Definition Ethylene glycol is a common ingredient in antifreeze and windshield de-icer. If eaten or swallowed, it is poisonous. It is not a common problem in Australia.
What is going on in the body? Ethylene glycol is very toxic. Every year, many people and animals are accidentally poisoned by ethylene glycol.
What are the signs and symptoms of the condition? The signs and symptoms of ethylene glycol poisoning are similar to alcohol intoxication. The first sign is slurred speech and a somewhat high feeling. Vomiting may occur. Later the central nervous system may become depressed, and coma can result. Congestive heart failure and fluids in and around the lungs may occur in later stages. The kidneys may stop working and death is possible.
What are the causes and risks of the condition? Eating or drinking ethylene glycol causes poisoning. Ethylene glycol is found in antifreeze and windshield de-icer and in other products. It tastes a very sweet and pets and children can ingest it by accident. Small amounts can be toxic.
What can be done to prevent the condition? Antifreeze and windshield de-icer should be kept out of the reach of children and pets. Ethylene glycol should not be spilled on the ground where it can be accidentally swallowed.
How is the condition diagnosed? Laboratory examinations done at the emergency room will test for too much acid in the blood. This condition is called metabolic acidosis. Certain crystals will also be found in the blood. Many anti-freezes have a dye added to them. A black lamp will show this dye in the urine. There is also a test for ethylene glycol.
What are the long-term effects of the condition? Long-term effects depend on the amount of ethylene glycol swallowed and how much time goes by before treatment is started. Kidney failure, congestive heart failure, heart damage and death can occur.
What are the risks to others? This is not a contagious disease.
What are the treatments for the condition? Upon arrival at the emergency room, sodium bicarbonate may be given to correct the acidosis of the blood. The stomach may be pumped and cleaned if no more than 30 minutes have passed since swallowing. The medication fomepizole (an antidote) may be given through an intravenous line into the arm. Some drugs can help change some of the toxic byproducts in the body. Dialysis may be done in cases of severe poisoning and if heart or kidney failure is likely.
What are the side effects of the treatments? The most common side effects associated with fomeprizole are dizziness, headache, and nausea. sodium bicarbonate can cause stomach cramps, bloating, and excessive thirst.
What happens after treatment for the condition? An individual can die from ethylene glycol poisoning. There can also be kidney failure and congestive heart failure that lingers after recovery.
How is the condition monitored? A physician or doctor can monitor ethylene glycol levels and kidney function in individuals who have been poisoned with ethylene glycol.
