Abstract：
Cyanosis is typically a sign of a potentially life-threatening condition in the emergency department and requires immediate workup and treatment. This case report highlights the diagnostic reasoning and clinical approach to cocaine- and volatile nitrite-induced methemoglobinemia (MHG). MHG is a rare, life-threatening cause of cyanosis. The diagnosis must be suspected in the emergency department in the presence of hypoxia and cyanosis disproportionate to cardiopulmonary repercussions and refractory to oxygen supplementation. Acquired causes are more prevalent than genetics, and recreational drugs should be highly suspected. Despite the rarity of this situation, cyanosis precipitants and the specificities of each hemoglobinopathy are reviewed in this article.
摘要：
发癣通常是急诊科可能危及生命的迹象，需要立即进行检查和治疗。此病例报告重点介绍了可卡因和挥发性亚硝酸盐引起的高铁血红蛋白血症（MHG）的诊断推理和临床方法。MHG是一种罕见的，会危及生命的紫癜.在存在缺氧和紫癜的情况下，必须怀疑急诊科的诊断与心肺反应不成比例，并且难以补充氧气。获得性原因比遗传更普遍，和娱乐性毒品应该被高度怀疑。尽管这种情况很少见，本文对紫癜的沉淀和每种血红蛋白病的特异性进行了综述。
