Study of Single Donor Platelet (SDP) Preparation by Baxter CS 3000 plus and Haemonetics MCS plus

In plateletpheresis blood is withdrawn from a donor in anticoagulant solution and separated into components. Platelets are retained and the remaining components are returned to the individual.

The present study was aimed to compare the platelet yield and collection efficiency of Baxter CS 3000 plus and Haemonetics MCS plus cell separators and to study adverse donor reactions. Donors were selected as per the set criteria for single donor platelet (SDP) preparation. Donors' samples for pre donation and post donation platelet count were collected in EDTA and for product counts in the sample pouch attached with apheresis kits. The results were obtained by haematology analyzer. Platelet yield and collection efficiency were calculated.

Results were tabulated for both the cell separators and analyzed. Platelet yield was marginally better with Baxter CS 3000 plus but collection efficiency was better with the Haemonetics MCS plus. Residual white cells were more in single donor platelet concentrate preparation by MCS plus. Adverse donor reactions were similar with both cell separators, in form of mild citrate toxicity and mild to moderate pain at phlebotomy site.

Findings of the present study along with other factors such as less priming time for kit, portability of cell separator, better patient comfort owing to single arm venous access and lesser cost suggest that Haemonetics MCS plus is a better choice as compared to Baxter CS 3000 plus cell separator.
