RESUMO
Objective To evaluate the quality of cryoprecipitates prepared from fresh frozen plasma via deepfreeze method and siphonage method thawing at 4℃ water bath,and to select a proper preparation method for cryoprecipitates.Methods Sixty samples of cryoprecipitate prepared by deepfreeze method,and 60 samples of cryoprecipitate prepared by siphonage method were selected randomly.Factor FⅧ,fibrinogen(Fg) in cryoprecipitates were measured by coagulometer,and the qualification rates were calculated.Results The concentration of FⅧ(IU/pack) in the cryoprecipitates prepared via deepfreeze method and siphonage method were(70.30?23.68),and(161.62?39.45),respectively;the qualification rate of FⅧ prepared via the two methods were 43.33%(26/60),and 93.33%(56/60),respectively(P0.05).Conclusion Siphonage method,with a higher qualification rate of FⅧ,is simple and fast,which deserves a popular application.
