Hepatic blood flow in humans during isoflurane-N2O and halothane-N2O anesthesia

Hepatic blood flow (HBF) (assessed by plasma clearance and hepatic extraction of indocyanine green), cardiac index, and hepatic venous oxygen saturation were measured in patients before and after induction of anesthesia with thiopental, fentanyl, and N 2 O, and again during halothane (1 MAC)-N 2 O (n=5) or isoflurane (1 MAC)-N 2 O (n=6) anesthesia before the start of surgery
