[Study on clearance of chlorfenapyr via blood purification (a case analysis)]

This paper analyzed the clinical data of a patient with acute oral emamectin·chlorfenapyr poisoning, and discussed the effect of blood purification therapy on chlorfenapyr poisoning. Chlorfenapyr was detected in the blood, urine, ultrafiltrate and plasma exchange fluid of the patient, and the concentrations of chlorfenapyr poison gradually decreased with time. Blood purification has a certain effect on chlorfenapyr, and early blood purification may be an effective measure to treat chlorfenapyr poisoning.

[A case report of death from toxic encephalopathy caused by emamectin·chlorfenapyr]

Emamectin·chlorfenapyr is insecticide compounded by emamectin benzoate and chlorfenapyr. There is no special antidote after poisoning, and the mortality rate of patients is very high. We admitted a case of toxic encephalopathy caused by oral administration of emamectin·chlorfenapyr. The clinical manifestations of patient were gastrointestinal symptoms, profuse sweating, high fever, changes in consciousness. After admitted to the hospital, despite active comprehensive treatment, the patient died of ineffective rescue eventually.

[Two case report of death from acute compound chlorfenapyr poisoning]

Chlorfenapyr is a moderately dangerous insecticide widely used in agriculture. The mortality of acute poisoning patients is high, and there is no effective treatment. This paper retrospectively analyzes the clinical data of two cases of compound chlorfenapyr poisoning. The main symptoms of the patients were high fever, sweating, gradual coma, increased creatine kinase and myoglobin, with delayed poisoning symptoms. Despite comprehensive treatment, both patients died eventually. It indicated that chlorfenapyr was highly toxic and had a high mortality. In addition to routine symptomatic treatment for patients with acute poisoning, blood purification treatment should be actively carried out in the early stage.

[A case report of death from acute emamectin·chlorfenapyr poisoning]
