Abstract:
Objective To study the effects of environmental factors,including high temperature,high humidity and low temprtature,on the quality of whole blood.Methods Fresh blood was collected from 9 blood donors and divided into 40 parts.One group that comprised 20 samples was used to assess the effects of storage at high temperature and high humidity (0,3,6,12 and 24 h),and the other group(20 samples)was used to determine the effects of low temprtature(0,1,2 and 3 h).The serum free hemoglobin(FHb)concentration, plasma prothrombin time(PT), activated partial thromboplastin time(APTT),thrombin time(TT)and fibrinogen(FIB)were measured and analyzed.Results The high temperature(27-37℃)and humidity(60%-90%RH)had no effect on FHb, PT, APTT, TT or FIB of whole blood. The low temperature(0-13℃and -18--20℃)had some effect on the quality of whole blood.The FHb of test group was higher than that of control group.There was no significant difference in PT, APTT, TT and FIB between the two groups.Conclusion Under high temperature and humidity conditions, 24 hours of whole blood placement is feasible. Under low temperature or cold conditions,short-term whole blood placement is feasible in a tent with heating facilities.
