Figure 1 Mean individual change in serum creatinine at 48 h in the control group and the two subsets of the experimental group. IVF = intravenous 0.45 normal saline at 150 ml/h for 6 h with upward adjustment for urine flow rates greater than 150 ml/h (control group). F = furosemide 1 mg/kg intravenously up to 100 mg at the start of the procedure. D = intravenous dopamine 3 mcg/kg/min at the start of the procedure and continued for 6 h. M = mannitol 12.5 g in 250 ml of 5% dextrose infused at the start of the procedure over a 2-h period. p = 0.21 by analysis of variance.
