Abstract
New systems for collection of platelet concentrate (PC) and platelet poor plasma (PPP) are presently available. The aim of our work was to test the possibility of preparing PC routinely from normal plasma donors in a minimum amount of time and, at the same time, providing a second product that can be used as source-plasma or fresh-frozen plasma. Over a 3 year period (from 1990 to 1992) we performed 3503 procedures using 2 Haemonetics PCS machines (1236 procedures) and 3 Autopheresis-C (2267 procedures). With the PC produced we were able to satisfy all the requests coming from the hospitals of our region. The platelet yield was 1.95x10″ with PCS and 3.2x10″ with Auto-C in a PC volume of 150 and 200 ml respectively; collection times were quite similar (56 and 63 min). The results show that plasma-plateletpheresis is an efficient and competitive system. Regarding platelet yield, the best results were obtained with the Auto-C.
