Ultrasonography has become a useful tool for upper airway assesment. Its use has been directed to confirm proper endotracheal tube placement, but have not been described properly. This study was design in order to describe the prevalence of this ultrasonographic findings, and their differences between using a light stylet or a laryngoscope for this procedure. Methods. This cross sectional study enrolled 80 patients of the Fundacion Cardioinfantil Hospital without difficult airway predictors that required orotracheal intubation, 40 of them intubated by direct laryngoscopy, and the others using the light stylet. Ultrasonographic exploration of the airway was made, and intubation was followed with the ultrasound. The prevalence of this findings was stablished. Results An ultrasonographic description of the anatomic findings of the airway was done in all the patients. There was no difference between the 2 groups in stablishing a specific sign for identifying the intubation tool. The orotracheal tube was identyfied in 100% of the patients, and the prevalence for ultrasonographic signs for the confirmation of proper endotracheal tube placement was 87,1%, 86,3% and 48,8% for the double echogenic line, the bullet sign, and the snow-storm sign respectively. We found enough ultrasonographyc findings that may let us perform a successful ultrasound guided intubation in the light stylet group. Conclussion Ultrasonography is a useful tool for assessing the upper airway. There were no differences between the use of both intubation techniques related to idetification of an specific echocardiographic sign for each of the airway instruments. The orotracheal tube was identyfied in 100% of the patients. There are enough ultrasonographic findings in the stylet group for guiding succesful endotracheal tube placement.
