目的单采血小板间隔时间由4周缩短至2周,探讨频繁捐献血小板对献血者外周血血常规的影响。间隔期缩短至2周,并且每年献血24次后对献血者血常规的影响。方法 2013年9月-2015年10月,间隔2周采集1次血小板,1年捐献血小板24次的献血者,观察分析每次捐献前外周血血常规参数。结果 58名献血者间隔2周捐献1次血小板,24次捐献前外周血血常规有一定的波动。Plt和RBC,第1次与第24次之间差异无统计学意义(P>0.05),Hct、Hb和WBC,第1次与第24次之间差异有统计学意义(P<0.05)。结论机采血小板献血间隔期短至2周后,献血者血常规值在正常范围内波动,需要增加观察的时间,以确保献血者的安全。
Objective The apheresis platelet interval was shortened from 4 weeks to 2 weeks to explore the impact of frequent donation of platelets on the peripheral blood of blood donors. The interval is shortened to 2 weeks, and blood donations 24 times a year after the impact on blood donors. Methods From September 2013 to October 2015, blood donors were collected once a week for 2 weeks and donated 24 times a year for 1 year. Peripheral blood parameters before each donation were observed and analyzed. Results Fifty-eight blood donors donated 1 platelet 2 weeks apart. Before the 24 donations, there was some fluctuation in blood routine. Plt and RBC. There was no significant difference between the 1st and 24th (P> 0.05), Hct, Hb and WBC, between the 1st and the 24th (P <0.05). Conclusion After blood donation interval of blood platelet is as short as 2 weeks, the blood routine value of blood donor fluctuates within the normal range, and the observation time needs to be increased to ensure the safety of blood donors.
