Abstract
Objective To explore the correlation between blood cell parameters of blood donors and platelet collection volume of blood cell separator. Methods From January to July, 2018, 79 volunteers with platelet counting from 281×109/L to 330×109/L were selected as a study group, and 79 volunteers with platelet count from 230/L×109 to 280×109/L were selected as a control group. The general data of the two groups were recorded. The blood cell parameters (platelet count Plt, hemoglobin concentration Hb, blood volume BV, hematocrit HCT) and collection parameters (collection time, total blood volume) of the two groups were counted, and the relationship between these parameters and platelet collection volume was analyzed. The collection efficiency of platelet and the incidence of adverse reactions of the blood donors were calculated. Results There were no statistical differences in height, weight, and BMI between the study group and the control group [(65.85 ± 9.93) kg vs. (67.29 ± 11.37) kg, (1.68 ± 2.37) m vs. (1.66 ± 1.21) m, and (23.33 ± 1.77) kg/m2 vs. (24.42 ± 7.76) kg/m]. The platelet count was higher in the study group than in the control group [(298.30 ± 16.29)×109/L vs. (245.90± 12.38)×109/L, P < 0.05]. The hemoglobin concentration was significantly higher in the control group than in the study group [(148.73 ± 13.22) g/L vs. (128.75 ± 12.82) g/L, P < 0.05]. The blood volume and the specific volume of blood cells were (4.77 ± 2.15) L and (46.01 ± 3.17)％ in the study group, and were (4.75 ± 0.27) L and (45.68 ± 6.32)％ in the control group, with no statistical differences (both P > 0.05). The correlation between hemoglobin concentration and platelet collection volume was analyzed, and there was a negative correlation between hemoglobin concentration and platelet collection volume. The incidence of adverse reactions was 0.09％ in the study group, and 0.12％ in the control group (P > 0.05). Conclusion There is a negative correlation between hemoglobin concentration and platelet collection volume.关键词
