a A: potassium chloride concentrate 1 g (13.4 mmol) in 10mL injection, B: 20 mEq potassium chloride in 0.9% sodium chloride injection 1 L, C: 40 mEq potassium chloride in 0.9% sodium chloride injection 1 L, D: 20 mEq potassium chloride in 5% dextrose injection 1 L. bAmong the 296 cases using potassium chloride injections, 181 cases had records for serum potassium levels after potassium chloride injection administration. c Among the 296 cases using potassium chloride injections, 76 cases had records for time to reach eukalaemia or reversal of hypokalaemia symptoms.
