title: Evaluation of microwave-thawed canine plasma for transfusion.
abstract: Units of fresh-frozen canine plasma were thawed rapidly in a microwave oven, using a mean of 15.4 thawing periods of 10 seconds each. The activated partial thromboplastin times, the one-stage prothrombin times, concentrations of fibrinogen, factor-VIII coagulant activity, and von Willebrand factor antigen of microwave-thawed units were not significantly different from those measured in small aliquots of the same units thawed in a warm water bath (n = 5). Five dogs were given a unit of their own microwave-thawed plasma. During the 24 hours after infusion, no significant changes were measured in temperature, heart rate, or respiration rate. In addition, significant changes in PCV, total protein concentrations, estimates of platelet numbers, total RBC counts, total WBC counts, and differential WBC counts were not measured in blood specimens obtained before infusion and 24 hours after the infusion of microwave-thawed plasma.
