Contenção farmacológica de jacaré tinga Caiman crocodilus linnaeus (crocodylia: alligatoridae) com propofol

Abstract

It is proposed to evaluate the induction period, muscle relaxation and recovery, as well as adverse effects of propofol in jacaré-tinga (Caiman crocodilus) using the cervical sinus vertebral as a means of application. Ten specimens were used of caiman who received a dose of 5 mg / kg of propofol intravenously in vertebral venous sinus in the neck. Evaluated the physiological parameters of cloacal temperature and heart and respiratory rates, as well as the reaction postural righting, muscle relaxation, head support and response to nociceptive stimulation. Evaluated the periods of sensory and motor block, and calculated the latency periods, skilled anesthesia and recovery. In this study don t occurred sensory block in the animals, motor block was 88.5 ± 55.35 minutes, the latency period was 57 ± 9.77 seconds, there was no reasonable period of anesthesia and recovery was 34.1 ± 0.2 minutes. Apnea occurred in 90% of the animals and decreased respiratory rate. It is concluded that the use of propofol at a dose of 5 mg / kg applied to the cervical sinus vertebral in jacaré-tinga Caiman crocodilus produces a rapid period of latency with good muscle relaxation and rapid recovery does not cause sensory block and its adverse effect cause was apnea.
