Studies to Improve Techniques of Platelet Preservation.

摘要

Platelet storage at room temperature showed a minimal loss of viability over a 72hour storage interval for both ACD and CPD collected units prepared by the Mourad Technique. Freshly prepared Mourad resuspended platelet concentrates had a viability index of 0.77compared to 0.63for ACD and CPD stored units,respectively. Platelet concentrates stored at 33 C for only 24hours gave recoveries so low,post-transfusion reliable survival data could not be calculated. In other studies, a correlation was established between bleeding time as an in vivo measure of platelet function and of platelet count and selected thrombocytopenic patients. Also,fecal blood loss has been used as a measure of platelet function.
