The effects of intravenous clonidine on ventilation.
The effects of clonidine, an alpha 2 adrenergic agonist, on ventilation were studied in a group of adult volunteers. The ventilatory variables measured were minute ventilation, respiratory rate, end-tidal carbon dioxide tension and the response to carbon dioxide challenge. We found no differences in minute ventilation, respiratory rate and end-tidal carbon dioxide tension, before and after clonidine administration. However, the ventilatory response to carbon dioxide was significantly attenuated following clonidine, suggesting that clonidine has respiratory depressant effects.

The cuffed pharyngeal airway.
A new self-retaining nasopharyngeal airway is described. The clinical performance of this airway was assessed in 100 patients during anaesthesia with spontaneous respiration. The physical behaviour of the airway was investigated in four patients. In an additional 25 patients the tube was used via the oral route. Although designed for use by the nasal route, the airway can be used as a self-retaining oropharyngeal airway.
