[One case of methemoglobinemia and hemolytic anemia caused by acute nitrogen trifluoride poisoning].

This paper analyzes the pathogenesis, clinical characteristics, treatment measures and prognosis of a case of methemoglobin and hemolytic anemia caused by acute nitrogen trifluoride poisoning. The patient with occupational exposure to nitrogen trifluoride was treated immediately after the onset of illness, methemoglobin was monitored and a comprehensive examination was conducted. After comprehensive analysis, it was considered that acute nitrogen trifluoride poisoning could cause methemoglobinemia, hemolytic anemia and liver injury. The patient was disengaged and given symptomatic treatment such as oxygen therapy, methylene blue, low-dose methylpredrone, vitamin C and reduced glutathione. The prognosis of the patient is good, which provides a reference for the clinical treatment and occupational health examination of nitrogen trifluoride poisoning.
