Abstract

Aims: The aim of the study is to determine the optimal parameters of single centrifugation for the preparation of platelet-containing plasma (PCP) with maximum reduction of other cellular elements of the blood. Materials and Methods: 30 conditionally healthy persons aged 18 to 60 years (36.9±11.2 years) were included in the study. A total of 12 centrifugation modes were studied: 110g × 5 min, 110g × 10 min, 110g × 15 min, 140g × 5 min, 140g × 10 min, 140g × 15 min, 160g × 5 min, 160g × 10 min, 160g × 15 min, 190g × 5 min, 190g × 10 min, 190g × 15 min. To evaluate the effectiveness of different centrifugation modes, in addition to the number of basic cellular elements, such indicators as platelet capture efficiency, platelet enrichment factor, erythrocyte-reducing efficiencies and leukocyte-reducing efficiencies were studied. Results: When examining the volumes of the obtained plasma containing platelets, it was found that almost all centrifugation modes allow obtaining significantly different volumes of the investigated blood fraction from the others (p<0.001). For clarity, the regimens were sorted according to the volume of platelet-containing plasma obtained, from the smallest to the largest. There was a progressive decrease in the numerical values of the concentration of platelets, erythrocytes and leukocytes in plasma samples. Also there was a progressive decrease in the numerical values of the coefficient of platelet enrichment. Conclusions: With a single centrifugation for the preparation of plasma containing platelets, the most effective mode is 160g × 10 min, which allows achieving a platelet enrichment factor of about 1.71 at a platelet concentration of 483.6 ± 45.4 × 109/l, a platelet capture efficiency of 85, 7 ± 0.1% and reductions of erythrocytes and leukocytes 98.76 ± 0.09% and 98.46 ± 0.14%, respectively.
