| The effects of inspired oxygen fractions (FiO2) of 1 and 0.6 on bispectral index (BIS) in dogs with high intracranial pressure, submitted to a continuous rate infusion of propofol were evaluated. Eight dogs were anesthetized on two occasions, receiving, during controlled ventilation, an FiO2 = 1 (G100) or an FiO2 = 0.6 (G60). Propofol was used for induction (10mg.kg-1, IV), followed by a continuous rate infusion (0.6mg.kg-1.minute-1). After 20 minutes, a fiber-optic catheter was implanted on the surface of the right cerebral cortex to monitor the intracranial pressure, the baseline measurements of BIS values, signal quality index, suppression ratio number, electromyogram indicator, end-tidal carbon dioxide partial pressure, mean arterial pressure,... |

| ABSTRACTThe cardiopulmonary changes in propofol- or thiopental-anesthetized dogs induced to pulmonary hypertension (PH) were evaluated. Twenty adult animals were randomly assigned to two groups: propofol group (PG) and thiopental group (TG). In PG, propofol was used for induction (8(0.03mg.kg-1) and anesthesia maintenance (0.8mg.kg-1.minute-1), while, in TG, thiopental was used (22±2.92mg.kg-1; 0.5mg.kg-1.minute-1, respectively). Mechanical ventilation using time cycle was started. PH was induced by administration of serotonin (5HT) (10µg.kg-1 and 1mg.kg-1.hour-1) through a thermodilution catheter positioned in the pulmonary artery. The measurements were performed before administration of 5HT (T0), after 30 minutes (T30), then at 15-minute intervals (T45,... |

| It was studied fortuitous cardiorespiratory and bispectral index changes in dogs anesthetized with isoflurane associated or not to tramadol. Sixteen dogswere distributed in two groups named CG (control group) and TG (tramadol group). General anesthesia was induced in all animals with isoflurane via mask. After 10 minutes, the animals of CG received 0.05ml/kg of saline solution at 0.9%, and TG received 2mg/kg of tramadol, both via intramuscular. It was evaluated heart rate, systolic, diastolic and mean arterial pressures; electrocardiography; respiratory rate; oxihemoglobin saturation; end tidal carbon dioxide; bispectral index and recovery of anesthesia. The administration of tramadol in dogs anesthetized with isoflurane did not produce changes in... |
