Abstract:
This paper reported a case of acute severe nitrite poisoning with massive pulmonary thromboembolism (PTE), discussed the pathogenesis and summarized the treatment experience. Common symptoms of nitrite poisoning include headache, abdominal pain, shortness of breath, cyanosis, etc., which can be followed by encephalopathy, neurological dysfunction, hemolysis, etc. However, the cases of PTE are rare in clinical practice and are prone to missed diagnosis. Nitrite and methemoglobin may lead to vascular endothelial damage and promote thrombosis. In the diagnosis and treatment of acute severe nitrite poisoning patients, the targeted preventive measures should be taken.
