Both systems showed increased %Hemolysis after infusion. The instruments were from the following companies: Baxter Healthcare Corp. (Deerfield, IL, USA) and Terumo Medical Corp. (Tokyo, Japan). Abbreviations: K, potassium; LDH, lactate dehydrogenase; plasma Hb, plasma hemoglobin; %Hemo, %Hemolysis; SD, standard deviation.
