Intra-and post-operative analgesic effects of pre-operative administration of carprofen were investigated in 16 medetomidinepremedicated dogs undergoing elective ovariectomy. Dogs were randomly allocated into carprofen (n=8; 4 mg/kg, intramuscularly) or placebo group (n=8). After medetomidine (1000 mg/m 2 , intramuscularly) premedication, they were induced with propofol (1 mg/kg, intravenously) and maintained with isoflurane (F E 'ISO 1.0 %) in 100% oxygen. During anaesthesia, the analgesia was assessed in terms of changes in heart rate, respiratory rate and arterial blood pressure as a response to the surgery. Assessments of post-operative sedation (simple numerical rating scale) and pain (multifactorial pain scale) were made at 15 minutes, 30 minutes, 1, 2, 3, 4, 5, and 6 hours after the surgery. In addition, pulse rate, respiratory rate and body temperature were measured at the same time. During anaesthesia, lower heart rate, respiratory rate and mean arterial blood pressure and higher tidal volume of respiration were observed in the carprofen group. Post-operative pain score was relatively low in both groups of dogs, however it was higher, but not significantly, in the placebo group. There was no difference between the groups in terms of respiratory and pulse rate after surgery. The post-operative sedation score was higher in the placebo group only in the early post-operative period, most probably due to misinterpretation of pain behaviour. Carprofen together with other anaesthetic drugs provided sufficient intra-operative analgesia only until major painful surgical stimulus occurred, after which analgesia had to be supplemented with a subanaesthetic dose of ketamine. Comparing to that analgesia was insufficient in the placebo group throughout the procedure. The post-operative pain scoring system was probably not sensitive enough to detect the differences between the groups; however, the effects of other drugs that extended in the post-operative period may be responsable for a low postoperative pain score in both groups of dogs.

In this study the authors aimed to compare the efficiency of carprofen, ketoprofen and vedaprofen for alleviating postoperative pain in bitches submitted to ovariohysterectomy (OH). Pre- and postoperative assessment of pain was made using serum levels of cortisol and glucose, the visual analogue scale (VAS) and the University of Melbourne pain scale (UMPS) in twenty-one bitches undergoing OH. Dogs were randomly assigned to one of three groups: vedaprofen at 0.5mg kg-1, carprofen at 2.2mg kg-1 or ketoprofen at 2.2mg kg-1. All analgesics were given orally 2 hour before surgery. Assessments were made before surgery and at 1, 2, 3, 4, 5, 6, 7, 8, 12 and 24 hours post-extubation. No dog of this study required additional doses of analgesics. There were no significant differences on serum cortisol and glucose concentrations among groups or from basal values, excepted one hour after extubation. No significant differences on pain scores were observed. It was concluded that vedaprofen provide...

Objective To assess the analgesic efficacy and adverse effects of a novel, long-acting sufentanil preparation in dogs undergoing ovariohysterectomy (OHE). Study design Blinded, positively controlled, randomized field trial with four parallel treatment groups. Animals Eighty client owned dogs undergoing elective OHE randomly allocated into four treatment groups (each n ¼ 20). Conclusions The long-acting preparation of sufentanil provided excellent post-operative analgesia that was significantly better than that provided by carprofen. However, use of this formulation, in the anaesthetic technique used in the study, resulted in a relatively high incidence of adverse effects. Clinical relevance Full mu (MOP) opioid agonists provide significantly better post-operative analgesia than nonsteroidal anti-inflammatory drugs after moderately painful surgery. However, the widely recognized adverse effects of opioids may preclude the use of these agents.

Comparison of analgesic efficacy of 3 non-steroidal analgesic drugs (carprofen, vedaprofen and tepoxalin) were performed in 40 dogs after ovariohysterectomy. Oral administration of placebo (sugar pill), carprofen (4.4 mg/kg/day), vedaprofen (0.5 mg/kg/day), or tepoxalin (20 mg/kg/day) for 3 days were performed in dogs recovering from ovariohysterectomy. Numerical pain scores (descriptive and composite pain scores) were measured in blinded fashion by three investigators at 0, 12, 24, 36, 48 and 60 hrs following the recovery. The average descriptive and composite pain scores of dogs treated with carprofen or tepoxalin were significantly lower than that of the control group (p 0.05). Serum PGE2 measurement at 60-hrs post-operation significantly decreased in tepoxalin-treated group, whereas no difference was detected in the carprofen- and vedaprofen-treated groups. This study indicates thatboth carprofen and tepoxalin are helpful for canine postoperative pain management.
A systematic review of analgesia practices in dogs undergoing ovariohysterectomy
Veterinary World, 2018
Aim: This was a systematic review conducted to evaluate the analgesic drugs and techniques used in the management of pain in dogs undergoing ovariohysterectomy. Materials and Methods: Systematic searches in PubMed, Google Scholar, and ScienceDirect were conducted for peer-reviewed articles written in English and published from 1995 to 2015. The key search words were dogs, ovariohysterectomy, pain, and analgesics. This was followed by a manual search of the references within the primary data sources. Inclusion and exclusion of studies and data extraction were performed independently by two reviewers. All randomized studies evaluating the effects of analgesics during ovariohysterectomy in dogs were included. Results: A total of 31 trials met the criteria and were, therefore, included in the study. Data on the type of analgesic drugs used, the technique of administration, and the need for rescue analgesia were extracted from the papers. Individual analgesic protocols were used in 83.9% of the studies compared to multimodal drug therapy, which was used in 16.1% of the studies. Opioids were used in 39.0% of studies, nonsteroidal anti-inflammatory drugs (NSAIDs) in 19.4%, a combination of NSAIDs and opioids in 19.4%, local analgesics in 6.5%, and acupuncture in 3.2% of the studies. Drug administration was done using three approaches that included pre-operative (64.5%), post-operative (22.6%) as well as combined pre-and post-operative approach (12.9%). In 77.4% of the studies, administration of analgesics was done once, while in 12.9%, it was done as a 72-h post-operative course. 24-h and 48-h courses of post-operative pain therapy were done in 6.5% and 3.2% of the studies, respectively. About 57% of the dogs in the control groups required rescue analgesia as compared to 21.6% in the single and 11.3% in multimodal drug therapy groups. The requirement for rescue analgesics was highest in dogs treated using acupuncture (43.8%) and lowest in dogs treated using NSAID-opioid combination (8.6%). Fewer dogs among those that received pain medication preoperatively and postoperatively required rescue analgesia compared to those in groups given drugs before and after surgery only. More dogs (26.4%) among those given analgesics only once postoperatively required rescue analgesia as compared to those that received analgesics daily for 72 h (4.4%). Conclusions: This study provides evidence that opioids are the mainstream analgesic drugs used in managing acute post-operative pain in dogs' post-ovariohysterectomy. In addition, multimodal drug therapy, particularly, NSAID-opioids combination is more effective for pain management than single drug administration. Administering analgesics both before and after surgery is associated with better outcomes and so is a protracted course of post-operative pain therapy. Although these practices should be encouraged, controlled studies should be conducted to conclusively determine the best practices for pain management in dogs undergoing ovariohysterectomy.

Postoperative analgesia in the cat after ovariohysterectomy by use of carprofen, ketoprofen, meloxicam or tolfenamic acid The adequacy of postoperative analgesia was assessed in 40 cats following ovariohysterectomy. A t extubation, cats were given one dose of carprofen, ketoprofen, meloxicam or tolfenamic acid. Postoperative analgesia was assessed using visual analogue scale (VAS) scoring for pain and sedation; measurement of mechanical nociceptive thresholds at the wound; recognition of the requirement for rescue intervention analgesia; and an overall clinical assessment score at 18 hours. VAS pain scores were low throughout the trial, with no significant differences found between the groups. Postoperative mechanical nociceptive thresholds decreased significantly from baseline in all four groups, with no significant differences between the groups. One cat in each of the tolfenamic acid, ketoprofen and meloxicam groups required rescue intervention analgesia. Nine out of 10 cats in all four groups were classified as having desirable overall clinical assessment scores. In summary, all four drugs provided good postoperative analgesia, although none was able to prevent postoperative wound tenderness.

The objective of this study was to compare the postoperative analgesic effects of dexketoprofen, tramadol, and buprenorphine in dogs undergoing ovariohysterectomy. Seventy-five adult female dogs were randomly assigned to receive an intravenous injection (IV) of 1 mg/kg of dexketoprofen (D), 0.02 mg/ kg of buprenorphine (B) or 2 mg/kg of tramadol (T). Pain assessment was performed during 48 h after ovariohysterectomy using a dynamic interactive visual analogue scale (DIVAS) and Glasgow composite measure pain scale (CMPS-SF). Rescue analgesia was required in 43%, 21%, and 5% of dogs in the B, T, and D groups, respectively, with significant differences between B and D (p = 0.010) groups. The DIVAS and CMPS-SF values of the B group were significantly higher than those of the T and D groups. The most common undesirable effect was dysphoria in dexketoprofen group. Tramadol and dexketoprofen provide superior postoperative analgesia compared with buprenorphine in dogs undergoing ovariohysterectomy.

Objective-To compare analgesic efficacy of preoperative versus postoperative administration of carprofen and to determine, if preincisional mepivacaine epidural anesthesia improves postoperative analgesia in dogs treated with carprofen. Study Design-Blind, randomized clinical study. Animals-Dogs with femoral (n ¼ 18) or pelvic (27) fractures. Methods-Dogs were grouped by restricted randomization into 4 groups: group 1 ¼ carprofen (4 mg/kg subcutaneously) immediately before induction of anesthesia, no epidural anesthesia; group 2 ¼ carprofen immediately after extubation, no epidural anesthesia; group 3 ¼ carprofen immediately before induction, mepivacaine epidural block 15 minutes before surgical incision; and group 4 ¼ mepivacaine epidural block 15 minutes before surgical incision, carprofen after extubation. All dogs were administered carprofen (4 mg/kg, subcutaneously, once daily) for 4 days after surgery. Physiologic variables, nociceptive threshold, lameness score, pain, and sedation (numerical rating scale [NRS], visual analog scale [VAS]), plasma glucose and cortisol concentration, renal function, and hemostatic variables were measured preoperatively and at various times after surgery. Dogs with VAS pain scores 430 were administered rescue analgesia. Results-Group 3 and 4 dogs had significantly lower pain scores and amount of rescue analgesia compared with groups 1 and 2. VAS and NRS pain scores were not significantly different among groups 1 and 2 or among groups 3 and 4. There was no treatment effect on renal function and hemostatic variables. Conclusions-Preoperative carprofen combined with mepivacaine epidural anesthesia had superior postoperative analgesia compared with preoperative carprofen alone. When preoperative epidural anesthesia was performed, preoperative administration of carprofen did not improve postoperative analgesia compared with postoperative administration of carprofen. Clinical Relevance-Preoperative administration of systemic opioid agonists in combination with regional anesthesia and postoperative administration of carprofen provides safe and effective pain relieve in canine fracture repair.

To investigate the analgesic effect of acupuncture (AP) or micro-dose pharmacopuncture (PA), using carprofen or morphine, in bitches undergoing ovariohysterectomy (OHE). Thirty five dogs were randomly assigned to five groups after sedation with acepromazine IM: AP, 0.5 mg.kg-1 of morphine subcutaneously (SC), 4 mg.kg-1 of carprofen SC, and PA with 0.05 mg.kg-1 of morphine or 0.4 mg.kg-1 of carprofen. Anaesthesia was induced with propofol and maintained with isoflurane. Pain was assessed after OHE by a blind observer for 24h, by dynamic visual analogue scale (DIVAS), Glasgow (CMPS-SF), Melbourne (UMPS) and Colorado University pain scale (CSU). Animals reaching 33% of the UMPS score received rescue analgesia with morphine IM. Non parametric data were analysed by Kruskal-Wallis or Friedman tests where applicable, followed by Dunn´s test. Parametric data were analysed by two way ANOVA, followed by Tukey test. There were no differences among groups in number of rescue analgesia. Except f...
