Variables predictivas de diámetro y longitud de inserción de tubo endotraqueal en niños de 1 a 120 meses ingresados en el área de terapia intensiva del Hospital Vicente Corral Moscoso en el período mayo 2018- octubre 2019

Abstract

BACKGROUND: The main cause of morbidity and mortality in pediatrics includes the compromise of the airway and ventilation, proper intubation will save the patient's life, being therefore transcendent to consider age, height, weight and sex. OBJECTIVE: To determine the predictive variables of diameter and length of endotracheal tube insertion in children aged 1 to 120 months admitted to the Intensive Care area of Vicente Corral Moscoso Hospital. METHODS: Correlational study, with a sample of 102 intubated patients, determined the size of the tube used and the depth of insertion using x-rays; For qualitative variables descriptive statistics were used, for the quantitative Kolmogorov-Smirnov test, in the bivariate analysis the Mann Whitney U and Spearman correlation was used. Subsequently, the multivariate linear regression analysis was executed, the final equation was modeled and Pearson coefficients were obtained, finally ANOVA analysis was performed. RESULTS: The frequency of intubation was 30.6%, the most frequent reason was respiratory pathology. The diameter of the tube can be predicted individually using age, weight and height, and by combining age and weight the prediction increases to 64.9%. To estimate the depth of the tube, weight (63.4%), age and height are useful, and combining age and weight increases the accuracy to 65.2%. There is no correlation between diameter, insertion length and sex. CONCLUSIONS: The diameter and length of the endotracheal tube correlate with each patient's own variables such as age and weight.
