Relación de la escala de Han comparada con la de Cormack en el manejo de la vía aérea en anestesia general de pacientes mayores de 18 años en el Hospital Vicente Corral Moscoso, Cuenca 2019

Abstract

Background: proper airway management during general anesthesia is vital, even more if there is any difficulty. The scales help to predict a difficult airway. Objective: to determine the relationship of the Han scale with the Cormack scale in the management of the airway of patients older than 18 years, undergoing general anesthesia operated at the Vicente Corral Moscoso Hospital, 2019. Methodology: cross-sectional analytical study developed in the "Hospital Vicente Corral Moscoso" with 160 patients who received general anesthesia and endotracheal intubation. The patients were ventilated with a face mask and evaluated with the Han Scale and during laryngoscopy with the Cormack Lehane Scale. The data were analyzed using descriptive and inferential statistics. Results: the mean age was 41.93 ± 17.12 years with a prevalence of 59.4% of the male sex. 12.5% of the patients presented obesity. 61.8% of the cases were ASA I. 66.2% of the patients were classified as Han grade I, 31.2% as grade II, and 2.5% as grade III. 66.8% of the patients presented Cormack I evaluation. Both scales found 2.5% Difficult Airway. When relating difficult ventilation with difficult laryngoscopy, a Fisher’s exact test was obtained with p = 0.097, Cohen’s kappa coefficient 0.231 (IC95% 0.385-0.075). Conclusions: it is not possible to demonstrate a relationship of the Han scale with the Cormack scale.
