INS and Hypokalemia: During insulin protocols, a total of 9/11 dogs (81.8%) in Group L and 10/13 dogs (76.9%) in Group R developed transient hypokalemia (<3.6 mEq/L), despite potassium supplementation; median minimum potassium concentrations did not differ significantly between Group L (3 mEq/L; range, 2.8–3.5 mEq/L) and Group R (2.8 mEq/L; range, 2.1–3.6 mEq/L; P = 0.32).
