Radiographic contrast agents in angiocardiography.

Contrast agents in angiocardiography.

Hexabrix--a new contrast medium in angiocardiography.

The hyperosmolality of current ionic angiographic media gives rise to several adverse effects. Use of the first low-osmolality medium, metrizamide (Amipaque), has been inhibited by expense and by the necessity for prior mixing into solution. Hexabrix is the first of such media to be available in stable solution, and its use in angiocardiography is reported, in direct comparison with Urografin, ...

Epileptogenic effects of radiographic contrast agents: experimental study.

Electrical activity in cells directly exposed to water-soluble radiographic contrast agents was investigated by intracellular recordings from neurons of the abdominal ganglia of Aplysia. Measurements of membrane resting potential, membrane conductance, synaptic and action potential configuration, and spontaneous electrical activity were performed. Test solutions included sodium diatrizoate, meg...

The physiologic effect of contrast media used for angiocardiography.

The deaths from angiocardiography at Wisconsin General Hospital were reviewed and found to be two per cent of 249 patients. These 5 deaths are reported briefly. Investigation was carried out to determine the hemodynamic effects of contrast substances on 12 dogs. In general, there was a temporary increase in right atrial and pulmonary arterial pressure followed by a rather marked decrease in sys...
