Cyanosis is a clinical sign indicates lack of tissue oxygenation due to various causes. Methemoglobinemia is one of those causes due to oxidation of iron moiety of haem in haemoglobin, making it a lesser oxygen carrier to tissue. Various drugs, gases and substances can produce oxidative stress upon a genetically predisposed or a normal individual, converting haemoglobin to methaemoglobin and cause varying degree of cyanosis. Prompt identification and proper antidote can save patient’s life and decreases need for unnecessary invasive ventilatory support and complications.
