title: [Mucociliary clearance function and medicamentous modification].
abstract: Mucociliary clearance represents a complex self-cleaning mechanism of the lung and is based on the functional unity of ciliated columnar cells and the special viscoelastic properties of the secretion produced in the tracheobronchial system. It has been known for a long time that intubation and mechanical ventilation can impair mucous transport and lead to morphological damage to the tracheobronchial mucosa. Recent studies made it clear, however, that mechanical ventilation during anaesthesia using an appropriate anaesthesiological technique has no deleterious effect on mucus transport in patients with healthy lungs. Ventilated patients in the intensive-care unit frequently have impaired mucus transport, which is associated with the development of retention of secretion and nosocomial pneumonia. In these patients a number of factors combine to form a formidable potential insult to the mucociliary transport mechanism. Numerous drugs can affect mucociliary transport. Beta-mimetics and theophylline, in particular, have a favourable effect on mucociliary transport, whereas the effect of mucolytic agents is controversial.
