Diagnostic value of the percentage of glottic opening score for classifying videolaryngoscopy in children: a prospective validation study
Listen to this summary
The authors aimed to evaluate the diagnostic value of the percentage of glottic opening (POGO) score in classifying difficult videolaryngoscopic tracheal intubation in children, comparing it to subjective visual analogue scale (VAS) ratings. The study found that the POGO score demonstrated significantly poorer diagnostic performance and inter-rater reliability compared to VAS ratings, indicating that it is not a reliable tool for predicting difficult intubation in this population.
