目的通过分析青岛“11·22”特大事故发生后无偿献血情况,为重大突发事件中献血者组织动员及血液筛查应急检测工作提供参考。方法分别收集事故发生前后5天青岛市无偿献血人群资料进行分析比对,事故后血液筛查结果与前期数据进行比较。结果事故发生后5 d内本站共有3 650名献血者献血,无偿献血人次大幅度上升(406.0%),其中18~25岁人群所占比例最高(43.72%),初次献血者比例明显增加(65.51%),献血者身份以学生为绝对主力(31.48%)。3 650名献血者中,ALT不合格42例,HBsAg反应性13例,抗-HCV反应性9例,与前期比较不合格率均有所升高;梅毒螺旋体抗体反应性8例,HIVAg/Ab反应性1例,不合格率较前期比例降低。NAT反应性10例,其中固定献血者中NAT反应性比例最低(0.131%)。结论突发事件中献血者增加最多的为初次献血者,18~35岁人群成为献血主力军,学生和固定献血者群体病毒感染比例低,在危急情况下可以将其作为进行快速筛查的首选对象。
Objective To provide a reference for the mobilization of blood donors and the emergency screening of blood screening in major emergencies by analyzing the unpaid blood donation after the extraordinary accident of Qingdao “11 · 22”. Methods The data of unpaid blood donors in Qingdao City were collected and analyzed 5 days before and after the accident. The blood screening results after the accident were compared with the previous data. Results A total of 3 650 blood donors were donated within 5 days after the accident and the number of blood donation increased significantly (406.0%). Among them, the highest proportion of the population aged 18- 25 years (43.72%) was significantly higher than that of the first donors 65.51%). The blood donors’ identity was the absolute main force of students (31.48%). Of the 3 650 blood donors, 42 were not eligible for ALT, 13 were HBsAg-reactive, and 9 were anti-HCV reactive. Reactivity in 1 case, the failure rate lower than the previous ratio. There were 10 cases of NAT reactivity, among which the proportion of NAT reactivity in fixed blood donors was the lowest (0.131%). Conclusions The most frequent donors in emergencies are the first blood donors, and the population aged 18-35 is the main blood donor. The proportion of virus infection among students and fixed blood donors is low, and may be the first choice for rapid screening in critical situations Object
