Abstract |
Portal bood flow was measured with pulsed Doppler ultrasound in twenty anesthetized dogs. In anesthetized dogs with xylazine HCl, the average of portal blood flow velocity was reduced($11.68{pm}1.55cm/sec$ vs. normal $16.67{pm}1.77cm/sec$). Average portal blood flow was also decreased compared to normal($28.36{pm}11.61ml/min/kg$ vs. normal $43.12{pm}14.46 ml/min/kg$). And congestion index was increased($0.0368{pm}0.0117cm{cdot}sec$) vs. normal $0.0297{pm}0.0062cm{cdot}sec$). In anesthetized dogs with ketamine HCl, portal blood flow velocity was slightly increased ($22.62{pm}2.53cm/sec$ vs. normal $16.67{pm}1.77cm/sec$. Also mean portal blood flow was slightly increased($43.12{pm}14.46ml/min/kg$ vs. normal $55.32{pm}19.99ml/min/kg$). In anesthetized dogs with tiletamine and zolazepam, portal blood flow velocity and portal blood flow were unchanged. |
