[Evaluation of Storage Performance of Preserving Bags for Manually Separated Platelets].

OBJECTIVE: To evaluate the storage performance of the domestically made platelet storage bags (experimental group) and the United States Trima set platelet storage bags (control group). METHODS: The manually separated platelets were divided in two equal parts, which was added to control blood bags and experimental blood bags respectively, all samples were stored at a 22 °C ± 2 °C. The platelet count, mean volume, aggregation activity (ADP, THR), pH, glucose, lactate concentration, lactate dehydrogenase concentration, hypotonic shock reaction, CD62P and phosphatidic acid serine content were detected at day 0, 3, 5 and 7 of storage. RESULTS: There was no significant difference of platelet quality at day 5 after storage between the experimental group and the control group (T-test, P > 0.05). CONCLUSION: Two kinds of platelet storage bags have the similar storage performance.
