目的通过分析汶川、芦山地震前后无偿献血人群的结构状况,可为类似突发事件发生后无偿献血者的招募及开发血源潜力提供依据。方法收集汶川地震前2008年4月1~30日、汶川地震后2008年5月12日~6月1日,芦山地震前2013年3月1~31日、芦山地震后2013年4月20日~5月9日,成都市血液中心所有献血者的献血记录,分别对2次地震前后不同血型、民族、性别、年龄段、职业和教育程度的献血者变化进行比较分析。结果地震发生后献血人数较震前明显增加。汶川震后男性献血者5 319名(58.7%),女性3 745名(41.3%);芦山献血者男性4 807名(47.5%),女性5名(52.5%)。汶川地震后>30岁献血人数有所增加。芦山地震后>30岁献血人数有所减少。学生、职员献血占比例较高。结论地震发生后群众参与献血的热情会增加,要制定合理的采血策略,避免血液浪费。
Objective To analyze the structural status of unpaid blood donors before and after the Wenchuan and Lushan earthquakes and to provide basis for recruiting and developing the blood potential of unpaid blood donors after similar emergencies. Methods Pre-Wenchuan earthquake was collected from April 1 to April 30, 2008 after the Wenchuan earthquake from May 12 to June 1, 2008, before Lushan earthquake on March 1 to March 31, and after Lushan earthquake on April 20, 2013 ~ May 9, blood donation records of all blood donors in Chengdu Blood Center were used to compare and analyze the changes of blood donors before and after the two earthquakes in different blood groups, ethnic groups, sexes, ages, occupations and educational levels. Results The number of blood donations after the earthquake increased significantly compared with that before the earthquake. There were 5 319 (58.7%) male blood donors and 3 745 (41.3%) male donors after the Wenchuan earthquake. There were 4 807 male (47.5%) male and 5 female (52.5%) female donors in Lushan. After the Wenchuan earthquake> 30-year-old blood donation increased. Lushan earthquake> 30-year-old blood donation has been reduced. Students, staff blood donation accounted for a higher proportion. Conclusion After the earthquake, the enthusiasm of the public to participate in blood donation will increase. To develop a reasonable blood sampling strategy to avoid blood waste.
