胸片影像学改变在SARS患者诊断治疗及预后评估中的作用

Changes chest radiographic played a critical role in diagnosis, therapy and prognosis of SARS cases

目的!阐述胸片的动态变化对于SARS早期诊断、治疗的指导意义以及在预后评估中的作用。方法 回顾性分析25例确诊为SARS患者,根据预后分为3组,第1组为未进行无创正压通气(NPPV)而治愈出院组;第2组为使用NPPV治愈出院组;第3组为死亡及NPPV治疗尚未出院组;比较3组患者胸片的转归。结果 3组患者胸片开始及高峰时间均无显著性差异,但3组高峰持续时间逐渐延长,且第3组明显延长达(39.6±10.5)d;累及象限第3组为几乎双肺野全部受累;而第3组激素开始使用时间及激素高峰时间明显滞后,且持续使用时间最长;NPPV时间第3组明显延长。结论 胸片不仅能起到早期诊断SARS的作用,且密切关注胸片的变化对指导治疗、评估预后有重要的临床意义。@秦英智$目的!阐述胸片的动态变化对于SARS早期诊断、治疗的指导意义以及在预后评估中的作用。方法 回顾性分析25例确诊为SARS患者,根据预后分为3组,第1组为未进行无创正压通气(NPPV)而治愈出院组;第2组为使用NPPV治愈出院组;第3组为死亡及NPPV治疗尚未出院组;比较3组患者胸片的转归。结果 3组患者胸片开始及高峰时间均无显著性差异,但3组高峰持续时间逐渐延长,且第3组明显延长达(39.6±10.5)d;累及象限第3组为几乎双肺野全部受累;而第3组激素开始使用时间及激素高峰时间明显滞后,且持?

Objective To study the changes of chest radiographs and determine the critical role in the early diagnosis and therapy of severe acute respiratory syndrome(SARS), and to evaluate the imaging role in the prognosis. Methods 25 cases confirmed SARS were divided into three groups according to the final results of prognosis. Differences about radiographic progression and dynamic changes of corticosteroid among three groups were compared. Results The period of severe infiltration prolonged gradually among three groups and group 3 was the longest. Affected segments were predominant in one or two quadrants in group 1 and group 2, and the lesion almost involved the whole lungs and the initial management and the peak level dose was delayed obviously in group 3. Conclusion Chest radiographs could not only promote early recognition of SARS, but also play a key role in therapy and prognostic evaluation.
