The pulmonary CT manifestations of acute moderate or severe hydrogen sulphide poisoning fishermen

Abstract

To discuss the clinical manifestations and CT features of acute moderate or severe hydrogen sulphide poisoning fishermen. The clinic and CT datas of 8 acute moderate or severe hydrogen sulphide poisoning cases were retrospectively analysed. The lesions located at two pulmonary each leaf in 3 cases, located at both lower lungs in 3 cases and asymmetry leaves in 2 cases. Lesions form: little patchy shadow in 8 cases (8/8), fibrous band shadow in 4 cases (4/8), ground glass shadow in 3 cases (3/8), peripheral fuzzy interlobular nodule in 4 cases (4/8); 5 cases complicated with pleural effusion; After treatment 6 ∼ 10 days, the pulmonary shadows were absorbed obviously; Fibrous band shadow was residual in a case after a follow-up of 2 months. With definite history of hydrogen sulphide inhalation and the corresponding clinical manifestations, and if fishermen contacted for a long time, who would be made chemical pulmonary damage; Combined with the imaging manifestations, the diagnosis as well as the severity of pulmonary damage could be made.
