There was a strong negative relationship between creatinine clearance and mortality. Of the 23 patients with a severe reduction of creatinine clearance (<20 mL/min), 17 died. In contrast, 23 of the 24 patients with a creatinine clearance of 100 mL/min or more survived. Urine output, BUN, and serum creatinine levels correlated poorly with creatinine clearance. A urine output of less than 30 mL/hr, a BUN level greater than 40 mg/dL, and a serum creatinine level greater than 2.0 mg/dL in all instances were associated with reduced creatinine clearances. However, more than half of all the patients with a normal urine output, BUN, or serum creatinine levels also had a reduced creatinine clearance.(Arch Surg 114:461-467, 1979)
