目的探讨三氯甲基碳酸酯吸人后的临床及肺部影像表现。方法回顾分析因三氯甲基碳酸酯泄漏吸人中毒17例患者的临床及肺部影像表现,并结合实验室检查指标,对三氯甲基碳酸酯损害肺部程度、进展及恢复情况进行探讨。结果 5例轻症患者,X 线与 CT 仅表现为两肺野散在少许斑片影;12例中、重症患者中3例以两肺多发小片状、结节影为主,病灶部分融合;9例累及全肺,表现为两肺广泛分布的大小不等的类圆形结节影及小灶不规则模糊增密影,部分融合,伴有小叶间隔及支气管壁增厚。影像与临床表现、实验室检查结果相符合。结论三氯甲基碳酸酯吸人后,肺部 X 线片与 CT 可观察肺部病变、肺水肿程度、进展及恢复情况,可协助临床早期治疗及评价疗效。
Objective To investigate the clinical and pulmonary manifestations of trichloromethyl carbonate after inhalation. Methods The clinical and pulmonary manifestations of 17 patients with inhalation of trichloromethyl carbonate leakage were retrospectively analyzed. The extent of lung damage, progression and recovery of trichloromethyl carbonate injury were discussed in combination with laboratory tests . Results In 5 cases of mild cases, X-ray and CT showed only a few patchy patches of lungs and lungs. In 12 cases, 3 cases of severe cases were complicated with small flaps and nodules in both lungs and partial fusion of lesions. Nine cases involving the whole lung, showing extensive distribution of the two lungs ranging in size between the round nodules and small lesions irregular fuzzy densification, partial fusion, with interlobular septa and bronchial wall thickening. Imaging and clinical manifestations, laboratory test results are consistent. Conclusion After inhalation of trichloromethyl carbonate, pulmonary X-ray films and CT can be observed pulmonary lesions, pulmonary edema, progression and recovery, can help early clinical treatment and evaluation of curative effect.
