Evaluation of the Anesthetic effects of Cove Oil (Syzygium aromaticum) on Lorestan Newt (Neurergus kaiseri)

The present study describes the anesthetic effects of clove oil (Syzygium aromaticum) in Lorestan newt (Neurergus kaiseri). 6 adult newts (n = 3 for each group) with 13 ± 2 gr were used. The newts were initially divided into two groups, with three newts per group. Each group was subjected to one of two final concentrations [0.3 and 0.5 ml/l] of clove oil. The sedation, anesthesia, and recovery duration were recorded based on the behavioral events after exposing the newts to each aquarium. After inducing anesthesia, the newts were transferred to anesthetic-free aquariums, and recovery duration was recorded. The study showed that anesthesia was achieved in newts across two different concentrations using clove oil. Sedation occurred faster with a higher concentration (0.5 ml/l), taking 7.33 ± 1.52 minutes, compared to 10.66 ± 1.15 minutes with the lower concentration (0.3 ml/l). However, anesthesia lasted longer with the higher dose, averaging 22.66 ± 3.05 minutes, versus 15 ± 2.64 minutes for the lower dose. Recovery was also slower with the higher concentration, indicating stronger anesthetic effects with increased doses of clove oil. Our study supports clove oil as an effective anesthetic in Neurergus kaiseri and recommends its application for achieving suitable induction, anesthetic duration, and recovery profiles.
