Benzene poisoning:
Poisoning caused by inhalation of benzene vapor through respiratory tract or skin contact with benzene. There are acute and chronic. Acute benzene poisoning mainly produces anesthetic effect on the central nervous system, leading to coma and muscle twitching; High concentrations of benzene are irritating to the skin. Long-term exposure to low-concentration benzene can cause chronic benzene poisoning, hematopoietic dysfunction, early leukopenia, and then thrombocytopenia and anemia. Patients may have nosebleeds, gingival bleeding, subcutaneous bleeding, menorrhagia and other clinical manifestations. Acute cases mainly take first aid and symptomatic treatment. In chronic benzene, various drugs can be used to stimulate bone marrow cells to make blood, and blood transfusion can be used if necessary; Once the patients with chronic benzene poisoning are diagnosed, they should leave benzene operation as soon as possible, so that they should not be exposed to benzene and related compounds for a short time after treatment and rehabilitation.
