Estimation of portal blood flow using pulsed doppler ultrasound in the anesthetized dog

도플러 초음파를 이용한 개에서 마취에 따른 간문맥 혈류량 변화의 측정

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.
