目的探讨拉萨市长期出现B型、O型血源紧张的原因,确定应对措施,以指导血液中心采供血工作及保障临床用血。方法对拉萨市2010年1月-2015年5月所有无偿献血者人口学特征及血型进行统计分析。结果西藏拉萨市2010年1月-2015年5月期间共有23 811人次无偿献血者,其中藏族5 080人次、汉族18 710人次,其他民族21人次;血型以O型血为主,有8 564人次,占35.97%,其次是B型血,有7 655人次,占32.15%;拉萨市藏汉2族献血者中,A型、B型、O型、AB型血型构成比差异具有统计学意义(χ~2=152.01,P<0.01);拉萨市区医院2010年1月-2015年5月临床用血量以B型及O型血为主,分别占33.40%、36.77%。结论拉萨市2010年1月-2015年5月期间无偿献血者ABO血型中,B型及O型血所占比例都低于各自临床用血量所占比例,是血供应紧张的主要原因;提高藏族人群无偿献血比例,建立采供血安全机制是解决拉萨市B型及O型血液长期紧张的可行措施。
Objective To explore the causes of long-term occurrence of type B and type O blood tension in Lhasa and to determine the countermeasures to instruct the blood center to collect and supply blood and to protect clinical blood. Methods The demographic characteristics and blood type of all unpaid blood donors in Lhasa from January 2010 to May 2015 were statistically analyzed. Results There were 23 811 unpaid blood donors in Lhasa, Tibet from January 2010 to May 2015. Among them, 5 080 were from Tibetans, 18 710 were from Han nationality and 21 were from other ethnic groups. Blood type was mainly O blood type with 8 564 person-times , Accounting for 35.97%, followed by type B blood, with 7 655 person-times, accounting for 32.15%. Among the blood donors from Tibetan and Han ethnic groups in Lhasa, the constituent ratios of type A, type B, type O and type AB were statistically significant χ ~ 2 = 152.01, P <0.01). The clinical blood volume of Lhasa City Hospital from January 2010 to May 2015 was mainly B type and O type, accounting for 33.40% and 36.77% respectively. Conclusions The proportion of ABO blood type, B type and O type blood of unpaid blood donors in Lhasa from January 2010 to May 2015 is lower than that of clinical blood in Lhasa, which is the main reason for the shortage of blood supply; The proportion of Tibetan people who donate blood at their own expense and establish a safety mechanism of blood collection and blood supply are feasible measures to solve the long-term tension of type B and type O blood in Lhasa.
