Comparison of pain and heat sensation of contrast media in aortofemoral angiography: meglumine-amidotrizoate (Angiografin) mixed with lidocaine versus sodium-meglumine-ioxaglate (Hexabrix).

A total of 116 translumbar aortofemoral angiograms were performed in 92 patients. At random, 58 contrast injections were done with Hexabrix and 58 with Angiografin mixed with lidocaine. Pain and heat sensation was evaluated by a verbal rating system. Most patients in both groups had no or mild pain sensation. There was, however, a slight but statistically significant difference (p less than 0.05) in favor of Hexabrix. No difference was found in heat sensation in either of the groups.
