title: Laryngeal mucociliary transport: normal values and under the influence of anesthetics. An experimental study in rabbits.
abstract: The larynx is the point of confluence of all tracheobronchial secretions and of the particles trapped within them. A study is made of laryngeal mucociliary transport using charcoal particles in 8 anesthetized rabbits and in 8 more during the immediate postmortem period. Most secretions were found to reach the posterior commissure, and were then swallowed. In the immediate postmortem rabbits, mucociliary transport velocity was 3.59 +/- 1.23 mm/min., with a transport time of 4.62 +/- 1.5 min. In the 8 rabbits anesthetized with droperidol, diazepam and thiobarbital, transport was found to be significantly slowed (p = 0.001).
