Acute diarrhoeal illness remains a common medical problem in children with nearly 1.7 billion cases globally every year. We report five infants who, following severe diarrhoea, developed methaemoglobinemia. This is an altered state of haemoglobin presenting with cyanosis and can pose a diagnostic dilemma. It should be suspected in young infants without cyanotic heart disease presenting with severe diarrhoea, sepsis and cyanosis disproportionate to their clinical status. Its outcome depends on prompt treatment, the severity of underlying sepsis and co-morbidity.

与急性腹泻相关的婴儿期获得性高铁血红蛋白血症：病例系列。

急性腹泻疾病仍然是儿童的常见医疗问题，全球每年有近 17 亿病例。我们报告了五名婴儿在严重腹泻后出现高铁血红蛋白血症。这是血红蛋白状态的改变，表现为紫绀，可能会造成诊断困境。对于没有紫绀性心脏病且出现与其临床状况不相称的严重腹泻、败血症和发绀的小婴儿，应怀疑该病。其结果取决于及时治疗、潜在败血症的严重程度和合并症。
