Other studies show the complications which may occur in the tracheal wall due to the continuous use of the TETT, especially stenosis. Ĭurrent in vitro studies show that lower entrance of fluid secretions may occur, as shown in a study using dye (methylene blue) inserted in the oropharynx of animals (pigs) with TETT. Those same inflatable balloons can cause serious lesions in the contact area with the trachea, and maybe worsen a specific treatment (IMV). The balloons are also capable of preventing the entrance of solid residues and fluids, such as colonized secretions of the oropharynx and gastric content, which could lead to a series of complications such as respiratory infections and pneumonitis. The TETT holds terminal balloons (cuffs) which, when inflated, occlude the space between the tube and the tracheal wall, thus not allowing the air to scape. The traditional endotracheal tube (TETT) is largely employed in the medical area, particularly on patients who demand invasive mechanical ventilation (IMV). Mechanical assistance (invasive and non-invasive) to pulmonary ventilation is frequently necessary for the successful treatment of acute lung insufficiency and thus it is considered an important measure capable of saving the life of patients under critical conditions.
