Studies of the minimum temperature at which human platelets can be stored with full maintenance of viability.

Platelet concentrates from normal donors were stored for 3 days under identical conditions except for the temperature of storage, which was maintained at 21 +/- 0.5, 19.5 +/- 0.

Extended storage of platelets in a new plastic container. II. In vivo response to infusion of platelets stored for 5 days.

A new blood container material (PL 1240 plastic) made of polyvinyl chloride containing a tri(2-ethylhexyl) trimellitate plasticizer was evaluated in three laboratories. When platelet concentrates (50-60 ml) were stored on a variety of agitators for 7 days at 22 +/- 2 degrees C, poststorage pH (mean +/- SD) ranged from 7.29 +/- 0.

Use of Adsol preservation solution for prolonged storage of low viscosity AS-1 red blood cells.

A new red cell preservation solution is described in which the red cells may be stored for 49 d with greater than 75% mean post-transfusion recovery. Blood is drawn into Anticoagulant Citrate Phosphate Dextrose Solution, centrifuged, the plasma removed and the cells resuspended in 100 ml of a solution containing saline, adenine, dextrose and mannitol (Adsol Preservation Solution, Fenwal Laboratories, Deerfield, Illinois). The final product, AS-1 Red Blood Cells, has a haematocrit of approximately 0.

Importance of white blood cells in platelet storage.

Platelet concentrates from 290 healthy donors collected in CPD anticoagulant and PL-146 polyvinylchloride containers were stored for 72 h at 22 +/- 0.5 degrees C under standard conditions to investigate variables affecting the quality of stored platelets. In addition to the expected inverse relationship between pH and platelet count (p less than 0.
