Feeling blue: US woman treated by doctors after blood turned navy
Feeling blue: US woman treated by doctors after blood turned navy
It turns out that "feeling blue" is not a figure of speech after all.
A 25-year-old woman has given new meaning to the expression after she turned up at a Rhode Island hospital with blood that had turned navy blue.
According to a paper in the New England Journal of Medicine, the woman told doctors that she had used a topical pain reliever for a toothache. She woke the next morning and took herself to hospital, telling doctors: "I'm weak and I'm blue."
The woman was what doctors call cyanotic – the medical term for seeming to have blueish skin or nails.
Dr Otis Warren, the emergency room doctor on duty at Miriam hospital in Providence, the state capital, diagnosed the problem as "acquired methemoglobinemia" – a rare blood disorder that causes people to produce an unusual amount of methemoglobin (a type of hemoglobin). With methemoglobinemia, the hemoglobin can carry oxygen, but cannot release it effectively to tissues, according to the National Library of Medicine.
