ABSTRACTIntroduction: Airway management in surgical patients is one of the most demanding tasks for the anesthesiologist, since up to 30% of anesthetic deaths are attributed to an unidentified difficult airway. Therefore, several different scales have been developed for assessment, which help us anticipate difficulties in perioperative airway management, and thus reduce morbidity and mortality. Objective: Determine the relationship between mask ventilation (Han Scale) and laryngoscopic view (Cormack-Lehane scale) in patients requiring endotracheal intubation. Material and methods: Observational, transversal and prospective study on 100 patients at Hospital Ángeles Clínica Londres, who underwent surgery and required both mask ventilation, as well as endotracheal intubation. A statistical model was fitted, in order to measure the degree of confidence when forecasting Cormack-Lehane degree with Han scale. Results: For certain values of Cormack-Lehane, up to 83% degree of confidence for predictions using the Han scale was quantified. Conclusions: Evidence suggests a high degree of correlation between both scales.
