- Description
- The steroid induction agent, Althesin, infused intravenously in light anesthetic doses in otherwise unsedated man (84 μg kg⁻¹ min⁻¹) and rabbit (140 μg kg⁻¹ min⁻¹) causes similar autonomic and somatic effects. In the rabbit, the rise in heart rate (mainly due to central vagal blockade) and the selective depressant effects on respiratory rate are independent of CNS 5-hydroxytryptamine and noradrenaline. The rise in arterial pressure and the fall in hindlimb conductance is dependent on CNS 5-hydroxytryptamine and noradrenaline synthesizing neurons, which are probably arranged in series. These findings provide a working hypothesis for the mechanisms of action of Althesin on central cardiopulmonary controls in man.
