Abstract/OtherAbstract:
1. The effects of dopamine and dobutamine on the pulmonary haemodynamic response to hypoxia were studied in nine anaesthetized dogs under hypoxaemia induced by ventilation with hypoxic gas mixture. 2. From the present study, only dopamine infusion reduced arterial oxygenation during hypoxic hypoxaemia, whereas catecholamine maintained it at the same level during normoxaemia. 3. A redistribution of perfusion to the pulmonary vasculature may be related to a reduction of arterial oxygenation with dopamine infusion during hypoxic hypoxaemia. 4. It is presumed that an increase in pulmonary blood flow would emphasize an inhibition of hypoxic pressor response in the pulmonary vasculature, which may not be a direct effect of dopamine.
