Widely used for local anesthesia, especially prior to endoscopic procedures, benzocaine spray is one of the most common causes of iatrogenic methemoglobinemia. The authors report an atypical case of methemoglobinemia in a woman presenting with pale skin and severe hypoxemia, after a delayed repeat exposure to benzocaine spray. Early recognition and prompt management of methemoglobinemia is needed in order to lessen morbidity and mortality from this entity.
苯佐卡因喷雾剂广泛用于局部麻醉，尤其是在内镜检查之前，它是医源性高铁血红蛋白血症最常见的病因之一。作者报告了一例非典型高铁血红蛋白血症病例，该病例为一名女性，在延迟重复接触苯佐卡因喷雾剂后，出现皮肤苍白和严重低氧血症。为了降低该病症的发病率和死亡率，需要对高铁血红蛋白血症进行早期识别和及时处理。
