Abstract:
Objective To investigate the effects of temperature and time on the quality of cryoprecipitate.Methods Fresh frozen plasmas were divided into the three groups,and the cryoprecipitate were prepared from fresh frozen plasma by siphonage method thawing at 2℃,4℃ or 6℃ water bat.Thawing time,FⅧ and fibfinogen (Fg) were compared among the three groups.Results The thawing time at 2℃,4℃ or 6℃ was (96.3 ± 5.9) min,(89.6 ± 4.3) min,(81.2 ± 2.7) min.The activity of F Ⅷ was (95.36 ± 4.8) IU,(91.21 ± 3.3) IU,(89.8 ±3.1)IU,respectively.The activity of FⅧ was the highest at 2℃ condition and there was significantly different compared with other two groups (t =6.94,P =0.009,t =8.96,P =0.004).The activity of FⅧ in 4℃ group and 6℃ group were comparable (t =0.669,P =0.19).The concentration of Fg at three groups were similar (258.6 ±12.6) mg,(253.3 ±8.2)mg,(255.9 ±9.7) mg (t =0.321,P =0.37;t =0.270,P =0.56;t =0.424,P =0.29).Conclusion The activity of FⅧ at 2℃ condition were the highest but the thawing time was the longest.The activity of FⅧ at 6℃ condition were lower but met quality requirements and the thawing time was very short.There was no significantly different at Fg concentration among three groups.Thus 6℃ is more suitable for blood center to prepare cryoprecipitate from fresh frozen plasmas.
