Abstract:
The aim of this study was to evaluate the accuracy of transtracheal doppler (TTD) cardiac output monitoring. Eleven mongrel dogs (weight: 8～15kg) were anesthetized with intravenous thiopental 20mg?kg~(-1), and the doppler tube was inserted into trachea and fixed at a proper position where clear signal was received, and the catheter with thermistor was passed into pulmonary artery via femoral vein. CO were measured simultanously by thermodilution (TD) and TTD in the basic state, during 10 mins after intravenous administration of propofol 2mg?kg~(-1), in 30 mins following intravenous dopamine 100?g?kg~(-1) or under condition of isovolumic hemodilution in sequence. The results demonstrated that the CO measured by TTD correlated positively with that by TD (r=0.88, P
