摘要
目的：初步探讨六氯乙烷吸入性肺损伤HRCT（high-resolution）首次检查的恰当时间.方法：对8例六氯乙烷急性肺损伤患者采用64层螺旋CT在肺损伤后（首次9.50～10.00 h,第2次27.25～30.50 h,第3次51.20～56.00 h）行胸部扫描,并分析其CT表现.结果：首次CT检查,7例（87.5％）图像未显示异常,1例（12.5％）图像显示右肺下叶内基底段“毛玻璃样”改变;第2次CT检查,7例（87.5％）图像显示肺呈“毛玻璃样”改变,部分伴实变影,1例（12.5％）并发纵隔气肿,其中6例（75.0％）CT检查首次显示异常,1例（12.5％）正常;第3次CT检查,图像均显示肺呈“毛玻璃样”改变,部分伴实变影,其中1例（12.5％）CT检查首次显示异常.第2次CT首次显示异常率（75.0％）明显高于首次CT检查（12.5％）及第3次CT检查（12.5％）（x2=15.54,P＜0.05x2=13.98,P＜0.05）.结论：建议六氯乙烷急性肺损伤CT首次检查在27.00～30.00 h内进行.
Objective To determine an optimal interval between hexachloroethane smoke inhalation lung injury and initial high-resolution CT（HRCT） scans. Methods Totally 8 patients with hexachloroethane smoke inhalation lung injury underwent HRCT of the chest in a single-breath-hold technique. Three scans were performed after inhalation lung injury. The time between exposure to hexachloroethane smoke and the initial CT scans ranged from 9.50 to 10.00 hours, the second CT scans from 27.25 to 30.50 hours and the third CT scans from 51.20 to 56.00 hours. The HRCT scans were retrospectively reviewed.Results The initial CT scans showed normal in 7 patients（87.5%） and patchy areas of ground-glass opacity （GGO） in the right medial basal segment in 1 patient. The second CT scans revealed GGO and consolidation in 7 patients （87.5%）, and normal in 1 patient（12.5%）. Among the 7 patients, initial abnormalities were observed in 6 patients（75.0%）, and pneumomediastinum was found on CT scans in 1 patient（12.5%）. The third CT scans showed GGO and consolidation in all patients, and initial abnormalities were observed in 1 patient（12.5%）. The initial abnormalities rate found on the second CT scans（75.0%） was significantly higher than that on the initial CT scans（12.5%） and off the third CT scans（12.5%）ff2=15.54, P〈0.05;）（2=13.98, P〈0.05）. Conolusion It is suggested that interval between hexachloroethane smoke inhalation lung injury and initial high-resolution CT（HRCT） scans range from 27.00 to 30.00 hours.
