Changes in mucociliary activity may be used to investigate the airway-irritating potency of volatile anaesthetics
We have examined the short-term effects of three volatile anaesthetics, halothane, isoflurane and desflurane, on mucociliary activity in the rabbit maxillary sinus in vivo. Mucociliary activity was recorded photoelectrically and the signal processed by fast Fourier transformation. Administration of 1.0 MAC of halothane, isoflurane or desflurane caused a temporary increase in mucociliary activity,
