Mr Spock's green blood is down to copper

 

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 42-year-old man emulated Star Trek's Mr Spock - a Vulcan who had green blood.

 

Instead, the unusual colour of his blood was down to the migraine medication he was taking.

 

The man's leg surgery went ahead successfully and his blood returned to normal once he eased off the drug.

The patient had been taking large doses of sumatriptan - 200 milligrams a day.

 

This had caused a rare condition called sulfhaemoglobinaemia, where sulphur is incorporated into the oxygen-carrying compound haemoglobin in red blood cells.

 

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.

 

"When seen five weeks after his last dose, he was found to have no sulfhaemoglobin in his blood."

 

The man had needed urgent 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 blood flow and causes localised tissue and nerve damage.

 

It is commonly caused by trauma, internal bleeding or a wound dressings or cast being too tight.

 

According to the fictional TV series Star Trek, Mr Spock of the starship Enterprise had green blood because the oxidizing agent in Vulcan blood is copper, not iron, as it is in humans.
