Abstract:
Objective:To evaluate the effect of different concentrations of sevoflurane inhalation anesthesia on hepatic blood flow in children with hepatoblastoma (HB).Methods:A total of 22 children who underwent radical resection of HB in Shanxi Children's Hospital from January 2019 to August 2021 were perspectively enrolled, including 15 males and 7 females, with an average age of 17±7 months. There were 19 normal children undergoing ultrasound examination without other systemic diseases who received hernia, cryptorchidism, hydrocele of tunica vaginalis surgery during the same period, including 11 males and 8 females, with an average age of 18±5 months. After inhaling different concentrations of sevoflurane preoperatively and intraoperatively, ultrasound apparatus was used to detect the hepatic blood flow (HBF) in HB children. The portal blood flow (PBF), hepatic artery blood flow (HABF), PBF/HABF and HBF were compared between HB children and non-HB children before operation and after inhalation of 1% sevoflurane, 2% sevoflurane.Results:Compared with non-HB children, children with HB had lower PBF [41.9 ml/min (26.8 ml/min, 63.1 ml/min) vs. 66.7 ml/min (41.4 ml/min, 137.2 ml/min), Z = -2.62, P = 0.008], increased HABF [31.2 ml/min (20.4 ml/min, 50.3 ml/min) vs. 12.9 ml/min (5.5 ml/min, 25.0 ml/min), Z = -3.59, P < 0.001], decreased PBF/HABF [1.3 (1.2, 1.4) vs. 6.1 (5.0, 7.5), Z = -5.68, P < 0.001], and the difference in HBF between the both groups was statistically significant ( P>0.05). Compared with the 2% sevoflurane HB group, PBF was reduced [41.1 ml/min (25.0 ml/min, 62.0 ml/min) vs. 63.0 ml/min (40.5 ml/min, 78.3 ml/min), Z = -2.09, P = 0.036] and PBF/HABF was reduced [1.3 (1.1,1.5) vs. 1.8 (1.6, 1.9), Z = -4.01, P<0.001] in the 1% sevoflurane group, and the differences in HABF and HBF were statistically significant (all P>0.05). Conclusion:Relatively low concentration of sevoflurane reduces HBF by reducing PBF for HB children after radical surgery.
