title: Severe adverse reactions to contrast media: a simplified means of recognition and treatment.
abstract: Severe adverse reactions to contrast media appear to fail into two major categories: (1) histamine response and (2) vagus response. Treatment of these major reacions is simiplied once the cause is recognized. Pulse rate is a simple means of determining which effect is being observed, and appropriate treatment can be instituted without undue delay.
