Anestesia intravenosa total em cães e gatos (revisão de literatura)

Abstract

The total intravenous anesthesia (TIVA) is an anesthetic technique where all the components of general anesthesia are conferred through the use of intravenous drugs. In dogs and cats, compared to inhalation anesthesia, is rarely used in routine, but some of its advantages proven in human medicine have stimulated further studies in the area. The TIVA is able to promote greater hemodynamic stability, smoother recovery, less stress adrenergic, is exempt from environmental pollution and is most appropriate in specific cases like neurosurgerys and lung disorders. On the other hand, it has limitations like the need of different infusion pumps used for each drug, the possibility of individual variation of the patients across the pharmacokinetics of intravenous anesthetics and the difficulty of measuring the plasma concentrations in real time. The most commonly used protocols include the association of propofol and ultra short duration opioids. It can be accomplished by pumps or equipo, bolus or by continuous infusion, and more recently through modern target-controlled infusion techniques, which may provide more accuracy and security to the technique.
