Intra-arterial lidocaine was found to be an effective and safe method for reducing pain associated with peripheral angiography. A convenient method for delivery is to directly mix 2% lidocaine and contrast material in a ratio of 1:10 by volume. In a comparative evaluation, 25 of 29 patients experienced significantly less discomfort when the lidocaine-contrast mixture was used as compared to contrast material alone. There were no apparent complications from the use of intra-arterial lidocaine.
动脉内注射利多卡因被发现是一种减轻外周血管造影相关疼痛的有效且安全的方法。一种便捷的给药方法是将2%利多卡因与造影剂按体积比1:10直接混合。在一项对比评估中，与单独使用造影剂相比，29例患者中有25例在使用利多卡因-造影剂混合物时不适明显减轻。使用动脉内注射利多卡因未出现明显并发症。
