The subject of the study: 1. heart rate frequency dynamics of dogs during pre-medication and general anaesthesia in correlation to animal's breed and sex; 2. similarities in changes of heart rate frequency upon the effect of premedication of Atropine Sulphate and Acepromazine Maleate, as well as the effect of anaesthetic agent Ketamine Hydrochloride in combination with Diazepam. The study examined 66 German Shepherd and Cocker Spaniel dogs. For premedication we used a solution of 0.054% Atropine Sulphate (0.02 mg/kg) combined with 1% Acepromazine Maleate (0.06 mg/kg), injected intramuscularly. For general anaesthesia we used 5% Ketamine Hydrochloride solution (6 mg/kg) combined with 0.6% Diazepam solution (0.6 mg/kg), injected in the subcutaneous vein of the shoulder (v. cephalica). We discovered that under the influence of premedication agents Atropine Sulphate and Acepromazine Maleate, dogs' heart rate frequencies significantly depreciated and the depreciation rate for both breeds was practically the same.
