Fiberoptic bronchoscopy can be performed at the patient's bedside. This technique allows direct visualization of the upper and lower airways up to the segmental and subsegmental bronchi. Its most frequent indications are airway examination ot evaluate damage produced by toxins or the endotracheal tube, patency of the endotracheal tube and extubation failure. It is also used to obtain microbiological samples, facilitate intubation when difficult, aspirate airway sections or mucus plugs, perform bronchoalveolar lavage and administer drugs. With prior preparation, adequate monitoring and sedation, material according to the size of the patient and correct techniques, there are few complications. However, the procedure can produce trauma and obstruction of the airway, bronchial hemorrhage, barotrauma, loss of alveolar recruitment, bronchospasm, hypoxemia, bradycardia, and bronchopulmonary infection.
