• To evaluate hepatic function, the kinetics of indocyanine green clearance were studied in seven injured patients with hepatic venous catheters. Indocyanine green clearance after a bolus injection of 20 mg was relatively monoexponential on the first day after injury. Following this, a second slower compartment of indocyanine green clearance was uniformly evident, becoming most prominent around the fourth day after injury. Indocyanine green clearance again became more uniform as recovery continued. Fractional indocyanine green extraction ten minutes after injection decreased from 0.9 on the first day after injury to 0.2 three days later, and then returned to 0.7 on the seventh day after injury. These decreases in indocyanine green clearance preceded an increase in total serum bilirubin concentration to a mean value of 1.9 mg/dL. Indocyanine green clearance was thus found to be an early and sensitive indicator of impaired hepatic function.
