Urticaria within one hour of lidocaine injection is a sign of type I (immediate) hypersensitivity to lidocaine, yet most patients suspected of having a lidocaine allergy do not exhibit urticaria. Aside from being a sign of a rare lidocaine allergy, urticaria can also be a symptom of COVID-19. COVID-19 patients who experience urticaria after receiving lidocaine require careful evaluation to determine the cause. Here, we present a case of a patient exhibiting urticaria one hour after a lidocaine injection for the Pecto-intercostal nerve block to treat COVID-19-induced costochondritis.
利多卡因注射后一小时内出现荨麻疹是对利多卡因I型（速发型）超敏反应的迹象，但大多数疑似利多卡因过敏的患者并未出现荨麻疹。除了是罕见的利多卡因过敏迹象外，荨麻疹也可能是新冠病毒病（COVID-19）的症状。接受利多卡因后出现荨麻疹的COVID-19患者需要仔细评估以确定病因。在此，我们报告一例患者，其在接受利多卡因注射用于胸肋神经阻滞以治疗COVID-19引起的肋软骨炎后一小时出现荨麻疹。
