Causes and preventive measures of lipemic blood in voluntary blood donors / 中国输血杂志

ABSTRACT

【Objective】 To analyze the causes and preventive measures of lipemic blood in voluntary blood donors. 【Methods】 Data of 12 000 voluntary blood donors donated at our blood station from January 2018 to June 2020 were retrospectively analyzed. The incidence, discarding rate and causes of lipemic blood were investigated, and preventive measures were formulated. 【Results】 384(3.20%) out of the 12 000 blood samples were lipemic blood, while mild, moderate and severe lipemic blood constituted 181, 148 and 55 cases, respectively. The incidence of lipoemia in males(4.22%) was higher than that in females(1.52%). The incidence of lipoemia in 26~45 and 36~45 age population was 4.75%, which was higher than that in 18~25 age group(0.62%). The incidence of lipoemia was the lowest in donors with mass index(kg/m2) <18.5, followed by 18.5~24.9 and >30 (P<0.05). The incidence of lipemic blood among first-time blood donors(4.38%) was higher than that in repeated donors(2.31%), higher in blood donation collected during 13 00 to 17 00(3.54%) than 9 00 to 12 00 a. m.(2.73%), also higher in group blood donors(4.01%) than street blood donors(1.56%)(P<0.05). The free Hb of red blood cells in moderate and severe group was higher than that in mild group immediate after preparation and 7 days after preparation (P<0.05). 【Conclusion】 There was a significant tendency for the incidence of lipemic blood in voluntary blood donors, which causes blood discarding. The publicity of blood donation, pre-donation consultation and advice on reasonable diet should be boosted to reduce the discarding rate of lipemic blood and improve the use of blood.
