Reliability of microwave heating for hemoderivative thawing.

The spoiling of coagulation factors, proteic patterns and specific activity has been comparatively determined in fresh frozen plasma, cryoprecipitates and hemodiagnostic sera, thawed in a 37 degrees C water bath and in a microwave oven. Effects of conventional and microwave heating are not significantly different, while results of the latter technique are rapid and aseptic. Previously, heating performances of a commercial microwave oven have been investigated for deionized water, saline solutions, and bovine serum. Furthermore, plastic containers of hemoderivatives have been tested to assure that no toxic products are released during microwave heating.
