Case C: Cr decrease . Plasma creatinine changes (a) and fluid input/urine output and plasma volume (b) are shown. Fluids alone cannot account for the reduction in plasma creatinine (grey line). Either glomerular filtration rate (GFR) must be assumed to increase dramatically followed by a decrease (dotted or lines) or there is a rapid reduction in plasma creatinine production (black lines) (see 'Case C: Crdecrease' subheading). Crdecrease, group of patients with a plasma creatinine decrease of more than 10% at 24 hours after cardiac arrest.
