Abstract/OtherAbstract:
The ventilatory effects of 1 mg.kg-1 i.v. almitrine were studied in five dogs anaesthetized with halothane 2% under conditions of normoxia, hyperoxia and hypoxia. Ventilation (minute ventilation, respiratory frequency, tidal volume, duration of inspiration and expiration, ratio TI/Ttot and VT/TI), Pao2, Paco2, pHa, systemic arterial pressure and heart rate were measured in air before and following almitrine; in air, after inhalation of pure oxygen and after almitrine in hyperoxia; in air, during hypoxia with Fio2 progressively decreased from 0.21 to 0.12 and after almitrine in hypoxia (FIO2 = 0.12). Halothane decreased ventilatory response to hypoxia. Almitrine stimulated ventilation irrespective of the level of oxygenation and restored the ventilatory response to hypoxia. Hyperoxia did not suppress ventilatory action of almitrine whose action is probably partly central. Hypoxia and almitrine did not induce major systemic haemodynamic modification.
