[Studies of thrombocyte function in CPD blood]

G Frick, U Frick, S Preussner

    Folia Haematologica (Leipzig, Germany : 1928)
    |January 1, 1978
    PubMed
    Summary

    Storing platelet-rich plasma with CPD stabilizer at room temperature for 3 days significantly impairs thrombocyte function. Refrigeration at 4 degrees C preserves some function, with pH influencing the loss.

    Area of Science:

    • Biochemistry
    • Hematology
    • Blood Storage

    Context:

    • Platelet-rich plasma is crucial for hemostasis.
    • Effective blood storage requires preserving platelet function.
    • CPD stabilizer with adenine sulfate and guanosine is used for erythrocyte preservation.

    Purpose:

    • To investigate the preservation of global thrombocyte function in platelet-rich CPD plasma during storage.
    • To evaluate the impact of storage temperature (4°C vs. room temperature) on thrombocyte function over 3 days.

    Summary:

    • Platelet-rich CPD plasma was stored for 3 days at 4°C or room temperature.
    • Thrombocyte function, assessed by the DKTA method (aggregation-adhesion), was significantly reduced at room temperature.
    • Storage at 4°C offered partial preservation of thrombocyte function, with pH being a critical factor.

    Impact:

    • Demonstrates the detrimental effect of room temperature storage on platelet function in CPD plasma.
    • Highlights the importance of temperature control in blood product storage for maintaining hemostatic capacity.
    • Suggests that pH significantly influences thrombocyte function loss during storage.
