ภาวะพิษจากน้ำยาหล่อเย็น (เอทิลีนไกลคอล)

Key Facts

• Ethylene glycol (antifreeze) is extremely toxic; as little as 1 tablespoon can kill a cat
• Sweet taste makes it attractive to pets
• Three stages: neurological signs (30 min-12 hrs), apparent recovery (12-24 hrs), kidney failure (24-72 hrs)
• Early treatment is critical; antidote (fomepizole or ethanol) must be given within hours
• Calcium oxalate crystals in urine are characteristic finding
• Once kidney failure develops, prognosis is very poor
• Prevention: use propylene glycol-based antifreeze (safer); clean up all spills immediately
• Species: dogs and cats
