Decode the phenomenon of green bleeding

Canadian surgeons were extremely surprised to see that the patients they were operating were bleeding dark green leaves, exactly like a science fiction character.

According to doctors at St Paul Hospital, Vancouver, Canada, a few years ago received a patient who needed foot surgery. This 42-year-old man overslept in a sitting position, causing his legs to not circulate blood and risk being seriously affected.

At the beginning of the surgery, the bleeding of the patient is green. Doctors have discovered and discovered that he used drugs to treat migraine sumatriptan with large doses, 200mg a day.

The amount of medicine causes a rare and dangerous condition, named sulfhaemoglobinaemia . This means that the sulfur in the drug combines with the hemoglobin compound that transports oxygen in red blood cells, making the blood unable to bind to oxygen. Consequently, the blood changes color from magenta to green or dark blue.

The expert team performed foot surgery for the man and gradually reduced the dose of sumatriptan headache medicine. They said that if they did not fix it in time, it would damage internal tissues and damage the nervous system.

According to Dr. Alana Flexman working at St Paul Hospital, the patient recovered and stopped taking sumatriptan after discharge.5 weeks after the last migraine dose, the patient's blood returned to red. Fresh as usual.

According to scientists, the patient resembles the Spock character in the science fiction movie Star Trek. The character also has green blood and blood that contains copper compounds, not iron in the blood of ordinary people.
