

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
