The objectives of this study were to compare the clinical hematological changes under anesthetization in Crucian carp (Carassius auratus auratus) due to treatment with local anesthetics. Our data indicate  that the values declined significantly (P ＜  0.05) with dissolved oxygen amount after anesthetization, furthermore, the values increased significantly (P ＜  0.05) with blood carbon dioxide amount after anesthetization with local anesthetic. The values of platelet (PLT), red blood cell distribution width coefficient of variation (RDW-CV) significantly declined (P ＜  0.05) white blood cells (WBC), red blood cells (RBC), hemoglobin (HGB), hematocrit (HCT), mean corpuscular volume (MCV), mean corpuscular hemoglobin (MCH), mean corpuscular hemoglobin concentration (MCHC). Red blood cell distribution width standard deviation (RDW-SD), plateletcrit(PCT), mean platelet volume (MPV) significantly increased (P ＜ 0.05) but PLT values dropped to 30% of the originally worth with local anesthetics. 

 

Key words: Blood property tests, carbon dioxide amount, Crucian carp, dissolved oxygen amount, local
