目的：通过比较分析4·20芦山地震重灾区与轻灾区伤员的伤情特点，为优化震后医疗资源调配提供依据。方法收集震后1周内、就诊于四川大学华西医院急诊科的地震伤员病历资料，回顾性分析重灾区与轻灾区伤员的伤情严重程度、受伤部位、受伤类型。结果重灾区与轻灾区伤员伤情严重程度及受伤部位无统计学差异。重灾区伤员中，骨折伤员比例少于轻灾区（50%和69%，P=0.020），软组织伤比例大于轻灾区（22%和10%，P=0.005）。结论在震后灾区医疗资源配置上，绝大部分医疗资源的需求比例在重灾区与轻灾区无差异，仅需在有关骨折伤与软组织伤的个别医疗资源调配比例方面稍作调整，但仍以骨科医疗资源为主。“,”Objective To explore the differences on the injuries’charactors between the patients from different disaster area. Methods A retrospective analysis of the one-week casualty was conducted on Lushan earthquake, including severity, portion of casualties and injured types from different districts. Results There was no statistical difference in severity and injured portion between different districts. The proportion of fractures for the heavily damaged area was smaller than that of the other area (50%VS 69%, P=0.020), but its proportion of soft tissue injuries was larger (22% VS 10%, P=0.005). Conclusion In Lushan earthquake, no statistical difference was found in injured portion and severity between the two districts. Fractures more frequently occurred in the less damaged area, while the proportion of soft tissue injuries was larger in heavily damaged area. Bearing that in mind, only the portion of the medical demands related to fracture and soft tissue injury has to be taken into account.
