Effect of Donor Parameters on the Yield of Plateletpheresis by Intermittent Flow Cell Separator. Annals of International medical and Dental Research. 2018 Mar; 4(2): 27-302395-28222395-2814http://imsear.searo.who.int/handle/123456789/188550Background: Platelet Transfusion are used for the treatment and prevention of bleeding in patients with decreased number and function of platelets. Platelet for transfusion can be provided by platelet concentrates, which are obtained either by PRP or buffy coat method from whole blood or by apheresis. Platelet Recovery in a patient is influenced by the transfused dose of platelets which in turn is dependent on the platelet yield. Aim of Study: In this study, our main objective is to identify the donor parameters that influence the platelet yield obtained by apheresis.Methods: This prospective study was undertaken in the Department of IHBT.140 healthy donors were selected for plateletpheresis according to guidelines laid down by Drugs and cosmetics Act over a period of one year. The plateletpheresis procedures were performed on Haemonetics MCS plus separator. Yield predicting donor variables included in the study were Age, Gender, Haemoglobin concentration, Haematocrit and Platelet count. The relationship between predonation donor variable and yield was studied using pearson correlation. Results: The Mean platelet yield was 3.19±0.48×1011per unit. Mean predonation platelet count of donor was 2.77± 0.46×105/μl. Mean age of the Donor was 30.31±8.14. Positive Correlation was observed between platelet yield and predonation platelet count of donor(r=0.318, P value 0.0001) which is significant. No such correlation was seen between platelet yield and Haemoglobin(r=0.131, P value 0.122), Haematocrit (r=0.058, P value 0.499), Age of Donor(r=0.034, P value 0.692). Conclusion: The possibility of obtaining higher platelet yield reduces the frequency of platelet transfusion and number of donor exposures with important consequent clinical and economic advantages.Journal ArticleIndiaMD Pathology, Associate Professor, Department of Immunohematology and Blood Transfusion, GGSMCH, FaridkotPG Resident 3rd year, IHBT, Department of Immunohematology and Blood Transfusion, GGSMCH, Faridkot.MD, Pathology, Prof. and Head, Department of Immunohematology and Blood Transfusion, GGSMCH, Faridkot.MD IHBT, Demonstrator, Transfusion medicine,Department of Transfusion Medicine, GMCH 32 Chandigarh.MD IHBT, Senior resident, Transfusion medicine, Department of Transfusion Medicine, AIIMS Jodhpur.PG Resident 2nd year, IHBT, Department of Immunohematology and Blood Transfusion, GGSMCH, Faridkot.
