Cardiovascular and Respiratory Effects of Romifidine and/or Xylazine in Ketamine Anaesthesia in Dog: An Experimental Study

To compare romifidine and xylazine premedication in ketamine anesthesia ofthe dog.design: experimental design.animals: fifteen cross-breed dogs.procedures: animals randomly allocated into three groups of five. group g1 premedicatedby xylazine 1 mg/kg, g2 romifidine 40 [g/ kg and g3 romifidine 80 [g/ kgintramuscularly. all animals premedicated with atropine 0.02 mg/kg subcutaneously tenminutes before induction of anesthesia. anesthesia was induced by 15 mg/kg ketamine im.heart rate, respiratory rate, mean arterial blood pressure and eclectrocardiac activity besidequality of anesthesia were evaluated.results: no significant differences were found between three groups around all recordedparameters.conclusions and clinical relevance: usage of different doses of romifidine in caninespecies is possible without any unexpected outcome, 80 [g/ kg of romifidine make betteronset of anesthesia.
