article imagePatient bleeds dark green blood

A man bleeds dark green blood after being operated. He had this green blood because of overdosing on medication which created a rare condition sufhaemoglinaemia, which produces green blood.
A team of Canadian surgeons got a shock when the patient they were operating on began shedding dark greenish-black blood, the Lancet reports.
The man emulated Star Trek's Mr. Spock - the Enterprise's science officer who supposedly had green Vulcan blood.
The 42 year old patient had been taking large doses of sumatriptan (for migraine medication) about 200 milligrams a day. As a result of this medication, it caused in his body a rare condition called sulfhaemoglinaemia, where sulfur gets incorporated into the oxygen carrying compound hemoglobin in red blood cells. Because of this condition, when the doctor operated on him, it gave dark green blood instead.
Describing the case in The Lancet, the doctors led by Dr Alana Flexman from St Paul's Hospital in Vancouver wrote: "The patient recovered uneventfully, and stopped taking sumatriptan after discharge.
Dr. Alana Flexman saw this patient again after five weeks and found he had no sulfhaemoglobin in his blood stream.
The man was admitted after he had required an emergency surgery because he had developed a dangerous condition in his legs after falling asleep in a sitting position.
The surgeons performed urgent fasciotomies, limb-saving procedures which involve making surgical incisions to relieve pressure and swelling caused by the man's condition - compartment syndrome.
In compartment syndrome, the swelling and pressure in a restricted space, limits the amount of blood flow and causes localized nerve and tissue damages.
It is commonly caused by trauma, internal bleeding or a wound dressings or cast being too tight.
He is healthy now must have been a big shock for everyone. Hope they put a warning on this medication, so others don’t exhibit the same condition.
