Hemodynamic effects of butorphanol in desflurane-anesthetized dogs.

Objective: To evaluate the effects of butorphanol on cardiopulmonary parameters in dogs anesthetized with desflurane and breathing spontaneously.

Study Design: Prospective, randomized experimental trial.

Animals: Twenty dogs weighing 12 ± 3 kg.

Partial external mitral annuloplasty in dogs with myxomatous mitral valve degeneration and congestive heart failure: outcome in 9 cases.

Objective: To report the outcome of partial external mitral annuloplasty in dogs with congestive heart failure (CHF) due to mitral regurgitation caused by myxomatous mitral valve degeneration (MMVD).

Animals, Materials And Methods: Nine client-owned dogs with CHF due to mitral regurgitation caused by MMVD. Surgery consisted of a double row of pledget-butressed continuous suture lines placed into the left ventricle parallel and just ventral to the atrioventricular groove between the subsinuosal branch of the left circumflex coronary artery and the paraconal branch of the left coronary artery.

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

Objective: To compare cardiac output (CO) measured by Doppler echocardiography and thermodilution techniques in spontaneously breathing dogs during continuous infusion of propofol. To do so, CO was obtained using the thermodilution method (CO(TD)) and Doppler evaluation of pulmonary flow (CO(DP)) and aortic flow (CO(DA)).

Study Design: Prospective cohort study.

Bispectral index in dogs at three intravenous infusion rates of propofol.

Objective: To establish the correlation between the bispectral index (BIS) and different rates of infusion of propofol in dogs. Study design Prospective experimental trial.

Animals: Eight adult dogs weighing 6-20 kg.
