Background Currently most studies on anaesthetic effects on hepatic blood flow of cirrhotic patients have been performed on adults or experimental animals. We performed this study to evaluate the effect of sevoflurane anaesthesia on hepatic blood flow in infants with obstructive jaundice by Doppler ultrasound. Methods Forty‐four infants with biliary atresia (1–3 months of age) scheduled for a Kasai procedure were enrolled. Hepatic blood flow was calculated by Doppler ultrasound measurements before induction, and after inhalation of 2% and 3% sevoflurane. Infants were allocated to three groups according to baseline portal blood flow/hepatic artery blood flow: group A (portal blood flow/hepatic artery blood flow < 1), group B (1 ≤ portal blood flow/hepatic artery blood flow < 2) and group C (portal blood flow/hepatic artery blood flow ≥ 2). Changes in portal blood flow, hepatic artery blood flow and hepatic blood flow were compared among groups. Results In group A ( n = 9), the median ( IQR ) hepatic blood flow increased after inhalation of 2% sevoflurane compared to that before induction (from 49.7 (32.0–89.0) to 116.1 (40.4–159.1) ml/min; P = 0.035). Whereas in groups B and C in whom the ratio of portal blood flow and hepatic artery blood flow was normal or mildly changed, the increases in hepatic blood flow after sevoflurane anaesthesia were not significant. Conclusions For infants with obstructive jaundice that had reduced portal blood flow and compensatory increase in hepatic artery blood flow, sevoflurane may produce a protective effect on hepatic blood flow.
