Abstract

Acquired methemoglobinemia is a medical emergency, and its prompt recognition and treatment can avoid catastrophic complications including death. However, in mild asymptomatic cases without any comorbid conditions, it would be reasonable to simply observe and treat symptomatically to avoid severe treatment-related complications, especially in patients with suspected glucose-6-phosphate dehydrogenase (G6PD) deficiency. We present a case of mild methemoglobinemia in occult G6PD deficiency in which the patient developed hemolysis after treatment with intravenous methylene blue, requiring transfusion.

摘要

获得性高铁血红蛋白血症是一种医疗急症,及时识别和治疗可避免包括死亡在内的灾难性并发症。然而,对于轻度无症状且无任何合并症的病例,单纯观察并对症治疗是合理的,以避免严重的治疗相关并发症,尤其是在疑似葡萄糖-6-磷酸脱氢酶(G6PD)缺乏的患者中。我们报告一例隐匿性G6PD缺乏导致的轻度高铁血红蛋白血症病例,该患者在接受静脉注射亚甲蓝治疗后发生溶血,需要输血。
