Case report: occupational acute poisoning caused by the accidental release of lambda-cyhalothrin

Abstract

Lambda-cyhalothrin is a new-generation pyrethroid II insecticide that is neurotoxic. Most domestic and international reported cases are of oral poisoning, whereas few cases of inhalation and skin absorption poisoning have been reported. Here, we report the case of a 46-year-old man who was poisoned via dermal absorption and inhalation due to the rupture and leakage of the lambda-cyhalothrin pipeline. The patient developed a skin burning sensation, eyeball pain, and upper-limb tremor after exposure. After admission, the patient developed cough, sputum expectoration, chest tightness, and other symptoms. Lung computerized tomography indicated double pneumonia and the patient's electroencephalogram result was abnormal; the patient's condition improved after treatment.
