System Reveos w świetle innych metod rozdziału krwi pełnej na składniki – porównanie badań kontroli jakości

Abstract

Background One of the elements that makes up blood safety is automation of processing whole blood into ingredients In 2017, Reveos was installed in Blood Bank in Lodz. By combining the centrifuge function and the press, Reveos provides full automation of the whole blood separation process, minimizing the risk of human error, thus ensuring accuracy and repeatability. The aim is to compare the results of the quality control of ingredients obtained after the blood separation using the Compomat G5, Optipress II and the Reveos system as well as to compare the level of compliance with the recommendations on the quality of blood components contained in the applicable regulations. Materials and methods 150 units were separated into ingredients using above mentioned systems showing choosen parameters. Results Parameters were determined for Compomat, Optipress i Reveos: plasma: volume 260±13ml, 262±14ml i 239±20ml, platelets: 16, 23 i 23x109/l. RBC: volume 286±13ml, 272±13ml i 295±17ml, hemoglobin 55, 51, 58g/unit., hematocrit 59, 58 i 52%, leukocytes 0,6x109/unit., 0,6x109/unit., 0,1x106/unit. Buffy coat volume: 56,6ml i 56,1ml for Compomat i Optipress and interim platelets volume 37,8ml. The platelet content in the above-mentioned components was 0.8, 0.7, 0.66x1011/unit, respectively. Conclusions The comparison of the quality of ingredients after the blood separation showed slight differences in the parameters determined. The main difference concerns the volume of the obtained plasma and red blood cells. Nevertheless, all the ingredients obtained meet rigorous quality control assumptions and separation methods can be successfully used in routine work. The Reveos system allows to obtain qualitatively good ingredients in a one-step process. This reduces staff interference in the whole process, which may result in minimizing errors during processing of the whole blood.
