Endotracheal intubation is a procedure that consists in the placement of a tube into the trachea to establish and maintain an airway to provide adequate oxygenation, ventilate with positive pressure, or administer anesthetic gas in patients undergoing a surgical operation. It is an interface between the anesthesia machine and the patient. The aim of this study was to determine the insufflation pressure of the cuff in the endotracheal tube with the minimal leak technique. The results showed that, of a total of 339 subjects, 60 (17.7%) had pressures between 20 and 30 cm of H2O while 279 (82.3%) showed pressures of less than 20 or over 30 cm of H2O. We concluded that the minimal leak technique is a subjective one that has a high grade of inaccuracy, with a tendency to overinflate, which can lead to ischemia of the mucosa, with a consequential stenosis.
