Physicians may administer intravenous dyes to patients, most commonly to delineate vascular or urinary anatomy, without an appreciation of the potential hazards associated with these compounds. We report two cases in which skin eruptions followed the intravenous administration of the dyes fluorescein and methylene blue; these eruptions were the same colors as the dyes. In our first patient, urticaria, which was yellowish in color and fluorescent under a Wood's lamp, occurred after the administration of fluorescein. In the second patient, painful blue macules appeared randomly on the forearm within 15 seconds after methylene blue was injected into a free-flowing intravenous cannula on the dorsal aspect of the hand.
医生可能会给患者静脉注射染料，最常见的是用于描绘血管或泌尿系统的解剖结构，而未意识到这些化合物存在的潜在危害。我们报告两例病例，在静脉注射荧光素和亚甲蓝染料后出现了皮肤疹；这些皮疹的颜色与染料相同。在我们的首例患者中，注射荧光素后出现了荨麻疹，其颜色呈淡黄色，在伍德灯下有荧光。在第二例患者中，将亚甲蓝注入手背背侧自由流动的静脉套管后15秒内，前臂上随机出现了疼痛的蓝色斑疹。
