title: [Hemodynamic effects of dopamine, dobutamine and isoproterenol in chronic respiratory insufficiency].
abstract: A study of the effects of dopamine, dobutamine and of isoprenaline was carried out in 20 patients with chronic respiratory insufficiency, 16 of whom had pulmonary arterial hypertension (PAP: 22 mmHg). The following findings emerged: --absence of any significant effect of dobutamine on heart rate,--increase in systolic and mean PAP, after infusion of dobutamine,--increase in systolic and mean PAP, after infusion of dopamine,--decrease in BP after administration of infusion of dobutamine,--decrease in pulmonary arterial resistances under the influence of isoprenaline,--decrease in total systemic resistances after the administration of dobutamine,--increase in ventricular, systolic work after the infusion of dopamine.
