机采血小板无偿献血者初筛脂浆血分析

目的:分析机采血小板无偿献血者初筛脂浆血可能原因,实施干预对策,以保证血液质量,充分利用血液资源.方法:自2011年1月25日至10月25日期间,对参加机采血小板无偿献血者初筛检验血型、ALT、HBsAg、PLT、血常规.对合格者将含抗凝剂的全血标本离心后,肉眼观察上清液是否属脂浆血.对脂浆血者,通过询问其饮食情况给予干预,并再次采抗凝全血标本离心,根据肉眼观察结果判断能否采集机采血小板.结果:共8 827人次献血者参加了机采血小板采前初筛检测,初筛脂浆血者769人,占总人次8.71％.可能原因为4～6h内进食高脂肪、高热量饮食(占67.36％),10 ～ 12 h内进食高脂肪、高热量饮食(占24.58％),脂肪代谢障碍(占8.06％).最终因脂肪血淘汰182人,初筛脂浆血者成功采集率76.33％.结论:通过对机采血小板无偿献血者初筛脂浆血可能原因分析,并实施干预措施,大多数初筛脂浆血者都能成功采集机采血小板,干预措施对于更好地利用血液资源是有效的.

Analysis of Screening Plasma Lipid in Unpaid Blood Donors of Platelets

Objective:To analyse the reason of screening lipid plasma with apheresis in platelet donors,implementation of intervention measures,to guarantee the quality of blood,to make full use of blood resources.Methods:From January 25,2011 to October 25,the platelet donors participated in the apheresis had ALT,HBSAg,PLT,and whose blood were qualified with anticoagulant,lipid plasma were observed in supernatant by naked eye after centrifugation.On the lipid plasma,the intervention were given after asking the diet,collected anticoagulated blood samples by centrifugation again,based on visual observation determined whether the the platelet were collected by machine.Results:A total of 8827 platelet donors attended the apheresis before detection screening,screenned lipid plasma with 769 peoples,the total number was 8.71%,the possible reasons were eating a high fat,high calorie diet before the 4-6 hours(67.36%),eating a high fat,high calorie diet before 10-12 hours(24.58%),fat metabolism disorder was 8.06%.The final,182 people of fat blood were eliminated,collection success of screening lipid plasma was 76.33%.Conclusion:By intervention measures,after screening lipid plasma of blood donors,acquisition of apheresis platelets can be successful,intervention strategies is the effective for better use of blood resources.
