Anaesthetists are well trained to detect subtle skin signs of life-threatening situations such as cyanosis in hypoxia. However, cyanosis resulting from drug-induced, asymptomatic methaemoglobinaemia is rare and is likely to go undetected preoperatively. Patients presenting with asymptomatic methaemoglobinaemia may, therefore, offer a dramatic challenge to the unprepared anaesthetist. We report a case of methaemoglobinaemia secondary to dapsone ingestion that was diagnosed intraoperatively.
麻醉医生在检测危及生命情况的细微皮肤体征方面训练有素，比如缺氧时的发绀。然而，药物诱导的无症状高铁血红蛋白血症导致的发绀很罕见，术前很可能未被发现。因此，患有无症状高铁血红蛋白血症的患者可能会给毫无准备的麻醉医生带来巨大挑战。我们报告一例术中诊断出的因服用氨苯砜继发的高铁血红蛋白血症病例。
