摘要

苯佐卡因喷雾广泛用于局部麻醉，特别是内镜手术前，是医源性高铁血红蛋白血症的最常见原因之一。作者报告了一个非典型的高铁血红蛋白血症的情况下，一名妇女呈现苍白的皮肤和严重的低氧血症，延迟重复暴露于苯佐卡因喷雾。为了减少高铁血红蛋白血症的发病率和死亡率，需要对其进行早期识别和及时治疗。

Atypical presentations of methemoglobinemia from benzocaine spray.

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.
