ABSTRACT: The objective of this study was to investigate the echocardiographic changes during anesthesia induction in dogs sedated with acepromazine (0.05mg/kg) and butorphanol (0.3mg/kg) (AB). Twenty-four male dogs, with a mean weight of 12.40kg±3.1kg, were randomly assigned to 4 groups (n=6). Fifteen minutes after administering pre-anesthetic medication, anesthesia with diazepam (0.5mg/kg) and etomidate (1mg/kg) (group DE); diazepam (0.5mg/kg) and ketamine (3mg/kg) (group CD); propofol (4mg/kg) (group P); or ketamine (1mg/kg) and propofol (3mg/kg) (group CP) was administered to the 6 dogs in each group. Systolic blood pressure (SBP) was measured and echocardiography was performed immediately prior to the application of the sedation protocol (baseline), 15 minutes after sedation (M1), and immediately after anesthesia induction (M2). No significant differences were observed in SBP and in hemodynamic variables such as cardiac index, shortening fraction, and ejection fraction, between groups at all time points (M0, M1, and M2) evaluated. The SBP was significantly reduced after anesthetic induction in the dogs of the DE and CP groups. It can be concluded that the protocols DE and CP reduce similarly to SPB in dogs medicated with CD and P to SBP remain stable after anesthetic induction. All anesthetic induction protocols maintained a stable IC in premedicated dogs. None of the protocols evaluated promoted significant echocardiographic changes. Furthermore, the ketamine and diazepam combination had a negative impact on myocardial relaxation.
