Our results showed that AKI patients had a significantly higher base excess (BE) at admission (p = 0.038), higher myoglobin levels at 48 h and 72 h (p < 0.001 and p = 0.023), more acidic urine pH at 48 h (p = 0.03), significant albumin use at admission, and a more positive fluid balance from 24 h to 72 h, compared to the no AKI cohort (p < 0.05). Here, MB is linked to acute kidney injury.
