Cardiovascular effects of propofol alone and in combination with ketamine for total intravenous anesthesia in healthy cats

Comparison between two methods for cardiac output measurement in propofol‐anesthetized dogs: thermodilution and Doppler

“…In this study, during the whole anesthesia procedure measurements of cardiac output as determined by CO TD, CO DP and CO DA were stable over time (Table 1). Quandt et al (1998), in dogs anesthetized with a single dose of propofol and using thermodilution, did not observe depressant effects of this drug on CO and showed stability of CO. Ilkiw & Pascoe (2003), in a study with cats anesthetized with a propofol infusion, concluded that this drug alone provided cardiopulmonary stability. Although Mason et al (2001) states that higher and lower CO influences the degree of agreement between methods, cardiac output values were stable in this study, thus the influence of the level of CO on the degree of agreement could not be determined.…”
