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,... |

Early identification of arrhythmias in dogs showing doxorubicin-induced cardiomyopathy was studied. Ten healthy dogs were assigned to groups A (n=5) and B (n=5). Dogs from group B were given doxorubicin 30mg/m² intravenously, every 21 days, until a cumulative dose of 180mg/m² or 240mg/m² was reached. Dogs from group A (used as control) were administered saline intravenously at the same group B intervals. As soon as myocardium dysfunction was observed in dogs from group B, determined by a shortening fraction below 20%, increased E-point to septal separation above 0.7cm, and increased end-systolic left ventricular volume index (61.4ml/m²), a 24-hour Holter was recorded in all dogs from both groups. There was an increase of minimum heart rate (44.6%) and mean... |

In the initial stage of traumatic brain injury, the use of 1.0 inspired oxygen fraction (FiO2) is indicated. However, high FiO2 has been correlated with atelectasis. Thus, the effects of FiO2= 1.0 and FiO2= 0.6 on the cardiopulmonary function in propofol-anesthetized dogs with high intracranial pressure (ICP) 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) followed by a continuous rate infusion (0.6mg.kg-1.minute-1). An increase in the ICP was induced by temporary obliteration of the right jugular vein (OJv) 50 minutes after induction of anesthesia. The measurement was taken twenty minutes after OJv (T0) and then at... |
