RÉSUMÉ
OBJECTIVE: To investigate the postoperative analgesic effects of preemptive dexketoprofen trometamol in dogs subjected to ovariohysterectomy (OHE). MATERIAL AND METHODS: Seventeen adult bitches of various breeds were used in this study. The dogs were randomly allocated into of two groups. Subjects in the dexketoprofen trometamol (DEX) group (n=10), received intravenous (i.v.) dexketoprofen trometamol, 1 mg/kg, 15 minutes before premedication, while those assigned to the control (C) group (n=7) were given no analgesics prior to premedication. Pain level was assessed by two researchers before the administration of anaesthesia (15 minutes before start) and 0, 1, 2, 4 and 6 hours after surgery. A modified University of Melbourne Pain Scale (UMPS) was used to evaluate pain in both groups. RESULTS: Serum cortisol level changed from 0 to 1 h and from 0 to 1 to 4 h were compared between the groups; the increase in the C group was statistically significant. The modified UMPS was applied to both groups at baseline and postoperative 1, 2, 4 and 6 h. According to this test, the values for DEX were significantly lower than controls at 4 and 6 h (p<0.001). CONCLUSION: Stable vital signs with unchanged biochemical parameters on dexketoprofen administration are a promising finding. The clinical advantage shown by the pain scale difference and the low serum cortisol levels should qualify dexketoprofen for preemptive pain management in dogs (Tab. 5, Fig. 2, Ref. 30).

The study included 12 clinically healthy, adult male dogs of various breeds, admitted to our clinic for castration. After general anesthesia with sevoflurane, we administered epidural fentanyl (1 mcg/kg) to fentanyl group, while lidocaine group was given Lidocaine (3 mg/kg) through epidural administration. When hemodynamic parameters were stabilized, first measurements were recorded at minutes 0, 15, 30, 60 in both groups, which included Heart Rate (HR), body temperature, systolic blood pressure (SBP), diastolic blood pressure (DBP), mean arterial pressure (MAP), sodium (Na+), potassium (K+), glucose (GLC), and hemoglobin (HB) measurements. In addition, serum samples were obtained from arterial blood at the same measurement times, and pH, pO2, pCO2, HCO3, %O2 Saturation, BE levels were measured. For hematological analysis, WBC, RBC, HCT, THR counts were performed. For serum biochemical analysis, venous blood samples were collected at minutes 0 and 60 and CK, TP, UREA, ALT, AST, ALB, GGT, CRE, CK-MB parameters were assessed using auto-analyzer. Moreover, cortisol levels were measured in the samples collected at minutes 0, 30, and 60.Mean arterial blood pressure values measured at minutes 15, 30 and 60 were found significantly lower in the fentanyl group (p<0.01). In conclusion, we suggest that epidural anesthesia with lidocaine and fentanyl can provide an effective and safe option in high-risk groups (Tab. 5, Fig. 1, Ref. 24).
