[Correct placement of the endotracheal tube]. / Colocación correcta del tubo endotraqueal.

The authors present their experience with correct placement of an endotracheal tube. Thirty children were intubated for different indications following the same method. The correct position of the tube was confirmed by chest films. The method included: 1. Tracheal tube introduction by direct laryngoscopy. 2. Deliberate tube displacement to the main right bronchus. 3. Auscultatory carina detection while giving positive pressure ventilation with ambu, when the respiratory murmur appears in the left hemithorax. 4. Tube withdrawal a distance equal to the patient's little finger length, leaving off the tracheal tube tip at an appropriate distance from the carina. The placement was found correct in 29 cases.
