Some success has been demonstrated using percutaneous electrical nerve stimulation (PENS) to treat trigeminal-mediated headshaking (TMHS) in horses. The aim of this study is to determine whether electroacupuncture (EA) can provide similar remission from the pain of this debilitating condition. EA is less invasive than PENS and can be carried out in the stable yard without the need for a hospital setting and expensive equipment. Six horses and ponies showing clinical signs of headshaking were treated with electroacupuncture of the infraorbital nerve under light sedation. The nerve was stimulated with alternating 2 and 80 Hz frequencies for a period of 25 min with the current adjusted so that there was visible twitching of the nostrils and/or lips. Follow-up treatments were given when the signs recurred or 4–7 days later if there was no initial response. The procedure was well tolerated by all the horses. Once a response was achieved, the period of remission often increased with subsequent treatments. Median remission time for the first treatment was 5.5 days (mean 7.6 days, range 0–13 days, n = 6). second treatment 8.5 days (mean 10.6 days, range 7–21 days, n = 6), third treatment 18 days (mean 28.8 days, range 6–71 days, n = 6), fourth treatment 47.5 days (mean 10 weeks, range 11 days–23 weeks, n = 6), fifth treatment 13 weeks 5 days (mean 18 weeks 5 days, range 5 weeks–46 weeks, n = 5), sixth treatment 24 days (mean 26 days, range 13–41 days, n = 3). The three horses that started treatment in 2015 received a single treatment in April or May of 2016 and were still asymptomatic at the end of the study period in October 2016. It was concluded that EA of the infraorbital nerve is an effective and well-tolerated treatment for the management of horses considered to be experiencing trigeminal-mediated headshaking. 相似文献

Oxaliplatin (OXL) therapy often causes side effects including chronic peripheral neuropathy. We investigated the pain-relieving effects of recombinant human lactoferrin (rhLf) as well as a long-acting IgG-Fc fused rhLf (rhLf-Fc) on OXL-induced neuropathic pain. We used the hLf in this study, because the homology between mouse Lf and hLf is higher than that of bovine Lf. In addition, rhLf-Fc is expected to enhance the analgesic effect due to the life extension effect in the body. We administered OXL (2 mg/kg, i.v.) to mice twice weekly for 4 weeks. Phosphate buffered saline (PBS), rhLf (100 mg/kg, i.p.) or rhLf-Fc (100 mg/kg, i.p.) was administered once a week from day 15 to 32. We also assessed the continuous infusion of same drugs (10 mg/kg/day) into the external jugular vein by using an osmotic pump. Both of rhLf and rhLf-Fc significantly reduced the hypersensitivity to mechanical stimulation when they were administered intraperitoneally. The continuous infusion of rhLf resulted in a more pronounced effect. Histopathological analysis of sciatic nerve showed that both rhLf and rhLf-Fc tended to reduce nerve fiber damage, but no significant difference was observed in nerve fiber cross-sectional area. Therefore, it was suggested that rhLf or rhLf-Fc injection could be an option for controlling neuropathic pain, which are side effects of OXL. 相似文献

ObjectiveWe aimed to assess the efficacy and benefit-risk profile of pregabalin (PGN) to reduce the clinical signs of central neuropathic pain (CNeP) as reflected by scratching episodes in dogs with symptomatic syringomyelia (SM).Study designRandomized, double-blind, placebo-controlled crossover study.AnimalsA total of 12 client-owned Cavalier King Charles Spaniels (age, 1.1–7.4 years, bodyweight, 8.2–10.8 kg) with magnetic resonance imaging-confirmed SM and clinical signs of CNeP.MethodsDogs were randomized to either PGN 150 mg or placebo for 25 days, followed by 48 hour washout period before crossover to the alternate phase of 25 days. The primary outcome was defined as number of scratching events during 10 minutes of video-recorded physical activity. Treatment effect was estimated using a generalized estimation equation model. Benefit-risk and quality of life assessments were obtained through owner interviews focusing on potential adverse events.ResultsThe treatment effect estimate was an 84% (95% confidence interval = 75–89%) reduction in mean number of scratching events relative to baseline compared with placebo (p < 0.0001). Owner-assessed satisfactory quality of life was status quo and rated as ‘good’ or ‘could not be better’ in six/11 dogs and improved in four/11 dogs. The most prevalent adverse events were increased appetite in nine/12 dogs and transient ataxia in nine/12 dogs. There was one dog withdrawn by the owner 7 days after crossover to PGN owing to persistent ataxia. No dogs needed rescue analgesia during the trial.Conclusions and clinical relevancePGN is superior to placebo in the reduction of clinical signs of SM-related CNeP in dogs. At a dose range of 13–19 mg kg–1 orally twice daily, the encountered adverse events were acceptable to all but one owner. 相似文献

Objective The aim of this study was to describe the practices, attitudes and beliefs of Queensland veterinarians in relation to postoperative pain and perioperative analgesia in dogs. Methods One veterinarian from each of the 50 randomly selected Queensland veterinary practices was enrolled after selection by convenience sampling. Results The study response rate was 94.3%. Demeanour, vocalisation and heart rate were the most common postoperative pain assessment tools used, even though the most sensitive tools were considered to be demeanour, heart rate and respiratory rate. Only 20% of respondents used formalised pain scoring systems. Preoperative analgesic administration was always used by 72% of respondents. There was marked variability in the frequency with which analgesia was administered perioperatively for ovariohysterectomy. Only 24% of veterinarians discharged animals with ongoing analgesia even though 38% agreed that pain is still present 7 days postoperatively. Multimodal analgesia was used by 82% of respondents. Epidural and local anaesthetic analgesic techniques were not being utilised by any respondents. Conclusions These results indicate that management of postoperative pain in dogs in Queensland is frequently suboptimal and, at times, is not consistent with the veterinarian's attitudes and beliefs. Continuing education into analgesic use and pain evaluation may be effective in addressing this. 相似文献

Brucella suis is an emerging, zoonotic disease predominantly affecting dogs and humans that engage in feral pig hunting in Australia and other countries. Although B. suis infection in dogs shares some clinical similarities to the host-adapted species (B. canis), B. suis remains an incompletely understood pathogen in dogs with limited published data on its pathogenesis and clinical features. This case series describes the presentations, diagnosis, and clinical management of B. suis infection in three dogs: (1) a bitch with dystocia, abortion and mastitis; (2) an entire male dog with septic arthritis and presumptive osteomyelitis; and (3) a castrated male dog with lymphadenitis. Unique features of these cases are reported including the first documented detection of B. suis from milk and isolation from lymph nodes of canine patients, as well as the follow-up of pups born to a B. suis-infected bitch. Consistent with previous reports, all three dogs showed a favourable clinical response to combination antibiotic therapy with rifampicin and doxycycline. Individually tailored drug regimens were required based on the clinical presentation and other factors, including owner expectations and compliance with therapy as well as a zoonotic risk assessment (generally considered low, except around time of whelping). The authors include their recommendations for the clinical management of dogs that are at-risk or seropositive for B. suis with or without clinical signs or laboratory-confirmed infection. 相似文献

ObjectiveTo assess the effect of adjunctive gabapentin (GBP) on pain after thoracolumbar intervertebral disc surgery in dogs.Study designProspective, randomized, controlled, clinical, ‘blinded’ trial.AnimalsSixty-three client owned dogs undergoing hemilaminectomyMethodsDogs were assigned to two treatment groups. The GBP group received gabapentin 10 mg kg?1 orally every 12 hours starting before anaesthesia; the placebo (P) group received empty gelatin capsules. Background analgesia was initiated with intravenous levomethadone 0.6 mg kg?1 (as the combination ‘L-Polamivet) at anaesthesia induction, followed by a fentanyl patch and levomethadone 0.2 mg kg?1 subcutaneously every 8 hours for 24 hours. Pain was assessed by the short form of the Glasgow Composite Measure Pain Score (CMPS-SF) without the gait category, and by a Visual Analogue Scale (VAS). Serum GBP concentrations and cortisol concentrations were measured. Statistical analyses utilized chi square test, Kolmogorov-Smirnov test, two-way analysis of variances for repeated measurements, Wilcoxon test and Friedmann test as relevant. Correlations were tested by Spearman's and Pearson's correlation coefficient. p< 0.05 was considered significant.ResultsMedian CMPS-SF was lower in group GBP than in group P on days 0.5, 1, 4 and 5. However, CMPS-SF and VAS were not significantly different between groups. Both pain scores decreased significantly over time. Cortisol concentrations were not significantly different between groups. Minimum serum concentrations of GBP fell below the detection limit of 1 μg mL?1 in 6 of 29 and 7 of 28 dogs at 24 and 72 hours, respectively.Conclusions and clinical relevance10 mg kg?1 GBP orally twice a day did not result in a detectable reduction in pain behaviour compared to background opioid analgesia alone, although a trend to lower pain levels (p < 0.1) was present. Further studies are needed to determine if this is related to effective background analgesia or an ineffective dose of GBP. 相似文献

: Infection with Angiostrongylus vasorum was diagnosed at necropsy on a dog that died from acute pulmonary haemorrhage, and on recovery of L1 larvae by Baermann examination of faeces from two dogs, one of which had abdominal pain and retroperitoneal haemorrhage, while the other had right-sided heart failure due to cor pulmonale. The presenting signs included syncope (one dog), exercise intolerance (two dogs), cough (two dogs), abdominal pain (one dog) and depression (one dog). One-stage prothrombin time and activated partial thromboplastin time were prolonged in two dogs, buccal mucosal bleeding time was prolonged in one dog and globulin was elevated in all three dogs. Two dogs were treated with fenbendazole and recovered. 相似文献

This report describes a clinically useful modified composite pain score (MCPS) for horses with hoof pain. The horse in this report initially suffered from acute pain from a subsolar seroma as well as suspected pain from chronic laminitis. Following surgical debridement, corium prolapsed through the wound and it became infected. During the course of conventional hoof and wound management, the pain experienced by the patient was refractory to nonsteroidal anti‐inflammatory drugs. Using the MCPS as a guide, inflammatory and neuropathic pain states were identified and multimodal analgesia was employed in response to the varying pain states. Drugs used for the anti‐inflammatory pain management protocol included firocoxib, butorphanol, phenylbutazone, aspirin and fish oil. Neuropathic pain modulators included parenteral and local anaesthetics, pentoxifylline, ketamine and gabapentin. Composite pain scoring in horses, which includes observational, physiological and interactive components, may have greater sensitivity for demonstrating response to therapy when multiple types and stages of pain exist. 相似文献

Objective To compare the effect of topical latanoprost, intracameral carbachol, or no adjunctive medical therapy on the development of acute postoperative hypertension (POH) and inflammation after routine phacoemulsification and aspiration (PA) of cataracts in dogs.
Design Retrospective study.
Procedures Dogs received either one drop of topical 0.005% latanoprost (21 dogs, 39 eyes), an intracameral injection of 0.3 mL of 0.01% carbachol (15 dogs, 30 eyes), or no adjunctive therapy (46 dogs, 90 eyes) immediately following PA of cataract(s). Intraocular pressure (IOP) was measured in all dogs 2 and 4 h after surgery. IOP was measured and aqueous flare assessed at 8 am the day after surgery.
Results Carbachol-treated dogs had significantly higher mean IOP (33.2 ± SD 20.8 mmHg) 2 h after surgery than dogs receiving no adjunctive therapy (22.0 ± SD 14.1 mmHg) ( P = 0 .049). There were no significant differences in IOP among groups at any other time point. There were no significant differences in number of POH episodes between dogs treated with carbachol (47%), latanoprost (29%), or dogs that received no adjunctive therapy (33%). There were no significant differences in mean aqueous flare grade between eyes treated with latanoprost (1.7 ± SD 0.4) or carbachol (1.4 ± SD 0.6), and eyes that received no adjunctive therapy (1.7 ± SD 0.4).
Conclusions Topical 0.005% latanoprost or intracameral injection of 0.3 mL of 0.01% carbachol after PA in dogs did not reduce POH or increase intraocular inflammation compared to dogs not receiving adjunctive therapy after PA of cataracts. 相似文献

OBJECTIVE: To compare the peri- and post-operative (72 hours) analgesic effects of injectable and orally administered carprofen and meloxicam for ovariohysterectomy in dogs. STUDY DESIGN: Prospective, randomized clinical study. ANIMALS: Forty-three dogs undergoing elective ovariohysterectomy. MATERIALS AND METHODS: Dogs were randomly assigned to receive pre-operative carprofen, meloxicam or sterile saline by subcutaneous injection. Pre-anaesthetic medication was intramuscular acepromazine (0.02 mg kg(-1)) and methadone (0.2 mg kg(-1)). Anaesthesia was induced with either thiopentone or propofol injected to effect, and maintained with isoflurane in oxygen. Visual analogue scores (VAS) for pain and sedation were recorded at 1, 2, 3, 4 and 6 hours following tracheal extubation. Oral medication with the same treatment was continued post-operatively for 3 days, with VAS scores for pain being recorded before, and 2 hours after treatment on each day. Differences between group age, body mass, duration of general anaesthesia, time from treatment injection to tracheal extubation and time from treatment injection to first oral treatment were analysed using one-way analysis of variance and Kruskal-Wallis test. Visual analogue scores for pain and sedation were analysed using a re-randomization method. The significance level was set at p < 0.05. RESULTS: Meloxicam-treated subjects had lower mean VAS than the control group at 2 and 6 hours following tracheal extubation. Control group VAS were more varied than meloxicam scores (at 6 hours) and carprofen scores (at 3 and 6 hours). On the first post-operative day, pre- to post-treatment VAS scores decreased significantly after meloxicam. On day 3, scores in the meloxicam-treated group were significantly lower than control values after treatment. Changes in pre- to post-treatment VAS were greater in animals receiving either meloxicam or carprofen compared with those given saline. CONCLUSIONS AND CLINICAL RELEVANCE: Both carprofen and meloxicam provided satisfactory analgesia for 72 hours following ovariohysterectomy in dogs. 相似文献

ObjectiveTo compare the effects of tramadol alone, or in combination with dipyrone or meloxicam, on postoperative pain and analgesia requirement after unilateral mastectomy with or without ovariohysterectomy in dogs.Study designProspective, randomized, clinical study.AnimalsTwenty seven bitches undergoing unilateral mastectomy with or without ovariohysterectomy.MethodsAnesthesia was induced with propofol and maintained with isoflurane and a constant rate infusion of morphine. Before the end of surgery, dogs were randomly assigned to receive intravenous tramadol alone (3 mg kg?1, group T), combined with dipyrone (30 mg kg?1, group TD) or meloxicam (0.2 mg kg?1, group TM). Dogs received additional doses of tramadol (groups T and TM) or tramadol with dipyrone (group TD) at 8 and 16 hours after extubation. Postoperative pain was assessed by a blinded observer before anesthesia (baseline) and at 1, 2, 3, 4, 6, 8, 12, 16 and 24 hours after extubation using a visual analog scale (VAS) and a modified Glasgow scale. Rescue analgesia (morphine, 0.5 mg kg?1) was administered if the Glasgow pain score was >3.5.ResultsThere were no significant differences among groups in pain scores evaluated by the VAS or the Glasgow scale. In groups T, TD and TM, pain scores were significantly higher than at baseline for 6, 8 and 2 hours, respectively. Rescue analgesia was administered to 3/9, 2/9 and 1/9 dogs in groups T, TD and TM, respectively (p > 0.05) [Correction added on 15 August 2013, after first online publication: ‘T, TM and TD’ was changed to ‘T, TD and TM’.].Conclusions and clinical relevanceUnder the conditions of this study, tramadol alone or in combination with dypyrone or meloxicam provided effective analgesia for 24 hours in most dogs after unilateral mastectomy with or without ovariohysterectomy. Further evaluation of combination therapies is needed in larger groups of dogs. 相似文献

Abstract Twelve dogs with generalized demodicosis were treated with oral administration of ivermectin, 0.4 mg kg-1 of body weight given once every 24 h. Results of skin scrapings were used to determine whether administration of ivermectin should be continued or stopped. Dogs that were free of clinical signs of demodicosis 12 months after administration of ivermectin was discontinued were considered cured. Five dogs were cured. The medían duration of treatment was 15 weeks (range 5–21 weeks). Seven dogs were failures, with five relapsing 3–11. 5 months after treatment was stopped, and two having persistent demodicosis in spite of treatment. Mild ivermectin toxicosis developed in one dog after 5 weeks of treatment; side-effects resolved shortly after the treatment was stopped. Resumen Se trataron doce perros con demodicosis generalizada con ivermectina oral, 0.4 mg/Kg de peso corporal una vez cada 24 h. Se realizaron raspados cutáneos para déterminar si debia retirarse o continuar con la administración de ivermectina. Se consideraron curados aquellos perros sin sintomatologia de demodicosis 12 meses después de retirar la terapia con ivermectina. La duración medía del tratamiento con ivermectina fue de 15 semanas (rango de 5–21). Se fracasó en siete perros, con cinco recidivas a los 3–11, 5 meses después de parar la terapia y dos con demodicosis persistente a pesar del tratamiento. Un perro desarrolló una toxicosis leve a la ivermectina a las 5 semanas del tratamiento; los efectos secundarios desaparecieron al poco de retirar el tratamiento.

OBJECTIVE: To describe a modified ventral stabilization technique for surgical management of atlantoaxial subluxation in dogs and to evaluate the outcome. STUDY DESIGN: Retrospective clinical study. SAMPLE POPULATION: Nineteen client-owned dogs. METHODS: Medical records of 19 dogs with a radiographic diagnosis of atlantoaxial subluxation surgically managed by a modified ventral fixation technique (cortical screws, Kirschner wires, polymethylmethacrylate) were reviewed. Data on pre- and post-operative neurologic status, surgical technique, and complications were retrieved. Follow-up evaluation was performed at approximately 1 month. Telephone interview of the owner was used for long-term assessment (median follow-up for 17 surviving dogs was 10.5 months). RESULTS: Adequate reduction and stabilization was achieved in all dogs based on radiographic assessment immediately after surgery. Improved neurologic outcome occurred in 16 dogs at 1 month and in 15 dogs at follow-up; 2 dogs died of post-operative complications within 24 hours of surgery. One dog was euthanatized at the owners' request because of recurrent neck pain associated with implant failure after 1 month. Two dogs required surgery to remove broken and migrated implants, but further stabilization was not necessary. CONCLUSIONS: Adequate stabilization and improved neurologic outcome was achieved in most dogs. However, on account of the small size of the study and the variable neurologic signs of the dogs on admission, the surgical technique described could not be compared to those previously reported. CLINICAL RELEVANCE: The surgical technique described is an effective means of surgical treatment for atlantoaxial subluxation. 相似文献
