Methaemoglobinaemia is a rare condition characterised by increased quantities of haemoglobin in which the iron of haem is oxidised to the ferric (Fe3+) form. Clinically the condition presents with cyanosis and low oxygen saturations on pulse oximetry but normal oxygen saturation on arterial blood gas analysis. Most cases are acquired and are frequently drug related. We present a case of methaemoglobinaemia which presented to our hospital.
高铁血红蛋白血症是一种罕见病症，其特征是血红蛋白数量增加，其中血红素的铁被氧化为三价铁（Fe3+）形式。临床上，该病症表现为发绀，脉搏血氧饱和度测定显示氧饱和度低，但动脉血气分析显示氧饱和度正常。大多数病例是后天获得的，且常常与药物有关。我们报告了一例在我院就诊的高铁血红蛋白血症病例。
