EFEITOS HEMODINÂMICOS DA INFUSÃO CONTÍNUA DE BUTORFANOL EM CÃES ANESTESIADOS COM PROPOFOL HEMODINAMIC EFFECTS OF CONTINUOUS RATE INFUSION OF BUTORPHANOL IN PROPOFOL-ANESTHETIZED DOGS

Le résumé fourni par la source

The aim of this study was to evaluate the hemodynamic effects of the total intravenous anesthesia with propofol and butorphanol in dogs. For that purpose, twenty adult healthy crossbred dogs were used. The animals were equally allocated into two groups (PG and BG) and induced to the anesthesia with intravenous propofol (10 mg/kg). After orotracheal intubation, controlled ventilation was instituted with 60% oxygen and flow of 30 mL/kg/min in a closed system, with controlled volume. The anesthetic maintenance was accomplished with propofol (0.6 mg/kg/min). The butorphanol group (BG) received, butorphanol 0.1 mg/kg IV, followed by continuous infusion (40 µg/kg/h). The placebo group (PG) received only NaCl 0.9% in bolus, followed by venous infusion, in identical volume of
