Since the initial blood examination showed renal dysfunction with mild CK and myoglobin elevation and a urinary test showed elevated β2-microglobulin and N-acetyl-β-D-glucosaminidase, markers of renal tubular damage (Table 1), we monitored CK and myoglobin levels in daily routine blood examinations during the ICU stay.
