A 34-year-old woman presented with cyanosis and a methemoglobin level of 23.2% after perineal application of a topical anesthetic cream containing 20% benzocaine. Many commonly used products contain high levels of benzocaine, and their use can lead to life-threatening methemoglobin levels. This case reinforces the need for stricter guidelines for product use and warning labels to alert consumers to this potential side effect of topical benzocaine-containing products sold over the counter.
一名34岁女性在会阴部涂抹含20%苯佐卡因的外用麻醉乳膏后出现发绀，高铁血红蛋白水平达23.2%。许多常用产品含有高浓度苯佐卡因，使用这些产品可能导致危及生命的高铁血红蛋白水平。该病例强化了制定更严格产品使用指南和警示标签的必要性，以提醒消费者注意非处方销售的含苯佐卡因外用产品的这一潜在副作用。
