Relación entre la ubicación del tubo endotraqueal y distancia de la protuberancia mentoniana al ángulo de Louis, Hospital Vicente Corral Moscoso, Hospital José Carrasco Arteaga. Cuenca. 2019-2020

Abstract

Introduction: The management of the airway is important for all physicians, a fundamental part is to know the depth of the endotracheal tube, therefore, methods must be developed to avoid causing damage by selective intubation or extubation. Objective: To determine if there is a relationship between the location of the endotracheal tube and the distance from the chin protrusion to the Louis angle with the head in a neutral position in adults. Methodology: Observational, descriptive, cross-sectional and correlational study of 151 patients at the Vicente Corral Moscoso and José Carrasco Arteaga Hospitals in Cuenca Ecuador. The data was collected using a form from March 2019 to March 2020. The tabulation and analysis was done in the IBM-SPSS 20 software with descriptive measures, correlations and linear regression. Results: The most important measurements of the airway of the 151 patients from the dental arch are: to the vocal cords 13.0742 ± (1.36262) cm, to the carina with the head in neutral position 23.3159 ± (1,97859) cm; from the chin protrusion to the angle of Louis with the head in a neutral position 12.9921 ± (1.67954) cm. A Pearson R of 0.509 (p <0.05) was obtained, the following formula was developed: Endotracheal tube depth = (15.531 + (0.599 x protuberance at Louis angle) - 3) Conclusions: In the studied population there was a moderate correlation between the studied measures, a statistically significant formula and recommendations for the depth of the endotracheal tube were developed.
