Assessment of anesthetic quality in tortoises (Trachemys sp.) submitted to the total intravenous anesthesia (TIVA) protocol for ovariectomy surgery through pre-femoral access.

anesthesia, chelonians, propofol

Tortoise is the generic name used to designate chelonians of underwater life in fresh waters, in distinction from those of salt/marine water (turtles) and those of terrestrial life (tortoises). Although there are tortoises of national origin, the growth of invasive species is a worrying threat to the imbalance of the Brazilian biome. The North American species Thrachemys sp. was introduced in Brazil as a pet, but its dissemination in natural areas occurs throughout the territory, mainly due to the action of abandonment and release by their tutors. Thus, whether as a companion animal or as a control in natural areas as it represents a threat to the national biome, the demand for surgical sterilization of this, and other species of tortoises, is growing, requiring more and more training and development of more modern techniques. and adequate to the physio-anatomical conditions of these animals by the veterinarian. The environmental temperature-dependent metabolic difficulty proves to be a major challenge for anesthesia , and the underwater characteristic of this group generates adaptive apnea conditions that make inhalational anesthesia a questionable option. On the other hand, Propofol has gained strength and studies as a suitable agent for the limiting conditions of the pharmacokinetics of these chelonians. Thus, Total Intravenous Anesthesia (TIVA) can point to a viable and adequate option for anesthesia in these species.
