Abstract: In order to explore the clinical anesthesia drug combination and anesthesia effect of aquatic turtles，a trial was conducted using Dexmedetomidine（0.05 mg/kg）combined with Afaxalone（5 mg / kg）to anesthetize nine Trachemys scripta elegans.The time and behavioral manifestations of the experimental animals during the induction period，anesthesia period and recovery period were recorded respectively to evaluate the effects of the drugs on sedation，analgesia and muscle .Blood tests and detection of body indicators such as heart rate were conducted on the experimental animals to assess the effect of anesthesia on animal physiological constants. The results showed that the combination of the drugs has an anesthesia induction period of（12.11±2.86）min for Trachemys scripta elegans，and can provide an effective anesthesia induction of（51.89±7.21）min. During the anesthesia process，the experimental animals was stable and showed no adverse reactions. After intramuscular injection of the Atipamezole（0.5 mg/kg），the animals fully recovered after（18.22±4.42）min. The overall effect of anesthesia operation on the blood biochemical indicators and heart rate of the experimental was not significant，indicating that this combination and dosage are suitable for clinical anesthesia of aquatic turtles.
