Man, 48, sees his urine turn FLUORESCENT after being poisoned with antifreeze

July 2, 2017  16:02

A man's urine turned fluorescent after being poisoned with antifreeze, a case report reveals.

The unnamed man, 48, believed to be from Texas, is thought to have accidentally ingested a coolant that caused his urine to glow blue-green.

After appearing at hospital vomiting and complaining of abdominal pain, tests revealed his blood pressure was dangerously low.

He was later diagnosed with poisoning via ethylene glycol - the active ingredient in active freeze that contains fluorescent compounds.

After spending four days in hospital, he has now fully recovered.  

Blue-green fluorescent urine  

The report authors wrote in BMJ Case Report: 'A man with diabetes mellitus and alcohol abuse presented to the emergency room with altered mental status, vomiting and abdominal pain. On examination, he was confused and uncooperative'. 

Test results revealed he had an abnormally low blood pressure and was breathing excessively fast.

Urine samples and mouth examinations confirmed he was suffering from ethylene glycol poisoning - a sign of antifreeze ingestion.

Ethylene glycol poisoning typically causes the body to produce excessive amounts of acid or slows the rate the kidneys remove acid.

Examining the man's urine sample under UV light revealed it was glowing blue-green fluorescent.

The authors wrote: 'Most antifreeze preparations have added fluorescein to help detect radiator leaks'. 

Yet, urine can appear fluorescent if somebody has eaten certain foods, ingested toxins or taken drugs. It also more commonly occurs in children.

The man was successfully treated via drugs, dietary supplements and dialysis.

He was discharged from hospital after four days. 

What is ethylene glycol poisoning?

Ethylene glycol is a colourless, odourless, sweet liquid, commonly found in antifreeze.

Early symptoms of poisoning include feelings of drunkenness, as well as vomiting and abdominal pain. Later signs are reduced consciousness, headaches and seizures.

It can also cause brain damage, kidney failure and death.

Treatment focuses on stabilising the patient and reversing the poisoning. Dialysis may be required if organ damage has occurred or if acid levels in the blood are excessively high.
