The influence of the duration of the preoperative time spent in the veterinary clinic without the owner on the psychogenic and oxidative stress in dogs

摘要

The objective of this study was to evaluate the influence of the dog’s long-term separation from its owner in the novel environment on the occurrence of psychogenic and oxidative stress. Group I dogs (n=9) were brought to the veterinary clinic and stayed in a kennel room for 12 hr before the surgery, and group II dogs (n=9) ?for 10 min before the surgery. Physiological parameters (heart rate (HR) (beats/min) and respiratory rate (fR) (breaths/min)) were measured and blood sampling was done 12 hr before the surgery (T0) for group I dogs and 10 min before the surgery (T1) for both groups dogs. Oxidative stress index (OSI) was determined using spectrophotometer and Rel Assay Diagnostics kits by measuring TAS ant TOS in blood plasma. The cortisol level was measured using AIA-360 Automated Immunoassay Analyzer and ST AIA-pack Cortisol assays. Group I dogs’ HR and fR were elevated at T0 and T1, and group II dogs’?at T1 compared to physiological range. OSI and cortisol levels in group I dogs was higher at T1 compared to T0 (P0.05). There was no significant difference in cortisol level between group I at T0 and group II at T1 (P0.05). It might be concluded that dogs’ longer stay in the novel environment without the owner induced significant changes in OSI and cortisol level, which could lead to slow wound healing and the occurrence of systemic diseases.
