Platelet storage

[Ref: KB2:p209-210; PK1:p254]

Storage condition

Temperature of storage

Platelets in stored bloods are stored at 4C
--> Irreversible disc-to-sphere transformation due to microtubule disassembly
--> Non-functional

Thus in stored blood, platelet function is poor or absent

Gas exchange during storage

Production of lactic acid and carbon dioxides lowers the pH

Thus, gas exchange (via special bag and constant mild agitation)
--> Promote aerobic metabolism
--> Minimise lactic acid production and promote loss of CO2

Risk of infection
