Abstract：
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.
摘要：
急性腹泻病仍然是儿童的常见医疗问题，全球每年有近17亿病例。我们报告了五个婴儿，严重腹泻后，出现了高铁血红蛋白血症.这是血红蛋白的改变状态，表现为紫癜，并可能造成诊断困境。在没有紫癜性心脏病并出现严重腹泻的婴儿中，应怀疑这种情况，败血症和紫癜与他们的临床状况不成比例。其结果取决于及时治疗，潜在脓毒症的严重程度和合并症。
