Abstract: |
BACKGROUND: Cryoprecipitate helps in replenishing important coagulation factors like fibrinogen, Factor VIII and von Willebrand factor without running the risk of volume overload. It is very useful in the treatment of trauma patients with active bleeding and works best when administered early. Extending the shelf life of thawed cryoprecipitate beyond 4 hours enables us to manage inventory better, reduces the burden of demand vs supply as well as minimizes wastage. It can also help in logistically supporting the transfusion services in making cryoprecipitate readily available in mass casualty scenarios (war, natural calamity) in remote locations by reducing the time required for thawing cryoprecipitate and the need for costly storage equipment. AIM: The aim of this study was to compare the levels of Factor VIII, Fibrinogen and von Willebrand factor on thawed cryoprecipitate after prolonged storage for 5 days at a temperature of 2-6°C. METHODOLOGY: The above mentioned coagulation factors were analyzed in cryoprecipitate at the time of product thaw and again after 120 hours of 2 to 6°C storage using fully automated coagulation analyser (STA Compact Max). All parameters were expressed as Mean ± Standard deviation and were analyzed using paired t test with level of significance, P < 0.05. RESULTS: There was a significant decrease in the level of Factor VIII, whereas the levels of fibrinogen and von Willebrand Factor remained stable during the storage period. All the cryoprecipitate units retained factor activities above therapeutic range even after 5 days of storage at 2-6°C. CONCLUSION: Although the levels of clotting factors are reduced during storage, they are still maintained above the therapeutic range. In scenarios where maintaining frozen cryoprecipitate inventory is a logistical challenge and emergency massive demands of cryoprecipitate are foreseen, the use of pre-thawed cryoprecipitate can be considered as a viable option.
