Trichloroethylene poisoning is a disease caused by exposure to excessive amounts of trichloroethylene. Trichloroethylene is a cumulative agent for the central nervous system, and it causes damage to the liver, kidneys, and heart. Acute poisoning presents with symptoms similar to drunkenness, headache, dizziness, irritability, and hysterical manifestations. Severe cases present with toxic encephalopathy as well as damage to the liver, kidneys, and heart; during the recovery phase, neurodepression and paranoiac psychosis may occur. Acute trichloroethylene poisoning is primarily characterized by depression of the central nervous system. Craniial nerve damage and significant heart, liver, or kidney impairment do occur, but they are relatively rare. A diagnosis can be made based on a comprehensive analysis of the contact history and examination results. However, it should be differentiated from disorders of consciousness caused by other reasons, as well as cranial nerve diseases and heart, liver, and kidney diseases. Trichloroacetic acid and trichloroethanol can be detected in urine and blood. Chronic poisoning is characterized by toxic neurosis, toxic myocarditis, liver damage, and peripheral neuropathy; it often affects the sensory branches of the trigeminal nerve, leading to disorders of taste and smell as well as sensory disturbances in the face and the front part of the tongue. Trichloroacetic acid can cause contact dermatitis. Apart from disengagement, treatment is mainly symptomatic.
