Abstract

Background and Objective: Component preparation is the backbone of blood centre services. Every blood centre follows standard operative techniques, for component preparation and accepts units with match quality uses for patient services. For component preparation units specific equipment named a refrigerated centrifuge machine is used, which works on the principle of centrifugal force and centripetal force. The best programming defined the above quality standard for every separated unit. The objective of the above study is the evaluation of programming of component preparation over centripetal, centrifugal forces acceleration, and deceleration with time intervals.  Selection for the best program, which would matches the standard.

Materials and Methods: The study was observed over two different highly specialized equipment refrigerated cytocentrifuge machines known as (Rota Silenta and Thremofisher centrifuge), they are programmed for component preparation. Various programming followed by their Acceleration, Deceleration, Mid-interval Time, RPM, RCF, and Gravitational force,(G) were studied. Prepared products (PRBC, FFP, PC and WBC), their quality frequency was checked with a Fully Automated Hematology Analyzer evaluated.

Results: HERAEUS CRYOFUGE 16 Centrifuge results outcome was better compared to ROTA SILENTA 630 RS. The best programming of Heraeus croyofuge ACCELERATION (8) mins, DACCELARTION (8) mins and mid-interval (3) mins RPM,2350 and 3450 of 30 cm radius G Computed RCF was 2096 and 4018 noted. The above programming gives the best yield of platelets-287ug/dl, least contamination of FFP of RBC (.01) and platelets (24) ug/dl, prepared PRBC was HCT (69%), RBC was (9.6) ug/dl, and platelets contamination was (186) ug/dl. Among ROTA SILENTA best programmed was Acceleration (8), MID-Interval (3) and Deceleration (4) mins at RPM (2190,3250) with radius ( 29.5) cm along  G computed RCF(1342,3018)noted respectively, which gave best product after processing.

Conclusion: Section of best programming meets the quality standard and produces the best efficacy in terms of platelets preparation (yield), (hematocrit)-and PRBC preparation. Prepared FFP was less contaminated with RBC and matched with the defined log reduction of WBC. The selection of programming can enhance the quality criteria and meet the above standard product.
