Physiological Response Of Elasmobrachs During Propofol Immersion, Matthew Levendosky

Electronic Theses and Dissertations

Sensory experiments require anesthesia so the animal is immobilized, however fish anesthetics have shown to depress sensory responses. Newer anesthetics may offer similar anesthetic relief, but differ in means of action so sensory responses may be unaffected. Propofol has been used intravenously on small elasmobranchs but may provide prolonged effects if used as an immersion anesthetic. Objectives of this study were 1. Determine appropriate concentration of anesthetic to minimize induction and recovery for animals anesthetized at a surgical plane of anesthesia and 2. Measure physiological response of the pupil to light stimuli during anesthetic immersion. To address these objectives, I …
