Abstract
Iodocaine administered as a bolus intra-arterially immediately prior to contrast media injections significantly decreased the pain experienced from aortofemoral arteriography. Some researchers advocated mixing 2 mg of lidocaine with each ml of contrast agent rather than giving it as a bolus prior to the contrast agent. In a randomized study of 30 patients, both methods were equally effective in decreasing the pain from aortofemoral arteriography mixing the lidocaine with the contrast agent was the easier method.
