Abstract
Benzocaine-induced methemoglobinemia is a potentially life-threatening complication. We report two cases of methemoglobinemia due to topical benzocaine spray used as premedication for transesophageal echocardiography. A high index of suspicion is needed for this readily treatable condition.
摘要
苯佐卡因诱导的高铁血红蛋白血症是一种潜在的危及生命的并发症。我们报告了两例因在经食管超声心动图检查前使用苯佐卡因局部喷雾剂而导致高铁血红蛋白血症的病例。对于这种易于治疗的病症，需要高度怀疑。
