[Platelet preservation in a new type of plastic material. Functional in vitro study].
We report the comparison of the fonctionnal platelet criteria's evolution studied in vitro by aggregation with different agents, by osmotic stress, ATP total amount and platelet volume distribution for six days of storage in two different PVC bags. The results indicate that: platelet's evolution appears more appreciable when tested by aggregation with an important amount of collagen, by hypotonic stress and volume distribution. The difference between the two different bags is shown as early as the thirs day of storage; for quality control, we can choose some criteria despite the absence of their clear correlation with transfusion efficiency.
